OK, reread the entire post, you have not had the powerhead off yet….So, are you saying that the engine runs at normal temp with your overboard tap in place? Will it overheat if you plug it off? Once again, I don’t want you to “fix” something that isn’t broken…These engines normally run pretty warm/hot, especially the exhaust cover and cylinder head…Block temp is checked on the right side of the block on the vertical water passage that leaves the powerhead.
If the engine runs too hot with your overboard tap plugged off, then the next step is to pull the powerhead. Order the two gaskets first, remember what I said about the wrong gaskets…You will need three gaskets: there is one between the powerhead and pan, there is another between the inner exhaust tube and motor pan, and the third one between the exhaust housing and motor pan…
