Ensure the longevity and cooling efficiency of your engine with this New Outboard Water Pump Impeller manufactured by EMP. This high-quality component is designed for Johnson and Evinrude outboard engines produced between 1973 and 1978, specifically covering high-horsepower 4-cylinder and 6-cylinder models, as well as select 2-cylinder units.
The impeller is the heart of your engine's cooling system, responsible for circulating water through the powerhead to prevent overheating. This replacement unit is precision-molded from a durable, chemical-resistant neoprene compound to maintain flexibility and provide maximum lift. It features a 6-blade design and is a direct-fit replacement for several original equipment part numbers.

Additional Information
NOTE: For a complete cooling system service, we recommend inspecting the water pump housing, wear plate, and gaskets. Often, replacing the entire water pump kit is more effective than replacing the impeller alone if the housing shows signs of scoring or heat damage. If you require a full water pump repair kit, please contact us through the website or email.
