Ensure the integrity of your cooling system with this New Outboard Water Pump Housing manufactured by EMP. This professional-grade replacement is specifically designed for Johnson and Evinrude 2-cylinder outboard engines produced between 1976 and 1994.
The water pump housing is a critical component that encapsulates the impeller and provides the necessary internal seal to generate water pressure. Over time, original housings can warp, melt, or develop hairline cracks due to heat or abrasive debris, leading to a significant loss of cooling efficiency. This replacement unit is precision-engineered to meet or exceed original equipment specifications, restoring the factory-standard water flow required to protect your powerhead from overheating.

Additional Information
NOTE: When replacing the water pump housing, it is highly recommended to install a new impeller, wear plate, and cup at the same time. A smooth, unmarred internal surface is essential for the impeller to create the vacuum required for effective cooling. If your engine has experienced an overheat event, the housing should be inspected immediately for signs of distortion or heat damage.
