Garmin Trolling Motor Adapter Kit

The Garmin Trolling Motor Adapter Kit (MPN 010-11957-00) is a precision mounting solution designed to integrate Airmar TM150M CHIRP transducers with trolling motor installations. This adapter kit transforms a traditional transom mount configuration into a trolling motor-mounted sonar system, enabling anglers to place their transducer directly at the point of propulsion for superior target acquisition and real-time bottom tracking while underway.

The kit includes a plastic trolling motor adapter ring, plastic trolling motor adapter, metal band clamp, and stainless fasteners—all engineered to withstand saltwater exposure and repeated vibration from motor operation. The metal band clamp distributes clamping pressure evenly around the motor shaft, minimizing stress concentration that can lead to crack initiation. Mounting a CHIRP-capable transducer on the trolling motor instead of the transom eliminates dead zones near your primary propulsion and keeps sonar data synchronized with your actual fishing position, critical for shallow-water structure work and grass bed navigation.

This adapter is engineered for anglers running Garmin GPSMAP XS series chartplotters, GSD 25 Premium, or GSD 26 CHIRP sonar modules who rely on real-time bottom imaging for tournament success or consistent catch rates. Trolling motor mounting is standard practice in freshwater bass and pike tournaments, where the ability to hold position over deep structure while viewing sonar simultaneously justifies the hardware investment. Saltwater guide operations also benefit when deploying multiple trolling motors or when primary transducer mounting points are compromised by hull design constraints.

Compatibility is verified with plastic transom mount transducers and the Airmar TM150M 83/200 kHz CHIRP unit. The compact footprint (6 × 2 × 6 inches) and light weight (0.8 lbs) add minimal drag or steering resistance to electric motor assemblies. Installation takes under 15 minutes with common hand tools—no drilling, epoxy, or permanent modifications required.
