Good To Know

Q: How often should a water pump impeller be replaced? A: Replacement is generally recommended every season or after about 100 hours of use. A worn impeller can reduce cooling flow and cause overheating.

Q: Will this impeller work with Mercury outboard models? A: This impeller is designed for Mercury 85, 90, 120, 125, and 150HP models. Confirming the engine serial number before purchase is always recommended.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
