Hayden Posted April 22, 2012 Author Share Posted April 22, 2012 Ok,, so I changed out both thermostats and the impeller,,, skied last night for a couple of hours, boat ran awesome and the heater reroute as suggested in the post about the LT1 overheating problem worked great too. I also moved the head crossover tube to the front of the heads. The boat ran a constant 160. The only problem being that the red overheat light on the dash will not go out.. Is there a reset for this or could the sending unit be bad? Thanks Link to comment Share on other sites More sharing options...
