Trying the air was something I had thought about, just haven’t got to it yet. The motor was given to me so I don’t know it’s water usage history. When I had the head off, I didn’t see any evidence of salt water use. I tried running a wire into the water tube where it joins the pump and it seemed fine. I’ll use the air through that line as well as the leg exit ports, now that I know where they are. I figured I might have to remove the powerhead and look where the water exits the block and goes to the leg. That would only be if all these other test show nothing. I’m guessing that this higher temp I’m measuring is too much, but if I have water spitting out the leg, I’ll consider ir normal and let it run until something shows.
Thanks for the suggestions, I’m starting to learn Johnson outboards for a change.
