About this part
Genuine Yamaha 68DE2413001S (Cover, 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?
Choosing genuine Yamaha OEM helps avoid problems often seen with pattern parts: mis-sized sealing profiles, inconsistent rubber compounds, poor plating, and connectors that don’t lock correctly. On a marine engine, those small differences can become big issues.
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
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.
