DelcoSol.
These are removable spacers which allow the tray to accommodate from a 24 series to a 31 series. One spacer for a 27 series and two spacers for a 24 series.
I am upgrading my cranking battery from a 29 series lead acid to a 31 AGM. My factory trays would not fit the larger battery so I ordered a new tray and went to install it tonight. I positioned the tray and proceded to drill the new holes when I drilled through the one hole water began to come out of the hole almost pressureized. It wasnt a huge amount maybe half a cup. The new holes are only about an inch from the old holes. My boat has not seen water since november. Could water somehow be getting trapped in the step area? If so, should I be worried about something rotting? Boat is a 2011 Puma AE with the crankning battery on the starboard side. There is no saddle tank on the starboard side. I did have issue with the drain on the compartment behind the drivers seat leaking. The drain fitting was not sealed properly. I removed the fitting and put new sealant on it and it seems to have fixed the problem but ocasionally I would have condensation on the under side of the lid even without rain.
31 series i mean
It depends on the brand battery though all 31 series should fit.
Nothing to rot. But water trapped under pressure is certainly not desirable. You are apparently drilling into two pretty large boxed areas that are foam encased in fiberglass. Id certainly try to see what is up with the water. It has to be coming from somewhere, and it has to get inside that foam flotation box somehow. Have you looked at the bottom of the boat, including above the bunks, to make sure you dont have any sort of nick, gouge, split, crack, or even very bad blisters? It is remotely possible that water slipped in during construction, and the expanding foam pressurized it.2008 Pantera Classic2014 Mercury Pro XS 200
I did look under the boat. Just a few minor scratches. Nothing Id say would even come close to letting water in. Its on the trailer so I cant check for blisters at the moment. It wasnt pressurized to the point that it was like a geyser from the hole. Just almost like hydrostatic pressure. Two things that were odd to me is that normally barring rain or really rough water my bilge is always bone dry, so I dont think its a lower hull leak. Second, why didnt water come out of the original tray screw holes when I removed them? It is only one inch left of the one that had the water coming out. Also, the other three new holes I drilled had no water coming out. Again, this was not a huge amount of water and it stopped after maybe 30 seconds. The box I was getting water in seems like its own molded box with no side access but maybe its possible that there are small holes under the carpet and the water was running from there to the battery shelf thats behind it?
Water can not enter the hull during manufacturing. There is no water associated to production. We are suspect to water intrusion through the floor, through a screw or bolt seal. The drain area should not be a position of water intrusion, internal leak yes, intrusion not likely. BCB
Is this something I should be concerned about? It wasnt much water and looking at the boat the bow was slightly elevated so maybe something ran back. Maybe the original screw went into a stringer and thats why no water came out? Sent from my iPhone using Tapatalk
Its nothing we can share opinion on as we dont know the condition or maintenance of the boat. Its like evaluating a transmission because it has a drip? Who knows without a thorough inspection.
My only advice is to NOT forget about it. Things that seem wrong usually are. And they will eventually go wrong enough that it will bite you. It sounds to me like the drill penetrated the foam box. What escapes me is why just that hole had the pressurized water, and not any of the others? The RTV around screws generally loses its seal when you remove the screw. So this one almost sounds like the boat needs an exorcism or something. Does your motor ever spin around multiple times and then spit tacks at you? BCB: Thats why I said “remotely possible”. I have been thru a couple of glass boat manufacturers facilities, and didnt remember any water, nor any way for water to be introduced, unless the roof had a leak (which I never saw).This is an odd one. Wouldnt have been so unusual if he had said “I drilled a hole and a little water dribbled out.” He said it came out under pressure. If he really meant “it sorta ran out a little faster than I expected” then perhaps simple head pressure caused by a leak higher up or closer to the front (if the nose is high) might explain it. But it would be minimal “pressure” if caused by gravity.Wish we could have seen it live…2008 Pantera Classic2014 Mercury Pro XS 200
Well just an update. Went and looked further into this. I took the shop air with a blow gun and blew through the holes. Water came out of each one. Maybe a half gallon before it was finally empty. I believe this issue was caused by the compartment leak behind the drivers seat I had. I removed the carpet from the box and saw that the box is a plastic bin glassed in. Along the top edge of the bin right under where the drain leaked theres a gap that the water most likely ran into. It would explain my constant condensation in the box even after I would dry it.

Floors and foam chambers are independently sealed and unassociated to storages with water. The bins are mounted on the deck, not in the hull and they are fiberglass.
So going on BCB explanation the only spot for water intrusion in this area, short of something being damaged, is the screws for the battery tray not being sealed?
