Clueless about cruisers, but what's that all for? I have 38' motorhome and use less then 1 gallon when I winterize it.

Fresh water system, HVAC, generator. I do all that myself and have the yard that pulls my boat blow pink through the engines. I'll probably have two gallons left over but I always plan a little heavy.
It's a pink bonanza!

May I ask why don't you just invest in a bilge heater and call it a day like I did or is the weather just too extreme up there and not worth taking the risk? Glad I don't have to mess with all that, but then again you have much more piece of mind when the tempature does drop into the teens.

Makes me wonder if I ever want to move up to a cruiser. Here in Wisconsin the pink is a must, but that seems like a lot of work! Bad enough putting my boat away for the winter.

For me, it's just part of the deal and the joy of having the boat far outweighs the work that goes into maintaining it. And I could have the yard do all of the winterization, but I feel like it's another way I get to bond with the boat and know with absolute certainty that it was done correctly. Besides, it only takes a couple of hours and there's no law against drinking while winterizing (just don't have pink cocktails while working with antifreeze ).

I only use three gallons of pink to winterize an entire cottage - 23 gallons for a cruiser seems extreme. Are you filling the tanks on your fresh water system? I'd think you need only drain the water, then run a bit of pink through the pump, and add a pint or so to any traps.
