I measured my boat exactly as shown in the diagram FOUR TIMES. Each time it came out to 12ft 6". So as recommended I rounded it up and ordered the 13ft cable. Way too long boys! So I measured the cable I removed as the diagram shows, and it came out to 10ft 8". A 11ft cable is not offered and a 12ft will still be too long so I'm going to have to order the 10 footer and hope I can get it to work. I hope it does cause it really is an easy replacement and good quality item.
