Good To Know

Q: How often should a water pump impeller be replaced? A: Most outboard makers suggest impeller service every few seasons or at set engine hour intervals, whichever comes first. Sandy or silty water shortens that interval.

Q: Can I install this kit without pulling the lower unit? A: No, the water pump sits above the lower unit, so the gearcase must be dropped to reach the impeller housing. A service manual for your model walks through the steps.

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