OMC control box will not shift out of neutral unless I depress the ball bearing in back of shifter. No problems with it shifting from forward or reverse into neutral. It appears the ball bearing pops up a little higher when in neutral and lower while in gear. This disallows me to take it out of neutral without depressing it with a screwdriver. Is there something inside the box I may have worn out on the 04 johnson 115. If so can someone help me with a part number?
