I contacted Grady White, I was told that these brackets were made by Gil, when the boat was manuafactured the bracket had the threaded rods screwed into the bracket and a bolt put on then 5200 was applied to the bracket and rods then the bracket and the rods were installed into the transom as one piece, then the bolts were tightened on the transom side. For those of you thinking of trying to take this bracket off I would highly advise against it. Even after applying heat to the rods and using an air hammer I could not get them to budge. I will get the bracket painted while on the boat and apply 5200 around the edges of the bracket. I wanted to do the job right and make sure the bracket is re-sealed correctly but its an incredibly difficult job to do.
