I have an Ultrex with an external transducer mounted to it (mega). I love the motor and have had zero troubles with routing the transducer cable. Just leave enough loop at top of shaft to allow it to rotate to each directions limit, same as a regular cable steer. I have seen several report that they have routed the transducer cable down the wiring jacket to the foot pedal without the usual interference issues, but I did not try it. I ran my cable down the mount with no issues so far after a year.
