Re: Air Cooled Outboard Overheating

[oltimer]

I am "guessing/trying to remember" as per what PM T2 had said earlier about a cooling spray to the lower exhaust inside. I had a unit that was overheating with the same type of engine years ago. There was a tube that picked up water (as the unit moved forward) from the bottom to spray inside near the exhaust to cool it. The carbon at the exhaust area inside had overly built up and was closing the water spray to virtually nothing coming through. Once this was all cleaned out the engine ran hot; but never over heated to shut it down again.
