Troubleshooting & FAQ
Q: How do I confirm this kit fits my specific engine model?
A: The best way is to check the "Compatible Engine Models" table on this page. Match your engine's brand (Suzuki, Johnson/Evinrude), model, horsepower, and year range. Cross-referencing your existing part number with our "Part Number Cross-Reference" table is another reliable method.
Q: What are the signs of a failing water pump impeller?
A: Common signs include a weak or non-existent water stream from the "tell-tale" outlet, engine overheating alerts, and, in severe cases, steam from the exhaust. Reduced engine performance can also be a symptom.
Q: How often should the water pump impeller be replaced?
A: For optimal performance and to prevent overheating, most manufacturers recommend replacing the water pump impeller every 1-2 years or every 100-200 hours of operation, whichever comes first. This interval can vary depending on usage conditions (e.g., saltwater vs. freshwater).
