What is the proper procedure to attach a transducer mount to a fiberglass boat transom? I hate to be drilling holes in my transom. Also, from the bottom of my boat to the actual floor, there is about a five inch void, I'm assuming filled with foam. I don't think a screw would have any meat to catch on. I could actually fiberglass the mount to the boat, but was wondering wht the easiest and most correct method would be.
