Classic SeaCraft Community - Transom Delamination?

I am currently repowering my 23' SF inboard CC and was wondering about the lamination/delamination of the transom. First of all, we had the boat surveryed last fall when we purchased the boat and the surveryor said there was very minimal delaminaitn in the transom. This summer while working on it we noticed two things about the transom. One was that it did not seem that sturdy. We felt that the transom might not have been strong enough to bolt our fuel valves and racor to, thus we mounted it on smaller pieces of wood to the transom, making a little more sturdy. For instance when we pushed on the transom with our hand, with pretty good force, the transom seemed to flex a little.

The second thing we noticed was that when we looked up under the back railing, on the stern of the boat, we could see about a 1 inch gap between the top edge of the ply wood reincforcmenets on the transom and the railing, as if the ply wood wasn't made to go all the way to the top. We can even reach up under the rail and put our fingers on the top of the plywood and reach back to the bare hull (which i'm assuming, it may be the rail).

Is this normal for old potters or is this a feature of the SF inboards and not having to hold an outboard on the back? It says in the specs that the transom was reinforced with 1 3/8'' ply wood but I am not sure if this flexing is normal and whether that gap under the rail is something to fix. Either way, to me, it seems like the gap is only an entrance for water to get in and that the transom should not really flex at all. Should I be worried? If so, what do I do?
