Probably the biggest problem is that your wet exhaust will freeze up
-- it freezes before the surrounding water because of less mass and
more exposure to cold air. Also of course the water in the heads and
your FW system. The water system can be treated with potalbe
anti-freeze, but the raw-water side of the cooling probably can't. If
you inadvertently start the engine up with the raw water frozen either
or both of two things will happen: the engine will overheat, and
maybe the raw-water impeller will be destroyed.

All this can be avoided by reliable heat inside the boat. I keep
"Barbara" in year-round in Maine,but I also takae precautions.

Thank you, that helps.
What are the precautions you take, and how do you heat the boat?

TIA
