I'd think that answering which caulk to use someone has to put eyes on the situation. Is there a yard or marina person?
If the caulk needs to harden up I'd guess silicone would work. Other caulks generally stay soft and flexible. If it's deep then foam backer rod might be needed to fill the gap before caulking.
Or if its a gag between to immovable pieces epoxy and gel coat over.
If the screws need bedding I wouldn't bed fasteners w/o first potting the holes. No matter what you do it's likely that water will eventually get thru and potting keeps it from rotting the substrate.

Look up Tite-Seal.
Here's pictures of how butyl tape applies.

Thanks for the links. At least it will help me learn what questions to ask and some terminology. At my yard they don't do anything for free. A few years ago we had them tighten a belt that wouldn't stay tight for me. They ran the engine and ended up with 2 hours labor to check the entire engine while running. to add insult to injury, when we got back in the spring there was some water in the bilge and I asked if maybe the worker didn't make sure the strainer was tight when they put the water plug in to run the engine on the hard. He came out to the yard to tell me absolutely not, the water must be from another source. There was an additional 15 minutes labor charge at 120 per hour for that 15 minute answer. (which was very fishy since in all 21 years of ownership, that was the only time there was some water in the bilge.) I guess there are no easy straight answers, even with a pic of the current deteriorated caulk in the super zoomed pic. I've got some reading and studying to do.
