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

The Humminbird AD-MTM-HW-MSI MEGA SI+ Trolling Motor Adapter Bracket is a purpose-built transducer mounting solution that converts MEGA Side Imaging+ transom-mount transducers for trolling motor installation. Built with a rugged composite design, this bracket provides a low-profile fit that conforms securely to trolling motor arms without adding bulk or weight to your setup.

This adapter bracket is engineered to work with specific MEGA SI+ transducers, including the XM 9 HW MSI T, XTM 9 HW MSI T, XM 14 HW MSI T, and XTM 14 HW MSI T models, making it compatible with HELIX 8 CHIRP MEGA SI+ GPS G3N fish finder units. The composite construction resists corrosion in saltwater and freshwater environments while maintaining the structural integrity needed for secure transducer positioning. Weighing just 0.85 lbs, the bracket does not compromise trolling motor performance or battery runtime.

This accessory is essential for anglers who rely on side imaging sonar to locate structure and fish while operating a trolling motor. Whether fishing shallow lakes, river systems, or coastal flats, the MEGA SI+ transducer adapter allows you to maintain full sonar functionality without the complexity of installing a separate transom mount. The compact 7 x 4 x 9-inch footprint ensures the transducer stays clear of prop wash and obstructions common to shallow-water presentations.

Humminbird's MEGA Side Imaging technology delivers superior clarity and range compared to standard imaging modes, making the trolling motor mounting option particularly valuable for sight-fishing scenarios. This adapter bracket makes it practical to run MEGA SI+ systems on boats where transom-mounting is impractical or where anglers prefer the positioning flexibility of a trolling motor installation.
