Q: How do I confirm this kit fits my engine?
A: The most reliable method is to check your engine's model, horsepower, and serial number against the detailed compatibility tables on this page. This kit is a direct replacement for several OEM part numbers, including Mercury/Mariner 47-43026Q06 and Honda 19021-ZW1-003. For Mercury owners, our linked serial number guide can help you verify your model.
Q: What are the signs of a failing water pump impeller?
A: The most common symptom of a bad impeller is engine overheating, often indicated by a warning alarm or gauge. Other signs include a weak or no water stream from the engine's "tell-tale" outlet, or an impeller that appears brittle, cracked, or has melted vanes upon inspection.
Q: How often should the impeller be replaced?
A: As a general maintenance rule, it is recommended to inspect the impeller annually and replace it every 1 to 2 years, or after every 100-200 hours of operation. Replacement frequency may depend on usage conditions, such as operating in saltwater or sandy/silty water, which can accelerate wear.

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.
