Troubleshooting & FAQ
Q: How do I confirm this kit fits my specific engine?
A: The best way is to check the "Compatible Engine Models" table on this page. Match your engine's model, horsepower, and year with the listed applications. You should also cross-reference your existing part number with those in the "Part Number Cross-Reference" table.
Q: My engine is a Yamaha F80B. Why won't this kit fit?
A: The Yamaha F80B models from 2005-2015 require a different water pump kit, OEM part number 67F-W0078-00-00. This kit (68V-W0078-00-00) is not compatible with that specific engine series.
Q: What are common signs that my water pump impeller needs replacement?
A: Key indicators include the engine overheating at idle or low speeds, a weak or inconsistent stream of water from the tell-tale port, or a brittle, cracked, or deformed impeller found during routine inspection.
Q: How often should I replace the water pump impeller?
A: For preventative maintenance, it is recommended to inspect the impeller annually and replace it every 1-2 years, depending on usage (hours) and operating conditions (saltwater vs. freshwater). Frequent use in sandy or silty water may require more frequent replacement.
Q: OEM vs. Aftermarket?
A: This listing is an aftermarket replacement part (not an OEM component). We build to OEM specifications using comparable-grade materials. Production is done in an ISO9002-certified facility, and each batch is inspected for consistent performance.
Q: How fast do you ship and how much does it cost?
A: We offer fast global shipping—typically 5–15 days worldwide—and standard shipping is free. Expedited options are available at checkout depending on your location.
Q: What is your warranty and return policy?
A: This product includes a 1-year warranty against manufacturing defects under normal use. If something goes wrong, contact our support team with your order details. Returns are accepted within our standard return window (unused & in original condition); please see our policy page or reach out for instructions.
