Hi Timucin,
try without Thermostat. Maybe the Thermostat does'nt allow enough flow. But first I would check your gauge.

hi andree ;
long time no post
thnx for help
hope everything is cool with you

Check your plugs on both engines. One might be running richer than the other (or the hot one could be lean).

I have heard of people drilling small holes in thermostat for more water flow .
