Good To Know

Q: What is the function of the impeller in a water pump? A: The impeller moves coolant through the engine block to regulate temperature. A worn impeller reduces flow and can cause overheating.

Q: How often should I replace the impeller kit? A: Yamaha recommends replacing the impeller every 300 hours or annually, especially in harsh conditions. Regular replacement prevents engine damage.

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