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.

Features

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.

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.

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.

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
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.

Weedless Wedge™ 2 Prop
With swept-back flared blades to power through anything without battery-draining chopping and hacking, the Weedless Wedge™ 2 is one of the most trusted props in fishing.

Available Transducers
All Ultrexes include a built-in transducer. The transducers available are the Universal Sonar 2 (US2), MEGA Down Imaging (MDI), or MEGA Side Imaging (MSI). We do not off the freshwater Ulterras without a built-in transducer. 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.

i-Pilot and i-Pilot Link
The Ulterra comes with either i-Pilot or i-Pilot Link pre-installed. If your Ulterra has i-Pilot and you want to upgrade to i-Pilot Link, we have upgrade kits available (kits listed below). If you have i-Pilot Link, you may need an AS EC QDE Ethernet Adapter Cable. The i-Pilot Link Compatibility Chart will assist you in determining if you need the adapter. The manuals for i-Pilot and i-Pilot Link are linked at the bottom of this page.
i-Pilot and i-Pilot Link Upgrade Kits

Using the Ultrex with Lowrance and other Non-Humminbird Fish Finders
Ultrex motors equipped with i-Pilot operate independent of a fish finder. The i-Pilot remote works with the trolling motor, and provides features such as Spot-Lock, AutoPilot, Cruise Control and Record-A-Track. Because the system only connects to the motor and works independently of a fish finder, you do not need a Humminbird or any other finder to operate it. Only models equipped with i-Pilot Link have the ability to connect to a Humminbird fish finder to provide additional features than the GPS features listed above.

Battery Meter
The Ultrex comes with either i-Pilot Link or i-Pilot installed on the motor. The motor battery meter is displayed on the i-Pilot or i-Pilot Link remote control LCD screen. Please note, the trolling motor battery meter will only be displayed when the prop is not running. 

 

Specifications

Available Thrust and Voltage Options
Like the Ulterra, the Ultrex is available in 80 and 112 lbs of thrust and performs just as well as the Fortrex, Maxxum, and Edge motors. The 80lb thrust Ultrex is a 24 volt motor. The 112 lb thrust Ultrex is a 36 volt motor. We do not offer a 12 volt Ultrex.

Available Shaft Lengths
The Ultrex is available in shaft lengths of 45", 52", 60: and 72". 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.

Ultrex Foot Pedal Dimensions

Minn Kota has worked with the major boat manufacturers to ensure the Ultrex foot pedal will fit into the majority of all foot pedal wells. The dimensions of the Ultrex foot pedal are 12.5" long x 9" wide.

Mounting Holes
All Ultrexes have the same mounting hole patterns as our cable-steer motors for easy interchangeability between cable-steer trolling motors and upgrading from another cable-steer motor like the Fortrex to the Ultrex.
