Troubleshooting & FAQ

Q: How can I be sure this kit will fit my Yamaha engine?

A: The best way to ensure compatibility is to verify your engine's model and year against the "Compatible Engine Models" table. Additionally, you can cross-reference your existing part number with those listed in the "Part Number Cross-Reference" section.

Q: What are the symptoms of a failing water pump impeller?

A: Common signs include the engine overheating at low speeds, a weak or non-existent "telltale" water stream, or a dry, cracked, or deformed old impeller upon inspection.

Q: How often should the impeller be replaced?

A: As a general maintenance guideline, we recommend replacing the impeller every 1 to 2 years or every 100-200 hours of operation, depending on usage conditions (e.g., saltwater vs. freshwater).

Q: Is this an OEM part?

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.

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.
