I have a 1986 alpha sterndrive. I'm in the process of replacing the lower shift cable. I have the latest number from quicksilver. I downloaded the manual from the adult section. It says to install the cable thru the alum shift fork.tighten the allen head screw just so it touches the cable end and u should still be able to turn the cable in the shifter. This cable when i feed it thru the shift it Appears to lock in place. Is this normal?
