I have exsperianced the same thing? What I did on the knuckle that is on the front of your big motor, I used the same arm as you would use for a kicker motor, just made an 8 inch clevis from the trolling motor shaft to the arm of the big motor, and know I can control the trolling motor from my center counsel, just have to tweak the speed a little at times,
