I've had some issues with going into reverse, it would grind and never really back up so I decided it was either out of adjustment, cable was stretched or problems with the reverse gearing so I adjusted the cable the other day and seemed to be able to get reverse good but for some reason I believe that it's not going into drive completely, kind of like it was slipping or something. My question is how do you tell if the cable is stretched? I have no problem replacing it but dont want to have to tear into the control if I dont have to? That brings up another question, how do you tell if the control is ok? Its a 650 Merc (76') and it runs so good i just want to sort out the reverse thing so I can get up to and away from the dock. Any help would be appreciated.
