Troubleshooting & FAQ
How do I know if this impeller kit fits my Honda outboard?
This kit fits specific Honda 4-stroke models from 8 HP to 20 HP, generally from years 2002–2006. To ensure compatibility, please verify your exact engine model and year against the detailed compatibility table provided on this page.
What are the signs of a failing water pump impeller?
Common signs of a worn or damaged impeller include the engine overheating at idle or low speeds, a weak or intermittent water stream from the "tell-tale" outlet, and in some cases, a steam-like exhaust. Prompt replacement is crucial to prevent severe engine damage.
How often should I replace my outboard's water pump impeller?
As a critical preventative maintenance item, it is recommended to inspect the impeller annually and replace it every 1-2 years or every 100-200 hours of operation, whichever comes first. Usage in saltwater or silty/sandy conditions may require more frequent replacement.
