The impeller is the heart of your engine's cooling system, circulating water through the block to prevent catastrophic overheating. This unit is precision-molded from premium marine-grade elastomers to ensure maximum flexibility and durability. It serves as a direct-fit replacement for several original equipment part numbers, restoring the reliable cooling performance required for older horsepower models.

Additional Information
NOTE: For vintage engines, regular impeller replacement is the best insurance against engine failure. When performing this service, we recommend inspecting the water pump housing and wear plate for any signs of heat damage or grooving. If the housing is compromised, a complete water pump repair kit should be installed to ensure adequate water pressure at all speeds.
