Hello All,
I am new to this forum, living in lower Alabama near the coast I recently purchased a used boat and motor my 4th boat
in 25 years. It is a 1977 bass boat with a 1977 Mercury 850. My quesion is can anyone tell me about the thermostat on this motor. All parts breakdown and manuals do not show a thermostat for this motor. I want to make sure all is good before I take her out. New water pump, spark plugs, timing,fuel lines, tank cleaned, wiring, ext. 140 PSI on all 4 cylinders. I am concerned that there may be a hidden thermostat in this motor. Or , how is the temp. controlled? is just flow or is somthing hidden in the motor I have missed? Thanks in advanced Guy's......
