Yamaha - Water Pump Housing - F75, F80, F90, F100, C85 Cooling System Component - 67F-44311-01-00

Overview

This housing is what keeps your water pump working the way it should—holding the impeller in place and directing water through the engine. On these Yamaha motors, if the housing starts to wear or get scored, you’ll lose cooling efficiency fast. That usually shows up as weak water pressure or rising temps under load. Swapping it out during a pump service is a smart move to keep everything flowing right and avoid overheating issues.
