Exhaust Manifold Elbow Riser Gasket 3850496 2-Pack for Volvo Penta OMC Cobra 4.3-8.1L
Exhaust Manifold Elbow Riser Gasket 3850496 2-Pack for Volvo Penta OMC Cobra 4.3-8.1L
Product Overview
Exhaust manifold elbow riser gasket 2-pack for Volvo Penta GL, Gi and GXi engines and OMC Cobra 4.3L to 8.1L engines rated 200, 225, 270, 300 and 320 HP. It replaces Volvo Penta 3850496 and 3863191, OMC Cobra 913783, 909786 and 351325, plus Sierra 18-0943. The high-temp composite gaskets are fitted dry between the manifold and riser, and the pack supplies both joints. A failed gasket shows up as water weeping at the joint, exhaust soot around the elbow or a raw-water leak onto the engine. Replace both gaskets whenever the riser or elbow is removed.
