Q: How can I be sure this kit fits my specific engine model?
A: The best way is to match the OEM part number from your engine’s service manual or by looking up your model and serial number in the parts catalog. Cross-reference this number with the list provided in our compatibility tables. When in doubt, contact us with your engine details.
Q: What are the common symptoms of a worn or failed water pump impeller?
A: The most common signs include the engine overheating at idle or low speeds, a weak or non-existent stream of water from the "tell-tale" outlet, or a high-temperature alarm from your helm gauges.
Q: How often should I replace my engine's water pump impeller?
A: As a general rule, it is recommended to inspect the impeller annually and replace it every 1-2 years or every 100-200 hours of use, whichever comes first. Refer to your engine’s service manual for specific maintenance intervals.
