Water Pump Impeller 19210-ZW9-A32 - Fits 4-Stroke 8-20HP Outboards

Water Pump Impeller for Outboard Motors

A replacement water pump impeller for outboard motors.

Aftermarket part. Check the part number and impeller dimensions against your own engine before ordering — impellers are not interchangeable between models.

The impeller is the only thing cooling an outboard — replace it at the interval in your engine's manual, and always check for a telltale water stream after fitting.
