Sierra part # 18-0147 water pump gaskets
These gaskets are a great tool to help in your boating maintenance. Sierra has years of manufacturing expertise to ensure an exact fit for water pump gaskets to your original equipment. To avoid leakage of exhaust, heat and pressures caused from the engine running, gaskets are used.
The water pump gasket comes as a complete set with precise CAD cut gasket to eliminate hand cutting or trimming for proper alignment. The typical thickness for these water pump gaskets can range up to 1/16". When joining the two surfaces, an exact match is not always possible, therefore, it is recommended that during the installation process, to clean both surfaces to the bare metal and apply a thin layer of RTV silicone sealer on the surface side to ensure the ultimate seal.
The thin layer coating is applied prior to installation on each surface side. Sierra offers these fiber gaskets, based on years of manufacturing experience, eliminating the guess work out of what will work on your next job.
