Garmin Trolling Motor Adapter Kit, For Airmar TM150M Transducer

Overview

The Garmin 010-11957-00 is a trolling motor adapter kit that lets you mount an Airmar TM150M transducer on a trolling motor. The kit uses a metal band clamp plus two 3/4 in. pan head screws to hold the adapter parts in place on the motor housing.

This is a mounting accessory, not an electrical converter, so it does not change how the transducer connects to your sonar. It is used when you want TM150M depth and temperature readings from a trolling motor location, with the transducer positioned to stay clear of the prop and steering motion.

Key features

• Made for mounting an Airmar TM150M transducer to a trolling motor lower unit using a band clamp style attachment.
• Adapter ring and adapter body help the TM150M sit properly against the curved surface of a trolling motor housing.
• Hardware size is defined for installation: two 3/4 in. pan head screws are included for fastening the adapter components.
• Supports TM150M installations used with compatible Garmin sonar setups, including GPSMAP xs series chartplotters and GSD 25 or GSD 26 sonar modules.
• Useful when routing the transducer cable up the trolling motor shaft to keep it controlled during deploy, stow, and steering.

What’s included

• Two 3/4 in. pan head screws
• Plastic trolling motor adapter ring
• Plastic trolling motor adapter
• Metal band clamp
• Installation instructions

Installation and setup

Dry-fit the adapter on the trolling motor first so you can confirm prop clearance and a clean cable path. Once positioned, the band clamp wraps the lower unit while the screw fasteners secure the adapter parts that hold the transducer.

After installation, turn the motor through its full steering range and cycle it through stow and deploy to confirm the transducer and cable do not contact the prop, skeg, lift mechanism, or bracket. Re-check clamp tension after the first trip, since vibration and temperature changes can let hardware settle.

Compatibility and fit

This kit is intended for the Airmar TM150M transducer form factor. If you are using a different transducer model, or a trolling motor housing shape that does not allow the clamp to sit flat and secure, this adapter may not be a match.

For the cleanest install, plan for strain relief at the transducer and at the top of the shaft, and leave enough slack for steering without creating a loop that can snag when the motor is stowed.

Electrical and sonar integration

Because this is a mounting kit, your wiring and connector stay the same as the TM150M transducer you are using. Confirm that your chartplotter or sonar module is compatible with the TM150M and that your cable routing keeps the connector dry and protected from pinch points.

Use cases on board

This setup is a good fit for boats that run a bow-mount trolling motor and want the transducer positioned with the motor for slow-speed work such as fishing structure or holding on a spot. It also helps when you prefer not to mount the TM150M on the transom due to trailer bunks, lifting strakes, or frequent shallow-water contact.

Maintenance and care

Rinse the clamp area after use and inspect for movement if you run in chop or heavy vegetation. A quick check of clamp tension and cable ties as part of routine boat prep helps keep the transducer aligned and protected over time.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
