Sierra Impeller Gasket for Marine Water Pumps

Sierra impeller gaskets are replacement water pump gaskets (also called impeller housing gaskets or water pump cover gaskets) for marine engines and outboard and sterndrive cooling systems. They seal the water pump housing so the pump can keep the water pressure and flow your engine needs to stay cool.

Key Features:

• Designed to seal the impeller housing or cover against the pump body
• Helps prevent raw water leaks and loss of pump efficiency
• Made for the demands of marine use, including exposure to water and heat cycling
• Sold as an aftermarket replacement for original equipment gaskets
• Backed by Sierra International, a long-established supplier of marine replacement parts

Replace the gasket whenever you service the water pump or change the impeller. This helps keep the cooling system sealed and protects your engine from overheating. Choose the correct part number for your engine and pump from the available options.
