Well everything I saw on the web about running your transducer cable down trolling motor when I got my xi5 was to get a air line (the type that stays in its coiled shape) and make slit in the side down the length of it. Than insert the transducer cable, this gives cable some protection while also keeping it in order. Than just wrap around shaft a couple times and than mount transducer. You won't need all the air hose,and you only need a couple coils around shaft to get job done. This is dependent on how long of shaft you went with and were you run your depth collar. hope this helps.
