What is the proper operating temperature for 1989 Johnson v-4 140 motors? My motors die at the drop of a hat at docking speeds and I noticed today that the temp gauges never read above 50-60 F.

I'm thinking stuck open thermostat? When the motors are wamed up, what kind of temps should I be seeing?
