I have an 1983 vintage 37 with the plywood lids.
I have had leaks from the inspection ports, and I went in search of the rubber seals for the screw in deck plates (I thought they were "O" rings, but they are actually triangle cross section and referred to as "gaskets" by the manufacturer). My deck plates are made be Beckson.
On the Beckson web site I found the gaskets, but I also found their clearance section where they had the whole deck plate for not much more than the gasket. So I bought 4 new deck plates and I intend to replace the existing ones and add an extra one in each tank to aid cleaning.
The last time I checked, the plywood seemed to be in good shape. The screws that hold down the lid in the V berth, are partially cover by the interior cabinetry, so I don't know how you get them out?
The other problem I have had is when both tanks are full. The bow tank is higher than the stern tank, so if you turn them both on the water drains toward the stern tank and fills it, then applies static pressure to the seals which causes them to leak. Now I make sure only one tank is turned on at a time.
