Humminbird AD-MTM-HW-MDI MEGA DI+ Trolling Motor Adapter Bracket Product Description

Upgrade Your Fishing Setup with the Humminbird MEGA DI+ Trolling Motor Adapter

Picture this: you're out on the water, chasing that perfect bass spot, but your transom-mounted transducer is dragging in weeds or getting bumped by docks. The Humminbird AD-MTM-HW-MDI adapter bracket changes the game by letting you relocate your MEGA Down Imaging+ transducer right onto your trolling motor. This smart piece of gear transforms your existing transom-mount unit into a streamlined, low-profile setup that hugs the motor's lower unit, keeping your sonar crystal clear without the hassle.

Crafted from tough composite plastic in a sleek black and silver finish, this adapter stands up to the rigors of daily fishing trips. It's designed specifically for trolling motors with 80-pound thrust or higher, ensuring a secure fit on popular models from Minn Kota and others. Plus, it comes complete with mounting hardware and an interference choke that tackles electrical noise from chargers and batteries, so your screen stays interference-free for those critical reads.

Key Features That Make a Real Difference on the Water

  • Seamless Conversion: Easily adapts XM 9 HW MDI T, XTM 9 HW MDI T, XM 14 HW MDI T, and XTM 14 HW MDI T transducers from transom to trolling motor mounting.
  • Noise Reduction: Built-in choke filter minimizes interference from onboard batteries and chargers, delivering sharper MEGA DI+ images even in choppy conditions.
  • Low-Profile Design: Conforms perfectly to the motor shaft, reducing drag and keeping your setup stealthy underwater.
  • Proven Durability: Rugged construction handles submersion, impacts, and UV exposure without cracking or fading.

Anglers love how this bracket unlocks the full potential of MEGA Down Imaging+, revealing fish-holding structures, bait schools, and bottom contours with incredible detail—right from your trolling motor's position for forward-facing precision.

Perfect Compatibility for Your Humminbird Ecosystem

This adapter pairs flawlessly with a range of Humminbird units, ensuring you're ready for any boat or fishing style. It's a go-to for:

  • HELIX 8/9/10/12/15 CHIRP MEGA DI+ GPS G3N and newer models
  • SOLIX G2 10/12/15-inch screens and all subsequent versions
  • APEX series across the board

Whether you're running a compact bow-mount setup on a kayak or a full-sized bass boat, this bracket fits trolling motors 80 lbs thrust and up, giving you consistent performance without custom fabrication.

Why Switch to a Trolling Motor Mount? Real-World Advantages

Moving your transducer to the trolling motor isn't just convenient—it's strategic. Here's why serious anglers make the switch:

  1. Cleaner Scans: Positioned ahead of the prop, it avoids turbulence and prop wash for undistorted down and side imaging.
  2. Less Vulnerability: No more trailering damage or beaching risks on the transom.
  3. Stealth Mode: Keeps your electronics hidden from prying eyes at busy ramps.
  4. Versatile Fishing: Ideal for shallow water, weed lines, and precise spot-locking with features like Spot-On and i-Pilot.

Users report spotting crappie beds and walleye humps they missed before, thanks to the elevated vantage point and MEGA DI+'s hyper-detailed resolution—up to 0.5-inch separation at boat speeds.

Simple Setup Tips for Peak Performance

Installation is straightforward with the included hose clamps, bracket, and power filter. Start by powering down your boat, then:

  • Align the bracket to the motor's lower unit curve for a snug fit.
  • Secure with clamps, routing the cable neatly to avoid snags.
  • Test the choke placement near the battery leads to squash any buzz.

Pro tip: In murky water, pair this with MEGA Live for real-time prey action. Regular freshwater rinses keep it corrosion-free, extending its reliable service.
