I've revently winterized the head in my CC MKv.
I essentially just ran antifreeze through it - then threw in about a half litre of baby oil as recommended by Mason's. I also put some antifreeze in the holding tank.
I did not however pull out the drain at the bottom of the toilet.
When I went to the boat yesterday there was clear babyoil and water in the head - should I drain the head or is it fine the way it is.
Thanks in advance for your responses.
I'd just pump some more plumbing antifreeze through the system, making sure that there's some standing in the bowl. The baby oil is a nice idea, but you really don't want the toilet to freeze, do you?

I've read advice from the "Head Mistress", an accepted expert on marine head maintenance, that any type or amount of mineral oil is a very bad idea in the head. Since oil floats on water, oil in the holding tank covers the surface, eliminating most oxygen exchange with the contents, and virtually guaranteeing the growth of anaerobic bacteria next season along with the terrible stink these bacteria produce. You want as much air exchange with the holding tank contents as possible, to promote aerobic bacteria in preference to anaerobic, because aerobic bacteria will decompose ("compost") the waste without causing a bad smell. Some people install two holding tank vents, one at each end of the tank, to promote as much air exchange as possible, and some people even go so far as to install some forced ventilation in the tank. If you must use oil to lubricate the pump gaskets, one teaspoon of vegatable oil is a better choice.</SPAN>
I may be 'heading' into a problem some day (sorry, could not resist) - but . . .
All I do for winter is get a good pump-out of the holding tank, flush the system with plumber's antifreeze and then I use my handy shopvac and a ~4' piece of PVC tubing (connected via tape to the hose to stop air leaks) and suck out the holding tank via the deck after the boat is on the cradle. My reason for this last step is to remove any water/antifreeze mixture that may not stay liquid over our harsh winter weather.
This seems to work well and gets the tank nearly empty. Condensation in the tank by spring appears minimal.

On my MKV I pump the antifreeze through the head into the holding tasnk, then pull the drain plug at the base of the head. If the liquid drains out, no worry about it freezing.
