Sierra Sierra Manifold End Cap Gasket #18-2850-1 $7.79 $9.16
Sierra 18-2850-1 Engine Gaskets The manifold end cap gasket is one of those small parts that does a quiet but important job. It seals the end of the exhaust manifold, keeping exhaust gases and cooling water where they belong and out of places they shouldn't be. When this gasket fails, you'll typically see signs of exhaust leakage, water intrusion, or corrosion around the end cap, none of which you want to ignore on a marine engine. The Sierra 18-2850-1 is a direct OEM-spec replacement that installs cleanly and seals reliably. Sierra has been producing marine engine components for decades, and their gaskets are manufactured to match the original equipment dimensions and material specs. If you're doing a manifold service, rebuilding the cooling system, or replacing a leaking end cap, this gasket is the right part to have on hand before you button everything back up.

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.

EMP 801096 Engine Gaskets Valve Cover Gasket, 3.0L Marine Engine The EMP 801096 is a valve cover gasket designed for 3.0L marine engines. If your valve cover is seeping oil or you're doing a top-end refresh, this is the gasket that seals the valve cover to the cylinder head and keeps oil where it belongs. A straightforward part, but one that matters every time you fire up the engine. This gasket is a direct replacement for the original Marine Power 801096 and crosses to several common OEM and aftermarket part numbers, making it easy to confirm fitment against what's already on your engine. EMP manufactures this gasket to meet or exceed original equipment specifications for the 3.0L application.
