I have a 1997 20 Hp Mercury that I bought used on a zodiac. The Motor was setup with a remote shift/throttle assembly that I am not familar with and one of the cables has broken. The main shifter sends cables back to gear mounted where the hand held shifter/throttle handle would normally be. Then there is a smaller cable that goes into the motor and attaches to the shifter and throttle. This cable is broken and needs to be replaced. Does anyone know what this is called, where I can get diagrams and order the cables from? I think it is an add on item. Thanks for any help!
