It can be done.
You’re in luck, just finished the exact same job on H260 05. You can take the cables out first and measure them to be sure. Ours were replaced with Universal TFXTREME 3300 Premium cables- CCX633 Series. They were from Defender Marine 10’ long model CCX63310 $37.99, many places have them. The motor ends are put on the new cable as well as the pedestal yokes.
Replacing them is a real experience. Edson engineering as far as replacement is not too elegant. You get the directions at the Edson web site” How to change engine control cables on your Edson Pedestal” When I first read them I thought, you must be kidding, I have to go through all that, just to get the cables out. There must be a simple way. Not. Follow the directions exactly and it actually works. You must go as far as loosening the chain and moving it forward. I additionally marked the chain location on the sprocket to put it back in the same place. I also had a messenger line on both yokes to help guide them to port. Good luck.
