Humminbird AD XTM 9 Trolling Motor Adapter f/XNT Transducers Product Description

Upgrade your fishing setup with the Humminbird AD XTM 9 Trolling Motor Adapter, a game-changer for anglers who demand precision and reliability on the water. This silver adapter transforms standard transom-mount XNT transducers into a seamless trolling motor mount, positioning your sonar exactly where you need it—right at the bow for optimal forward-facing coverage. Whether you're chasing bass in shallow coves or tracking walleye in deeper waters, this mount keeps your electronics stable and clear of boat clutter, enhancing your ability to spot structure, fish, and bait with unmatched clarity.

Why Anglers Rely on the AD XTM 9 Adapter

Built to withstand the relentless pounding of waves, spray, and rough handling, this adapter embodies Humminbird's commitment to rugged marine gear. It eliminates the hassle of dangling cables and awkward positioning, giving you a cleaner deck and better performance. Key advantages include:

  • Effortless Transducer Relocation: Easily shift your XNT series transducers from the transom to the trolling motor, ideal for bow-mounted fish finders.
  • Superior Sonar Positioning: Forward placement improves downrigger and live scope readings, helping you pinpoint fish-holding spots faster.
  • Durable Construction: Crafted in the USA with corrosion-resistant materials that stand up to saltwater, freshwater, and everything in between.
  • Universal Fit for XNT 9 Series: Perfect match for popular models like XNT 9 20 T, XNT 9 DI T, and more, ensuring plug-and-play simplicity.
  • Peace of Mind: Backed by a solid warranty, so you can focus on fishing, not fixes.

Anglers report fewer false readings and quicker target acquisition, turning average outings into trophy hunts. It's not just hardware—it's a strategic edge.

Extensive Compatibility for Your Humminbird Setup

This adapter pairs flawlessly with a wide array of XNT 9 transducers, including XM 9 MDI T, XNT 9 20, XNT 9 20 T, XNT 9 DB 74 T, XNT 9 DI T, XNT 9 HW DI T, and HW MDI 75 T. It also supports mounting on trolling motors for dozens of Humminbird units across classic and modern lines.

Compatible with legacy favorites like the 300-series (323, 325, 343C), 500-series (515 through 597ci HD DI), 700/800-series (717 to 798ci HD SI), and 900-series (917C, 957c). Matrix models from 10 to 97, plus the entire PiranhaMax family (1 through 240), all work seamlessly. Whether you're running a compact PiranhaMax for kayak fishing or a feature-packed 859c for tournament bass boats, this adapter integrates without compromise.

Pro Tip: Double-check your transducer model against the full list to ensure a perfect fit—most XNT 9 transom-mounts are covered.

Simple Installation for Quick Setup

Getting your transducer trolling-motor ready takes minutes with basic tools. Start by securing the adapter bracket to your motor's shaft using the included hardware—typically two bolts and a clamp for rock-solid hold. Align the transducer's mounting holes, thread in the screws, and route the cable neatly along the shaft with zip ties. Adjust the angle for optimal water flow over the face, avoiding cavitation zones near props.

  1. Remove transducer from transom.
  2. Attach adapter base to trolling motor (universal fit for most Minn Kota and similar models).
  3. Mount transducer to adapter arm.
  4. Secure cable and test in water.

No drilling required on most setups, and it's reversible for multi-boat use. For best results, apply marine sealant to threads in saltwater environments.

Long-Lasting Performance with Easy Care

To maximize lifespan, rinse the adapter with fresh water after every trip, especially in brackish areas. Inspect bolts for tightness before launches and lubricate with silicone grease annually. This simple routine prevents corrosion and ensures consistent sonar data. Pair it with Humminbird's high-definition transducers for side imaging, down imaging, or 2D sonar that reveals hidden gems others miss.
