Just did mine a few weeks ago. Here’s some advice that will make this relatively easy:
#1 Unscrew your foot pedal and straighten black housing that holds all of the cables out to where it is straight and no curves in it from foot pedal to motor head.
#2 Take a picture of how the cables wrap around the pulleys so that you don’t forget how they go back together. Take pictures of foot pedal and trolling motor head once you remove cover.
#3 BE SURE TO TIE SOME braided fishing line to your cable that you are pulling out of that black housing because you will want to use it to pull the new cable back though. (you will thank me for this…lol)
#4 Once it is all back together you will most likely have to adjust the tension of cables. You do this by loosening nut(s) at front of foot pedal.
I bet there are some youtube videos out there that will help. Irregardless, it is fairly easy to do. Just make sure you do #1 and #3 because they will save you a ton of headache. Good luck!
