Sierra Marine Water Pump Impeller Impellers

Sierra marine water pump impellers are replacement raw water pump impellers for inboard, sterndrive and outboard engines. The impeller moves cooling water through the engine and lower unit. Replacing it on schedule helps keep engine temperatures stable and protects against overheating.

Key Features:

• Flexible rubber vanes seal against the pump housing to keep water flowing
• Made as aftermarket replacements for the original equipment impellers in marine cooling systems
• Built for repeated flexing and continuous use in salt water and fresh water
• Designed to match the fit and performance of the original part
• Direct replacement that usually needs no modification

Sierra has supplied marine engine parts and accessories for many years. Choose the impeller that matches your engine and pump application. Check the impeller regularly and replace it as part of routine maintenance to protect your engine's cooling system.
