I have duel MC/Bravos that each has a neutral button that when pressed in forces the motor/OD into neutral so that I can advance the throttle w/o being in gear. I cannot press in or move one of the drives' button. The other one works fine. Since we had previously disconnected the OD's shifter linkage, to reinstall motors, I may have gotten something out of alignment. Before wasting a lot of time, should I be examining something else???
