Seems to be getting plenty of water, removed the thermostat all together, still pegging 240. I pulled the fresh water hose off and it shot a solid stream of water, checked the thermostat housing for blockage seems clean. Without the thermostat I should never get to operating temp let alone over heat right? After about 3 minutes of wide open running on the lake it pegged out again but when idled it cools off on its own. Any suggestions before I chop it up and mount a radiator and electric fan?
