Steering shot -aftermkt replacement

[sven]

Having some trouble getting the old cable out from the engine. i loosened the port side nut and i'm assuming i now have to loosen the starboard (larger size) nut. Is this correct? Does it then slip out? Boat is a 1986, I'm hoping removing the motor is not required. one more question: what size cable for the v20s? I looked all over the cable and helm and cannot find the size....I was assuming 17' or 18'

Thanks....if i didnt have this website, I wouldnt be boating this season!
