Hi
My 2002 Yamaha 70 two stroke runs cold. I tested the old thermostat and it seemed fine but I replaced it anyway thinking it may have been opening too early. A new thermostat made no difference and the engine still runs at about 45 deg C (110 F). I figure that 45C/110F is way too cold for good engine performance and engine life. I believe the temperaure should be around 85 C (180 F)
Can anyone help?
Cheers
