Winterizing a ZR6 closed cooled engine

Hey,
I got an 06 CC with the ZR6 closed cooled and am thinking of winterizing my boat by myself since there are no CC service areas around me. If the coolant/antifreeze checks out OK, do I just need to drain the exhaust side of things....or do I need to fog out the engine too? What's your method?

What does your owners manual say? I would think if you had antifreeze in the closed system, you would only have to drain the manifolds.

ya there is one plug you need to pull should be on the bottom back of motor where a group of hoses tee the only plug on a metal t back there pull it and you are good. the olny other thing i would make sure of is that there is no place where you ballast lines our pumps have a low spot in them where any water could stand and freeze
