6. Lift off the old housing and remove the impeller, wear plate, gaskets, and seals.
7. Thoroughly clean the mating surfaces on the gearcase and driveshaft.
8. Install the new gaskets, wear plate, and key onto the driveshaft.
9. Coat the new housing interior with a thin layer of soapy water and slide the new impeller onto the driveshaft, turning the shaft clockwise to seat the vanes correctly.

Troubleshooting & FAQ

How do I confirm this kit fits my specific engine?
The best way is to match your engine's model, horsepower, and year to the detailed compatibility chart above. This kit fits a very broad range of Johnson/Evinrude outboards from 75-250 HP built between 1993 and 2009, but checking your exact model is crucial for a guaranteed fit.

What are the signs of a failing water pump impeller?
Common symptoms include the engine overheating, especially at idle or low speeds, and a weak or non-existent water stream from the "tell-tale" outlet on the motor. A brittle or cracked impeller discovered during routine maintenance is also a clear sign for replacement.

How often should I replace the water pump kit?
For optimal reliability, it is recommended to inspect the impeller annually and replace the entire water pump kit every 1-2 years or 100-200 hours of use. This interval can be shorter if you frequently operate in sandy or silty water.

Does this kit include the housing?
Yes, this is a complete repair kit. It includes the impeller, the upper housing with a stainless steel liner, the lower plate, and all necessary gaskets, o-rings, and hardware for a full replacement.
