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 third quarter of fiscal year 2019 ended on September 28, 2019 and the third quarter of fiscal year 2018 ended on September 29, 2018 . 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. As a result, the Company classified the assets and liabilities of the Fitness business as held for sale on the Condensed Consolidated Balance Sheets for all prior periods. Additionally, this business, which was previously reported in the Company's Fitness segment, is being reported as discontinued operations in the Condensed Consolidated Statements of Comprehensive Income and Condensed Consolidated Statements of Cash Flows for all periods presented. See Note 3 – Discontinued Operations for further information. 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 $ — $ 80.1 $ 80.1 Long-term assets held for sale 610.3 21.1 631.4 Current liabilities Accrued expenses 502.1 16.4 518.5 Current liabilities held for sale 255.0 2.9 257.9 Long-term liabilities Other 101.6 (3.4 ) 98.2 Operating lease liabilities — 67.1 67.1 Long-term liabilities held for sale 99.6 18.2 117.8 The Company determines if an arrangement is a lease at lease inception. Operating lease 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 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 the Company 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.

Discontinued Operations and Disposal Groups [Abstract]
Disposal Groups, Including Discontinued Operations, Disclosure [Text Block]	Discontinued Operations On May 6, 2019, the Company announced that it reached an agreement to sell its Fitness business to KPS Capital Partners, LP. On June 27, 2019, the Company completed the sale. The sale resulted in net proceeds of $473.7 million and an after-tax loss of $45.0 million . In connection with the sale of its Fitness business, the Company retained assets of $26.4 million primarily related to VAT receivables, and retained liabilities of $45.1 million primarily related to VAT payables, product warranty liabilities and certain employee benefits. As of September 28, 2019 , retained assets and liabilities were $26.4 million and $42.6 million , respectively. In connection with the sale of the Fitness business, the Company entered into a Transition Services Agreement (TSA) with the purchaser to provide certain support functions for a period of up to twelve months following the sale. The TSA is not material to the Company's condensed consolidated financial statements. The Company does not have or anticipate having any significant continuing net cash flows associated with the 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. The Company no longer participates in the fitness industry and now solely focuses on its global marine portfolio. As a result, the Company classified the assets and liabilities of the Fitness business as held for sale on the Condensed Consolidated Balance Sheets for all prior periods. Additionally, this business, which was previously reported in the Company's Fitness segment, is being reported as discontinued operations in the Condensed Consolidated Statements of Comprehensive Income and Condensed Consolidated Statements of Cash Flows for all periods presented. The following table discloses the results of operations of the business reported as discontinued operations for the three months and nine months ended September 28, 2019 and September 29, 2018 , respectively: Three Months Ended Nine Months Ended (in millions) Sep 28, Sep 29, Sep 28, Sep 29, Net sales $ — $ 254.0 $ 448.3 $ 750.6 Cost of sales — 187.4 334.6 548.6 Selling, general and administrative expense (C) 3.2 58.3 112.3 153.0 Earnings (loss) from discontinued operations before income taxes (B) (C) $ (3.2 ) $ (7.0 ) $ (149.2 ) $ 17.5 Income tax provision (benefit) (0.3 ) (1.8 ) (40.7 ) 2.7 Earnings (loss) from discontinued operations, net of tax (B) (C) (2.9 ) (5.2 ) (108.5 ) 14.8 Loss on disposal of discontinued operations, net of tax (A) (3.5 ) — (45.0 ) — Net earnings (loss) from discontinued operations, net of tax $ (6.4 ) $ (5.2 ) $ (153.5 ) $ 14.8 (A) The Loss on disposal of discontinued operations for the three months ended September 28, 2019 includes a pre-tax loss of $4.7 million and a tax benefit of $1.2 million .

(B) In the first quarter of 2019, the Company re-evaluated the fair value of the Fitness reporting unit and determined the fair value of the business was less than its carrying value. As a result, Earnings (loss) from discontinued operations, net of tax, includes a $137.2 million ( $103.0 million after tax) goodwill impairment charge for the nine months ended September 29, 2019.

Restructuring and Related Activities [Abstract]
Restructuring, Exit and Integration Activities [Text Block]	Restructuring, Exit and Impairment Activities During 2019, the Company recorded restructuring charges within the Boat segment related to consolidating its commercial and government products operations in order to rationalize its product line to better align with customer demand. In addition, the Company announced headcount reductions aimed at streamlining the cost structure of its enterprise-wide general and administrative functions. The Company estimates approximately $13 million of charges will be incurred across the organization related to this action, with the majority recognized in the first nine months of 2019. In the second quarter of 2018, the Company ended the sale process of its Sea Ray business and, as a result of a change in the plan of sale, recorded an impairment of long-lived assets. In connection with this action, the Company recorded charges beginning in the second quarter of 2018 associated with the wind down of Sport Yacht and Yacht production, mainly relating to inventory write-downs, increased warranty liabilities and employee severance and retention bonuses. The Company also incurred transaction costs during the sale process. These costs were partially offset by the reversal of the valuation allowance for estimated transaction costs which was recorded when the assets and liabilities of Sea Ray were initially reclassified as held for sale. In 2018, the Company also executed headcount reductions in the Boat segment aimed at improving general operating efficiencies as well as recorded charges within Corporate related to the transition of certain corporate officers. The Company recorded restructuring, exit and impairment charges in the Condensed Consolidated Statements of Comprehensive Income as a result of the activities described above.

Share-Based Compensation	9 Months Ended

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 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 September 28, 2019 , 5.1 million shares remained available for grant. Share grant amounts, fair values, and fair value assumptions reflect all outstanding awards for both continuing and discontinued operations. 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 nominal stock awards during the three months ended September 28, 2019 and September 29, 2018 . The Company granted 0.4 million and 0.3 million of stock awards during the nine months ended September 28, 2019 and September 29, 2018 , respectively. 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 and nine months ended September 28, 2019 , the Company charged $3.5 million and $7.2 million , respectively, and charged $3.3 million and $8.4 million during the three months and nine months ended September 29, 2018 , respectively, to compensation expense for non-vested stock awards. As of September 28, 2019 , there was $12.3 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 1.4 years . Performance Awards In both February of 2019 and 2018 , the Company granted 0.1 million and 0.2 million performance shares to certain senior executives, respectively. 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 and nine months ended September 28, 2019 , the Company charged $1.7 million and $5.0 million , respectively, and charged $1.9 million and $3.0 million , for the three months and nine months ended September 29, 2018 , 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 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 September 28, 2019 , the Company had $4.1 million of total unrecognized compensation cost related to performance awards. The Company expects this cost to be recognized over a weighted average period of 1.0 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.

Refer to Note 14 – Postretirement Benefits and Note 13 – Income Taxes in the Notes to Condensed Consolidated Financial Statements for further information on the pension settlement and related income tax consequences, respectively.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company recognized an income tax provision for the three months and nine months ended September 28, 2019 of $43.3 million and $93.8 million , respectively. The income tax provision for both periods included a $17.2 million net provision related to the settlement of the Company's qualified defined benefit plans in the third quarter of 2019. The tax impact of this action consisted of a tax benefit of $74.2 million from the pension settlement charge, which was netted against a tax charge of $91.4 million resulting from the release of disproportionate tax effects in Accumulated Other Comprehensive Income. The Company recognized an income tax provision for the three months and nine months ended September 29, 2018 of $6.7 million and $48.4 million , respectively, which included net tax benefits of $10.7 million and $5.1 million , respectively. The net tax benefits of $10.7 million and $5.1 million were primarily associated with updates related to 2017 tax reform. 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 nine months ended September 28, 2019 was not meaningful as a result of the tax impacts resulting from the pension settlement discussed above. The effective tax rate for the three months and nine months ended September 29, 2018 was 8.2 percent and 18.9 percent , respectively. No deferred income taxes have been provided as of September 28, 2019 , December 31, 2018 or September 29, 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 September 28, 2019 , December 31, 2018 and September 29, 2018 , the Company had $3.5 million , $2.3 million and $2.6 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 September 28, 2019 could decrease by approximately $0.6 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 2016 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 2014 taxable year. The Company is no longer subject to income tax examinations by any major foreign tax jurisdiction for years prior to 2013.

Defined Benefit Plan [Abstract]
Pension and Other Postretirement Benefits	Postretirement Benefits The Company has defined contribution plans, qualified and nonqualified defined benefit pension plans and other postretirement benefit plans covering substantially all of its employees. The Company's contributions to its defined contribution plans include matching and annual discretionary contributions which are based on various percentages of compensation, and in some instances are based on the amount of the employees' contributions to the plans. See Note 18 in the Notes to Consolidated Financial Statements in the 2018 Form 10-K for further details regarding these plans. Pension Settlement. During 2019, total settlement payments of $672.9 million were made from the Brunswick Pension Plan for Salaried Employees (Salaried Plan) and the Brunswick Pension Plan for Hourly Bargaining Unit Employees (Bargaining Plan), consisting of lump-sum pension distributions of $77.1 million and the purchase of group annuity contracts totaling $595.8 million to cover future benefit payments. The annuity contracts unconditionally and irrevocably guarantee the full payment of all future annuity payments to the affected participants.

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 third quarter of fiscal year 2019 ended on September 28, 2019 and the third quarter of fiscal year 2018 ended on September 29, 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 $ — $ 80.1 $ 80.1 Long-term assets held for sale 610.3 21.1 631.4 Current liabilities Accrued expenses 502.1 16.4 518.5 Current liabilities held for sale 255.0 2.9 257.9 Long-term liabilities Other 101.6 (3.4 ) 98.2 Operating lease liabilities — 67.1 67.1 Long-term liabilities held for sale 99.6 18.2 117.8 The Company determines if an arrangement is a lease at lease inception. Operating lease 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 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 the Company 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.
