Yamaha - Impeller - Water Pump Component - 6F5-44352-00-00

Overview

The Yamaha Impeller | 6F5-44352-00-00 is one of those parts you don’t think about—until your engine starts running hot. It’s what keeps water moving through the cooling system, and when it wears down, you’ll see it fast in weak water flow or rising temps. On smaller outboards especially, the impeller does a lot of work every time you’re on the water. Swapping it out regularly is one of the easiest ways to avoid overheating issues.
