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. Certain previously reported amounts have been reclassified to conform to the current period presentation, including reclassifying the Deferred income tax liability in the prior period to Other long-term liabilities on the Condensed Consolidated Balance Sheets. 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 2016 Annual Report on Form 10-K for the year ended December 31, 2016 (the 2016 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 three quarters of fiscal year 2017 ended on April 1, 2017 , July 1, 2017 and September 30, 2017 , and the first three quarters of fiscal year 2016 ended on April 2, 2016 , July 2, 2016 and October 1, 2016 . Recent Accounting Pronouncements. The following are recent accounting pronouncements that have been adopted during 2017 , or will be adopted in future periods. Hedge Accounting : In August 2017, the Financial Accounting Standards Board (FASB) amended the Accounting Standards Codification (ASC) 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 amendment is effective for interim and annual periods beginning after December 15, 2018, with early adoption permitted. The Company is currently evaluating the impact of adopting this ASC amendment, but does not expect it will have a material impact on its condensed consolidated financial statements. Presentation of Benefit Costs : In March 2017, the FASB amended the ASC related to the income statement presentation of the components of net periodic benefit cost for an entity’s sponsored defined benefit pension and other postretirement plans. The amendments require entities to present the current-service-cost component with other current compensation costs in the income statement and present the other components outside of income from operations. The amendment is effective for interim and annual periods beginning after December 15, 2017, with early adoption permitted. The Company is currently evaluating the impact of adopting this ASC amendment, but does not expect it will have a material impact on its condensed consolidated financial statements. Statement of Cash Flows Classifications : In August 2016, the FASB amended the ASC to add and/or clarify guidance on the classification of certain transactions in the statement of cash flows. The amendment is to be applied retrospectively and is effective for fiscal years, and the interim periods within those years, beginning after December 15, 2017, with early adoption permitted. The Company is currently evaluating the impact it will have on its Condensed Consolidated Statements of Cash Flows. Share-Based Compensation : In March 2016, the FASB amended the ASC to simplify the accounting for employee share-based payment transactions. The Company adopted this amendment during the first quarter of 2017 , and recognized $7.7 million of net excess tax benefits related to share-based payments in the income tax provision for the nine months ended September 30, 2017 . These net excess tax benefits were historically recorded in additional paid-in capital when recognized. Additionally, the Company adopted the amendment retrospectively for presentation of net excess tax benefits on the Condensed Consolidated Statements of Cash Flows, resulting in an increase of $11.1 million in Net cash provided by operating activities and Net cash used for financing activities for the nine months ended October 1, 2016 . The Company also elected to recognize forfeitures of share-based awards as they occur. The remaining amendments, including those related to statutory withholding requirements, did not have a material impact. Recognition of Leases : In February 2016, the FASB amended the ASC to require lessees to recognize assets and liabilities on the balance sheet for all leases with terms greater than twelve months. Lessees will recognize expenses similar to current lease accounting. The amendment is to be applied using a modified retrospective method with certain practical expedients, and is effective for fiscal years and interim periods within those years, beginning after December 15, 2018, with early adoption permitted. The Company is currently evaluating the impact that the adoption of the new standard will have on its condensed consolidated financial statements. Revenue Recognition : In May 2014, the FASB issued a final standard on revenue recognition which outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers. This standard will supersede current revenue recognition guidance. Under the new standard, entities are required to identify the contract with a customer; identify the separate performance obligations in the contract; determine the transaction price; allocate the transaction price to the separate performance obligations in the contract; and recognize the appropriate amount of revenue when (or as) the entity satisfies each performance obligation. In August 2015, the FASB amended the ASC to delay the effective date to fiscal years, and the interim periods within those years, beginning on or after January 1, 2018, from the original effective date of January 1, 2017, with early adoption permitted no earlier than January 1, 2017. Entities have the option of using either retrospective transition or a modified retrospective approach in applying the new standard. The Company plans to use the modified retrospective approach in applying the new standard. The Company’s implementation process is progressing as planned and there are no significant implementation matters that have yet to be addressed. The Company does not expect the standard to have a material impact on its condensed consolidated financial statements, however, the most meaningful changes will be in the Boat and Fitness segments. In the Boat segment, certain customers are offered retail promotions that are currently recorded at the later of when the program has been communicated to the customer or at the time of sale. Under the new standard, these promotions will now be estimated and recognized at the time of sale, primarily upon shipment to customers. In the Fitness segment, certain customer contracts include product rebates recorded in cost of sales at the time of sale. Under the new standard, the Company will no longer record the rebate at the time of sale; however a portion of revenue will be deferred and not recognized until the rebate is redeemed. As a result, the Company expects a change in the timing of recording certain promotions and rebates, including but not limited to those described above, however, it does not expect a change in the total amount of cumulative revenue recognized for each transaction.

Restructuring and Related Activities [Abstract]
Restructuring, Exit and Integration Activities [Text Block]	Restructuring, Exit and Integration Activities In the third quarter of 2017, the Company recorded restructuring charges within the Fitness segment for the write-down of inventory and tooling related to the exit of the InMovement product line as a result of declining demand. In the second and third quarters of 2017, the Company implemented headcount reductions in the Fitness and Boat segments aimed at improving general operating efficiencies. As a result of these actions, the Company recorded restructuring charges within these segments during 2017. In the first quarter of 2017, the Company announced that it will close its boat manufacturing facility in Joinville, Santa Catarina, Brazil, as a result of continued market weakness due partially to unfavorable foreign currency impacts in the region. The facility manufactures certain Bayliner and Sea Ray boat models for the Latin American market. The long-lived assets at this facility were previously fully impaired. In the first quarter of 2017, the Company also recorded restructuring charges within Corporate related to the transition of certain corporate officers. The Company acquired Cybex International, Inc. (Cybex) and Indoor Cycling Group GmbH (ICG) in the first and third quarters of 2016, respectively, and initiated certain integration activities within the Fitness segment related to these acquisitions. As a result, the Company recorded integration charges in 2017 and 2016 related to Cybex and recorded integration charges in 2016 related to ICG. The following table is a summary of the expense associated with the restructuring, exit and integration activities for the three months ended September 30, 2017 and October 1, 2016 , as discussed above: September 30, 2017 October 1, 2016 (in millions) Fitness Total Fitness Total Restructuring and exit activities: Employee termination and other benefits $ 1.6 $ 1.6 $ — $ — Current asset write-downs 2.6 2.6 — — Other 0.4 0.4 — — Integration activities: Employee termination and other benefits 0.4 0.4 0.6 0.6 Professional fees 1.6 1.6 1.6 1.6 Other 0.2 0.2 0.2 0.2 Total restructuring, exit and integration charges $ 6.8 $ 6.8 $ 2.4 $ 2.4 The following table is a summary of the expense associated with the restructuring, exit and integration activities for the nine months ended September 30, 2017 and October 1, 2016 , as discussed above: September 30, 2017 October 1, 2016 (in millions) Corporate Fitness Boat Total Fitness Total Restructuring and exit activities: Employee termination and other benefits $ 2.4 $ 3.7 $ 2.6 $ 8.7 $ — $ — Current asset write-downs — 2.6 7.2 9.8 — — Professional fees — — 0.8 0.8 — — Other — 0.4 1.0 1.4 — — Integration activities: Employee termination and other benefits — 2.4 — 2.4 2.7 2.7 Professional fees — 4.2 — 4.2 3.8 3.8 Other — 0.4 — 0.4 2.3 2.3 Total restructuring, exit and integration charges $ 2.4 $ 13.7 $ 11.6 $ 27.7 $ 8.8 $ 8.8 During 2017 , the Company made cash payments of $12.5 million relating to all restructuring, exit and integration activities, including payments related to prior period activities.

Share-based Compensation [Abstract]
Share-Based Compensation	Share-Based Compensation Under the Brunswick Corporation 2014 Stock Incentive Plan, the Company may grant stock options, 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, 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 30, 2017 , 5.4 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 a nominal number of stock awards during the three months ended September 30, 2017 and did not grant any stock awards during the three months ended October 1, 2016 . The Company granted 0.2 million and 0.3 million of stock awards during the nine months ended September 30, 2017 and October 1, 2016 , 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 30, 2017 , the Company charged $2.9 million and $8.5 million , respectively, and charged $2.9 million and $7.4 million during the three months and nine months ended October 1, 2016 , respectively, to compensation expense for non-vested stock awards. As of September 30, 2017 , there was $10.8 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 1.3 years . Performance awards In February of both 2017 and 2016 , the Company granted 0.1 million performance shares to certain senior executives. The 2017 and 2016 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 stock returns measured against stock returns of a predefined comparator group over a three-year performance period. Additionally, in February 2017 and 2016 , the Company granted 26,300 and 37,430 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 nine months ended September 30, 2017 , the Company charged $2.8 million and $5.9 million , respectively, and charged $1.4 million and $4.4 million for the three months and nine months ended October 1, 2016 , 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 2017 and 2016 were $64.82 and $38.54 , respectively, which were estimated using the Monte Carlo valuation model, and incorporated the following assumptions: 2017 2016 Risk-free interest rate 1.5 % 0.8 % Dividend yield 1.1 % 1.0 % Volatility factor 38.3 % 40.8 % Expected life of award 2.9 years 2.9 years The fair value of the certain officers' and certain senior managers' performance awards granted based solely on the CFROI and OM performance factors was $58.77 and $37.76 in 2017 and 2016, respectively, which was equal to the stock price on the date of grant in 2017 and 2016 , respectively, less the present value of expected dividend payments over the vesting period. As of September 30, 2017 , the Company had $4.7 million of total unrecognized compensation cost related to performance awards. The Company expects this cost to be recognized over a weighted average period of 1.1 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.

Income Taxes	Income Taxes The Company recognized an income tax provision from continuing operations for the three months and nine months ended September 30, 2017 of $30.0 million and $99.1 million , respectively, and included a net tax benefit of $0.8 million and $9.1 respectively, primarily associated with the net excess tax benefits related to share-based compensation which was recognized as an income tax benefit in accordance with recent changes in accounting guidance as discussed in Note 1 – Significant Accounting Policies . The Company recognized an income tax provision from continuing operations for the three months and nine months ended October 1, 2016 of $32.8 million and $109.1 million , respectively, which included net tax benefits of $3.2 million and $3.3 million , respectively, mainly associated with the reassessment of tax reserves and favorable valuation allowance adjustments. The effective tax rate from continuing operations, which is calculated as the income tax provision as a percentage of pre-tax income, for the three months and nine months ended September 30, 2017 was 27.5 percent and 27.3 percent , respectively. The effective tax rate from continuing operations for the three months and nine months ended October 1, 2016 was 27.8 percent and 29.8 percent , respectively. No deferred income taxes have been provided as of September 30, 2017 , December 31, 2016 or October 1, 2016 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 and other 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 30, 2017 , December 31, 2016 and October 1, 2016 , the Company had $2.3 million , $3.5 million and $3.8 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 September 30, 2017 could decrease by approximately $0.7 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 2017 , but the amount cannot be estimated. 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 2012 tax year and all open issues have been resolved. The Company is currently open to tax examinations by the IRS for the 2014 through 2016 tax years. The 2014 tax year is currently under examination and the Company has been notified by the IRS that it will also be examining the 2015 tax year. 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.

Significant Accounting Polici21

Significant Accounting Policies (Policies)	9 Months Ended

Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	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. Certain previously reported amounts have been reclassified to conform to the current period presentation, including reclassifying the Deferred income tax liability in the prior period to Other long-term liabilities on the Condensed Consolidated Balance Sheets.
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 three quarters of fiscal year 2017 ended on April 1, 2017 , July 1, 2017 and September 30, 2017 , and the first three quarters of fiscal year 2016 ended on April 2, 2016 , July 2, 2016 and October 1, 2016 .
Recent Accounting Pronouncements	Recent Accounting Pronouncements. The following are recent accounting pronouncements that have been adopted during 2017 , or will be adopted in future periods. Hedge Accounting : In August 2017, the Financial Accounting Standards Board (FASB) amended the Accounting Standards Codification (ASC) 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 amendment is effective for interim and annual periods beginning after December 15, 2018, with early adoption permitted. The Company is currently evaluating the impact of adopting this ASC amendment, but does not expect it will have a material impact on its condensed consolidated financial statements. Presentation of Benefit Costs : In March 2017, the FASB amended the ASC related to the income statement presentation of the components of net periodic benefit cost for an entity’s sponsored defined benefit pension and other postretirement plans. The amendments require entities to present the current-service-cost component with other current compensation costs in the income statement and present the other components outside of income from operations. The amendment is effective for interim and annual periods beginning after December 15, 2017, with early adoption permitted. The Company is currently evaluating the impact of adopting this ASC amendment, but does not expect it will have a material impact on its condensed consolidated financial statements. Statement of Cash Flows Classifications : In August 2016, the FASB amended the ASC to add and/or clarify guidance on the classification of certain transactions in the statement of cash flows. The amendment is to be applied retrospectively and is effective for fiscal years, and the interim periods within those years, beginning after December 15, 2017, with early adoption permitted. The Company is currently evaluating the impact it will have on its Condensed Consolidated Statements of Cash Flows. Share-Based Compensation : In March 2016, the FASB amended the ASC to simplify the accounting for employee share-based payment transactions. The Company adopted this amendment during the first quarter of 2017 , and recognized $7.7 million of net excess tax benefits related to share-based payments in the income tax provision for the nine months ended September 30, 2017 . These net excess tax benefits were historically recorded in additional paid-in capital when recognized. Additionally, the Company adopted the amendment retrospectively for presentation of net excess tax benefits on the Condensed Consolidated Statements of Cash Flows, resulting in an increase of $11.1 million in Net cash provided by operating activities and Net cash used for financing activities for the nine months ended October 1, 2016 . The Company also elected to recognize forfeitures of share-based awards as they occur. The remaining amendments, including those related to statutory withholding requirements, did not have a material impact. Recognition of Leases : In February 2016, the FASB amended the ASC to require lessees to recognize assets and liabilities on the balance sheet for all leases with terms greater than twelve months. Lessees will recognize expenses similar to current lease accounting. The amendment is to be applied using a modified retrospective method with certain practical expedients, and is effective for fiscal years and interim periods within those years, beginning after December 15, 2018, with early adoption permitted. The Company is currently evaluating the impact that the adoption of the new standard will have on its condensed consolidated financial statements. Revenue Recognition : In May 2014, the FASB issued a final standard on revenue recognition which outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers. This standard will supersede current revenue recognition guidance. Under the new standard, entities are required to identify the contract with a customer; identify the separate performance obligations in the contract; determine the transaction price; allocate the transaction price to the separate performance obligations in the contract; and recognize the appropriate amount of revenue when (or as) the entity satisfies each performance obligation. In August 2015, the FASB amended the ASC to delay the effective date to fiscal years, and the interim periods within those years, beginning on or after January 1, 2018, from the original effective date of January 1, 2017, with early adoption permitted no earlier than January 1, 2017. Entities have the option of using either retrospective transition or a modified retrospective approach in applying the new standard. The Company plans to use the modified retrospective approach in applying the new standard. The Company’s implementation process is progressing as planned and there are no significant implementation matters that have yet to be addressed. The Company does not expect the standard to have a material impact on its condensed consolidated financial statements, however, the most meaningful changes will be in the Boat and Fitness segments. In the Boat segment, certain customers are offered retail promotions that are currently recorded at the later of when the program has been communicated to the customer or at the time of sale. Under the new standard, these promotions will now be estimated and recognized at the time of sale, primarily upon shipment to customers. In the Fitness segment, certain customer contracts include product rebates recorded in cost of sales at the time of sale. Under the new standard, the Company will no longer record the rebate at the time of sale; however a portion of revenue will be deferred and not recognized until the rebate is redeemed. As a result, the Company expects a change in the timing of recording certain promotions and rebates, including but not limited to those described above, however, it does not expect a change in the total amount of cumulative revenue recognized for each transaction.
