Good To Know

Q: What does the housing do in this water pump impeller kit? A: The housing holds the impeller and directs cooling water through the lower unit so the engine stays within its operating temperature.

Q: How often should the impeller be replaced? A: Most outboard maintenance schedules recommend replacing the impeller every one to two seasons. Confirm the interval in the service manual for the specific 2-stroke model.

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