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\u003e47-78242\u003c\/strong\u003e is a Sierra marine oil filter under the Sierra brand, fitting GM L4, L6, and V8 marine engines in the short-style configuration. The short style is specified where engine bay clearance prevents use of a standard-length filter — confirm the customer’s engine requires the short style vs. standard before ordering. GM-block engines appear across MerCruiser, OMC, and some Volvo Penta applications; verify the specific platform and engine code.
