Product Details

The Sierra 18-2833-9 is a full-flow composite exhaust elbow gasket engineered as a direct OEM replacement for MerCruiser stern drive engines. Sold as a pack of two, these gaskets seat between the exhaust manifold and the elbow (riser), providing a reliable seal that maintains proper separation of exhaust and cooling channels. Designed for use with raw water cooling systems, they fit riser mounting flanges with a square bolt pattern measuring 2-13/16" x 3-1/16" bolt centers.

Sierra gaskets meet or exceed original equipment manufacturer specifications, giving boaters and marine mechanics confidence that the job is done right the first time. Always replace exhaust elbow gaskets whenever inspecting or servicing your exhaust manifolds or risers to prevent leaks and protect your engine from the harsh marine environment.
