I have recently purchased dory with a 1990 60 hp Evinrude. I had problems with the idle and discovered that the thermostat had been removed. I refitted a new stat and now find the engine is overheating. I have removed the stat cover and run the engine and get good gush of water. The tell tale is flowing well. Any help appreciated. Should I take the head off? What about deflectors?

Re: 1990 60 HP Evinrude Overheating

Had a friend with same problem on a Mercury 50hp. He tried to back flush through thrermo housing with lower unit removed and also tried air pressure(made up a cover and gasket combo). This didn't help. Water impeller had already been replaced. <br /> Suggested he get a manual from mercury which he did and he ended up pulling head and found an obstruction(never did tell me what it was) must of been ashamed or something?<br /> Suspicious that thermo was missing?
