Troubleshooting & FAQ

Q: How do I confirm this impeller fits my Honda engine?
A: Check your engine model and year against the "Compatible Engine Models" table. This part is designed for Honda BF8D, BFP8D, BF9.9D, BFP9.9D, BF10D, and BFP10D models. Also, verify that your current part matches OEM number 19210-ZW9-013 or 19210-ZW9-003 by checking your engine's service manual.

Q: How often should I replace the water pump impeller?
A: For optimal performance and to prevent overheating, we recommend replacing the impeller every 200 hours of operation or annually, whichever comes first. This interval may shorten depending on usage conditions (e.g., frequent use in sandy or silty water).

Q: What are the signs of a failing impeller?
A: Common signs include a weak or non-existent water stream from the engine's tell-tale port, frequent engine overheating alarms, and a noticeable decrease in overall engine performance. A visual inspection of the old part may reveal cracked, brittle, or worn-out blades.

Q: Is there a difference between the BF and BFP models that use this impeller?
A: While the BF (standard) and BFP (Power Thrust) models have different gearcase and drive configurations, they share the same water pump impeller for the specified horsepower and year ranges. Compatibility is based on the engine block's cooling system design.
