EMP EMP Oil Pan Gasket 3.0L #801111 $115.99 $143.98
EMP 801111 Engine Gaskets An oil pan gasket that's leaking or deteriorated isn't something you want to ignore on a marine engine. Oil in the bilge is a problem on its own, and running low on oil because of a slow leak is a fast way to cause serious engine damage. This EMP oil pan gasket is a direct replacement for all 3.0L/181 CID GM-based marine engines, covering a wide range of inboard and sterndrive applications across multiple brands. The gasket is designed to seal the oil pan to the engine block and hold up to the heat cycles and vibration that marine engines deal with on the water. Getting the right gasket for your specific engine is straightforward with this part, as it covers the full range of 3.0L GM marine engine applications rather than a narrow subset. This part replaces OEM numbers across Marine Power, Mercury, OMC, Volvo Penta, and Sierra, so if you're cross-referencing from any of those brands, you're in the right place.
