OK, still a little confused. You have the powerhead off, correct. The engine runs cool, but the shift handle and exhaust housing gets hot, correct?
You mention that all the cooling water is directed out of the cooling upper cooling outlet. Admittedly, I have never looked closely at this area, but guess I should have. Others have mentioned that there is a relief hole that allows some cooling water down into the exhaust housing. I don’t think I have a 10hp exhaust housing apart, but will look. Perhaps someone else has one apart and could post pictures. In any event, I wouldn’t put the engine back together until this issue has been clarified. I’m thinking you could end up with some strange problem/failure letting that exhaust housing/shift handle heat up like that.
