This past summer, I noticed cracks in the ceiling of my cabin around the bolts for the mast step, with some indication of water coming in (see photos). There are no cracks in the deck surface and the deck still feels solid (no soft spots). I’m thinking that I need to remove the mast step, drill out the holes and fill with epoxy, then redrill the holes for the mast step and rebed it with butyl tape. I’ve read the Marine How To article on rebedding deck hardware with butyl tape (https://marinehowto.com/bed-it-tape/ ), which is very helpful. However, not having ever done this before, I’m apprehensive about taking on this project, so any advice or direction that you can provide would be helpful.
The compression post in the cabin appears sound, so I don’t think that I have to do anything with it. However, as you can see from the photos three of the nuts on mast step bolts are easily accessible, while the 4th is directly above the port bulkhead and cannot be accessed without cutting away or taking out the port bulkhead. Suggestions on the best method to access this nut would be appreciated.
On a related matter, the lifeline stanchion on the starboard side just forward of the mast is bent and I think is leaking into the cabin. I would like to rebed it also, but the inside plate for the stanchion is nowhere to be seen. Has anyone with an O’day 23 or similar boat rebed the stanchions and if so, how did you find the plate on the inside? I asked Rudy about this and he suggested attacking the inside with a Dremel tool.
Any advice that you can offer will be welcome.

Some other questions that I have are:
1) What diameter of bit should I use to drill out the holes for the mast step bolts?
2) What is the best type of bit for drilling fiberglass?
3) What is the best epoxy to refill the holes?1) What diameter of bit should I use to drill out the holes for the mast step bolts?
