Installation Notes
- Disconnect the spark plug wire(s) and shift the outboard into neutral.
- Remove the lower unit (gearcase) from the outboard's driveshaft housing.
- Locate and unbolt the water pump housing cover to expose the old impeller.
- Note the rotational direction of the existing impeller blades before removal.
- Remove the old impeller, key, and any gaskets. Clean all mating surfaces thoroughly.
- Install the new key and lightly lubricate the new impeller with marine grease or a soap/water solution.
- Slide the new impeller onto the driveshaft, turning the shaft in its normal rotational direction to bend the blades correctly.
- Reinstall the water pump housing, gaskets, and bolts, tightening to the manufacturer's specified torque.
- Reattach the lower unit to the outboard and test the engine in water, ensuring a steady stream from the tell-tale outlet.
Troubleshooting & FAQ
How do I know if my impeller needs replacing?
Common signs of a worn or failed impeller include a weak or nonexistent water stream from the tell-tale outlet, engine overheating alarms, or visible cracks, stiffness, or melted blades upon inspection.
What is the recommended replacement interval?
For optimal reliability and engine protection, it is best practice to replace the water pump impeller every one to two years or every 100-200 hours of operation, depending on usage and water conditions.
Will this fit my engine if the model is not listed?
Do not assume fitment. This impeller is specifically designed for the models indicated in the compatibility chart. Using an incorrect impeller can lead to poor cooling performance and severe engine damage. Always cross-reference your engine's OEM part number.
Is grease or sealant needed for installation?
Yes, it is highly recommended to apply a light coat of marine-grade grease or a simple soap and water solution to the interior of the pump housing and the impeller itself. This lubrication prevents damage to the blades during the initial dry start-up.
