The LiftSaver TM mount will be your best bet. Minn Kota does not offer/recommend using any slide mount for the Ulterra just in-case the motor is accidentally deployed while the mount is in the slide back position. It will hit the bow before fully deploying and by the time you loosen the thumb nut to slide the bracket forward damage could possibly occur. With the LiftSaver if the motor is accidentally deployed with the motor in the back position and hits the bow the pressure with either lift the motor up and into the normal position thus causing no damage.
