Hi Jeremy,
I don't do any specific winterizing on the water sytems.
I'm just across the pond from you in the area I
call Pacific South West (Canada)... I would call
Alaska the real PNW. But then again marketing is
not something anywhere near my realm of
expertise. However, keeping a boat in our waters
all year 'round is something I've done for 40 years.
Most of the time I keep the venerable "cube
heater" on minimum for the winter. It keeps the
boat interior near 40 F degrees (I'm seem to be
stuck in imperial measures too). The period of a
power any power outage so far has not allowed for
any negative freezing condition inside the boat,
even though the marina ice can get 1/2" thick
(imperial measure again :). As Patrick points out
there is a large moderating influence by the boat
sitting in 45 F degree water.
Don't worry. Be happy. And make yourself an nice
"boat coffee" the next time you check on her.
Cheers, Russ

Here in the Pacific NW (Vancouver)Â we're
getting freezing weather now, which rarely
happens. Many people keep a small ceramic
heater running in their boats, but what if the shore power goes out?
Here is what I did last week to prep:
1. Run 2QM20 raw water cooled engine under load
for 20min to warm it up. Stop
engine. Close seacock. Open sea strainer.Â
Start engine. Pour RV antifreeze into the sea
strainer. Stop engine. Close sea strainer.   Â
2. Drain fresh water holding tank system. Run
RV antifreeze through the pump and faucet.
3. Put RV antifreeze in the head and pump into
empty holding tank. Run macerator enough to get antifreeze in lines. Â
4. Put RV antifreeze in the bilge
What do others do? Any tips?
Thanks,
 Jeremy
