I have read all the great info on this forum on winterizing and I have serviced everything as instructed i.e. fuel filters, engine oil, fuel treatment, gear oil; drained water from block (2 drain plugs) after thermostat had opened. I have never had to winterize coming from the deep south so this is my first time. I understand that air can?t freeze but I succumbed to pressure from other boaters in the area and I poured the pink antifreeze in, I removed the thermostat and added it until I saw pink antifreeze at the bottom of the housing. I also poured it in until I had antifreeze coming out of the exhaust drain plug. So my question by added the antifreeze the way I did the odds that I have an engine full of pink antifreeze is good? I maybe just panicking and have nothing to worry about or do I just go out and drain it out and go with the theory air doesn?t freeze. I know this is stupid just want to sleep at night, and also want to hear what people think?.
