Minn Kota Ulterra 112 72″ BT MEGA DI Sonar i-Pilot Link

The Minn Kota Ulterra 112 72″ BT MEGA DI Sonar i-Pilot Link is a premium freshwater bow-mount trolling motor designed for larger fishing boats that need extra shaft length, powerful thrust, integrated sonar and advanced GPS control. This configuration combines 112 lb of thrust, a 72-inch shaft, 36V operation, Built-In MEGA Down Imaging, Bluetooth-enabled i-Pilot Link, Spot-Lock, Auto Stow/Deploy and Power Trim.

The 72-inch shaft makes this version especially useful for compatible boats with higher bows or applications where a shorter 60-inch shaft may not keep the motor sufficiently submerged in rougher water. Minn Kota’s Ulterra platform supports 72-inch shaft configurations, while its 112 lb brushed models operate on 36V. (Minn Kota)

112 LB Thrust and 36V Performance

The Minn Kota Ulterra 112 72″ BT MEGA DI Sonar i-Pilot Link provides 112 pounds of maximum thrust from a 36V trolling-motor electrical system.

This additional power makes the 112 lb Ulterra a strong option for compatible larger freshwater fishing boats where an 80 lb motor may not provide the desired thrust.

Variable-speed operation allows anglers to make precise adjustments rather than relying only on fixed speed settings. Digital Maximizer manages motor output according to the selected speed, helping make more efficient use of available battery capacity during lower-speed operation.

Built-In MEGA Down Imaging

One of the biggest advantages of this configuration is Built-In MEGA Down Imaging. The sonar transducer is incorporated into the trolling motor’s lower unit, with the wiring routed through the motor rather than requiring a conventional externally mounted transducer and exposed cable.

Minn Kota says this arrangement provides sonar coverage directly below the bow while helping protect the transducer wiring from normal wear. (Minn Kota)

The system is intended for use with compatible Humminbird fish finders. Exact compatibility should be checked against the specific HELIX, SOLIX or APEX model being installed.

Bluetooth i-Pilot Link

The Bluetooth-enabled i-Pilot Link system adds advanced GPS control and integration between compatible Minn Kota trolling motors and Humminbird fish finders.

Minn Kota confirms that i-Pilot Link can be factory-installed on Ulterra and supports compatible Humminbird mapping products for functions such as Follow the Contour. (Minn Kota)

This gives anglers access to features such as GPS-assisted navigation, steering and speed control, while Spot-Lock can help maintain the boat at a chosen fishing position.

The Bluetooth-compatible Ulterra generation also supports communication with compatible devices and controls. Minn Kota’s documentation specifically identifies 2017–2023 i-Pilot and i-Pilot Link systems as Bluetooth compatible. (Minn Kota)

Auto Stow/Deploy and Power Trim

Ulterra’s signature feature is Auto Stow/Deploy. At the push of a supported control, the trolling motor can automatically lower into the water or return to its stowed position.

Power Trim provides electronic adjustment of trolling-motor depth without requiring the angler to manually reposition the shaft.

Minn Kota continues to identify Auto Stow/Deploy and Power Trim as defining Ulterra technologies. (Minn Kota)

Extra-Long 72-Inch Shaft

The 72-inch shaft distinguishes this model from more common 45- and 60-inch Ulterra configurations.

The additional length can help keep the lower unit at an effective operating depth on compatible boats with higher bows or in conditions where bow movement would otherwise bring a shorter motor closer to the surface.

Minn Kota’s compatibility documentation also specifically distinguishes 72-inch or longer Ulterra motors when identifying appropriate heavy-duty mounting accessories. (Minn Kota)

How to Use the Minn Kota Ulterra 112 72″

Mount the motor securely at the bow using hardware suitable for the 112 lb/72-inch configuration. Connect it to the manufacturer-specified 36V electrical system with appropriate marine wiring and circuit protection.

Once powered, use the wireless remote or supported control to activate Auto Stow/Deploy. Adjust motor depth with Power Trim, then control steering and variable speed through the remote or electric foot pedal.

Spot-Lock can be activated when GPS-assisted position holding is required. Connect the Built-In MEGA DI system to a compatible Humminbird fish finder using the manufacturer-specified connection hardware.

For model-specific installation and operation, use the official Minn Kota Ulterra and i-Pilot Link manuals.
