Restore efficient water circulation in your small outboard with this New Outboard Water Pump Impeller manufactured by EMP. This component is specifically designed for Johnson and Evinrude 2-cylinder engines produced between 1980 and 2004, covering two decades of reliable small-horsepower models.
As a critical part of your engine's cooling system, the impeller is responsible for pumping water through the powerhead to maintain safe operating temperatures. This replacement unit is precision-engineered from high-quality, marine-grade elastomers to ensure flexibility and long-term durability. It serves as a direct-fit replacement for the original equipment part number, helping to protect your engine from the risks of overheating and premature wear.

Additional Information
NOTE: For portable outboards used in sandy or silty environments, the impeller is subject to increased abrasive wear. We recommend seasonal inspection to ensure the blades remain pliable and free of cracks. When installing, always check the water pump housing for internal scoring; a smooth housing surface is essential for the impeller to create the vacuum necessary for effective cooling.
