I was running a 1992 Johnson 60HP at idle on the muffs today checking things out. The motor was peeing fine. I normally run my hands in the water to see if it gets warm the cool then warm and cool. It was running warmer than usual so I checked the head and thermostat housing with an inferred gun. My temps were around 170F and climbing. Never got a overheating buzzer.
Does anyone know what temp these motors should be in this setting or what temp the buzzer should sound?
Thank you for any help.

It was salt corrosion causing the thermostat to stick open but not all the way.

Appears the engine head does not exceed 150F with a new thermostat.

Most likely the thermostat was stuck closed, their is a bypass in those motors so water was coming in and not circulating through the engine. Peeing is just a visual that the water pump is working...
