Hi Dean. None of those questions are show stoppers.
Yes, it's cold out there.....Gonna need some rags in your sub to wipe the
windows with.
Hydraulics are good for control surfaces and many other exterior
devices.
Ambient trolling motors won't go that deep.
Electrical thru-hulls can be purchased, or hand built. It's not rocket
science. Just good glue.
I like the idea of a floating antenna. Never heard of one before......Good
idea.
Using any kind of glue to attach something to the outside is not gonna
work.
Weld a bracket, and bolt it on.
Good luck in your adventure, and remember to have fun......FRank
