Yamaha - Water Pump Housing - Cooling System Component - F2.5 - 69M-G4311-00-00

Overview

On a compact outboard like the Yamaha F2.5, the cooling system is simple but absolutely critical. This water pump housing sits at the heart of that system, holding the impeller and directing water flow through the engine. When it’s in good shape, your motor stays properly cooled and runs smoothly. But if it’s worn or damaged, water flow can drop off quickly, leading to overheating. Replacing it during routine service helps keep your cooling system working efficiently and your engine protected.
