I stopped messing with my lowrance cable/transducer on the trolling motor. I tore up cables twice and had to get replacement transducers. I bought a down rod mount that works for me (http://fishingspecialties.com/
). If you mount it strategically, it is out of the way and you will never have an issue with the trolling motor. The only issue is that when you deploy your trolling motor, you have to put your transducer down as well and vice versa on putting the trolling motor back up. If you would like to see my install (its better than the pics on the website), let me know and I will send a pic.
