[QUOTE="renn90, post: 443245, member: 23002"] Typical for this motor? Just sorting out my recently purchased 1994 Johnson 20 HP. the water coming out of the telltale is cool to warm and the water/exhaust coming out of the exhaust relief is very hot (port at the rear-top of midsection, above the water line). It is too hot to touch for more than 5 seconds or so. To memory, all my other outboards were approximately the same temp from each exit point. (Ran today in a cold water PA river). The power head feels only warm to the touch, except for one spot (top of head, on the port side). The hot spot won't burn a hand but it is pretty hot. I had the head cover off to change the t-stat, and all passages were wide open. The head gasket appears to be fairly new (blue color, and clean). [/QUOTE]
