David I can't remember if your engine is raw water cooled or not. If it is raw water cooled you have to get it hot enough for the thermostat to open in order to get the antifreeze mix around the block.
If its not raw water cooled then just a run through the pump, heat exchanger and exhaust will do the trick provided your engine coolant mixture in the block and tank is such that it won't freeze, again a 50/50 mix is about right for that. I always check the freezing point of my engine coolant before winter storage with a little float gage just to make sure. In either case, your muffler should be protected and not require draining and if your pump impellor is surrouned by the antifreeze mixture I think the ethylene glycol is just as good as vegetable oil: I use that same mixture to winterize my electric marine toilet too. It's about an hour of frustrating work to remove the impellor from my Sherwood pump, that's another reason why I have not changed it in the last 5 years.
