Troubleshooting & FAQ
How do I confirm this impeller fits my exact engine model?
The best way is to match your engine's model and year against our compatibility table. If you are still unsure, compare the part number from your service manual (e.g., 6L5-44352-00-00) to our part number matrix. Visually comparing your old impeller's dimensions and blade count with our technical specs also helps.
What are common signs of a failing water pump impeller?
Key indicators include a weak or no water stream from the engine's tell-tale outlet, engine overheating alarms, and a decrease in overall engine performance. A worn, cracked, or brittle impeller cannot pump water efficiently, leading to cooling problems.
How often should I replace my outboard's impeller?
As a general maintenance rule, it is recommended to replace the impeller every 1–2 years or every 100–200 hours of use, whichever comes first. Usage in saltwater or sandy/silty conditions may require more frequent replacement.
