Guys,
After changing the thermostat this weekend she is still running hot. At the dock at 1200 RPM she was running 190-200 deg. I tested the thermostat prior to installation and it was working properly. I also tested the old thermostat and it was opening on the high side of 190. I am getting water out of the exhaust so I know water is flowing. I believe I may have gotten some crud broken loose in the engine and want to perform a good flush on the engine with muradic acid. I am tired of loosing weekends and may just purchase the MM502 water pump to replace the original one that I currently have on the engine now. The water pump may just be tired and I know I will get a good flush if I had a strong pump on the engine. Any other ideas?
Chief
