Just purchased new unit and trying to figure out where to mount transducer. I have older fiberglass boat with stepped hull and also have jack plate. I had a 597ci HD di already on boat mounted on the outside transom and had alot of clutter and no accurate reading when runnig at higher rate of speed. Still clutter when idling. Wondering if where I had transducer mounted attributed to that but now question where do I put Side imaging transducer now. On bottom step where drains are or on jack plate. Moving my old one to my trolling motor. Any help and suggestions would be wonderful. Thanks fellas and happy fishing
