I feel even better now that I've been down to the waterfront to get to know
my local Yamaha mechanic. I said, "2QM20" and he crossed is finger in the
air and said, "You're going to need a new engine. Those are all dying right
about now."

I told him the boat was from the Great Lakes and he said, "Oh, no problem.
In that case, it's a great engine and should be almost as good as new. You
should get 15 more years out of it easy."

BTW I'm a former sailing yacht and tall ship designer still designing
commercial power boats. Feel free to pick my brains about any boats you are
looking at.

Is that salt water cooled (i.e. no heat exchanger?)
