Amuller,
I had a 1979 85hp Evinrude. Every once in a while it would alarm for no reason. Never ran hot as I would feel the heads & they were not hot. I have no idea why this happened. No overheated paint or wiring too. I always was on the lookout for plastic garbage in the water too, Jerks for trashing our water!!

The cooling system on your 79 V4 had two thermostats and two relief valves. So, it was possible to have one bank heat up while the other did not. The scenario you describe is pretty common for that set up…Don’t know why though…Usually occurs when you first start it after sitting for awhile…Fortunately, just revving up the engine to pop open the relief valves usually solves the problem…Which is a good thing, that system was hard to get at and a pain to work on…
