The transducer in the picture is from my 788 which is getting bumped up front. So no, the only transducer will be the SI transducer. I am going to bump the transducer as far to the right (starboard) as I can and have the bottom left edge of the transducer 1/8" below the transom line so that the bottom right edge is 1/4" may be a little more due to the angle below the transom line.
Thank you for your time and advice, I greatly appreciate it!
