I am very lucky that I have the original documentation for my 94 CPMY. However, still a bit puzzled as to the winterization process. The book(s) say how many gallons of antifreeze to use, it is a ridiculous number! Mostly it states to dump somewhere in the neighborhood of 65 gallons of pink stuff into the storage tank and distribute to the different systems.Has anyone ever done this?:

Drain the water supply tank that is under the aft cabin bed

disconnect the tank water out line that goes to the pressure pump, use compressed air to allow the remaining water in the lines to be blown from the lines, opening all faucets one at a time to drain until spitting air.

disconnect and drain the water heater, use by pass hose if necessary, or connect the feed and supply lines together

take the pump supply line from the water storage tank and stick it into the gallon of pink antifreeze. Then turn on the pump and run each system as normal until the pure pink antifreeze comes out of each outlet.

Now, vacu flush toilets, flush each toilet using same procedure, until pink flows regularly into the bowl. Then dump and additional gallon or so through the toilet. Turn on waste pump until pink (well, brownish pink!) comes out the thru hull

dump pink stuff in each drain until it comes out the thru hull, and run shower drain pumps until pink stuff comes out

Dump a gallon of pink stuff into the outlet that is outside to hook pressurized marina water to, letting it flow to the storage tank

Open sea strainer to A/C and connect fresh water to A/C units and flush the salt water out. Then run units as I dump pink stuff into the feed lines until it is pumped out the thru hull.

Once at storage lot, open thru hull sea cocks and let any of the antifreeze back flow out through these devices.

By using the above system, I believe that I will get any standing water out of the lines and also have the protection of pink non toxic. Also will be easier to purge than just dumping the pink stuff into the storage tank. I am also going to take the inspection plate cover off of the storage tank and let it dry out, so perhaps I can clean the crud from the inside. I will also dump some pink tuff into the bilge where any standing water has accumulated even though it will be all pumped out.

ANY suggestions, feedback or comments will be welcomed!
