Have a 1987 OMC IO 130hp, the shift lever binds while trying to shift back to nuetral from either gear, seems to be worse while engine is running. I sometimes have to kill the engine to get it back to nuetral. The lower unit was recently taken off by the guy I bought it from to replace the main drive bearings that had locked up while I was testing it the first time, not sure why that would have anything to do with it. Just wondering were to start for adjustment of the controls almost seems like the lever is binding or a cable. Any Ideas where to start??????
