About this part
Genuine Yamaha 6J8W0078A200 (Water pump repair kit) — an OEM replacement part built to Yamaha standards. OEM specification helps avoid common fitment issues and supports long-term reliability on the water.
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: Yamaha variations can exist within the same year. The safest approach is to confirm the part number against your exact model code / serial range before purchase.
