Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies Interim Financial Statements. The unaudited interim condensed consolidated financial statements of Brunswick Corporation (Brunswick or the Company) have been prepared pursuant to Securities and Exchange Commission (SEC) rules and regulations. Therefore, certain information and disclosures normally included in financial statements and related notes prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) have been condensed or omitted. These financial statements should be read in conjunction with, and have been prepared in conformity with, the accounting principles reflected in the consolidated financial statements and related notes included in Brunswick’s 2018 Annual Report on Form 10-K for the year ended December 31, 2018 (the 2018 Form 10-K). These results include, in management's opinion, all normal and recurring adjustments necessary to present fairly Brunswick's financial position, results of operations and cash flows. Due to the seasonality of Brunswick’s businesses, the interim results are not necessarily indicative of the results that may be expected for the remainder of the year. The Company maintains its financial records on the basis of a fiscal year ending on December 31, with the fiscal quarters spanning approximately thirteen weeks. The first quarter ends on the Saturday closest to the end of the first thirteen -week period. The second and third quarters are thirteen weeks in duration and the fourth quarter is the remainder of the year. The first quarter of fiscal year 2019 ended on March 30, 2019 and the first quarter of fiscal year 2018 ended on March 31, 2018 . On March 1, 2018, the Company's Board of Directors authorized proceeding with separating its Fitness business from the Company portfolio. While the Company continues to maintain its preparedness for a spin-off of the Fitness business, there has been a strong level of buyer interest in the sales process. Should the separation take the form of a sale, the Company anticipates a sale would be announced in the second quarter of 2019. Recently Adopted Accounting Standards Recognition of Leases : In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-02, Leases, (new leasing standard), which amended the Accounting Standards Codification (ASC) to require lessees to recognize assets and liabilities on the balance sheet for all leases with terms greater than twelve months. On January 1, 2019, the Company adopted the new leasing standard and all related amendments. The Company elected the optional transition method provided by the FASB in ASU 2018-11, Leases (Topic 842): Targeted Improvements , and as a result, has not restated its condensed consolidated financial statements for prior periods presented. The Company has elected the practical expedients upon transition to retain the lease classification and initial direct costs for any leases that existed prior to adoption. The Company has also not reassessed whether any contracts entered into prior to adoption are leases. The standard did not have a material impact on the Company's Condensed Consolidated Statements of Comprehensive Income. The cumulative effect of the changes made to the Company's Consolidated Balance Sheet as of January 1, 2019 for the adoption of the new leasing standard was as follows: (in millions) Balance as of December 31, 2018 Adjustments Due to ASC 842 Balance as of January 1, 2019 Assets Operating lease assets $ — $ 101.2 $ 101.2 Current liabilities Accrued expenses 687.4 19.3 706.7 Long-term liabilities Other 195.5 (3.4 ) 192.1 Operating lease liabilities — 85.3 85.3 The Company determines if an arrangement is a lease at lease inception. Operating lease right-of-use (ROU) assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As most of the Company's lease contracts do not include an implicit rate, the Company uses its incremental borrowing rate based on information available at commencement date in determining the present value of future payments. The incremental borrowing rate is estimated to approximate the interest rate on a collateralized basis with similar terms and payments, and in economic environments where the leased asset is located. The operating lease ROU asset also includes any initial direct costs and lease payments made prior to lease commencement, and excludes lease incentives incurred. The Company's lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Operating lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. The Company has certain lease agreements that contain both lease and non-lease components, which it has elected to account for as a single lease component for all asset classes. Measurement of Goodwill Impairment : In January 2017, the FASB issued ASU 2017-04, Intangibles-Goodwill and Other (Topic 350), Simplifying the Test for Goodwill Impairment . The standard simplifies the subsequent measurement of goodwill by eliminating step two from the goodwill impairment test. Instead, goodwill impairment is measured as the difference between the fair value and the carrying value of the reporting unit. The standard also clarifies the treatment of the income tax effect of tax-deductible goodwill when measuring goodwill impairment loss. The Company early adopted this amendment on January 1, 2019. Tax Effects in Other Comprehensive Income : In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (AOCI) , which requires certain new disclosures and permits companies to reclassify the disproportionate income tax effects of the Tax Cuts and Jobs Act of 2017 on items within AOCI to retained earnings. The Company currently records its stranded tax effects in AOCI using the portfolio approach. Upon adoption, the Company elected not to reclassify stranded tax effects in AOCI to retained earnings and there was no impact on its consolidated financial statements. Hedge Accounting : In August 2017, the FASB issued ASU 2017-12, Targeted Improvements to Accounting for Hedging Activities, to simplify the application of hedge accounting and to better align an entity's risk management activities with the financial reporting of hedging relationships. The Company adopted this ASC amendment and it did not have a material impact on its consolidated financial statements.

Business Combination Disclosure [Text Block]	Acquisitions 2018 Acquisitions On August 9, 2018, the Company completed its acquisition of the Global Marine & Mobile business of Power Products Holdings, LLC (Power Products) for $909.6 million in cash, on a cash-free, debt-free basis. Brunswick used proceeds from a combination of 364-day, three-year and five-year term loans (Term Loans) totaling $800.0 million as described in the 2018 Form 10-K along with cash on hand to fund this acquisition. Power Products is a leading provider of electrical products to marine and other recreational and specialty vehicle markets. The acquisition advances Brunswick’s leadership by adding integrated electrical systems solutions to the marine market and an array of other mobile, specialty vehicle and industrial applications. Power Products is managed as part of the Marine Engine segment.

Share-Based Compensation

Share-Based Compensation	3 Months Ended

Share-based Compensation [Abstract]
Share-Based Compensation	Share-Based Compensation Under the Brunswick Corporation 2014 Stock Incentive Plan, the Company may grant stock appreciation rights (SARs), non-vested stock awards and performance awards to executives, other employees and non-employee directors from treasury shares and from authorized, but unissued, shares of common stock initially available for grant, in addition to: (i) the forfeiture of past awards; (ii) shares not issued upon the net settlement of SARs; or (iii) shares delivered to or withheld by the Company to pay the withholding taxes related to awards. As of March 30, 2019 , 4.9 million shares remained available for grant. Non-Vested Stock Awards The Company grants both stock-settled and cash-settled non-vested stock units and awards to key employees as determined by management and the Human Resources and Compensation Committee of the Board of Directors. The Company granted 0.3 million of stock awards during both the three months ended March 30, 2019 and March 31, 2018 . The Company recognizes the cost of non-vested stock units and awards on a straight-line basis over the requisite vesting period. Additionally, cash-settled non-vested stock units and awards are recorded as a liability on the balance sheet and adjusted to fair value each reporting period through stock compensation expense. During the three months ended March 30, 2019 and March 31, 2018 , the Company charged $2.6 million and $2.5 million , respectively, to compensation expense for non-vested stock awards. As of March 30, 2019 , there was $27.1 million of total unrecognized compensation cost related to non-vested share-based compensation arrangements. The Company expects this cost to be recognized over a weighted average period of 2.4 years . Performance Awards In both February of 2019 and 2018 , the Company granted 0.1 million performance shares to certain senior executives. Performance share awards are based on three performance measures: a cash flow return on investment (CFROI) measure, an operating margin (OM) measure and a total shareholder return (TSR) modifier. Performance shares are earned based on a three-year performance period commencing at the beginning of the calendar year of each grant. The performance shares earned are then subject to a TSR modifier based on the Company's stock returns measured against stock returns of a predefined comparator group over a three-year performance period. Additionally, in February 2019 and 2018 , the Company granted 24,605 and 24,490 performance shares, respectively, to certain officers and certain senior managers based on the respective measures and performance periods described above but excluding the TSR modifier. During the three months ended March 30, 2019 and March 31, 2018 , the Company recognized a charge of $0.7 million and a benefit of $0.5 million , respectively, based on projections of probable attainment of the performance measures and the projected TSR modifier used to determine the performance awards. The fair values of the senior executives' performance share award grants with a TSR modifier for grants in 2019 and 2018 were $49.64 and $61.59 , respectively, which were estimated using the Monte Carlo valuation model, and incorporated the following assumptions: 2019 2018 Risk-free interest rate 2.9 % 2.4 % Dividend yield 1.7 % 1.3 % Volatility factor 41.0 % 38.9 % Expected life of award 2.9 years 2.9 years The fair value of certain officers' and certain senior managers' performance awards granted based solely on the CFROI and OM performance factors was $47.61 and $57.19 in 2019 and 2018 , respectively, which was equal to the stock price on the date of grant in 2019 and 2018 , respectively, less the present value of expected dividend payments over the vesting period. As of March 30, 2019 , the Company had $8.4 million of total unrecognized compensation cost related to performance awards. The Company expects this cost to be recognized over a weighted average period of 1.5 years. Director Awards The Company issues stock awards to non-employee directors in accordance with the terms and conditions determined by the Nominating and Corporate Governance Committee of the Board of Directors. A portion of each director’s annual fee is paid in Brunswick common stock, the receipt of which may be deferred until a director retires from the Board of Directors. Each director may elect to have the remaining portion paid in cash, in Brunswick common stock distributed at the time of the award, or in deferred Brunswick common stock with a 20 percent premium.

Goodwill and Other Intangibles [Text Block]	Goodwill and Other Intangibles Changes in the Company's goodwill during the three months ended March 30, 2019 , by segment, are summarized below: (in millions) December 31, Impairments Adjustments March 30, Marine Engine $ 375.1 $ — $ 4.5 $ 379.6 Boat 2.2 — — 2.2 Fitness 389.8 (137.2 ) (0.3 ) 252.3 Total $ 767.1 $ (137.2 ) $ 4.2 $ 634.1 Changes in the Company's goodwill during the three months ended March 31, 2018 , by segment, are summarized below: (in millions) December 31, Impairments Adjustments March 31, Marine Engine $ 31.7 $ — $ 1.2 $ 32.9 Boat 2.2 — — 2.2 Fitness 391.4 — 1.8 393.2 Total $ 425.3 $ — $ 3.0 $ 428.3 Due to recent, significant progress made toward the planned Fitness business separation and the strong level of buyer interest in the sales process, the Company re-evaluated the fair value of the Fitness reporting unit in the first quarter of 2019. To assess fair value, the Company performed a quantitative test using a combination of the market approach and the income approach. Fair value under the market approach was informed by significant progress made on the sale process during the quarter. The income approach calculates the fair value of the reporting unit using a discounted cash flow approach utilizing a Gordon Growth model. Internally forecasted future cash flows are discounted using a weighted average cost of capital (Discount Rate) developed for each reporting unit. The Discount Rate is developed using market observable inputs, as well as considering whether or not there is a measure of risk related to the specific reporting unit’s forecasted performance. As a result of performing the fair value test, the Company determined the fair value of the Fitness reporting unit was less than its carrying value resulting in a pre-tax goodwill impairment charge of $137.2 million ( $103.0 million after tax) for the three months ended March 30, 2019. The impairment was calculated in accordance with ASU 2017-04 as discussed in Note 1 - Significant Accounting Policies in the Notes to Condensed Consolidated Financial Statements. The charge was recorded within the Company’s Fitness segment within Restructuring, exit, integration and impairment in the Condensed Consolidated Statements of Comprehensive Income. Adjustments for the three months ended March 30, 2019 mainly relate to refining purchase accounting related to the Power Products acquisition. See Note 4 – Acquisitions for further details on the Company's acquisitions. Adjustments in both periods include the effect of foreign currency translation on goodwill denominated in currencies other than the U.S. dollar. As of March 30, 2019 the Company had $137.2 million of accumulated impairment loss on Goodwill. There was no accumulated impairment loss on Goodwill as of December 31, 2018 and March 31, 2018 .

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company recognized an income tax benefit of $(11.4) million and an income tax provision of $27.2 million for the three months ended March 30, 2019 and March 31, 2018 , respectively, which included a net benefit of $(0.6) million and a net charge of $6.7 million , respectively. The net benefit of $(0.6) million related to certain special tax items. The net charge of $6.7 million was due primarily to updates related to 2017 tax reform. The effective tax rate, which is calculated as the income tax provision (benefit) as a percentage of earnings (loss) before income taxes, for the three months ended March 30, 2019 and March 31, 2018 was 23.9 percent and 27.2 percent , respectively. No deferred income taxes have been provided as of March 30, 2019 , December 31, 2018 or March 31, 2018 on the applicable undistributed earnings of the non-U.S. subsidiaries where the indefinite reinvestment assertion has been applied. If at some future date these earnings cease to be indefinitely reinvested and are repatriated, the Company may be subject to additional U.S. income taxes and foreign withholding taxes on such amounts. The Company continues to provide deferred taxes, as required, on the undistributed net earnings of foreign subsidiaries and unconsolidated affiliates that are not deemed to be indefinitely reinvested in operations outside the United States. As of March 30, 2019 , December 31, 2018 and March 31, 2018 , the Company had $2.7 million , $2.3 million and $2.8 million of gross unrecognized tax benefits, including interest, respectively. The Company believes it is reasonably possible that the total amount of gross unrecognized tax benefits as of March 30, 2019 could decrease by approximately $1.0 million in the next 12 months due to settlements with taxing authorities or lapses in the applicable statute of limitations. Due to the various jurisdictions in which the Company files tax returns and the uncertainty regarding the timing of the settlement of tax audits, it is possible that there could be significant changes in the amount of unrecognized tax benefits in 2019 , but the amount cannot be estimated at this time. The Company is regularly audited by federal, state and foreign tax authorities. The Internal Revenue Service (IRS) has completed its field examination and has issued its Revenue Agents Report through the 2014 tax year and all open issues have been resolved. The Company is currently open to tax examinations by the IRS for the 2014 through 2017 tax years. Primarily as a result of filing amended returns, which were generated by the closing of federal income tax audits, the Company is still open to state and local tax audits in major tax jurisdictions dating back to the 2012 taxable year. The Company is no longer subject to income tax examinations by any major foreign tax jurisdiction for years prior to 2013.

Accounting Policies [Abstract]
Basis of Accounting	Interim Financial Statements. The unaudited interim condensed consolidated financial statements of Brunswick Corporation (Brunswick or the Company) have been prepared pursuant to Securities and Exchange Commission (SEC) rules and regulations. Therefore, certain information and disclosures normally included in financial statements and related notes prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) have been condensed or omitted.
Fiscal Period Policy	The Company maintains its financial records on the basis of a fiscal year ending on December 31, with the fiscal quarters spanning approximately thirteen weeks. The first quarter ends on the Saturday closest to the end of the first thirteen -week period. The second and third quarters are thirteen weeks in duration and the fourth quarter is the remainder of the year. The first quarter of fiscal year 2019 ended on March 30, 2019 and the first quarter of fiscal year 2018 ended on March 31, 2018 .
Recent Accounting Pronouncements	Recently Adopted Accounting Standards Recognition of Leases : In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-02, Leases, (new leasing standard), which amended the Accounting Standards Codification (ASC) to require lessees to recognize assets and liabilities on the balance sheet for all leases with terms greater than twelve months. On January 1, 2019, the Company adopted the new leasing standard and all related amendments. The Company elected the optional transition method provided by the FASB in ASU 2018-11, Leases (Topic 842): Targeted Improvements , and as a result, has not restated its condensed consolidated financial statements for prior periods presented. The Company has elected the practical expedients upon transition to retain the lease classification and initial direct costs for any leases that existed prior to adoption. The Company has also not reassessed whether any contracts entered into prior to adoption are leases. The standard did not have a material impact on the Company's Condensed Consolidated Statements of Comprehensive Income. The cumulative effect of the changes made to the Company's Consolidated Balance Sheet as of January 1, 2019 for the adoption of the new leasing standard was as follows: (in millions) Balance as of December 31, 2018 Adjustments Due to ASC 842 Balance as of January 1, 2019 Assets Operating lease assets $ — $ 101.2 $ 101.2 Current liabilities Accrued expenses 687.4 19.3 706.7 Long-term liabilities Other 195.5 (3.4 ) 192.1 Operating lease liabilities — 85.3 85.3 The Company determines if an arrangement is a lease at lease inception. Operating lease right-of-use (ROU) assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As most of the Company's lease contracts do not include an implicit rate, the Company uses its incremental borrowing rate based on information available at commencement date in determining the present value of future payments. The incremental borrowing rate is estimated to approximate the interest rate on a collateralized basis with similar terms and payments, and in economic environments where the leased asset is located. The operating lease ROU asset also includes any initial direct costs and lease payments made prior to lease commencement, and excludes lease incentives incurred. The Company's lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Operating lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. The Company has certain lease agreements that contain both lease and non-lease components, which it has elected to account for as a single lease component for all asset classes. Measurement of Goodwill Impairment : In January 2017, the FASB issued ASU 2017-04, Intangibles-Goodwill and Other (Topic 350), Simplifying the Test for Goodwill Impairment . The standard simplifies the subsequent measurement of goodwill by eliminating step two from the goodwill impairment test. Instead, goodwill impairment is measured as the difference between the fair value and the carrying value of the reporting unit. The standard also clarifies the treatment of the income tax effect of tax-deductible goodwill when measuring goodwill impairment loss. The Company early adopted this amendment on January 1, 2019. Tax Effects in Other Comprehensive Income : In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (AOCI) , which requires certain new disclosures and permits companies to reclassify the disproportionate income tax effects of the Tax Cuts and Jobs Act of 2017 on items within AOCI to retained earnings. The Company currently records its stranded tax effects in AOCI using the portfolio approach. Upon adoption, the Company elected not to reclassify stranded tax effects in AOCI to retained earnings and there was no impact on its consolidated financial statements. Hedge Accounting : In August 2017, the FASB issued ASU 2017-12, Targeted Improvements to Accounting for Hedging Activities, to simplify the application of hedge accounting and to better align an entity's risk management activities with the financial reporting of hedging relationships. The Company adopted this ASC amendment and it did not have a material impact on its consolidated financial statements.
