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
Warranty: 1 year on new genuine parts (subject to correct installation and normal use).
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.
