Hello all, I have my 91 Gulfstream at the shop for a bracket change. The bracket constantly filled with water and it appears to have porous areas due to galvanic corrosion. The mechanics are having a problem removing the bottom bolts on the bracket. They feel they are standard bolts with nuts but cannot find the nuts on the inside of the transom. They are thinking they might be in the stringer boxes?? Have anyone else run into this on a bracket removal? Any info would be of great assitance. TIA
