i have a 1996 vovlo 7.4 with a dp...i am trying to pass the shift cable through the rubber hose at the transom but it wont push through to go to the drive...tried to use a fish wire and pushed it into the inside of the boat and then taped the shift cable to the fish wire but everytime it gets right to the transom it sticks and tears off....anyone have any tricks to make this more simple?
