TackleTour

I am a struggling to find a way to manage the slack line on my Terrova. It requires a good bit for all the rotation on spot lock and it can't be zip tied to the shaft like most trolling motors. I have seen where people run it up the grove on the shaft. My local authorized service center highly advised against that. He also said these motors weren't designed to have external transducers although I doubt many people use the built in USB one because it is sonar only. He said the best thing he had seen was an after market piece that mounted to the shaft and allowed the cable to pass through. It would have to slide up and down freely. He didn't know the name or where to find it. I can picture in my head what it looks like. Any ideas?
