- Carefully lift the housing off the driveshaft, noting any gaskets or seals.
- Inspect the housing interior and wear plate for deep grooves, warping, or cracks. Replace if damaged.

- Install the new drive key and slide the new impeller onto the shaft.
- Apply a light coat of marine grease to the inside of the pump housing.
- Push the housing down over the impeller while turning the driveshaft clockwise to correctly flex the vanes.
- Secure the housing with its bolts, reattach the lower unit, and test the engine in water to confirm proper water flow.
Troubleshooting & FAQ
How do I confirm this impeller fits my specific engine?
The best way is to cross-reference your engine's original part number with those listed in our Part Number Matrix. You can also check your engine's model, horsepower, and year against the Engine & Model Compatibility table. If you are unsure, check your service manual or contact a qualified marine mechanic.
What are the signs of a failing water pump impeller?
Common signs include a weak or non-existent "telltale" water stream from the engine, engine overheating alarms, or a noticeable decrease in engine performance. A worn or damaged impeller cannot effectively pump cooling water.
How often should I replace my impeller?
As a general maintenance rule, it's recommended to inspect your impeller annually and replace it every 1-2 years, or after every 100-200 hours of use, depending on operating conditions (e.g., saltwater vs. freshwater).
Why is my engine overheating even after replacing the impeller?
If overheating persists, check for other blockages in the cooling system, such as clogged water intakes, thermostat issues, or debris in the water passages. Also, ensure the impeller housing and wear plate are not excessively worn, as this can prevent a proper seal.
