Lou - there are many articles in the association site about winterizing.  My process goes something like this:  1)Drain both tanks in the water.  2)Once in the cradle, drain the forward tank further.  3)Remove the front of the cabinets for access to the water tank - Drain it and blow it out with compressed air as a lot of water remains after draining. 4) Bypass the tank, connecting cold to hot. 4) Add two gallons of water to the front tank and pressurize the system -then blow out all faucets in the head, sink, rear shower and the high pressure water inlet 5) Pump antifreeze through the head, shower drain, and refrigerator drain. 6) put antifreeze in the sump and pump out with the electric bilge pump and also the manual whale pump. 7) I use a west marine Engine Winterizing kit to pump antifreeze through the engine. I mount it in the cockpit and run the line to the water strainer, then start the engine and watch for the exhaust water to run pink.  

Total antifreeze use is 5-6 gallons.  I think that Jeff Hare has a completely antifreeze free method using compressed air, but I have not tried that.

Hello
How many gallons of anti freeze should go in the holding tanks for winter. Is it best to drain hot water tank or let it fill with antifreeze.
