I don't see any reason not to check the torque on the bolts. Only tighten, don't loosen.

I would not seal them with epoxy. They are wet with sea water. Sea water minus oxygen can do bad things to metal, even stainless.

I'd get a good bilge pump and keep her plugged into shore power or get a solar panel.
