I have searched the forum and found many posts but I haven’t found an answer to normal operating temperatures for a kohler 5ecd with a 195 degree thermostat. Has been running at 213-215 degrees with ac, battery charger, fridge all running. Hasn’t shutoff but after reading other posts I feel that is too hot. I have replaced thermostat, bled system many times with bleed screw, flushed heat exchanger, replaced anode, checked and replaced oil, even changed fresh water pump even though after taking that booger off it seemed to show no wear and was turning, water impeller is good, water flow looks good over side of boat and temp is not hot maybe luke warm. so what is the normal operating temp? I’ve seen a manual with 195-219 listed but it seems if I’m running 213-215 with cooler lake temps it will overheat in summer once it warms up. Any advice is much appreciated! Thanks!
