Compatible Engines

The professional SIERRA exhaust manifold gasket (catalog number 118-2902-1-9) is a critical component ensuring the integrity of the exhaust system in marine outboard engines. This product is specifically designed for popular OMC/VOLVO PENTA units, including models with displacements of 5.0L (variants GL, GXI, OSI) and 5.7L (variants GL, GI, GXI, GIL, GXIL, OSI, OSXI). Thanks to precise manufacturing, the gasket effectively prevents exhaust leaks, contributing to stable engine performance and safety on the water.

Installation and Maintenance

During replacement, we recommend thoroughly cleaning the mounting surfaces from carbon deposits and old sealant. Check that the manifold has no deformations that could affect sealing. When installing the new gasket, tighten the bolts in a cross pattern, adhering to the torque specified by the engine manufacturer to avoid cracking the material. Regular inspection of the gasket condition prevents costly failures.
