Ultrex with Advanced GPS Navigation Features, Specifications and Manuals (does not include QUEST)(2023-present)

Step on the Ultrex™ foot pedal and feel what Power Steering does to a trolling motor. Then tap the Spot-Lock® button to stay on a fishing spot automatically. Only Ultrex combines the most responsive, intuitive steering ever with GPS-powered automatic boat control. The only thing we didn't do to it, is compromise. Select models now available with Built-In MEGA Side and Down Imaging® Sonar.


  • Part of the One-Boat Network
    Out of the box, Minn Kota motors come standard with everything you need to connect to select Humminbird fish finders, unlocking more advanced navigation features without needing to remember additional adapters or complicated set-up procedures.
  • Power Steering
    The most comfortable, responsive steering available. Ultrex's foot pedal is built for all-day ease, with precision control and instant responsiveness.
  • Steering Lock
    When you take your foot off Ultrex's foot pedal, the motor head remains pointed in the direction you left it. No recoil or readjustment, just easier steering every day.
  • Advanced GPS Trolling System The One-Boat Network gives you unprecedented control over your boat by linking your trolling motor to your Humminbird® fish finder. Control your trolling motor from the included remote or a connected Humminbird. You can set Spot-Locks, record paths, follow depth contours, automatically navigate to your favorite spots, control speed and steering, and more.
  • Spot-Lock with Jog
    Spot-Lock will hold you in place with unparalleled GPS accuracy. Spot-Lock gives you the power to stay right on top of any productive fishing spot, without touching your trolling motor. With the built-in heading sensor, you can use Jog to move your Spot-Lock location five feet in any direction.
  • Drift Mode
    Automatically engages speed and course control simultaneously, meaning anglers no longer need to depend on drift socks, kicker motors, or manual operation to control speed over water – even in the heaviest wind and current.
  • Lift-Assist
    Ultrex's patented Lift-Assist Design cuts the weight of stow and deploy in half. Features a stainless steel, nitrogen gas-charged spring.
  • Heel-Toe / Cable Foot Pedal
    It's the only foot pedal with Power Steering for all-day comfort and instant responsiveness — plus a button to activate Spot-Lock electronic anchor.
  • Digital Maximizer
    Provides up to 5 times longer run time on a single battery charge. These variable speed trolling motors let you dial in your exact speed, and they deliver only as much power as you need, helping to conserve your battery for a full day of fishing.
  • Indestructible Composite Shaft — Guaranteed for Life
    At the core of your Minn Kota trolling motor is an indestructible composite shaft. It's a Minn Kota exclusive, and we guarantee it for life.
  • Mobile App Compatibility
    Control your motor directly from your Apple® or Android™ device with the One-Boat Network app. You get quick command of speed, steering, Spot-Lock and AutoPilot — plus the ability to update software.
  • Available Transducers
    The Ultrex motors have a built-in transducer. The transducers available are the Built-in Dual Spectrum Chirp (DSC), and MEGA Side Imaging (MSI). To connect your transducer to a fish finder, you may need an Adapter Cable. The compatibility charts for the transducers listed at the bottom of this page will help you determine if your fish finder is compatible and if you need an adapter cable.
    • Built-In MEGA Down Imaging
      With a transducer built right into the motor, you get crystal clear Humminbird® MEGA Down Imaging and a clean protected look.
    • Built-In Dual Spectrum Chirp Sonar
      Keeps your transducer and wiring completely concealed and protected running everything through the trolling motor's shaft. By covering a wide range of frequencies, Humminbird's CHIRP produces more accurate, more detailed returns of fish, structure and the bottom than traditional sonar.


  • Available Thrust and Voltage Options
    The Ultrex is available in 80 lbs and 112 lbs. of thrust. The 80 lbs thrust motors are 24 volts. The 112 lbs thrust motors are 36 volts.
  • Available Shaft Lengths
    The Ultrex is available in shaft lengths of 45", 52", and 60". The shaft on the Ultrex cannot be lengthened as it would be cost prohibitive. The shaft can be shortened. If the shaft is shortened at an Authorized Service Center, it will not void your warranty. If the shaft is shortened outside of an Authorized Service Center, the warranty will be voided.
  • Motor Control Options
    The Ultrex is controlled with either a foot pedal or a handheld remote.
  • Mounting Holes
    All brushed Ultrexes have the same mounting hole patterns as our cable steer motors for easy interchangeability between new and older Ultrexes and upgrading from another cable steer motor to the Ultrex.
  • Shipping Weight
    The weight of the Ultrex can vary based on the options on the motor. The shipping weights are listed in the charts below.
