Restore the structural integrity and cooling efficiency of your outboard with this New Outboard Water Pump Housing manufactured by EMP. This professional-grade replacement component is specifically engineered for Johnson and Evinrude 2-cylinder and 3-cylinder engines produced from 1983 to present.
The water pump housing is a vital part of the cooling assembly, providing the internal structure and seal necessary for the impeller to generate consistent water pressure. Over time, original housings can suffer from heat distortion, internal scoring, or hairline cracks due to debris, all of which lead to a significant loss of cooling pressure. This unit is precision-engineered to meet or exceed original equipment specifications, ensuring a proper fit 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 immediately, as plastic components may have warped or lost their structural integrity.
