Troubleshooting & FAQ
How do I know if this impeller fits my engine?
Check the Part Number Matrix and Engine Compatibility tables on this page. The most reliable method is to match your existing OEM part number or confirm your exact engine model and year are listed. When in doubt, compare the visual images and dimensions to your old part.
What are the signs of a failing impeller?
Common signs include a weak or nonexistent water stream from the "telltale" outlet, engine overheating alerts, and reduced engine performance. Visible signs on the old impeller include cracked, brittle, or missing vanes.
How often should a water pump impeller be replaced?
As a preventative maintenance item, it is recommended to replace the impeller every 1–2 years or every 100–200 hours of operation, depending on usage conditions (e.g., saltwater vs. freshwater). Refer to your engine's service manual for specific intervals.
Is this impeller the same material as the OEM version?
Yes, this impeller is made from high-quality neoprene, the same durable, flexible material used in most OEM impellers to ensure longevity and performance in a marine environment.
Can I reuse my old water pump housing or gaskets?
It is strongly recommended to replace gaskets with new ones during an impeller change. Inspect the housing and wear plate carefully for deep grooves, warping, or corrosion. If any significant wear is present, the housing should be replaced to ensure proper pump pressure.
