Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization, Basis of Presentation, and Summary of Significant Accounting Policies	Organization, Basis of Presentation, and Summary of Significant Accounting Policies Organization Malibu Boats, Inc. (together with its subsidiaries, the “Company” or "Malibu"), a Delaware corporation formed on November 1, 2013, is the sole managing member of Malibu Boats Holdings, LLC, a Delaware limited liability company (the "LLC"). The Company operates and controls all of the LLC's business and affairs and, therefore, pursuant to Financial Accounting Standards Board ("FASB") Accounting Standards Codification (“ASC”) Topic 810, Consolidation , consolidates the financial results of the LLC and its subsidiaries, and records a non-controlling interest for the economic interest in the Company held by the non-controlling holders of units in the LLC ("LLC Units"). Malibu Boats Holdings, LLC was formed in 2006 with Malibu's acquisition by an investor group, including affiliates of Black Canyon Capital LLC, Horizon Holdings, LLC and then-current management. The LLC, through its wholly owned subsidiary, Malibu Boats, LLC, is engaged in the design, engineering, manufacturing and marketing of innovative, high-quality, recreational powerboats that are sold through a world-wide network of independent dealers. On July 6, 2017, the Company acquired all outstanding units of Cobalt Boats, LLC (“Cobalt”) further expanding the Company's product offering across a broader segment of the recreational boating industry including performance sport boats, sterndrive and outboard boats. As a result of the acquisition, the Company consolidates the financial results of Cobalt. On October 15, 2018, our subsidiary Malibu Boats, LLC, purchased the assets of Pursuit Boats ("Pursuit") from S2 Yachts, Inc., expanding the Company's product offering into the fiberglass outboard fishing boat market. As a result of the acquisition, the Company consolidates the financial results of Pursuit. Refer to Note 4. The Company reports its results of operations under four reportable segments: Malibu U.S., Malibu Australia, Cobalt and Pursuit, based on their boat manufacturing operations. Basis of Presentation The accompanying unaudited interim condensed consolidated financial statements of the Company have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim condensed financial statements and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all information and disclosures of results of operations, financial position and changes in cash flow in conformity with GAAP for complete financial statements. Such statements should be read in conjunction with the audited consolidated financial statements and notes thereto of Malibu Boats, Inc. and subsidiaries for the year ended June 30, 2018, included in the Company's Annual Report on Form 10-K. In the opinion of management, the accompanying unaudited interim condensed consolidated financial statements reflect all adjustments considered necessary to present fairly the Company’s financial position at March 31, 2019 , and the results of its operations for the three and nine month periods ended March 31, 2019 and March 31, 2018 , and its cash flows for the nine month periods ended March 31, 2019 and March 31, 2018 . Operating results for the three and nine months ended March 31, 2019 , are not necessarily indicative of the results that may be expected for the full year ending June 30, 2019 . Units and shares are presented as whole numbers while all dollar amounts are presented in thousands, unless otherwise noted. Principles of Consolidation The accompanying unaudited condensed consolidated financial statements include the operations and accounts of the Company and all subsidiaries thereof. All intercompany balances and transactions have been eliminated upon consolidation. Pursuit Acquisition On October 15, 2018, our subsidiary Malibu Boats, LLC, purchased the assets of Pursuit from S2 Yachts, Inc. for a purchase price of $100,073 . Pursuit, located in Fort Pierce, Florida, is a leader in the saltwater outboard fishing boat market through its offering of 15 models of offshore, dual console and center console boats. Recent Accounting Pronouncements On July 1, 2018, the Company adopted the new accounting standard, ASC Topic 606, Revenue from Contracts with Customers, and all the related amendments (“ASC 606”) and applied the provisions of the standard to all contracts using the modified retrospective method. The cumulative effect of adopting the new revenue standard was immaterial and no adjustment has been recorded to the opening balance of retained earnings. Prior year information has not been restated and continues to be reported under the accounting standards in effect for those periods. Substantially all of the Company’s revenue continues to be recognized at a point in time when the product is either shipped or received from the Company's facilities and control of the product is transferred to the customer. New controls and processes designed to meet the requirements of the standard were implemented, and the required new disclosures are presented in Note 2. The adoption of ASC Topic 606 did not have a material impact on the amounts reported in the Company's unaudited condensed consolidated financial position, results of operations or cash flows. In February 2016, the FASB issued Accounting Standards Update (ASU) 2016‑02, Leases (Topic 842) . The amendments in this update create ASC Topic 842, Leases , and supersede the requirements in ASC Topic 840, Leases . ASC Topic 842 requires lessees to recognize on the balance sheet a right‑of‑use asset, representing its right to use the underlying asset for the lease term, and a lease liability for all leases with terms greater than 12 months. The guidance also requires qualitative and quantitative disclosures designed to assess the amount, timing, and uncertainty of cash flows arising from leases. The standard requires the use of a modified retrospective transition approach, which includes a number of optional practical expedients that entities may elect to apply. In June 2018, the FASB issued ASU 2018-11, Leases (Topic 842): Targeted Improvement , which provides entities with an additional (optional) transition method to adopt the new lease standard. Under this new transition method, an entity initially applies the new leases standard at the adoption date and recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. The new leases standard is effective for fiscal years beginning after December 15, 2018. Early application is permitted. The Company is currently developing a project plan to guide the implementation of ASU 2016-02. The Company is making progress on this plan including surveying the Company’s businesses, assessing the Company’s portfolio of leases and compiling information on active leases. The Company is currently identifying and implementing appropriate changes to its policies, business processes, systems and controls to support lease accounting and disclosures under Topic 842. The Company does not expect that its results of operations or cash flows will be materially impacted by this standard. The Company expects to record right of use assets and lease liabilities on its consolidated balance sheets upon adoption of this standard, which may be material. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments . This guidance provides specific classification of how certain cash receipts and cash payments are presented in the statement of cash flows. The ASU was applied using a retrospective transition method. The adoption of this ASU on July 1, 2018 did not have a material impact on the Company's consolidated financial statements. In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business . The guidance clarifies the definition of a business that provides a two-step analysis in the determination of whether an acquisition or derecognition is a business or an asset. The update removes the evaluation of whether a market participant could replace any missing elements and provides a framework to assist entities in evaluating whether both an input and a substantive process are present. This guidance will be applied on a prospective basis for transactions that occur after the effective date. The adoption of this ASU on July 1, 2018 did not have a material impact on the Company's consolidated financial statements. There are no other new accounting pronouncements that are expected to have a significant impact on the Company's consolidated financial statements and related disclosures.

Noncontrolling Interest [Abstract]
Non-controlling Interest	Non-controlling Interest The non-controlling interest on the unaudited condensed consolidated statement of operations and comprehensive income represents the portion of earnings attributable to the economic interest in the Company's subsidiary, Malibu Boats Holdings, LLC, held by the non-controlling LLC Unit holders. Non-controlling interest on the unaudited condensed consolidated balance sheets represents the portion of net assets of the Company attributable to the non-controlling LLC Unit holders, based on the portion of the LLC Units owned by such Unit holders. The ownership of Malibu Boats Holdings, LLC is summarized as follows: As of March 31, 2019 As of June 30, 2018 Units Ownership % Units Ownership % Non-controlling LLC Unit holders ownership in Malibu Boats Holdings, LLC 830,152 3.8 % 1,043,186 4.8 % Malibu Boats, Inc. ownership in Malibu Boats Holdings, LLC 20,851,097 96.2 % 20,555,348 95.2 % 21,681,249 100.0 % 21,598,534 100.0 % Issuance of Additional LLC Units Under the first amended and restated limited liability agreement of the LLC, as amended (the "LLC Agreement"), the Company is required to cause the LLC to issue additional LLC Units to the Company when the Company issues additional shares of Class A Common Stock. Other than in connection with the issuance of Class A Common Stock in connection with an equity incentive program, the Company must contribute to the LLC net proceeds and property, if any, received by the Company with respect to the issuance of such additional shares of Class A Common Stock. The Company must cause the LLC to issue a number of LLC Units equal to the number of shares of Class A Common Stock issued such that, at all times, the number of LLC Units held by the Company equals the number of outstanding shares of Class A Common Stock. During the nine months ended March 31, 2019 , the Company caused the LLC to issue a total of 319,956 LLC Units to the Company in connection with (i) the Company's issuance of Class A Common Stock to a non-employee director for his services, (ii) the issuance of Class A Common Stock for the vesting of awards granted under the Malibu Boats, Inc. Long-Term Incentive Plan (the "Incentive Plan"), (iii) the issuance of Class A Common Stock to LLC Unit holders for exchange of their LLC Units, and (iv) the issuance of Class A Common Stock for the exercise of vested stock options granted under the Incentive Plan. During the nine months ended March 31, 2019 , 24,207 LLC Units were canceled in connection with the vesting of share-based equity awards to satisfy employee tax withholding requirements and the retirement of 24,207 treasury shares in accordance with the LLC Agreement. Distributions and Other Payments to Non-controlling Unit Holders Distributions for Taxes As a limited liability company (treated as a partnership for income tax purposes), Malibu Boats Holdings, LLC does not incur significant federal, state or local income taxes, as these taxes are primarily the obligations of its members. As authorized by the LLC Agreement, the LLC is required to distribute cash, to the extent that the LLC has cash available, on a pro rata basis, to its members to the extent necessary to cover the members’ tax liabilities, if any, with respect to their share of LLC earnings. The LLC makes such tax distributions to its members based on an estimated tax rate and projections of taxable income. If the actual taxable income of the LLC multiplied by the estimated tax rate exceeds the tax distributions made in a calendar year, the LLC may make true-up distributions to its members, if cash or borrowings are available for such purposes. As of March 31, 2019 and June 30, 2018, tax distributions payable to non-controlling LLC Unit holders were $559 and $511 , respectively. During the nine months ended March 31, 2019 and 2018 , tax distributions paid to the non-controlling LLC Unit holders were $1,228 and $963 , respectively. Other Distributions Pursuant to the LLC Agreement, the Company has the right to determine when distributions will be made to LLC members and the amount of any such distributions. If the Company authorizes a distribution, such distribution will be made to the members of the LLC (including the Company) pro rata in accordance with the percentages of their respective LLC units.

Business Combinations [Abstract]
Acquisitions	Acquisitions Pursuit On October 15, 2018, the Company completed its acquisition of the assets of Pursuit. The aggregate purchase price for the transaction was $100,073 , funded with cash and borrowings under the Company's credit agreement. The aggregate purchase price was subject to certain adjustments, including customary adjustments for the amount of working capital in the business at the closing date. The Company accounted for the transaction in accordance with ASC 805, Business Combinations . The total consideration given to the former owners of Pursuit has been allocated to the assets acquired and liabilities assumed based on estimates of fair value as of the date of the acquisition. The preliminary measurements of fair value were determined based upon estimates utilizing the assistance of third party valuation specialists, and are subject to change within the measurement period (up to one year from the acquisition date). The Company expects appraisals of tangible and intangible assets and working capital adjustments to be finalized during fourth quarter of fiscal 2019. The following table summarizes the preliminary purchase price allocation based on the estimated fair values of the assets acquired and liabilities of Pursuit assumed at the acquisition date: Consideration: Cash consideration paid $ 100,073 Recognized preliminary amounts of identifiable assets acquired and (liabilities assumed), at fair value: Inventories $ 8,332 Other current assets 350 Property, plant and equipment 17,454 Identifiable intangible assets 57,900 Current liabilities (3,488 ) Fair value of assets acquired and liabilities assumed 80,548 Goodwill 19,525 Total purchase price $ 100,073 The preliminary fair value estimates for the Company's identifiable intangible assets acquired as part of the acquisition are as follows: Estimates of Fair Value Estimated Useful Life (in years) Definite-lived intangibles: Dealer relationships $ 25,400 20 Total definite-lived intangibles 25,400 Indefinite-lived intangible: Trade name 32,500 Total intangible assets $ 57,900 The value allocated to inventories reflects the estimated fair value of the acquired inventory based on the expected sales price of the inventory, less an estimated cost to complete and a reasonable profit margin. The fair value of the identifiable intangible assets were determined based on the following approaches: Dealer Relationships - The value associated with Pursuit's dealer relationships is attributed to its long standing dealer distribution network. The estimate of fair value assigned to this asset was determined using the income approach, which requires an estimate or forecast of the expected future cash flows from the dealer relationships through the application of the multi-period excess earnings approach. The estimated remaining useful life of dealer relationships is approximately twenty years. Trade Name - The value attributed to Pursuit's trade name was determined using a variation of the income approach called the relief from royalty method, which requires an estimate or forecast of the expected future cash flows. The trade name has an indefinite life. The fair value of the definite-lived intangible assets are being amortized using the straight-line method to general and administrative expenses over their estimated useful lives. Indefinite-lived intangible assets are not amortized, but instead are evaluated for potential impairment on an annual basis in accordance with the provisions of ASC Topic 350, Intangibles—Goodwill and Other . The weighted average useful life of identifiable definite-lived intangible assets acquired was 20 years. Goodwill of $19,525 arising from the acquisition consists of expected synergies and cost savings as well as intangible assets that do not qualify for separate recognition. The indefinite-lived intangible asset and goodwill acquired are expected to be deductible for income tax purposes. Acquisition-related costs of $2,846 , which were incurred by the Company in the first nine months of fiscal year 2019 related to the Pursuit acquisition, were expensed in the period incurred, and are included in general and administrative expenses in the consolidated statement of operations and comprehensive income for the nine months ended March 31, 2019. Pro Forma Financial Information (unaudited): The following unaudited pro forma consolidated results of operations for the three and nine months ended March 31, 2019 and 2018, assumes that the acquisition of Pursuit occurred as of July 1, 2017. The unaudited pro forma financial information combines historical results of Malibu and Pursuit, with adjustments for depreciation and amortization attributable to preliminary fair value estimates on acquired tangible and intangible assets for the respective periods. Non-recurring pro forma adjustments associated with the fair value step up of inventory were included in the reported pro forma cost of sales and earnings. The unaudited pro forma financial information is presented for informational purposes only and is not indicative of the results of operations that would have been achieved if the acquisition had taken place at the beginning of fiscal year 2018 or the results that may occur in the future: Three Months Ended March 31, Nine Months Ended March 31, 2019 2018 2019 2018 Net sales $ 199,918 $ 176,387 $ 530,836 $ 451,687 Net income 22,203 21,285 53,223 18,853 Net income attributable to Malibu Boats, Inc. 21,099 19,838 50,430 16,066 Basic earnings per share $ 1.01 $ 0.97 $ 2.42 $ 0.80 Diluted earnings per share $ 1.01 $ 0.96 $ 2.41 $ 0.80 Cobalt On July 6, 2017, the Company completed its acquisition of Cobalt. T he aggregate purchase price for the transaction was $130,525 , consisting of $129,525 funded with cash and borrowings under the Company's credit agreement and $1,000 in equity equal to 39,262 shares of the Company's Class A Common Stock based on the closing stock price of $25.47 per share on June 27, 2017. The aggregate purchase price was subject to certain adjustments, including customary adjustments for the amount of working capital in the business at the closing date and subject to adjustment for any judgment or settlement in connection with a pending litigation matter between Cobalt and Sea Ray Boats, Inc. and Brunswick Corporation. William Paxson St. Clair, Jr., a former owner of Cobalt, was appointed as a director to the Company's Board of Directors and as President of Cobalt. The Company accounted for the transaction in accordance with ASC 805, Business Combinations . The total consideration given to the former members of Cobalt has been allocated to the assets acquired and liabilities assumed based on estimates of fair value as of the date of the acquisition. The measurements of fair value were determined based upon estimates utilizing the assistance of third party valuation specialists. The following table summarizes the purchase price allocation based on the estimated fair values of the assets acquired and liabilities of Cobalt assumed at the acquisition date: Consideration: Cash consideration paid $ 129,525 Equity consideration paid 1,000 Fair value of total consideration transferred $ 130,525 Recognized amounts of identifiable assets acquired and (liabilities assumed), at fair value: Cash $ 3,973 Accounts receivable 2,329 Inventories 14,343 Other current assets 363 Property, plant and equipment 12,934 Identifiable intangible assets 89,900 Current liabilities (13,108 ) Fair value of assets acquired and liabilities assumed 110,734 Goodwill 19,791 Total purchase price $ 130,525 The fair value estimates for the Company's identifiable intangible assets acquired as part of the acquisition are as follows: Estimates of Fair Value Estimated Useful Life (in years) Definite-lived intangibles: Dealer relationships $ 56,300 20 Patent 2,600 15 Total definite-lived intangibles 58,900 Indefinite-lived intangible: Trade name 31,000 Total intangible assets $ 89,900 The value allocated to inventories reflects the estimated fair value of the acquired inventory based on the expected sales price of the inventory, less an estimated cost to complete and a reasonable profit margin.

The estimate of fair value assigned to this asset was determined using the income approach, which requires an estimate or forecast of the expected future cash flows from the dealer relationships through the application of the multi-period excess earnings approach. The estimated remaining useful life of dealer relationships is approximately twenty years. Patent - The value associated with the patented technology was based on financial projections and the patent's estimated remaining legal life of approximately fifteen years using a variation of the income approach called the royalty savings method. Trade Name - The value attributed to Cobalt's trade name was determined using a variation of the income approach called the relief from royalty method, which requires an estimate or forecast of the expected future cash flows. The trade name has an indefinite life. The fair value of the definite-lived intangible assets are being amortized using the straight-line method to general and administrative expenses over their estimated useful lives. Indefinite-lived intangible assets are not amortized, but instead are evaluated for potential impairment on an annual basis in accordance with the provisions of ASC Topic 350, Intangibles—Goodwill and Other . The weighted average useful life of identifiable definite-lived intangible assets acquired was 19.8 years. Goodwill of $19,791 arising from the acquisition consists of expected synergies and cost savings as well as intangible assets that do not qualify for separate recognition.

Product Warranties Disclosures [Abstract]
Product Warranties	Product Warranties Effective for model year 2016, the Company began providing a limited warranty for a period up to five years for both Malibu and Axis brand boats. For model years prior to 2016, the Company provided a limited warranty for a period of up to three years and two years for its Malibu and Axis brands, respectively. For Cobalt boats, the Company provides a structural warranty of up to ten years which covers the hull, deck joints, bulkheads, floor, transom, stringers, and motor mount. In addition, the Company provides a five year bow-to-stern warranty on all components manufactured or purchased (excluding hull and deck structural components), including canvas and upholstery. For Pursuit boats, the Company provides a structural warranty of up to five years which covers structural defects in materials and workmanship on the deck and hull. Gelcoat is covered up to three years for Cobalt and one year for Malibu and Axis. In each of our brands, some materials, components or parts of the boat that are not covered by our limited product warranties are separately warranted by their manufacturers or suppliers. These other warranties include warranties covering engines and other components. The Company’s standard warranties require the Company or its dealers to repair or replace defective products during such warranty period at no cost to the consumer. The Company estimates the costs that may be incurred under its limited warranty and records a liability for such costs at the time the product revenue is recognized. Factors that affect the Company’s warranty liability include the number of units sold, historical and anticipated rates of warranty claims and cost per claim. The Company assesses the adequacy of its recorded warranty liabilities by brand on a quarterly basis and adjusts the amounts as necessary. The Company utilizes historical claims trends and analytical tools to assist in determining the appropriate warranty liability. Changes in the Company’s product warranty liability, which is included in accrued expenses on the unaudited condensed consolidated balance sheets, were as follows: Three Months Ended March 31, Nine Months Ended March 31, 2019 2018 2019 2018 Beginning balance $ 20,943 $ 15,517 $ 17,217 $ 10,050 Add: Warranty expense 2,918 2,927 8,941 7,652 Additions for acquisitions — — 1,872 4,404 Less: Warranty claims paid (1,776 ) (1,586 ) (5,945 ) (5,248 ) Ending balance $ 22,085 $ 16,858 $ 22,085 $ 16,858

On June 28, 2017, Malibu Boats, LLC as the borrower ("Boats LLC"), entered into the Second Amended and Restated Credit Agreement with SunTrust Bank, as the administrative agent, swingline lender and issuing bank, to refinance the prior credit facility and to provide funds for the purchase of Cobalt. It provided Boats LLC with a term loan facility in an aggregate principal amount of $160,000 ( $55,000 of which was drawn on June 28, 2017 to refinance our previous credit facility and $105,000 of which was drawn on July 6, 2017 to fund the payment of the purchase price for the Cobalt acquisition and to pay certain fees and expenses related to entering into the Credit Agreement and a revolving credit facility of up to $35,000 . On August 17, 2017, Boats LLC made a voluntary principal payment on the term loans in the amount of $50,000 with a portion of the net proceeds from the Company’s equity offering completed on August 14, 2017. On August 21, 2018, in connection with the acquisition of Pursuit, Boats LLC entered into the First Incremental Facility Amendment and First Amendment to the Second Amended and Restated Credit Agreement dated as of June 28, 2017 (as amended, the “Credit Agreement”). The amendment increased the amount available under the revolving credit facility by $50,000 (the “Incremental Revolving Commitment”) from $35,000 to $85,000 . Each of the term loans and the revolving credit facility are scheduled to mature on July 1, 2022. In connection with the completion of the acquisition of Pursuit, the Company borrowed $50,000 under its revolving credit facility on October 15, 2018. Borrowings under the Credit Agreement bear interest at a rate equal to either, at Boats LLC's option, (i) the highest of the prime rate, the Federal Funds Rate plus 0.5% , or one-month LIBOR plus 1% (the “Base Rate”) or (ii) LIBOR, in each case plus an applicable margin ranging from 1.75% to 3.00% with respect to LIBOR borrowings and 0.75% to 2.00% with respect to Base Rate borrowings. The applicable margin will be based upon the consolidated leverage ratio of the LLC and its subsidiaries calculated on a consolidated basis. Boats LLC is required to pay a commitment fee for the unused portion of the revolving credit facility which ranges from 0.25% to 0.50% per annum, depending on the LLC’s and its subsidiaries’ consolidated leverage ratio. Boats LLC was also required to pay a ticking fee at a rate of 0.30% per annum on the $50,000 Incremental Revolving Commitment from August 21, 2018 until the date that the conditions for the lenders to provide the Incremental Revolving Commitment were met, which occurred on October 15, 2018, the closing date of the Company's purchase of assets of Pursuit. The Company is not a party to the Credit Agreement, and the obligations of Boats LLC under the Credit Agreement are guaranteed by the LLC, and, subject to certain exceptions, the present and future domestic subsidiaries of Boats LLC, and all such obligations are secured by substantially all of the assets of the LLC, Boats LLC and such subsidiary guarantors pursuant to the Second Amended and Restated Security Agreement, by and among Boats LLC, the LLC, the subsidiary guarantors, and SunTrust Bank, as administrative agent, dated as of June 28, 2017, and other collateral documents. The weighted average interest rate on the term loan was 4.3% for the nine months ended March 31, 2019 . The Credit Agreement permits prepayment of the term loan facilities without penalty. The $55,000 term loan is subject to quarterly installments of approximately $700 per quarter until March 31, 2019, then approximately $1,000 per quarter until June 30, 2021, and approximately $1,400 per quarter through March 31, 2021. The $105,000 term loan is subject to quarterly installments of approximately $1,300 per quarter until March 31, 2019, then approximately $2,000 per quarter until June 30, 2021, and approximately $2,600 per quarter through March 31, 2022. The Company used proceeds from an offering on August 14, 2017 to repay $50,000 on its term loans under the Credit Agreement and exercised its option to apply the prepayment to principal installments through December 31, 2021, and a portion of principal installments due on March 31, 2022. Accordingly, no principal payments are required under the Credit Agreement until March 31, 2022, and as such, all borrowings as of June 30, 2018 and March 31, 2019, are reflected as noncurrent. The $50,000 repayment resulted in a write-off of deferred financing costs of $829 which was included in amortization expense on the condensed consolidated statement of operations and comprehensive income. The balance of both term loans is due on the scheduled maturity date of July 1, 2022. The Credit Agreement is also subject to prepayments from the net cash proceeds received by Boats LLC or any guarantors from certain asset sales and recovery events, subject to certain reinvestment rights, and from excess cash flow, subject to the terms and conditions of the Credit Agreement. The Credit Agreement contains certain customary representations and warranties, and notice requirements for the occurrence of specific events such as the occurrence of any event of default, or pending or threatened litigation. The Credit Agreement also requires compliance with certain customary financial covenants, including a minimum ratio of EBITDA to fixed charges and a maximum ratio of total debt to EBITDA. The Credit Agreement contains certain restrictive covenants, which, among other things, place limits on certain activities of the loan parties under the Credit Agreement, such as the incurrence of additional indebtedness and additional liens on property and limit the future payment of dividends or distributions. For example, the Credit Agreement generally prohibits the LLC, Boats LLC and the subsidiary guarantors from paying dividends or making distributions, including to the Company. The credit facility permits, however, (i) distributions based on a member’s allocated taxable income, (ii) distributions to fund payments that are required under the LLC’s tax receivable agreement, (iii) purchase of stock or stock options of the LLC from former officers, directors or employees of loan parties or payments pursuant to stock option and other benefit plans up to $2,000 in any fiscal year, and (iv) share repurchase payments up to $20,000 in any fiscal year subject to one-year carry forward and compliance with other financial covenants. In addition, the LLC may make dividends and distributions of up to $6,000 in any fiscal year, subject to compliance with other financial covenants. In connection with entering into the Credit Agreement, the Company capitalized $2,074 in deferred financing costs during fiscal 2018. These costs, in addition to the unamortized balance related to costs associated with the Company's previous credit facility of $671 , are being amortized over the term of the Credit Agreement into interest expense using the effective interest method and presented as a direct offset to the total debt outstanding as of March 31, 2019 and June 30, 2018. Covenant Compliance As of March 31, 2019 , the Company was in compliance with the covenants contained in the Credit Agreement. Interest Rate Swap On July 1, 2015, the Company entered into a five year floating to fixed interest rate swap with an effective start date of July 1, 2015. The swap is based on a one-month LIBOR rate versus a 1.52% fixed rate on a notional value of $39,250 , which was equal to 50% of the outstanding balance of the term loan at the time of the swap arrangement. Under ASC Topic 815, Derivatives and Hedging, all derivative instruments are recorded on the unaudited condensed consolidated balance sheets at fair value as either short term or long term assets or liabilities based on their anticipated settlement date. Refer to Fair Value Measurements in Note 12. The Company has elected not to designate its interest rate swap as a hedge for accounting purposes; therefore, changes in the fair value of the derivative instrument are being recognized in earnings in the Company's unaudited condensed consolidated statements of operations and comprehensive income. For the three months ended March 31, 2019 and 2018 the Company recorded a loss of $93 and a gain of $138 , respectively, and for the the nine months ended March 31, 2019 and 2018 , the Company recorded a loss of $225 and a gain of $341 , respectively, for the change in fair value of the interest rate swap, which is included in interest expense in the unaudited condensed consolidated statements of operations and comprehensive income.

Tax Receivable Agreement Liabil

Tax Receivable Agreement Liability	9 Months Ended

Tax Receivable Agreement [Abstract]
Tax Receivable Agreement Liability	Tax Receivable Agreement Liability The Company has a tax receivable agreement with the pre-IPO owners of the LLC that provides for payment by the Company to the pre-IPO owners (or their permitted assignees) of 85 % of the amount of the benefits, if any, that the Company is deemed to realize as a result of (i) increases in tax basis and (ii) certain other tax benefits related to the Company entering into the tax receivable agreement, including those attributable to payments under the tax receivable agreement. These contractual payment obligations are obligations of the Company and not of the LLC. The Company's tax receivable agreement liability was determined on an undiscounted basis in accordance with ASC 450, Contingencies , since the contractual payment obligations were deemed to be probable and reasonably estimable. The tax receivable agreement further provides that, upon certain mergers, asset sales or other forms of business combinations or other changes of control, the Company (or its successor) would owe to the pre-IPO owners of the LLC a lump-sum payment equal to the present value of all forecasted future payments that would have otherwise been made under the tax receivable agreement that would be based on certain assumptions, including a deemed exchange of LLC Units and that the Company would have sufficient taxable income to fully utilize the deductions arising from the increased tax basis and other tax benefits related to entering into the tax receivable agreement. The Company also is entitled to terminate the tax receivable agreement, which, if terminated, would obligate the Company to make early termination payments to the pre-IPO owners of the LLC. In addition, a pre-IPO owner may elect to unilaterally terminate the tax receivable agreement with respect to such pre-IPO owner, which would obligate the Company to pay to such existing owner certain payments for tax benefits received through the taxable year of the election. For purposes of the tax receivable agreement, the benefit deemed realized by the Company will be computed by comparing the actual income tax liability of the Company (calculated with certain assumptions) to the amount of such taxes that the Company would have been required to pay had there been no increase to the tax basis of the assets of the LLC as a result of the purchases or exchanges, and had the Company not entered into the tax receivable agreement. The following table reflects the changes to the Company's tax receivable agreement liability: As of March 31, 2019 As of June 30, 2018 Payable pursuant to tax receivable agreement $ 55,046 $ 82,291 Additions (reductions) to tax receivable agreement: Exchange of LLC Units for Class A Common Stock 2,675 1,685 Adjustment for change in estimated tax rate (707 ) (24,637 ) Payments under tax receivable agreement — (4,293 ) 57,014 55,046 Less current portion under tax receivable agreement (3,932 ) (3,932 ) Payable pursuant to tax receivable agreement, less current portion $ 53,082 $ 51,114 When estimating the expected tax rate to use in order to determine the tax benefit expected to be recognized from the Company’s increased tax basis as a result of exchanges of LLC Units by the pre-IPO owners of the LLC, the Company continuously monitors changes in its overall tax posture, including changes resulting from new legislation and changes as a result of new jurisdictions in which the Company is subject to tax. During the second quarter of fiscal 2018, the U.S. Congress enacted tax legislation called the Tax Cuts and Jobs Act of 2017 ("the Tax Act") on December 22, 2017, which, among other provisions, lowered the Company's U.S. corporate tax rate from 35% to 21% , effective January 1, 2018. The Tax Act lowered the estimated tax rate used to compute the Company's future tax obligations and, in turn, reduced the future tax benefit expected to be realized by the Company related to increased tax basis from previous sales and exchanges of LLC Units by pre-IPO owners of the LLC. The change in the underlying tax-rate assumptions used to estimate the tax receivable agreement liability, resulted in a decrease in the tax receivable agreement liability of $30,317 during the second quarter of fiscal 2018. Also, during the first quarter of fiscal 2018, the Company acquired Cobalt, which expanded the Company's footprint into new state tax jurisdictions. This change in the Company's state tax posture increased the estimated tax rate used in computing the Company's future tax obligations and, in turn, increased the future tax benefit expected to be realized by the Company related to increased tax basis from previous sales and exchanges of LLC Units by pre-IPO owners of the LLC. The change in the underlying tax-rate assumptions used to estimate the tax receivable agreement liability resulted in an increase in the tax receivable agreement liability of $6,047 during the first quarter of fiscal 2018. These amounts are included in other (income) expense, net in the accompanying unaudited condensed consolidated statements of operations and comprehensive income. Additionally, during the second quarter of fiscal 2019, the Company analyzed the impact of the Pursuit acquisition on its state footprint and determined that there was an immaterial change to the estimated tax rate used in computing the Company's future tax obligations. As of March 31, 2019 and June 30, 2018, the Company had deferred tax assets of $110,451 and $107,293 , respectively, associated with basis differences in assets upon acquiring an interest in Malibu Boats Holdings, LLC and pursuant to making an election under Section 754 of the Internal Revenue Code of 1986 (the "Internal Revenue Code"), as amended. The aggregate tax receivable agreement liability represents 85 % of the tax benefits that the Company expects to receive in connection with the Section 754 election.

Fair Value Measurements	9 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements In determining the fair value of certain assets and liabilities, the Company employs a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. As defined in ASC Topic 820, Fair Value Measurements and Disclosures , fair value is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (i.e., the exit price). Financial assets and financial liabilities recorded on the unaudited condensed consolidated balance sheets at fair value are categorized based on the reliability of inputs to the valuation techniques as follows: • Level 1—Financial assets and financial liabilities whose values are based on unadjusted quoted prices in active markets for identical assets. • Level 2—Financial assets and financial liabilities whose values are based on quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in non-active markets; or valuation models whose inputs are observable, directly or indirectly, for substantially the full term of the asset or liability. • Level 3—Financial assets and financial liabilities whose values are based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement. These inputs reflect the Company’s estimates of the assumptions that market participants would use in valuing the financial assets and financial liabilities. The hierarchy gives the highest priority to Level 1 inputs and the lowest priority to Level 3 inputs. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy within which the fair value measurement in its entirety falls has been determined based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. Assets and liabilities that had recurring fair value measurements were as follows: Fair Value Measurements at Reporting Date Using Total Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) As of March 31, 2019: Assets Interest rate swap not designated as cash flow hedge $ 193 $ — $ 193 $ — Total assets at fair value $ 193 $ — $ 193 $ — As of June 30, 2018: Assets Interest rate swap not designated as cash flow hedge $ 418 $ — $ 418 $ — Total assets at fair value $ 418 $ — $ 418 $ — Fair value measurements for the Company’s interest rate swap are classified under Level 2 because such measurements are based on significant other observable inputs. There were no transfers of assets or liabilities between Level 1 and Level 2 as of March 31, 2019 or June 30, 2018. The Company’s nonfinancial assets and liabilities that have nonrecurring fair value measurements include property, plant and equipment, goodwill and intangibles. In assessing the need for goodwill impairment, management relies on a number of factors, including operating results, business plans, economic projections, anticipated future cash flows, transactions and marketplace data. Accordingly, these fair value measurements fall in Level 3 of the fair value hierarchy. The Company generally uses projected cash flows, discounted as necessary, to estimate the fair values of property, plant and equipment and intangibles using key inputs such as management’s projections of cash flows on a held-and-used basis (if applicable), management’s projections of cash flows upon disposition and discount rates. Accordingly, these fair value measurements fall in Level 3 of the fair value hierarchy. These assets and certain liabilities are measured at fair value on a nonrecurring basis as part of the Company’s impairment assessments and as circumstances require.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Malibu Boats, Inc. is taxed as a C corporation for U.S. income tax purposes and is therefore subject to both federal and state taxation at a corporate level. The LLC continues to operate in the United States as a partnership for U.S. federal income tax purposes. Income taxes are computed in accordance with ASC Topic 740, Income Taxes , and reflect the net tax effects of temporary differences between the financial reporting carrying amounts of assets and liabilities and the corresponding income tax amounts. The Company has deferred tax assets and liabilities and maintains valuation allowances where it is more likely than not that all or a portion of deferred tax assets will not be realized. To the extent the Company determines that it will not realize the benefit of some or all of its deferred tax assets, such deferred tax assets will be adjusted through the Company’s provision for income taxes in the period in which this determination is made. As of March 31, 2019 and June 30, 2018, the Company maintained a valuation allowance of $ 13,298 and $ 12,716 , respectively, against deferred tax assets related to state net operating losses and future amortization deductions (with respect to the Section 754 election) that are reported in the Tennessee corporate tax return without offsetting income, which is taxable at the LLC. The increase in the valuation allowance is due to the exchanges of LLC Units into Class A common stock by certain LLC Unit holders during the nine months ended March 31, 2019 . Also as of March 31, 2019 , a valuation allowance was recorded in the amount of $761 related to foreign tax credit carryforward that is not expected to be utilized in the future. On December 22, 2017, the Tax Act was enacted which, among a number of its provisions, lowered the U.S. corporate tax rate from 35% to 21% , effective January 1, 2018. The Company’s consolidated interim effective tax rate is based upon expected annual income from operations, statutory tax rates and tax laws in the various jurisdictions in which the Company operates. Significant or unusual items, including those related to the change in U.S. tax law noted above as well as other adjustments to accruals for tax uncertainties, are recognized in the quarter in which the related event occurs. On October 15, 2018, the Company completed its acquisition of Pursuit. This did not have a significant impact to the effective tax rate. For the three months ended March 31, 2019 and 2018 , the Company's effective tax rate was 24.8% and 27.1% , respectively. For the nine months ended March 31, 2019 and 2018 , the Company's effective tax rate was 23.4% and 76.2% , respectively. For the three months ended March 31, 2019 , the Company's effective tax rate exceeded the statutory federal income tax rate of 21% primarily due to the impact of U.S. state taxes and remeasurement of deferred taxes. This increase was partially offset by the benefits of the foreign derived intangible income deduction, the research and development tax credit and the impact of non-controlling interests in the LLC. For the three and nine months ended March 31, 2018 , the principal differences in the Company's effective tax rate with the blended statutory federal income tax rate of approximately 28% relates to the remeasurement of deferred taxes. Additionally, the Company's effective tax rate for the three months ended March 31, 2018 is related to impact of the non-controlling interests in the LLC, a pass-through entity for U.S. federal tax purposes, state income taxes attributable to the LLC, and the benefit of deductions under Section 199 of the Internal Revenue Code.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation	Stock-Based Compensation The Company adopted a long term incentive plan which became effective on January 1, 2014, and reserves for issuance up to 1,700,000 shares of Malibu Boats, Inc. Class A Common Stock for the Company’s employees, consultants, members of its board of directors and other independent contractors at the discretion of the compensation committee. Incentive stock awards authorized under the Incentive Plan include unrestricted shares of Class A Common Stock, stock options, stock appreciation rights, restricted stock, restricted stock units, dividend equivalent awards and performance awards. As of March 31, 2019 , 854,974 shares remain available for future issuance under the long term incentive plan. Readers should refer to Note 13 to the fiscal 2018 audited consolidated financial statements contained in the Company's Annual Report on Form 10-K for the fiscal year ended June 30, 2018, for additional information related to the Company's awards and the Incentive Plan. On August 22, 2018, the Company granted 50,000 options to certain key employees to purchase from the Company shares of Class A Common Stock at a price of $42.13 per share. The term of the options commenced on August 22, 2018 and will expire on August 21, 2024, the day before the sixth anniversary of the grant date. Under the terms of the agreements, the awards will vest ratably over four years on each anniversary of their grant date. At August 22, 2018, the fair value of the option awards was $733 and was estimated using the Black-Scholes option-pricing model with the following assumptions: risk-free rate of 2.7% , expected volatility of 38.4% , expected term of 4.25 years, and no dividends. Stock-based compensation expense attributable to the service based options is amortized on a straight-line basis over the requisite service period. Compensation costs associated with performance based option awards are recognized over the requisite service period based on probability of achievement in accordance with ASC Topic 718, Compensation—Stock Compensation . On November 1, 2018, the Company granted 35,000 restricted stock units and 48,000 restricted stock awards to key employees under the Incentive Plan. The grant date fair value of these awards was $3,474 based on a stock price of $41.85 per share on the date of grant. Under the terms of the agreements, 71% of the awards will vest ratably over four years beginning on November 6, 2019 and approximately 29% of the awards will vest in tranches based on the achievement of annual or cumulative performance targets. Compensation costs associated with performance based awards are recognized over the requisite service period based on probability of achievement in accordance with ASC Topic 718, Compensation—Stock Compensation. On January 14, 2019, the Company granted 19,973 options to certain key employees to purchase from the Company shares of Class A Common Stock at a price of $37.55 per share. The term of the options commenced on January 14, 2019 and will expire on January 13, 2025, the day before the sixth anniversary of the grant date. Under the terms of the agreements, the awards will vest ratably over four years on each anniversary of their grant date. At January 14, 2019, the fair value of the option awards was $263 and was estimated using the Black-Scholes option-pricing model with the following assumptions: risk-free rate of 2.53% , expected volatility of 39.0% , expected term of 4.25 years, and no dividends. Stock-based compensation expense attributable to the service based options is amortized on a straight-line basis over the requisite service period. Compensation costs associated with performance based option awards are recognized over the requisite service period based on probability of achievement in accordance with ASC Topic 718, Compensation—Stock Compensation . Risk-free interest rate. The risk-free rate for the expected term of the option is based on the U.S. Treasury yield curve at the date of grant. Expected term. The Company used the simplified method to estimate the expected term of stock options. The simplified method assumes that employees will exercise share options evenly between the period when the share options are vested and ending on the date when the share options would expire. Expected volatility. The Company determined expected volatility based on its historical volatility calculated using daily observations of the closing price of its publicly traded common stock. Expected dividend. The Company has not estimated any dividend yield as the Company currently does not pay a dividend and does not anticipate paying a dividend over the expected term. The following is a summary of the changes in the Company's stock options for the nine months ended March 31, 2019 : March 31, 2019 Shares Price or range per share Weighted Average Exercise Price/Share Total outstanding options at June 30, 2018 144,000 $27.24 $ 27.24 Options granted 69,973 37.55 - 42.13 40.82 Options exercised (28,500 ) (25.85) - (30.87) (26.29 ) Outstanding options at end of period 185,473 25.85 - 42.13 32.51 Exercisable at end of period 7,500 $30.87 $ 30.87 The following is a summary of the changes in non-vested restricted stock units and restricted stock awards for the nine months ended March 31, 2019 : Number of Restricted Stock Units and Restricted Stock Awards Outstanding Weighted Average Grant Date Fair Value Total Non-vested Restricted Stock Units and Restricted Stock Awards as of June 30, 2018 227,154 $ 20.84 Granted 105,952 41.66 Vested (100,217 ) (22.81 ) Forfeited (4,424 ) (25.00 ) Total Non-vested Restricted Stock Units and Restricted Stock Awards as of March 31, 2019 228,465 $ 29.56 Stock compensation expense attributable to the Company's share-based equity awards was $735 and $560 for the three months ended March 31, 2019 and 2018 , respectively, and $1,866 and $ 1,410 for the nine months ended March 31, 2019 and 2018 , respectively.

Earnings Per Share [Abstract]
Net Earnings Per Share	Net Earnings Per Share Basic net income per share of Class A Common Stock is computed by dividing net income attributable to the Company's earnings by the weighted average number of shares of Class A Common Stock outstanding during the period. The weighted average number of shares of Class A Common Stock outstanding used in computing basic net income per share includes fully vested restricted stock units awarded to directors that are entitled to participate in distributions to common shareholders through receipt of additional units of equivalent value to the dividends paid to Class A Common Stock holders. Diluted net income per share of Class A Common Stock is computed similarly to basic net income per share except the weighted average shares outstanding are increased to include additional shares from the assumed exercise of any common stock equivalents using the treasury method, if dilutive. The Company’s LLC Units and non-qualified stock options are considered common stock equivalents for this purpose. The number of additional shares of Class A Common Stock related to these common stock equivalents and stock options are calculated using the treasury stock method. Basic and diluted net income per share of Class A Common Stock has been computed as follows (in thousands, except share and per share amounts): Three Months Ended March 31, Nine Months Ended March 31, 2019 2018 2019 2018 Basic: Net income attributable to Malibu Boats, Inc. $ 21,099 $ 15,672 $ 46,654 $ 15,174 Shares used in computing basic net income per share: Weighted-average Class A Common Stock 20,710,202 20,371,072 20,621,522 19,886,970 Weighted-average participating restricted stock units convertible into Class A Common Stock 191,345 173,416 184,390 163,988 Basic weighted-average shares outstanding 20,901,547 20,544,488 20,805,912 20,050,958 Basic net income per share $ 1.01 $ 0.76 $ 2.24 $ 0.76 Diluted: Net income attributable to Malibu Boats, Inc. $ 21,099 $ 15,672 $ 46,654 $ 15,174 Shares used in computing diluted net income per share: Basic weighted-average shares outstanding 20,901,547 20,544,488 20,805,912 20,050,958 Restricted stock units granted to employees 101,271 112,522 126,239 84,106 Stock options granted to employees 5,115 — 11,397 — Diluted weighted-average shares outstanding 1 21,007,933 20,657,010 20,943,548 20,135,064 Diluted net income per share $ 1.01 $ 0.76 $ 2.23 $ 0.76 1 The Company excluded (i) 946,875 and 1,238,727 potentially dilutive shares from the calculation of diluted net income per share for the three months ended March 31, 2019 and 2018 , respectively, and (ii) 930,125 and 1,233,227 potentially dilutive shares from the calculation of diluted net income per share for the nine months ended March 31, 2019 and 2018 , respectively, as these units would have been antidilutive. The shares of Class B Common Stock do not share in the earnings or losses of Malibu Boats, Inc. and are therefore not included in the calculation. Accordingly, basic and diluted net earnings per share of Class B Common Stock has not been presented.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Repurchase Commitments In connection with its dealers’ wholesale floor plan financing of boats, the Company has entered into repurchase agreements with various lending institutions. The reserve methodology used to record an estimated expense and loss reserve in each accounting period is based upon an analysis of likely repurchases based on current field inventory and likelihood of repurchase. Subsequent to the inception of the repurchase commitment, the Company evaluates the likelihood of repurchase and adjusts the estimated loss reserve accordingly. When a potential loss reserve is recorded it is presented in accrued liabilities in the accompanying unaudited condensed consolidated balance sheet. If the Company were obligated to repurchase a significant number of units under any repurchase agreement, its business, operating results and financial condition could be adversely affected. The total amount financed under the floor financing programs with repurchase obligations was $320,897 and $163,626 as of March 31, 2019 and June 30, 2018, respectively. Repurchases and subsequent sales are recorded as a revenue transaction. The net difference between the repurchase price and the resale price is recorded against the loss reserve and presented in cost of sales in the accompanying unaudited condensed consolidated statements of operations and comprehensive income. The Company did not carry a reserve for repurchases as of March 31, 2019 and June 30, 2018. The Company has collateralized receivables financing arrangements with a third-party floor plan financing provider for European dealers. Under terms of these arrangements, the Company transfers the right to collect a trade receivable to the financing provider in exchange for cash but agrees to repurchase the receivable if the dealer defaults. Since the transfer of the receivable to the financing provider does not meet the conditions for a sale under ASC Topic 860, Transfers and Servicing , the Company continues to report the transferred trade receivable in other current assets with an offsetting balance recorded as a secured obligation in accrued expenses in the Company's unaudited condensed consolidated balance sheet. As of March 31, 2019 and June 30, 2018, the Company had financing receivables of $589 and $453 , respectively, recorded in other current assets and accrued expenses related to these arrangements. Contingencies Certain conditions may exist which could result in a loss, but which will only be resolved when future events occur. The Company, in consultation with its legal counsel, assesses such contingent liabilities, and such assessments inherently involve an exercise of judgment. If the assessment of a contingency indicates that it is probable that a loss has been incurred, the Company accrues for such contingent loss when it can be reasonably estimated. If the assessment indicates that a potentially material loss contingency is not probable but reasonably estimable, or is probable but cannot be estimated, the nature of the contingent liability, together with an estimate of the range of possible loss if determinable and material, is disclosed. If the assessment of a contingency deemed to be both probable and reasonably estimable involves a range of possible losses, the amount within the range that appears at the time to be a better estimate than any other amount within the range would be accrued. When no amount within the range is a better estimate than any other amount, the minimum amount in the range is accrued even though the minimum amount in the range is not necessarily the amount of loss that will be ultimately determined. Estimates of potential legal fees and other directly related costs associated with contingencies are not accrued but rather are expensed as incurred. Except as disclosed below under "Legal Proceedings," management does not believe there are any pending claims (asserted or unasserted) at March 31, 2019 (unaudited) or June 30, 2018 that may have a material adverse impact on the Company’s financial condition, results of operations or cash flows. Legal Proceedings On January 12, 2018, the Company filed suit against Skier’s Choice, Inc., or "Skier’s Choice," in the U.S. District Court for the Eastern District of Tennessee, seeking monetary and injunctive relief. The Company's complaint alleges Skier’s Choice’s infringement of three utility patents - U.S. Patent Nos. 9,260,161, 8,578,873, and 9,199,695 - related to wake surfing technology. Skier’s Choice denied liability arising from the causes of action alleged in the Company's complaint and filed counterclaims alleging invalidity of the asserted patents. The parties are currently engaged in discovery. The Company intends to vigorously pursue this litigation to enforce its rights in its patented technology and believes that Skier’s Choice’s counterclaims are without merit. Trial is set for October 21, 2019. On January 21, 2015, Cobalt, a wholly owned indirect subsidiary of the Company, filed a patent infringement lawsuit against the Brunswick Corporation and its subsidiary Sea Ray Boats, Inc. alleging that certain of the Sea Ray's branded boats infringed upon Cobalt's patented submersible swim step technology (U.S. Patent No. 8,375,880). On October 31, 2017, the US District Court in the Eastern District of Virginia entered an amended judgment on the jury verdict in favor of Cobalt.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited interim condensed consolidated financial statements of the Company have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim condensed financial statements and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all information and disclosures of results of operations, financial position and changes in cash flow in conformity with GAAP for complete financial statements. Such statements should be read in conjunction with the audited consolidated financial statements and notes thereto of Malibu Boats, Inc. and subsidiaries for the year ended June 30, 2018, included in the Company's Annual Report on Form 10-K. In the opinion of management, the accompanying unaudited interim condensed consolidated financial statements reflect all adjustments considered necessary to present fairly the Company’s financial position at March 31, 2019 , and the results of its operations for the three and nine month periods ended March 31, 2019 and March 31, 2018 , and its cash flows for the nine month periods ended March 31, 2019 and March 31, 2018 . Operating results for the three and nine months ended March 31, 2019 , are not necessarily indicative of the results that may be expected for the full year ending June 30, 2019 . Units and shares are presented as whole numbers while all dollar amounts are presented in thousands, unless otherwise noted.
Principles of Consolidation	Principles of Consolidation The accompanying unaudited condensed consolidated financial statements include the operations and accounts of the Company and all subsidiaries thereof. All intercompany balances and transactions have been eliminated upon consolidation.
Pursuit Acquisition	Pursuit Acquisition On October 15, 2018, our subsidiary Malibu Boats, LLC, purchased the assets of Pursuit from S2 Yachts, Inc. for a purchase price of $100,073 . Pursuit, located in Fort Pierce, Florida, is a leader in the saltwater outboard fishing boat market through its offering of 15 models of offshore, dual console and center console boats.
Recent Accounting Pronouncements	Recent Accounting Pronouncements On July 1, 2018, the Company adopted the new accounting standard, ASC Topic 606, Revenue from Contracts with Customers, and all the related amendments (“ASC 606”) and applied the provisions of the standard to all contracts using the modified retrospective method. The cumulative effect of adopting the new revenue standard was immaterial and no adjustment has been recorded to the opening balance of retained earnings. Prior year information has not been restated and continues to be reported under the accounting standards in effect for those periods. Substantially all of the Company’s revenue continues to be recognized at a point in time when the product is either shipped or received from the Company's facilities and control of the product is transferred to the customer. New controls and processes designed to meet the requirements of the standard were implemented, and the required new disclosures are presented in Note 2. The adoption of ASC Topic 606 did not have a material impact on the amounts reported in the Company's unaudited condensed consolidated financial position, results of operations or cash flows. In February 2016, the FASB issued Accounting Standards Update (ASU) 2016‑02, Leases (Topic 842) . The amendments in this update create ASC Topic 842, Leases , and supersede the requirements in ASC Topic 840, Leases . ASC Topic 842 requires lessees to recognize on the balance sheet a right‑of‑use asset, representing its right to use the underlying asset for the lease term, and a lease liability for all leases with terms greater than 12 months. The guidance also requires qualitative and quantitative disclosures designed to assess the amount, timing, and uncertainty of cash flows arising from leases. The standard requires the use of a modified retrospective transition approach, which includes a number of optional practical expedients that entities may elect to apply. In June 2018, the FASB issued ASU 2018-11, Leases (Topic 842): Targeted Improvement , which provides entities with an additional (optional) transition method to adopt the new lease standard. Under this new transition method, an entity initially applies the new leases standard at the adoption date and recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. The new leases standard is effective for fiscal years beginning after December 15, 2018. Early application is permitted. The Company is currently developing a project plan to guide the implementation of ASU 2016-02. The Company is making progress on this plan including surveying the Company’s businesses, assessing the Company’s portfolio of leases and compiling information on active leases. The Company is currently identifying and implementing appropriate changes to its policies, business processes, systems and controls to support lease accounting and disclosures under Topic 842. The Company does not expect that its results of operations or cash flows will be materially impacted by this standard. The Company expects to record right of use assets and lease liabilities on its consolidated balance sheets upon adoption of this standard, which may be material. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments . This guidance provides specific classification of how certain cash receipts and cash payments are presented in the statement of cash flows. The ASU was applied using a retrospective transition method. The adoption of this ASU on July 1, 2018 did not have a material impact on the Company's consolidated financial statements. In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business . The guidance clarifies the definition of a business that provides a two-step analysis in the determination of whether an acquisition or derecognition is a business or an asset. The update removes the evaluation of whether a market participant could replace any missing elements and provides a framework to assist entities in evaluating whether both an input and a substantive process are present. This guidance will be applied on a prospective basis for transactions that occur after the effective date. The adoption of this ASU on July 1, 2018 did not have a material impact on the Company's consolidated financial statements. There are no other new accounting pronouncements that are expected to have a significant impact on the Company's consolidated financial statements and related disclosures.
