I agree with George about the system 3 epoxy to seal any exposed wood.
I also agree with MOP about using a pick to check the condition of any wood. But I think I'd consider going further. Maybe a few 1/4" exploratory holes drilled around the drain plug area or the stringer to transom joint. If you're already doing glass work in the bilge it'll cost nothing to repair those little holes, and it'll give you some peace of mind to see dry shavings come off the drill bit.
