Checked cable and cable seems to be OK. Disconnected cable and pushed lever all the way back on motor and still wouldn't go into reverse. Is there another adjustment that I could check
what year? I have a 1989 40hp. you can adjust the linkage to the lower unit, but you have to take the lower unit off and turn the linkage rod in or out. The adjustment I am referring to can't move unless you have the lower unit off. It is probably something internal causing your problem.
