Its possible the gauge is at fault. If you havent done it already I would suggest verifying the engine temps using an infra-red temp gun before you do anything to the engines. Get very close and point it at the thermostat housing. If the engines prove to actually be running at those temps then the thermostats are the first things to check because they are the parts that are supposed to regulate the temps.
