Good To Know

Q: What does the 50° rating mean for my outboard? A: It indicates the thermostat starts opening at 50 degrees Celsius (122°F), which is a common regulation temperature for these Yamaha engines. This helps maintain efficient operation.

Q: Can I use this thermostat on other Yamaha models? A: It is specifically designed for the listed F75, F80, F90, F150, and VF250 engines, so other models may require a different thermostat. Always verify compatibility.
