Yamaha - Water Pump Housing (Jet Drive) - F75, F80, F90, F100 - 67F-44311-11-00

Overview

On jet drive setups, the water pump housing plays a bigger role than most people think. It’s what holds the impeller and directs cooling water through the system, keeping everything from overheating under load. If the housing gets worn, warped, or scored, you’ll lose efficiency fast—and that can turn into bigger cooling issues. Swapping it out during a pump rebuild is a smart move to keep everything flowing the way it should.
