That is actually the only problem I am having right now. It is a U shaped piece of aluminum with two 1" (I think it is 1") square tubes welded on top then it has gussets to the front deck. It is all riveted on. The trolling motor is too heavy for it so I need to figure out some way to stiffen it up as the trolling motor wobbles back and forth in rough water. If you look at the second picture you can kind of see the gussets.
