Don't be fooled, it's not a 20min job. It's not a hard job either, it jsut depends if the factory ran the steering cable thru the same zip-ties at the wiring loom to the rear of the boat.
I replaced mine a year ago, took about 1.5hours start to finish. I do say that pulling the one side of the tank up will help speed the job but should not be necessary.
Just buy the new cable from www.skidim.com
and you will see what goes where. If your handy with basic tools it should not be that hard for you.
