Overview

On these smaller Yamaha outboards, the water pump housing is what keeps your cooling system doing its job. It holds the impeller in place and directs water up through the engine to prevent overheating. If the housing gets worn or scored, you’ll lose water pressure and cooling efficiency pretty quickly. It’s one of those parts that’s worth replacing during a pump service to keep everything running cool and reliable.
