Sierra Marine exhaust riser gaskets are engineered to meet or exceed manufacturer specifications—and provide added value to boaters and marine mechanics. Exhaust manifolds and risers take a beating in the marine environment and require regular inspection to avoid catastrophic engine failure. After an inspection (or replacement), it's equally important to replace the riser gaskets to maintain separation of exhaust and cooling channels. Sierra Marine exhaust riser gaskets are designed to perfectly match exhaust and cooling ports. They're available in restrictor and non-restrictor models for specific applications.
