About this part
Genuine Yamaha 67F124120000 (Seal, thermostat) — 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
Installation tip: renew gaskets/O-rings, clean mating faces, and verify related cooling components (where fitted) are free to move and not blocked by deposits.
Thermostats regulate operating temperature. A stuck thermostat can cause overheating or unstable temperature control. OEM parts help ensure the correct opening temperature and consistent regulation.
Warranty
New genuine parts include a 1-year warranty (correct application and installation required).
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.
