Troubleshooting & FAQ

How do I confirm this kit fits my engine?
The most reliable method is to match your engine's model, horsepower, and year range to the compatibility table provided above. For final confirmation, you can compare the OEM part numbers listed (like 17400-96350) with your engine's service manual or by looking up parts diagrams for your specific model.

How often should I replace the water pump impeller?
As a general rule, it is recommended to replace your water pump impeller every 1-2 years or every 100-200 hours of use, whichever comes first. This interval can be shorter if you frequently operate in sandy, silty, or saltwater environments.

What are the signs of a failing water pump impeller?
Common signs include a weak or non-existent water stream from the "tell-tale" outlet, the engine overheating alarm sounding, or visible steam from the engine cowling. A damaged impeller can cause rapid and severe engine damage, so it is critical to address these symptoms immediately.
