Troubleshooting & FAQ
How do I know if this impeller fits my engine?
First, check the "Engine & Model Compatibility" table on this page. Verify your engine's brand, horsepower, and year range. Second, use the "Part Number Matrix" to see if your old part number is listed as a direct cross-reference. If you are still unsure, compare the dimensions in "Technical Specs" with your old part.
What are the signs of a failing water pump impeller?
Common symptoms include the engine overheating at idle or low speeds, a weak or non-existent "telltale" water stream, and a melted water pump housing. Brittle, cracked, or missing impeller blades are clear signs that replacement is overdue.
How often should I replace my outboard's impeller?
For preventative maintenance, it is recommended to replace the impeller every 1-2 years or every 100-200 hours of operation, whichever comes first. Usage in saltwater or sandy/murky water may require more frequent changes.
Why is my engine still overheating after replacing the impeller?
If overheating persists, check for other blockages in the cooling system, such as in the thermostat, water intake screens, or internal cooling passages. Also, ensure the impeller was installed with the blades oriented correctly and that the key is properly seated on the driveshaft.
