here is an email Greg from Humminbird sent to me. I have my transducer mounted on my transom and not my trolling motor anyway.

Dave,
The transom (XHS) and trolling motor (XTM) versions of the HDSi transducer are exactly the same - same size, same insides, same cable. The hardware that gets shipped with one versus the other differs is different. The mounting hardware for both the XHS and XTM versions is available separately.

Now there is a true trolling motor Side Imaging transducer (no adapter brackets) but it has the same insides as the 797's CSi transducer. It is the same as the 797's CSi transducer but it is shaped for fitting on a trolling motor.

If I were you I would get the same mounting type as what you have now with your CSi transducer.
