GM and Chevrolet-based marine engines are used across multiple sterndrive and inboard platforms. Verify the correct filter thread size, bypass valve rating, and anti-drainback valve requirement for your specific engine. Confirm whether your installation requires the long or short style before ordering.\u003c\/p\u003e\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\u003cp\u003eDrain the engine oil fully before replacing the filter. Lightly lubricate the filter gasket with clean engine oil before installation. Tighten hand-tight plus 3\/4 turn, or to the torque specification in your engine service manual. Do not over-tighten. Check for leaks after the first start and verify oil pressure is within the normal operating range.\u003c\/p\u003e\u003ch2\u003eParts Desk Insights\u003c\/h2\u003e\u003cp\u003eSKU \u003cstrong\u003e47-78761\u003c\/strong\u003e is a Sierra marine oil filter under the Sierra brand, long-style configuration for GM\/Chevrolet marine engines. Compare against the short-style Sierra filter (47-78242) — the long style is preferred where clearance allows, as the additional filter media can extend service intervals. GM-block engines appear across MerCruiser, OMC, and some Volvo Penta applications; verify the specific platform and engine code.\u003c\/p\u003e","brand":"LNS","offers":[{"title":"Default Title","offer_id":43563827822628,"sku":"47-78761","price":19.39,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/7f8b1de9-13bd-4dde-b2e1-541a8596095c.png?v=1783361786","url":"https:\/\/marisolmarine.com\/products\/sierra-47-78761-marine-oil-filter-gm-chev-long","provider":"Marisol Marine Company","version":"1.0","type":"link"}
