Good To Know

Q: What does a water pump impeller kit do? A: The impeller moves cooling water through the outboard water pump to carry heat away from the engine. A worn impeller reduces flow and can cause the motor to run hot.

Q: When should this kit be installed? A: Install a fresh water pump impeller kit after about 100 hours of use or every season in saltwater. Inspect the old impeller for cracked or missing blades during each service.

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