Is there a big difference between the marine grade and A/C ply ? I can get the A/C for free.
Doesn't fiberglass have a tougher time adhering to marine ply ?
FYI: ( I don't know if this is useful, but ): Upon removal of the transom, the stringers connecting to the transom ( the foam filled ones ), and a 2.5' section of the 2x4 wood center 'keel' - I have noted the following:
The foam in the stringers seem to be closed cell. If there are voids in the foam, then sure water will seep. But, for the most part the water did not go any further. The wet areas of the stringers were near where the collected water near the scupper's weep into the bilge via a rubber hose. Poor design, but no big detriment to structure.
I also removed a section of the 2x4 center stringer ( to make room for an i/o ). This was in very good shape, although wet. Solid as a rock. I'm sure it would have rotted soon due to the wet. The water got in here via the small hole in the 2x4 that allows water to drain from side to side in the bilge.
Maybe some areas for you to check on your boats...
