Hi again Fellas.
My 1987 Johnson 70 VRO is still getting an overheat signal from the sender. This after I have replaced the thermostat with a brand new one. It starts when I have been up on the plane for a few minutes and stops soon after I drop down to idle. The engine is hot to the touch but by no means hot enough to burn your hand if you don’t take it away. Pee hole water is lukewarm.
My questions are the following;
1 Can a temperature sensor “fail” and kick in at a lower temperature ? I have not tested this yet cause I have to wait for the wife to go to work so I can use the stove without her knowing.
2 Can salt build up internally to the point where it restricts the flow of water to the powerhead causing the overheat, and if so which point within the circuit is the most common ?
3 Is there a flush additive that one can flush salt build-up away other than the one you would use after each run in the ocean? Ie one that removes deposits built up over time ?
4 What do women want ?
