About this part
This page covers the genuine Yamaha part 6894431200CA (Cover Water Pump Housing). It’s an original OEM component designed to match Yamaha’s factory tolerances for correct fit, reliable function, and long service life in marine conditions.
Why choose genuine Yamaha?
OEM parts are produced to the same specification as the original component fitted at the factory. That means correct materials, correct dimensions and consistent fit — especially important on units where corrosion, heat cycles, and vibration are normal.
Notes for this part
Impellers are a key cooling-system service item. If the tell-tale is weak, cooling flow seems inconsistent, or you’re not sure when the pump was last serviced, replacing the impeller is sensible preventative maintenance.
Installation tip: inspect the wear plate and housing for scoring, and renew any O-rings or seals disturbed during disassembly. Avoid dry starts — ensure the leg is supplied with water before running.
Warranty
1-year warranty applies to new parts (terms apply; damage from incorrect installation isn’t covered).
Ordering tips
Ordering tip: when buying multiple items, it’s worth reviewing the same diagram section for related gaskets and seals so everything arrives together.
