OEM Thermostat Options
Prefer an OEM thermostat? Pro Marine stocks both the Yamaha OEM and Suzuki OEM versions of this thermostat family.
Yamaha OEM F12411-1 122°F / 50°C Thermostat
Genuine Yamaha OEM thermostat for compatible Yamaha engines using 60V-12411-00-00 or 68V-12411-00-00.
Suzuki OEM 17670-90J21 50°C / 122°F Thermostat
Genuine Suzuki OEM thermostat for compatible Suzuki applications using 17670-90J20 or 17670-90J21.
What This Thermostat Does
The thermostat regulates cooling-water flow through the engine so the powerhead can reach and maintain the correct operating temperature.
When the engine is cold, the thermostat restricts cooling-water flow. As the engine reaches approximately 122°F / 50°C, the thermostat begins opening to allow additional cooling water to circulate.
Proper thermostat operation helps support correct engine warm-up, fuel management, combustion quality and overall cooling-system performance.
Common Signs of a Thermostat Problem
- Engine running hotter than normal
- Overheat alarm or warning
- Thermostat stuck closed and restricting cooling water
- Engine running too cool because the thermostat is stuck open
- Salt, mineral or corrosion buildup
- Damaged thermostat spring or valve
- Thermostat does not open at the correct temperature during testing
