Q: How do I confirm this kit fits my specific engine model?
A: First, check the "Compatible Engine Models" table to see if your model, HP, and year range are listed. For Mercury/MerCruiser engines, it is critical to verify your serial number against the notes in the table. You can use the provided serial number guide to help locate it. Cross-referencing the OEM part number (e.g., 47-43026T06, 8M0100526) with your engine's service manual is the most reliable method.
Q: What are the signs that my water pump impeller is failing?
A: The most common symptoms are engine overheating, especially at idle or low speeds, a weak or intermittent water stream from the "tell-tale" outlet, or a low water pressure reading on your gauges. A brittle or cracked impeller discovered during inspection also requires immediate replacement.
Q: How often should I replace the water pump impeller?
A: As a general rule for preventative maintenance, it is highly recommended to replace the impeller every 1 to 2 years or every 100-200 hours of operation, whichever occurs first. This interval can be shorter if you frequently operate in sandy or silty water.
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.
