Rick, Is this a trick question?
Anti-freeze is only effective when mixed in a 50% solution with water. It's of course, used in the closed fresh water cooling section; but during winter layup, I prefer to run it through the raw water section as well.
As you clearly pointed out in your previous post, sea water does freeze and there's no assurance all can be drained from the system. The anti-corrosion additives also help protect the c.i. engine components from rusting.
