Pro Marine 60° Thermostat for Yamaha F75 F90 VF90
The Pro Marine 6FP-12411P is a premium aftermarket 60°C thermostat designed for select Yamaha F75, F90 and VF90 FourStroke outboards. It directly replaces Yamaha OEM 6FP-12411-00-00 along with Mercury cross-reference numbers 8M0175325 and 8M6010300, helping maintain proper engine operating temperature and cooling system performance.
Why Replace Your Thermostat?
Your thermostat controls engine operating temperature by regulating coolant flow.
