winterizing 360 aft cabin

[John Blodgett]

I am in the process of winterizing my 360 aft cabin, and would like little info in regards to dealing with my AC units in preparation for the cold weather?

Have similar boat. First year I used shop vac and blew out all water until just mist. Did it from the sea strainer, blocked all but one outlet at a time. Last 2 years I run unit and pour 2 gallons of propylene glycol (PINK) in strainer while units are on. It gets to -10c where we are. So far it has worked. You are much colder for longer you may need a different method or more pink.
