Screws

Where my batteries are- between the gas tanks- found some screws that water got into the balsa core- essentially two screws that are used to hold the the plastic holder that the straps go through to hold the battery- drilled some pilot holes and pulled all the battery holder screws out and found my problem was localized to two screw holes- refilled all but the two wet screw holes and in the process of drying them out-

Thinking I would like not to re drill and instead get some plastic lumber or starboard and poxy them to the floor in the back bilge and then drill the plastic wood/starboard- anyone take that approach to avoid re drilling?

Ken,

I believe epoxying starwood blocks would hold battery hold down brackets.
Another method would be to fiberglass a small block of wood the the floor and screw into that.
Water intrusion in our CD's is a problem and needs to be checked up on as you are doing.

I don't know, (don't think), you can epoxy starboard. BUT I do know you can epoxy wood. that is what I am doing right now in moving my Racor filters. they were screwed into the transom, under the splash well, and when I removed them, I am filling those holes and then have some wood, (was looking for teak, but a C-Brat friend had some purple heart that I am going to glue to the transom, and then drill and mount my filters into the wood. Had to do all that, just to put in a new bilge pump.

A couple of thoughts:

1) Epoxy/glass a couple of short pieces of fiberglass angle to the deck and then use those to anchor to. One place to get the pre-formed angle is McMaster-Carr.

1a) I wonder if VHB tape would work for the angles instead of epoxy/glass (this is something I've been reading up on and experimenting with for some things but am not yet qualified to "officially" suggest). But it could be a good use.

2) Another thing I've been wanting to experiment with is Weld-Mount fasteners. They are essentially various fastener bases that "glue" to the substrate with methacrylate. They are being used quite a bit in new boatbuilding to hold various pieces of equipment (fuel filters, etc.). without penetrating cored/thin structures. I'm not sure if they would be appropriate for batteries, but that could be checked.

3) On the other hand, if you were to remove all of the damp core, then prep and put in a wide epoxy annulus, re-screwing into the bottom would be very unlikely to cause a future problem, if you decide to go that way.

I wouldn't choose starboard. It does not take sealants well, can creep under load, and (minor cosmetic point) in the light colors it gets dirty and is not easy to clean.
 
A friend - boater- tells me he used stainless steel battery posts and used "5200" to attach them to his fiberglass floor and has held for a year- spoke with a sales person at West Marine who seems to think it would work- sounds simple- anyone ever "here tell" of anything like this as a way of Holding batteries in place??

Thanks for the advise.

AKA the"things" that the straps go through to hold the batteries in place. The "thing" I am trying to avoid screwing to the floor of the back bilge-sorry for not being as clear as I should have been- I am sure your question made my post clearer for everyone else.

Thanks
