I have a 1989 85HP Force and the steering is very hard to turn. I noticted that the previous owner had put tape on the cable which I haven't removed yet. Should I just replace the cable or should I try to grease it or something? If I replace the cable what kind of cable do I need, it's on a 30ft houseboat. How diffcult of a task is this? I have attached a picture of the cable with tape on it. Thanks in advance for any help.
