Boat Owners: My friend has a 2001; 20 ft Champion Bass boat and his back transducers came unglued from the inside fiberglass bottom of the boat. Does anyone out there know the process or procedure that is required to reseat these transducers? Things like: Fiberglass preparation, what type of epoxy to use and how to seat them properly. Any and all help would be greatly appreciated. Thanks in advance for all your help.
