Restore the integrity of your cooling system with this New Outboard Water Pump Housing manufactured by EMP. This professional-grade replacement component is specifically engineered for Johnson and Evinrude 2-cylinder outboard engines produced between 1989 and 1996.
The water pump housing is a vital part of the cooling assembly, providing the internal structure necessary for the impeller to generate consistent water pressure. Over time, original housings can suffer from heat distortion, internal scoring, or hairline cracks, all of which lead to a loss of cooling efficiency. This unit is precision-engineered to meet or exceed original equipment specifications, ensuring a proper seal and protecting your powerhead from the risks of overheating.

Additional Information
NOTE: When replacing the water pump housing, it is highly recommended to install a new impeller and wear plate at the same time to ensure a complete seal. A smooth, unmarred internal surface is essential for the impeller to create the vacuum required for effective cooling. If your outboard has experienced a previous overheat event, the housing should be replaced as plastic components may have warped or melted.
