Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies Basis of Presentation. Effective January 1, 2020, the Company changed its management reporting and updated its reportable segments to Propulsion, Parts and Accessories (P&A) and Boat (inclusive of Business Acceleration) to align with its strategy. As a result of this change, the Company has recast all segment information for all prior periods presented. Refer to Note 11 – Segment Data for further information on the Company's reportable segments. 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 2019 Annual Report on Form 10-K for the year ended December 31, 2019 (the 2019 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 second quarter of fiscal year 2020 ended on June 27, 2020 and the second quarter of fiscal year 2019 ended on June 29, 2019 . On June 27, 2019, the Company completed the sale of its Fitness business. The Company determined that the sale of its Fitness business represented a strategic shift that had a major effect on the Company's operations and financial results. Refer to Note 3 – Discontinued Operations for further information. Recently Adopted Accounting Standards Current Expected Credit Loss : In June 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-13, Measurement of Credit Losses on Financial Instruments, which updated the Accounting Standards Codification (ASC) to add an impairment model that is based on expected losses rather than incurred losses. On January 1, 2020, the Company adopted this standard and the adoption did not have an impact on the condensed consolidated financial statements.

Share-based Payment Arrangement, Noncash Expense [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 units and 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 stock units and 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 stock units and awards. As of June 27, 2020 , 4.8 million shares remained available for grant. Share grant amounts, fair values, and fair value assumptions reflect all outstanding stock units and awards for both continuing and discontinued operations. Non-Vested Stock Units The Company grants both stock-settled and cash-settled non-vested stock units to key employees as determined by management and the Human Resources and Compensation Committee of the Board of Directors. The Company granted 0.1 million stock units during both the three months ended June 27, 2020 and June 29, 2019 , respectively. The Company granted 0.3 million and 0.4 million of stock units during the six months ended June 27, 2020 and June 29, 2019 , respectively. The Company recognizes the cost of non-vested stock units on a straight-line basis over the requisite vesting period. Additionally, cash-settled non-vested stock units 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 and six months ended June 27, 2020 , the Company charged $4.4 million and $6.4 million , respectively, and charged $1.6 million and $3.7 million during the three months and six months ended June 29, 2019 , respectively to compensation expense for non-vested stock units. As of June 27, 2020 , there was $19.4 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 1.6 years . Performance Awards In both February of 2020 and 2019 , 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 2020 and 2019 , the Company granted 26,750 and 24,605 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 and six months ended June 27, 2020 , the Company recognized a charge of $4.5 million and $2.4 million , respectively, and charged $2.6 million and $3.3 million for the three months and six months ended June 29, 2019 , respectively, to compensation expense 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 2020 and 2019 were $64.72 and $49.64 , respectively, which were estimated using the Monte Carlo valuation model, and incorporated the following assumptions: 2020 2019 Risk-free interest rate 1.4 % 2.9 % Dividend yield 1.5 % 1.7 % Volatility factor 46.6 % 41.0 % 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 $61.91 and $47.61 in 2020 and 2019 , respectively, which was equal to the stock price on the date of grant in 2020 and 2019 , respectively, less the present value of expected dividend payments over the vesting period. As of June 27, 2020 , the Company had $6.1 million of total unrecognized compensation cost related to performance awards. The Company expects this cost to be recognized over a weighted average period of 1.3 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.

The Company considered both quantitative and qualitative factors in its analysis and determined the fair values of its intangible assets were not “more-likely-than-not” lower than their carrying values. As such, the Company did not record an impairment charge during the three months ended March 28, 2020. As business performance and marine demand exceeded expectations during the three months ended June 27, 2020 , and no further triggering events were identified, the Company did not perform an additional interim impairment test in the second quarter. The Company will continue to monitor the impacts of COVID-19 and assess the need for further testing going forward.

Segment Reporting [Abstract]
Segment Data	Segment Data Change in Reportable Segments Effective January 1, 2020, the Company changed its management reporting and updated its reportable segments to Propulsion, Parts and Accessories and Boat (inclusive of Business Acceleration) to align with its strategy. Concurrent with this change, the Company has changed its measurement of segment profit and loss due to a decision to streamline internal and external reporting practices relating to marine engines sold from the Propulsion segment to the Boat segment. This change in presentation, which is not the result of a change in business practice, more closely follows current market dynamics, and provides improved comparability with other boat companies. Reportable Segments The Company's segments are defined by management's reporting structure and operating activities. The Company's reportable segments are the following: Propulsion . The Propulsion segment manufactures and markets a full range of outboard, sterndrive, and inboard engines, as well as propulsion-related controls, propellers, and rigging parts and accessories. These products are principally sold directly to boat builders, including Brunswick’s Boat segment, and through marine retail dealers worldwide. The Propulsion segment primarily markets under the Mercury, Mercury MerCruiser, Mariner, Mercury Racing, and Mercury Diesel brands. The segment's engine manufacturing plants are located mainly in the United States and China, along with a joint venture in Japan, with sales mainly to markets in the Americas, Europe and Asia-Pacific. Parts and Accessories. The Parts and Accessories (P&A) segment consists of the Engine Parts and Accessories and the Advanced Systems Group operating segments, which are aggregated and presented as a single reportable segment. The P&A segment manufactures, markets, and supplies parts and accessories for both marine and non-marine markets. These products are designed for and sold mostly to aftermarket retailers, distributors, and distribution businesses, as well as original equipment manufacturers (including Brunswick brands). Branded parts and accessories include consumables, such as engine oils and lubricants, and are sold under the Mercury, Mercury Precision Parts, Quicksilver, and Seachoice brands. The P&A segment also consists of distribution businesses such as Land 'N' Sea, Kellogg Marine Supply, Lankhorst Taselaar, BLA, and Payne's Marine Group, which distribute third-party and Company products. These businesses are leading distributors of marine parts and accessories throughout North America, Europe, and Asia-Pacific. The P&A segment also includes the collection of brands acquired with Power Products in 2018 and certain other businesses operating under the Ancor, Attwood, BEP, Blue Sea Systems, CZone, Del City, Garelick, Lenco Marine, Marinco, Mastervolt, MotorGuide, ParkPower, Progressive Industries, ProMariner, and Whale brand names. Products include marine electronics and control systems, instruments, trolling motors, fuel systems, electrical systems, as well as specialty vehicle, mobile, and transportation aftermarket products. The P&A segment's manufacturing and distribution facilities are primarily located in North America and Europe. Boat. The Boat segment designs, manufactures and markets the following boat brands and products: Sea Ray sport boats and cruisers; Bayliner sport cruisers, runabouts, and Heyday wake boats; Boston Whaler fiberglass offshore boats; Lund fiberglass fishing boats; Crestliner, Cypress Cay, Harris, Lowe, Lund, and Princecraft aluminum fishing, utility, pontoon boats, and deck boats; and Thunder Jet heavy-gauge aluminum boats. The Boat Group procures substantially all of its outboard engines, gasoline sterndrive engines, and gasoline inboard engines from Brunswick's Propulsion segment. The Boat Group also includes Brunswick boat brands based in Europe and Asia-Pacific, which include Quicksilver, Uttern, and Rayglass (including Protector and Legend). The Boat segment's products are manufactured mainly in the United States, Europe and Mexico and sold through a global network of dealer and distributor locations, primarily in North America and Europe. The Boat segment also includes the Business Acceleration business, which through innovative service models, shared access solutions, including the Freedom Boat Club business acquired in 2019, dealer services and emerging technology, aims to provide exceptional experiences to attract a wide range of customers to the marine industry and shape the future of boating. The Company evaluates performance based on segment operating earnings. Segment operating earnings do not include the expenses of corporate administration, pension costs and pension settlement charges, impairments or gains on the sale of equity investments, earnings from unconsolidated affiliates, other expenses and income of a non-operating nature, transaction financing charges, interest expense, and income or provisions or benefits for income taxes. Corporate/Other results include items such as corporate staff and administrative costs, investments in technology solutions, business development and other growth-related expenses, including IT enhancements. Corporate/Other total assets consist of mainly cash, cash equivalents and investments in marketable securities, restricted cash, income tax balances and investments in unconsolidated affiliates. Segment eliminations adjust for sales between the Company's reportable segments and primarily relate to the sale of engines and parts and accessories to various boat brands, which are consummated at established arm’s length transfer prices as the intersegment pricing for these engines and parts and accessories are based upon and consistent with selling prices to third party customers. The following table sets forth net sales and operating earnings (loss) for each of the Company's reportable segments for the three months and six months ended June 27, 2020 and June 29, 2019 : Net Sales Operating Earnings (Loss) Three Months Ended Six Months Ended Three Months Ended Six Months Ended (in millions) June 27, June 29, June 27, June 29, June 27, June 29, June 27, June 29, Propulsion $ 395.4 $ 461.5 $ 844.0 $ 913.9 $ 47.7 $ 71.0 $ 109.0 $ 130.9 Parts and Accessories 386.5 410.0 688.1 723.6 80.1 88.2 126.3 136.0 Boat 249.9 366.6 541.4 739.9 2.0 25.8 7.1 52.8 Corporate/Other — — — — (22.8 ) (22.3 ) (32.2 ) (42.9 ) Segment Eliminations (44.0 ) (74.6 ) (120.2 ) (163.2 ) — — — — Total $ 987.8 $ 1,163.5 $ 1,953.3 $ 2,214.2 $ 107.0 $ 162.7 $ 210.2 $ 276.8 The following table sets forth total assets of each of the Company's reportable segments: Total Assets (in millions) June 27, December 31, June 29, Propulsion $ 974.2 $ 1,002.8 $ 1,007.3 Parts and Accessories 1,534.9 1,519.0 1,603.3 Boat (A) 463.7 473.0 477.2 Corporate/Other 766.3 569.6 953.0 Total $ 3,739.1 $ 3,564.4 $ 4,040.8 (A) As of June 27, 2020 , December 31, 2019 and June 29, 2019 , the Company had $3.0 million of assets classified as held for sale which were not related to discontinued operations.

Income Taxes	Income Taxes The Company recognized an income tax provision for the three months and six months ended June 27, 2020 of $17.6 million and $36.0 million , respectively, which included a net charge of $0.4 million and $0.1 million , respectively. These charges primarily related to a change in the valuation allowance. The Company recognized an income tax provision for the three months and six months ended June 29, 2019 of $31.7 million and $50.5 million , respectively, which included a net charge of $1.8 million and $0.1 million , respectively. The net charge of $1.8 million primarily related to an increase in the valuation allowance and the net charge of $0.1 million was related to the aforementioned valuation allowance increase and other various special tax items. The effective tax rate, which is calculated as the income tax provision as a percentage of earnings before income taxes, for the three months and six months ended June 27, 2020 , was 19.8 percent and 20.2 percent , respectively. The effective tax rate for the three months and six months ended June 29, 2019 was 22.0 percent and 21.1 percent , respectively. No deferred income taxes have been provided as of June 27, 2020 , December 31, 2019 or June 29, 2019 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 June 27, 2020 , December 31, 2019 and June 29, 2019 , the Company had $4.4 million , $3.9 million and $2.2 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 June 27, 2020 could decrease by approximately $1.1 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 2020 , 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 2016 through 2018 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 2014 taxable year. The Company is no longer subject to income tax examinations by any major foreign tax jurisdiction for years prior to 2013.
