Yamaha - Water Pump Housing - 60, 70, 75, 90 Cooling System Component - 688-44311-01-00

Overview

On these mid-range Yamaha two-strokes, the water pump housing is what keeps the cooling system working the way it should. It holds the impeller in place and directs water up through the engine, keeping temps under control. If it gets worn or scored, you’ll lose water pressure fast—and that’s when overheating problems start creeping in. Swapping it out during a pump service is a smart move to keep everything flowing strong and reliable.
