Going to be a hard freeze tonight. If you're like me, you don't completely winterize your boat and put it away for the winter. But we should do partial winterization to protect them. Run the pink antifreeze through all your fresh water lines. Drop your outboards down so all the water can drain out. Put some heat in your bilge if you can. This is not a complete list of things to as there are many different types of boats out there, just think through your situation and take some precautions.
