"I have a 1987 regal with a 16
"I have a 1987 regal with a 165 3.7 4 cyl engine, closed cooling system.. I was experiencing what i thought was over heating the engine would get up to 190-5 when running.. and then it would seem to go into some reduce power mode??? (not sure if that was what was happening) I replace the lower unit pump. i checked all hoses for tightness and replaced a few, changed the thermostate, took off the resevour and checked for clogs, along with the exchanger. all looks good.
I reciently tuned it up, sparks plugs, and wires, distributer, points (set to specs) and cap and condencer, adjusted timing. Engine was running great at the slip.
When i run the boat at the dock at idle the temp goes up to 180, when i rev the engine the temp starts to come back down around 170. Next I take it out for a drive and in the harbor at 6mphs the temp stays about 180 then when i excelerate the temp climbs to about 190 and stays there. but then when i de-excelerated the motor kept wanting to stall.. i had to keep in high idle to keep it running.
Whats going on??? is the temp running right?? or is that hot??
Any help guys????"
