About this part
This page covers the genuine Yamaha part 6GR124130000 (Cover, thermostat). 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
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.
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.
Warranty
New genuine parts include a 1-year warranty (correct application and installation required).
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.
