I have a 2012 X45 Closed Cooling in South Louisiana. We havent really ad any hard freezes yet but im trying to decide if i need to winterize or not? I dont live right by where the boat is stored.
Do I even need to winterize a closed Cooling Syetem? If antifreeze is in the block and stuff that would have a lower frrezing point than a non closed cooling. Anyone have advice for this
