I am adding a jack plate to my boat and will need a longer cable. Anyone have a link to lowest prices or does anyone have a used  14' cable? Thanx a mill

Rickracer.com has cables.  I most cases, you can add a 6" plate and still use the existing cables.  You will need the number off your existing cable.

I added a jack plate last summer and had to replace my steering cable also & drill and extra hole in my transom. I will check what the old length was and get it posted. This was a rack & pinion. Typically you cannot obtain the required radius of mfg when extending your steering cable an extra 6".  This will generate excessive force required for turning and you will have rapid wear on the cable.

Thanx a lot for the response. I'll be adding it shortly and we will see what happens.
