Specs At A Glance

Good To Know

Q: Why does the water pump impeller wear out? A: The rubber impeller flexes constantly while the outboard runs, creating friction and heat. Replacing it on schedule keeps the cooling system working properly.

Q: Is this impeller kit for 2-stroke Yamaha models? A: No, this kit is intended for Yamaha 6HP, 8HP, and 9.9HP 4-stroke outboard engines. Confirm the engine type 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.
