I can't believe I can't figure this out. I am redoing the interior of my pontoon boat and everything is going well except for the drivers helm. I can't figure out how to separate the arm from the throttle box. (I don't know the technical term but its what you use to make the boat go forward/reverse.) I have loosened every visable screw/bolt I can see and it still won't come off. I have taken the cover of the interior (the part that is inside the helm) and I don't see bolt that would loosen the are. Please help!!
