Good To Know

Q: How often should a water pump impeller be replaced? A: Most manufacturers recommend replacement every one to two seasons or after 100 hours of running time. Inspect the impeller whenever the water pump housing is opened.

Q: Will this kit fit my Johnson lower unit? A: This kit is designed for Johnson 5.5HP, 6HP, and 7.5HP outboards, but serial number ranges can vary. Confirm the OEM part numbers on your existing impeller before ordering.

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