I have a fresh water cooled Yanmar. Has any body considered blowing the lines clear? I actually added antifreeze last year and then blew it out with a shop-vac. I guess I should have kinda done it the other way around. I could have probably blown it dry and then chased it with half a gallon (or less) of antifreeze. I have an RV friend that says he catches the antifreeze from the sinks and reuses it every year. Any thoughts on blowing/leaving all the boat systems dry?
Anybody stay in the water through the winter? I was thinking that the water heater might keep the cabin above freezing. BTW I'm in the Chesapeake Bay.
