Bought this little unit to put on my bow of the boat but having a hard time finding the right trolling motor bracket to mount this. Anyone have this unit on your trolling motor and if so do you know what model bracket you used?

The proper installation is a transducer that is made for a trolling motor application. It has extra internal shielding to help with possible RFI issues.

The worst you can do is adapt the transom transducer with this:
There are similar ones made by several companies.
