I had to take mine off, what I found was they used long screws so you could get nuts on them and then tighten them up by keeping pressure on the control box. It also looks like there is 10 phillips screws holding the metal piece that the box is attached to, to the boat. You could remove the screws and see if it comes off. Then you have to get the screws holding the back plate off, mine were to tight to get off with the screwdriver I had out on the water, lol. Anyway I hope this helps, gl
