I would like to know what the designed Engine Operating Temperature is for the MR-1 4 Stroke Yamaha FX - 140.
I have searched and cannot find any data or information with exception of if the Alarm Sounds it's over heating or if it's not then it's OK!?
I cannot accept that due to the train of thought, The Devices monitoring are man made and can fail to provide correct information on so many levels, Q/A failure on manufactured parts, Wire Harness, ECU programming ( only as Smart as Person that Programmed it), ETC...............
Thermostat opens at 124 - 145 Deg's F. This indicates to me the Operational Temp may be 150 - 170 Deg's F but not sure. I want to Know, Please respond if you actually Know.

Thanks
