Troubleshooting & FAQ

Q: How do I confirm this kit fits my Johnson/Evinrude engine?
A: Verify your engine horsepower (9.9, 10, or 15 HP) and year (1995–2001) against the compatibility table above. Cross-reference OEM part number 394711 with your service manual or parts diagram to ensure correct fitment.

Q: How often should I replace the water pump impeller?
A: Most manufacturers recommend replacing the water pump impeller every 2–3 years or 200–300 hours of operation, whichever comes first. If you notice reduced water flow from the telltale, overheating, or steam, inspect and replace the impeller immediately.

Q: What are the signs my water pump is failing?
A: Common symptoms include weak or absent water stream from the telltale indicator, engine overheating, steam from the powerhead, or an overheating alarm. Any of these signs warrant immediate inspection and impeller replacement.
