Yamaha T25, F30 & F40 4-Stroke Water Pump Housing | OEM Part 66T-44311-00-00

Maintain reliable cooling system performance with this Genuine Yamaha OEM Water Pump Housing (66T-44311-00-00). Designed for Yamaha T25, F30, and F40 4-Stroke outboards, this housing surrounds the water pump impeller and helps direct cooling water through the engine to regulate operating temperatures and prevent overheating.

Over time, sand, debris, mineral buildup, and corrosion can wear the housing's internal surfaces, reducing water flow and increasing impeller wear. Replacing the water pump housing during routine water pump maintenance helps restore cooling efficiency, extend impeller life, and protect your outboard from costly engine damage.
