It's all geometry. You can't change that.
The trim angles of drives have zero effect on the inner bar. It just moves left to right along with the steering arm/tiller. The center to center of the tiller arms do not vary. Thus the inner bar will ALWAYS attempt to maintain the drives in a parallel position. The outer bar has to allow for changes of angle.
Place a tape measure(your outer tie bar) on the floor, place the dummy end against a wall, extend tape out perpendicular to the wall and pinch it at 30". Now raise the dummy end 6" off the floor (just as trimming 1 drive out). Get back to me how much you need to 'pull' the wall in , (or make the tie bar grow) in order to make the wall contact the dummy end.
That's how much your drives will need to move in towards each other for the outer bar to connect to the drives freely, yet your inner bar is holding them at a set dim. Only reason it works is because you have wear/slop somewhere, or parts under stress until they wear in. Because a dealer installed one, makes him better at math than at geometry.
Ever hear of guys with triples that have the props contact each other when the center drive is trimmed up? Do the tape measure test for yourself.
