Re: 1995 evinrude 115 overheating
dyma82 I once had a 50 evinrude that had a over heating problem at low speeds. I changed thermostats and water pumps several time, without any success. The motor only heated after about five minutes of 5 mph opperation.<br />I finially pulled the head expecting to find it plugged, but it was not. What I did discover was the head gasket was leaking hot combustion gases into the water jacket. At higher speed the increased flow of water would cool the motor.<br /><br />Your problem seems to be just the opposite. I know on automotive motors that incorect timing can cause overheating. I don't know if timing could have the same effect on outboards.<br /><br />Another thing. Is your 115 hp power head a cross flow type motor? If it is you may need to change the water deflector in the block. These are four pieces of rubber hose in the block that serve as little dams that cause the water to flow around the cylinder walls in a certain direction. They list for $2.50 each and should be a common idem at your omc dealer. The can become desttored and restrict proper flow of colling water.<br />I was told it is necessary to replace them if the motor has over heated.<br />Hope this helps you In I think of anything else I'll let your know.
