Get good cables
I got the Tfxtreme 3300 CC cables from West Marine, part number 1165315, 10 foot cable. What a difference from the original cables! These are worth the extra money. The are so smooth. I would replace both the shift and throttle cables. I replaced the shift one year and had to replace the throttle the next year. As posted above you can find instructions to replace the cables on the Edson web site. If you have problems, post them here.
