Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	Note 1 – Significant Accounting Policies Interim Financial Statements. Brunswick's unaudited interim condensed consolidated financial statements have been prepared pursuant to 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 2023 Annual Report on Form 10-K for the year ended December 31, 2023 (the 2023 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 2024 ended on September 28, 2024 and the third quarter of fiscal year 2023 ended on September 30, 2023.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Th e effective tax rate for the three months ended September 28, 2024 and September 30, 2023 was 32.3 percent and 28.9 percent, respectively. The effective tax rate for the three months ended September 28, 2024 was higher than the same period in the prior year, primarily due to the discrete income tax expense recorded associated with an increase in the state valuation allowance. The effective tax rate for the nine months ended September 28, 2024 and September 30, 2023 was 23.8 percent and 33.4 percent, respectively. The effective tax rate for the nine months ended September 28, 2024 was lower than the same period in the prior year, primarily due to the prior year intercompany sale of certain intellectual property rights from one of our affiliates in Norway to the United States, partially offset by the discrete income tax expense recorded associated with an increase in the state valuation allowance. The Company has evaluated the effects of the Global Anti-Base Erosion Model Rules set forth by the Organization for Economic Co-operation and Development (OECD), referred to as “Pillar Two”, which establishes a global minimum corporate tax rate of 15 percent. The Company has determined that Pillar Two legislation has been enacted in one or more of the jurisdictions in which we operate and the Company is within the scope of the legislation. The Company assessed such enacted legislation, and, as applicable, the transitional safe harbor provisions of Pillar Two, and concluded that the tax effects are not material to the financial statements. 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 2020 through 2022 tax years. The Company is open to state and local tax audits in major tax jurisdictions dating back to the 2017 taxable year. The Company is no longer subject to income tax examinations by any major foreign tax jurisdiction for years prior to 2016.

Business Combinations [Abstract]
Business Combination Disclosure [Text Block]	Acquisitions 2024 Acquisition On September 12, 2024, the Company acquired additional Freedom Boat Club franchise operations and territories in Southeast Florida. The acquisition enhances Freedom Boat Club's presence in Florida and provides an opportunity to leverage synergies across Brunswick's portfolio of brands. The acquisition is included as part of the Company's Boat segment. The Company paid net cash consideration of $31.2 million for the acquisition. The opening balance sheet, which is preliminary and subject to change in the measurement period as the Company finalizes the purchase price allocation and fair value estimates, includes $28.2 million of goodwill and $5.2 million of customer relationships. The amount assigned to customer relationships will be amortized over the estimated useful life of 10 years. Transaction costs associated with the acquisition were not material to the Company's consolidated results of operations. The acquisition is not material to the Company's net sales, results of operations, or total assets during any period presented. Accordingly, the Company's consolidated results of operations do not differ materially from historical performance as a result of the acquisition, and pro forma results for prior periods are not presented. 2023 Acquisitions During the fourth quarter of 2023, the Company acquired additional Freedom Boat Club franchise operations and territories in the Southeast United States. These acquisitions should unlock operational efficiencies while providing members with additional boating destinations, as the Company plans for continued expansion across the Southeast Coastal region. These acquisitions are included as part of the Company's Boat segment. The Company paid net cash consideration of $16.0 million for these acquisitions. The opening balance sheets, which are preliminary and subject to change in the measurement period as the Company finalizes the purchase price allocation and fair value estimates, include $12.9 million of goodwill and $3.3 million of customer relationships. The amount assigned to customer relationships will be amortized over the estimated useful life of 10 years. Transaction costs associated with these acquisitions were not material to the Company's consolidated results of operations. On September 1, 2023, the Company acquired all of the issued and outstanding shares of Fliteboard Pty Ltd (Fliteboard) for $88.3 million net cash consideration. Fliteboard is a leader in eFoiling technology, which combines advanced hydrofoils and electric propulsion on the water. The acquisition of Fliteboard allows the Company to enter the emerging electric-foiling surfboard market and presents the opportunity for technological, manufacturing, commercial and consumer synergies with our existing portfolio. Fliteboard is included as part of the Company's Propulsion segment. The opening balance sheet includes $38.0 million of goodwill, $20.7 million of trade names, $8.4 million of customer relationships, and $7.1 million of developed technology. The amounts assigned to customer relationships and developed technology will be amortized over the estimated useful lives of 15 years and 10 years, respectively. Transaction costs associated with the acquisition of $1.9 million were expensed as incurred within Selling, general and administrative expense in 2023. Purchase accounting is final as of September 28, 2024. These 2023 acquisitions are not material to the Company's net sales, results of operations, or total assets during any period presented. Accordingly, the Company's consolidated results of operations do not differ materially from historical performance as a result of the acquisitions, and pro forma results for prior periods are not presented.
