Mike, My idea was it is longer and hence a little more in the way, and it would cover my US2 up so I would have to mount sonar & Lss2 transducers on a bracket but then again that wouldnt be the end of the world. The only one I ever saw on a Trolling motor was the Lss 1 but I am sure there are some Lss 2s mounted there also. Just looking for others opinions and experiences that are more knowledgeable on this subject than me.Dan
