Hi everyone, I am having an issue with a 85hp chrysler 1973. At full throttle for approx 40 sec of running my temperature warnig light comes on and then I back the throttle off to 3/4 throttle the light goes off untill I hit full throttle again. I do not feel any excessive heat!:confused: It spitting a good flow of water. I recently had the impellor replaced, and the thermo sensor for my indicating light. Any suggestions? I am going to replace the thermostat just because i am not sure the last time it was replaced. I bought the boat knowing the impellor needed to be replaced.
Would the thermostat have anything to do with this problem?

Re: Not so full speed ahead.

Usually in fresh water the thermo isin't the culprit.When they changed the impeller they might have missed some pieces of the old impeller or the impeller is bad again(you use muffs?)or the lower unit wasn't put on right. Check these.Jerry
