Ensure your compact outboard remains cool and reliable with this New Outboard Water Pump Impeller manufactured by EMP. This precision replacement part is specifically designed for Johnson and Evinrude 1-cylinder and 2-cylinder engines produced between 1967 and 1984.
The impeller is a critical component that draws water into the cooling system to prevent the engine from overheating. This unit is molded from high-quality, marine-grade elastomers, ensuring the blades stay flexible and durable even after periods of storage. It serves as a direct-fit replacement for the original equipment part number, restoring the water flow necessary for safe operation of your small-horsepower motor.

Additional Information
NOTE: Small outboards are often used in shallow water where sand and debris can accelerate impeller wear. We recommend a seasonal inspection of the water pump to ensure the blades are not cracked or "set" in a curved position. When replacing the impeller, check the water pump housing for internal scoring; a smooth housing is essential for maintaining the vacuum required for effective cooling.
