Minn Kota Ultrex 112 Trolling Motor w/Micro Remote - Dual Spectrum CHIRP - 36V - 112LB - 52" — Product description

Experience Unmatched Control on the Water

Imagine gliding across the lake with effortless precision, holding your position over a school of fish without drifting, and steering your boat like it's an extension of your foot. The Minn Kota Ultrex 112 delivers that reality for serious anglers chasing bass, walleye, or pike in freshwater environments. This 52-inch shaft model packs 112 pounds of thrust on a 36-volt system, powering larger boats up to 28 feet through wind, current, and weeds without breaking a sweat.

What sets it apart isn't just raw power—it's the seamless blend of human intuition and cutting-edge tech. Anglers who've switched report catching more fish because they spend less time fighting the motor and more time casting. Whether you're tournament fishing or a weekend warrior, this trolling motor transforms how you navigate structure-rich waters.

Power Steering: Steering Redefined for All-Day Comfort

The heel-toe cable foot pedal feels like luxury compared to traditional setups. Power steering provides smooth, responsive control that mimics driving a car, eliminating arm strain during long sessions. Take your foot off the pedal, and Steering Lock keeps the head pointed exactly where you want—no annoying recoil or constant corrections.

Pro tip: Pair it with the included micro remote for hands-free adjustments when netting a big one or fighting wind gusts. This combo means you stay focused on the bite, not the boat.

GPS-Powered Features That Anchor Your Success

Spot-Lock acts like an electronic anchor, using GPS to hold your position within inches, even in choppy conditions. Add Jog functionality with the heading sensor to nudge your spot-lock five feet forward, backward, left, or right—perfect for dialing in over submerged humps or drop-offs.

The Advanced GPS system integrates with Humminbird fish finders via the One-Boat Network, letting you set waypoints, follow contours, or autopilot to saved spots. Mobile app control on your phone adds another layer, with speed tweaks, software updates, and Spot-Lock activation at your fingertips.

Integrated Dual Spectrum CHIRP Sonar: See More Fish, Catch More

Clean wiring runs through the shaft to a protected transducer, delivering crystal-clear sonar without deck clutter. Dual Spectrum CHIRP scans wide and narrow frequencies for detailed bottom structure, fish arches, and bait schools that traditional sonar misses.

Anglers love how it pairs with Humminbird units for real-time overlays, spotting crappie suspended mid-water or bass hugging timber. It's not just sonar; it's your unfair advantage in low-visibility water.

Built Tough for Rough Waters

The indestructible composite shaft flexes under impacts from logs or rocks but won't snap—backed by a lifetime guarantee. Lift-Assist makes stowing and deploying feel half the weight, thanks to the nitrogen-charged spring, ideal for solo launches.

Digital Maximizer tech squeezes up to five times more runtime from your batteries by optimizing power output. Variable speeds let you finesse presentations, from slow walleye drifts to quick bass repositioning, all while monitoring battery levels.

  • Weedless Wedge 2 Prop (MKP-38): Powers through thick vegetation without fouling.
  • Mono-arm Mount: Stable bow-mount design handles torque from high thrust.
  • 52-Amp Max Draw: Efficient even at full power.

Setup Tips for Peak Performance

Mount it on the bow of bass boats, pontoons, or multi-species rigs. Use the included stabilizer and hold-down strap for rock-solid security. Connect the 30-foot Ethernet cable to your Humminbird for full integration—store routes from dawn patrols or follow depth breaks effortlessly.

Maintenance is simple: Rinse after use, check props for nicks, and update firmware via app. Common upgrade? Add group 31 deep-cycle batteries in parallel for extended days without recharge worries.

Frequently Asked Questions

What makes Spot-Lock on the Ultrex 112 different from basic GPS anchors?

Spot-Lock uses advanced GPS with heading sensors for pinpoint accuracy, holding position within 3 feet against wind or current. The Jog feature lets you fine-tune by 5 feet in any direction without resetting, giving anglers precise control over hot spots.

Is the Minn Kota Ultrex 112 suitable for saltwater fishing?

This model is designed for freshwater use. For saltwater, consider Minn Kota's Terrova or Riptide series with corrosion-resistant coatings to handle the harsh environment.

What batteries do I need for the 36-volt Ultrex 112?

Three 12-volt deep-cycle marine batteries wired in series provide the 36 volts required. Opt for high-capacity group 27 or 31 batteries to maximize runtime, especially with sonar and GPS features engaged.

Can I control the Ultrex 112 from my Humminbird fish finder?

Yes, via the One-Boat Network. Connect using the Ethernet cable to compatible HELIX, SOLIX, or APEX models for seamless control of steering, speed, Spot-Lock, and navigation directly from your plotter screen.

How does the 52-inch shaft length perform on different boats?

The 52-inch shaft suits boats with 20-28 foot lengths and higher freeboards, like bass boats or walleye rigs. It keeps the prop submerged in rough water while minimizing drag when stowed.

Does the built-in CHIRP sonar work with non-Humminbird units?

The Dual Spectrum CHIRP outputs standard sonar signals compatible with most fish finders via the motor's networking capabilities. For full integration like MEGA Imaging, pair with Humminbird units.

What's the warranty coverage for the Ultrex 112?

It comes with a three-year warranty on the motor, plus a lifetime guarantee on the composite shaft against breakage. Register your unit for full coverage.

Ultrex 112 Trolling Motor with Micro Remote - Dual Spectrum CHIRP - 36V - 112LB - 52"

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 Minn Kota didn't do to it was compromise. 

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. Available on the pre-installed GPS system, Spot-Lock gives you the power to stay right on top of any productive fishing spot, without touching your trolling motor. With the included heading sensor, you can use Jog to move your Spot-Lock location five feet in any direction.

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 they guarantee it for life.

Built-In Dual Spectrum Chirp Sonar
