Sierra 18-0916 Water Pump Gasket, Replaces Mercruiser 27-8052151, 27-805215, 27-94915, 27-72779

The Sierra 18-0916 Water Pump Gasket is a round marine engine gasket designed to seal the water pump housing on inboard and sterndrive engines. It is built to meet or exceed the quality of the original equipment part it replaces, making it a reliable choice for engine maintenance and water pump rebuilds. This gasket is supplied as a single unit and is intended for direct replacement of a specific set of Mercruiser gaskets, so it is commonly used when servicing or rebuilding a water pump assembly on compatible marine engines. Because a worn or damaged water pump gasket can allow coolant or raw water to leak past the pump housing, replacing it with a properly sized, OEM-quality gasket like the 18-0916 helps maintain a correct seal and proper cooling flow. Boat owners and marine technicians use this gasket when installing a new water pump, rebuilding an existing pump, or performing routine cooling system maintenance.
