Why Replace the Complete Water Pump?
The water pump is essential to maintaining proper engine cooling. The impeller and surrounding components are subject to continuous wear and exposure to heat, water, and contaminants. Simply replacing an impeller may not always be enough if the housing, cover, spacer, collar, or other components are worn.
This complete kit provides the major water pump components needed to properly service the assembly and help restore reliable cooling performance.
Genuine Yamaha OEM Components
This kit uses genuine Yamaha components engineered to Yamaha specifications for proper fit and performance.
