This is what I know. HB you can mount the transducer on the trolling motor. I have one on my trolling motor. With no problems when you go in a some what strait-line. Not so good when you turn sharp or quick. Lowrance I hear you can't mount the transducers on the trolling motor. I was told because Lowrance uses 2 separate transducers with there units. But I don't know, I don't have a Lowrance. What I would do if I where you is call Lowrance customer service and ask them. If you can get them to answer the phone! LOL
