Can someone please let me knoe how to take the shifting cable off of a 120hp Mercruiser Bravo (1978)? I have the lower unit off to fix something else and I also need to replace he shifting cable, the one from the motor to the lower unit. I see the upper part which looks easy to take off but I followed the other end as far as I could and came to a spiraled piece of metal around the cable. That's as far as I got.
