Well I went and done it. I just bought another LSS-1 to put on the trolling motor. Instaling it today. I am trying to make a bracket but will probably order one soon.
Transducershieldandsaver.com makes a very nice bracket for the LSS-1/ PD-WBL puck transducer to work together on the trolling motor. It isn't cheap but they custom build it to your trolling motor specs.
