Function

The water pump circulates cooling water through the engine block and cylinder head to maintain proper operating temperature. Over time, the impeller and pump components wear from heat, debris, and normal use.

Replacing the water pump components with this repair kit helps restore proper cooling flow, engine reliability, and protection against overheating.


Important Compatibility Note

Water pump kits vary depending on engine model, gearcase type, and serial number range. Always verify compatibility using the engine model and serial number before ordering to ensure the correct replacement kit.
