Troubleshooting & FAQ
How can I be sure this impeller fits my Honda engine?
This impeller is designed for Honda 4-stroke outboards from 35 HP to 60 HP. Please check the "Compatible Engine Models" table and cross-reference your engine's model number and the OEM part number (19210-ZV5-003 or 19210-ZV7-003).
What are the signs of a failing water pump impeller?
Common signs include the engine overheating at idle or low speeds, a weak or intermittent water stream from the "tell-tale" outlet, or a complete lack of water flow. A brittle or cracked impeller found during inspection also warrants immediate replacement.
How often should I replace the water pump impeller?
For preventative maintenance, it is recommended to inspect the impeller annually and replace it every 1-2 years or every 100-200 hours of use, depending on operating conditions (e.g., saltwater vs. freshwater).
