Yes. I actually went in to ask about converting it to either keel cooling
or heat exchanger. They said not to bother under the circumstances. Since
that was turning down a potential grand of labor, I think they were probably
telling me the truth as they see it.

Nice thing about raw water and wet exhaust is that there is only one pump.
If something interrupts the water flow, you are alerted by the smoke and
smell of burning rubber hose before you overheat and ruin your engine

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?)
