Re: Just how strong is 5200
No. 5200 is really more of a caulking material. it stays flexible even when cured and is not designed for structural applications. however you shouldn't be affraid to drill mounting harware into the floor of the boat, unless of course they would pass through the hull. in fact, that's really what 5200 is designed for. just fill the predrilled holes with 5200 then install the mounting screws and wipe away any excess 5200, then run a bead of 5200 around the base of the livewell along the floor and you should be ok. I suppose you could fiberglass it into place, if you wanted, but good solid STAINLESS STEEL screws sealed with 5200 should be plenty strong.
