Yamaha OEM Water Pump Kits & Impellers

The water pump impeller is the rubber part that moves cooling water through the outboard, and it wears whether the motor is run or stored. A worn impeller is the most common cause of an overheat alarm. These are genuine Yamaha water pump repair kits and impellers. A kit includes the impeller plus the gaskets, seals and, where Yamaha specifies it, the housing or wear plate.

Frequently asked questions

How often should the impeller be replaced?

Follow the interval in your Yamaha owner's manual. Replace it any time the motor has been run dry or has picked up sand.

Kit or impeller only?

The kit suits a scheduled service because the gaskets and seals are replaced with the impeller. An impeller alone suits a pump whose housing is in good condition.

Which kit fits my motor?

Look up your model in the Yamaha parts diagrams or send us the model and serial number.

What else is in the cooling system?

Yamaha thermostats and the rest of the Yamaha cooling parts.
