Through-hulls closed in winter?

One of my (many) off-season projects will be replacing the old gate valves in my hull with properly bedded Forespar Marelon seacocks. I have read that you want to keep all seacocks closed in the winter except the cockpit drains, but I'm not 100% sure about the underlying theories.

What I would like to do is start removing the gate valves and through hulls now, prepping the surfaces as I go. If I do that, there's a very good chance that cold weather will set in during the project and I won't be able to finish bedding the new fixtures until spring. Of course, I can grind the hull in any weather. It's just the epoxy / bedding compound curing that concerns me.

The boat is on a cradle right now in New York, so real cold weather is approaching. Would having a few through hulls missing over winter be such a problem that I ought to wait until warmer weather or is it no big deal to start now and finish later?

We must find the person who installed gate valves in your boat and feed him to the lions. It is our duty.
