I have a transom issue on my boat. It was starting to do this before I bought the boat, there is some type of substance that is sandwiched between the plywood and the skin of the boat. When it was wet it was soft and "gelatinous" and was expanding putting a bump on the transom. Now that it has dried it is hard and can be crumbled pretty easily. At this spot the plywood is in fine shape with no rot. My guess is it was a factory thing maybe to protect the plywood from rotting. Has anyone seen this before and know what it is ? I've looked through the forum and don't see any mention of it.
