This was a water cavity that could not drain that consequently froze and broke .There is a small drain hole about the 7:00 position from the fracture that plugged up and could not drain any residual water . The piece of aluminum should be near by the fracture if this happened recently
Between this and your other thread http://forums.iboats.com/showthread.php?t=525029 unless you have a lot of money to sink into that old a boat, it's time to run away.
Drives junk, transom shield is junk, Engine? rest of the boat? Trim system? Electrical? Wood rot in transom and stringers?
You better have a lot of reasons to want that particular 67 boat to ever be worth the money it's about to cost you.
I could spend $10,000 on a much better one but I wouldn't get the enjoyment of fixing my own.
Since I don't have that part that fell What can I do?
Im pretty sure I could part the boat out and sell the trailer separately and make $500
