Re: shift cable question alpha one gen.II
IF, you are using an OEM cable from Mercruiser, you do not need the special socket. Just unscrew that white plastic guide out of the cable end. Use a regular deep socket to install the cable. Then screw the white plastic guide back in.
NOTE: The reason I say it has to be an OEM cable is the cheap aftermarket cables are crimped on. Try to unscrew them, and you destroy the cable.
