Re: steering cable replacement on 59 sports lido
You don't give too many particulars, so I will assume that your hull has drum and cable steering.
If so, then you need to buy aircraft type cable, plastic coated. be careful, because this cable is measured by the inside cable diameter, so if you need cable 1/4 inch, you need to ask for something smaller like 1/8 or 3/16.
You will need pulleys for all for corners of the boat and special clips to terminate the cable, plus springs to tension it and a special fitting for the engine.
Measure from the drum to one side and down the gunwale to the transom, then to the center of the hull. Now add from the center back to the corner of the transom. Do the same for the other side. Allow for about four turns on each side for the drum and allow a couple of feet more. Add all measurements to determine the amount of cable needed.
