Humminbird AD-MTM-HW-MSI MEGA SI+ Trolling Motor Adapter Bracket

Upgrade your fishing setup with the Humminbird MEGA SI+ Trolling Motor Adapter Bracket, designed specifically to transform your transom-mounted MEGA Side Imaging+ transducer into a streamlined trolling motor mount. Anglers who chase bass in shallow waters or tournament pros scanning structure know the value of crystal-clear side imaging from the bow. This adapter hugs the trolling motor shaft for a sleek, low-drag profile, keeping your sonar data flowing without snags or interference during active retrieves.

Engineered for Seamless Performance

Crafted from tough composite materials built to battle sun, spray, and rough handling, this bracket ensures your high-resolution imaging stays rock-solid. No more wrestling with bulky mounts that catch lines or vibrate at speed—its form-fitting design minimizes turbulence and maximizes transducer contact with the water column for sharper MEGA SI+ images of fish-holding ledges, drop-offs, and weed edges.

Complete Kit for Quick Conversion

• Adapter Bracket: Precision-molded to conform perfectly to popular trolling motor shafts.
• Hose Clamps: Secure, rust-resistant fasteners for a vibration-free hold.
• In-Line Power Filter: Cleans up electrical noise for cleaner sonar returns and reliable performance on the water.

Everything you need arrives ready to install, saving you trips to the marine store and getting you back to targeting those trophy walleye or crappie faster.

Perfect Compatibility for Your Rig

This adapter pairs flawlessly with select MEGA SI+ transducers, unlocking forward-facing capabilities on your favorite Humminbird units. It supports:

• Transducers: XM 9 HW MSI T, XTM 9 HW MSI T, XM 14 HW MSI T, XTM 14 HW MSI T.
• Fish Finders: HELIX 8 CHIRP MEGA SI+ GPS G3N, HELIX 9 CHIRP MEGA SI+ GPS G3N, HELIX 10 CHIRP MEGA SI+ GPS G3N, HELIX 12 CHIRP MEGA SI+ GPS G3N, SOLIX 10 CHIRP MEGA SI+ GPS G2, SOLIX 12 CHIRP MEGA SI+ GPS G2, SOLIX 15 CHIRP MEGA SI+ GPS G2.

Verify your setup matches these specs for plug-and-play success—many anglers report spotting schools they missed from the transom alone.

Real-World Advantages on the Water

Picture this: You're idling over a point, and instead of guessing, MEGA SI+ reveals every branch and boulder in hyper-detailed color. The low-profile mount keeps your line clear during finesse presentations, while the power filter eliminates ghosting from motor electronics. Bass boats, multi-species rigs, or kayak setups all benefit from this simple swap, boosting your catch rates without a full transducer overhaul.

Pro Tips for Installation and Maintenance

1. Prep Your Motor: Clean the shaft thoroughly and position the transducer pod at shaft height for optimal water flow.
2. Secure with Clamps: Tighten hose clamps evenly—snug but not crushing—to handle waves and turns.
3. Wire It Up: Route cables along the shaft and add the in-line filter close to the head unit to squash interference.
4. Test Run: Dial in sensitivity on calm water, then push it in current to fine-tune imaging range.
5. Seasonal Care: Rinse with freshwater after saltwater trips; store dry to extend life through years of hard use.

Most installs take under 30 minutes with basic tools, letting you focus on what matters: finding fish.
