Minn Kota Ultrex Combo 80 52″ MDI and Micro Remote

The Minn Kota Ultrex Combo 80 52″ MDI and Micro Remote is a premium freshwater bow-mount trolling motor built for anglers who want cable-steer responsiveness combined with advanced GPS control and integrated Humminbird imaging. It combines 80 lb of thrust, 24V operation, a 52-inch shaft, Built-In MEGA Down Imaging (MDI), Power Steering, Spot-Lock and a wireless Micro Remote.

This configuration is particularly well suited to compatible bass boats and freshwater fishing boats where a 52-inch shaft provides the additional depth needed compared with the shorter 45-inch Ultrex.

For current manufacturer information, see the official Minn Kota Ultrex product page.

80 LB Thrust with 24V Performance

The Minn Kota Ultrex Combo 80 52″ MDI and Micro Remote delivers 80 pounds of maximum thrust using a manufacturer-specified 24V trolling-motor electrical system.

This provides strong trolling performance without requiring the 36V electrical system used by 112 lb Ultrex models.

The variable-speed motor allows precise adjustments according to wind, current and fishing conditions. Digital Maximizer manages motor output according to the selected speed, helping conserve available battery capacity when maximum thrust isn’t necessary.

For general information about this type of marine propulsion, see the Wikipedia overview of trolling motors.

Built-In MEGA Down Imaging

The MDI designation means the trolling motor features Built-In MEGA Down Imaging.

Rather than attaching a separate imaging transducer to the motor and routing an exposed cable down its shaft, Minn Kota integrates the sonar transducer into the trolling motor’s lower unit.

When connected to compatible Humminbird fish finders, MEGA Down Imaging provides detailed imaging beneath the bow, helping anglers examine fish, vegetation, submerged structure, drop-offs and bottom composition.

Minn Kota’s Built-In MEGA Imaging system also provides applicable Dual Spectrum CHIRP 2D sonar through compatible Humminbird electronics.

Fish-finder compatibility varies by model and generation, so verify your electronics through the official Minn Kota Built-In MEGA Imaging compatibility guide.

MDI vs. DSC

The sonar package is one of the biggest differences between Ultrex configurations.

DSC — Dual Spectrum CHIRP focuses on high-quality traditional 2D CHIRP sonar.

MDI — MEGA Down Imaging adds high-detail imaging beneath the boat while also supporting applicable Dual Spectrum CHIRP functionality through compatible Humminbird equipment.

For anglers who want more detailed underwater imaging directly beneath the bow, the Minn Kota Ultrex Combo 80 52″ MDI and Micro Remote provides the more advanced integrated sonar option.

Power Steering with Cable-Steer Control

Ultrex is designed to combine the response of a traditional cable-steer motor with Power Steering.

The heel-toe foot pedal gives anglers immediate directional control while electronic assistance reduces the effort required to steer.

Ultrex also features Steering Lock. When the angler removes their foot from the pedal, the motor stays pointed in the selected direction rather than automatically recoiling.

This combination is particularly useful for anglers who spend long periods casting from the bow and prefer controlling their trolling motor primarily by foot.

Spot-Lock and Advanced GPS

The Minn Kota Ultrex Combo 80 52″ MDI and Micro Remote incorporates Minn Kota’s advanced GPS trolling technology.

Spot-Lock uses GPS to help maintain the boat at a selected fishing location, reducing the need for constant manual corrections.

With the appropriate heading sensor, Spot-Lock with Jog allows anglers to shift their selected position in small increments.

Supported GPS functions also include AutoPilot and additional navigation capabilities through compatible equipment.

One-Boat Network Integration

Ultrex is compatible with Minn Kota and Humminbird’s One-Boat Network.

When connected to compatible Humminbird fish finders, supported features allow the trolling motor, sonar, mapping and navigation equipment to work together as an integrated fishing system.

For anglers already using Humminbird electronics, combining MEGA Down Imaging with One-Boat Network connectivity can create a streamlined bow electronics setup.

Wireless Micro Remote

The included Micro Remote provides compact wireless control of supported trolling-motor functions.

The heel-toe pedal remains available for direct cable-steer control, while the Micro Remote gives the angler another way to access important motor functions when moving around the boat.

Its compact design also makes it convenient to carry on a lanyard.

52-Inch Composite Shaft

The 52-inch shaft provides seven inches of additional reach compared with a 45-inch Ultrex.

This can benefit compatible boats with a greater bow-to-waterline measurement or anglers who regularly fish in conditions where bow movement makes a shorter trolling motor more likely to approach the surface.

Correct shaft length should be selected according to boat dimensions, mounting position, load and normal fishing conditions.

How to Use the Minn Kota Ultrex 80 52″ MDI

Securely mount the trolling motor at the bow according to Minn Kota’s instructions for the exact model. Use the manufacturer-specified 24V electrical configuration, appropriate marine-grade components and required circuit protection.

Use Lift-Assist when manually deploying or stowing the motor. Once deployed, the heel-toe foot pedal controls direction and variable speed.

Use the Micro Remote for supported wireless controls and activate Spot-Lock whenever GPS-assisted position holding is desired.

Connect the integrated MEGA Down Imaging transducer to compatible Humminbird electronics using the manufacturer-specified connection or adapter.

For detailed setup and operating information, consult the official Minn Kota Ultrex manuals and installation guides.
