Troubleshooting & FAQ
How do I know if my impeller needs replacing?
Common signs of a failing impeller include the engine overheating at idle speeds, a weak or non-existent water stream from the "telltale" outlet, or visible cracks, brittleness, and worn blades upon inspection.
What is the recommended replacement interval?
For optimal performance and to prevent overheating, we recommend inspecting your impeller annually and replacing it every 1 to 2 years (or every 100-200 hours of use), especially if you operate in saltwater or sandy/silty conditions.
Will this fit my BF200A manufactured in 2007?
Yes, this impeller is compatible with all Honda BF200A models from 2007 and later, including the BF200AK0, BF200AK1, BF200AK2, and BF200AK3 variants.
What is the difference between this part and the full service kit?
This listing is for the 19210-ZY3-003 water pump impeller only. The complete service kit (Honda part #06192-ZY3-000) is a more comprehensive package that also includes the impeller gasket, O-ring, and the driveshaft key.
