Exhaust Manifold Gasket SIERRA 18-0956-1

Compatible Engines

The original SIERRA 18-0956-1 exhaust manifold gasket is a critical component ensuring a tight seal in the exhaust system of marine propulsion units. This product is specifically designed for MERCRUISER/OMC Ford 460 CID MCM 3.7L engines. Thanks to precise matching with factory dimensions, it guarantees an ideal seal of connections, which is essential for maintaining correct exhaust pressure and protecting the boat interior from fume ingress. Using this part prevents gas leaks and protects other components from overheating.

Installation and Maintenance

When replacing the gasket, we recommend thoroughly cleaning contact surfaces from old sealant residues and checking the manifold flatness. Installation must be performed according to the manufacturer's torque specifications to avoid deformation. Regular inspection of the gasket condition prevents costly failures and extends the lifespan of the entire exhaust system.
