4 Best Trolling Motor Fish Finder Mounts for Boats in 2026

Updated November 2026

Anyone who has tried to run a trolling motor fish finder mount setup on a bass boat, jon boat or kayak knows the problem: the transducer has to sit in clean, moving water, stay locked in place, and still let you reach the controls without fighting cables. A good trolling motor fish finder mount solves that. This guide compares four options, and we judged each one on compatibility with common sonar units and trolling motors, mounting method, build material, and the kind of owner feedback that tends to show up after months of use.

JERBOR Upgraded Transducer Mounting Plate

Best for: Lowrance 3-in-1 Active Imaging transducers mounted to a Minn Kota-style trolling motor

This plate is built for anglers who run a Lowrance 3-in-1 Active Imaging transducer and want to bridge it onto a trolling motor. The ABS construction keeps weight low and resists water exposure.

Key specs

• ABS plastic construction
• Waterproof design intended for trolling motor transducer mounting
• Listed fit for Lowrance and Minn Kota setups

Pros

• Lightweight ABS keeps added load on the motor shaft minimal
• Specifically aimed at Active Imaging 3-in-1 transducers
• Plate format gives a stable, flat mounting surface

Cons

• Narrow compatibility outside Lowrance 3-in-1 setups
• Plastic plates can flex under heavy trolling speeds, so check torque on fasteners

Bottom line: A strong fit for Lowrance Active Imaging owners who want a dedicated plate for trolling motor use.

Transducer Mount for Lowrance 3-in-1 Active Imaging to Minn Kota

Best for: Budget-minded anglers with a Lowrance 3-in-1 transducer and a Minn Kota trolling motor

This mount targets the same Lowrance-to-Minn Kota pairing as the plate above, with a focus on durability and simple installation. It is a practical pick for anglers who want a straightforward bridge without extra features.

Key specs

• Industrial-grade ABS construction
• Waterproof and impact-resistant
• Designed for long-term use and easy installation

Pros

• Impact-resistant build suits rough launches and trailer hauls
• Straightforward installation with basic tools

Buying Guide

Mounting Method: Track, Shaft or Bracket

Decide how the mount attaches before anything else. Track-mounted arms, like the WINDFRD unit, need an existing track on the boat. Shaft and motor-mounted plates attach directly to the trolling motor. Measure your gunwale or bow deck before buying so you know which system you can use.

Compatibility with Your Sonar Unit and Transducer

Check the transducer model and its connector or mounting footprint. Lowrance 3-in-1 Active Imaging transducers have a different geometry than standard transducers. Match the mount to your transducer brand and model, and confirm the trolling motor brand too.

Trolling Motor Brand and Shaft Fit

Trolling motors vary in shaft diameter and mounting bracket style. A mount designed for one brand may not clamp correctly on another. Look for a listing that names your motor brand, and check the manufacturer’s fitment chart before buying.

Material and Waterproofing

Most mounts use ABS plastic, aluminum or stainless hardware. ABS resists corrosion and keeps weight low, which matters on small craft. Stainless fasteners reduce galvanic corrosion in saltwater. Choose materials rated for marine use, especially if you fish saltwater.

Vibration and Stability at Speed

A transducer that wobbles will produce noisy sonar returns. Pay attention to how the arm locks down and how many contact points the mount uses. Retighten fasteners after the first few outings, since vibration can loosen them over time.

Use Case: Boat, Kayak or Jon Boat

Kayak anglers usually need a lighter, more compact setup with clamp or track mounting. Larger boats can handle a heavier arm. Jon boats often have limited mounting real estate, so measure the transom or bow before choosing. Match the mount to where you actually fish.

Installation and Care

Plan the transducer position so it sits in clean water, away from the motor prop wash and hull strakes. Check fastener torque regularly, rinse the mount after saltwater trips, and inspect cables for chafing. Owners often report that a quick fresh-water rinse after each trip extends hardware life.

FAQ

What is a trolling motor fish finder mount?

It is a bracket or plate that holds a sonar transducer on or near a trolling motor, so the transducer sits in water and can read fish and bottom structure while you troll or hold position.

Can I mount a fish finder transducer on any trolling motor?

Not always. Compatibility depends on the trolling motor brand, shaft diameter and bracket style, plus the transducer model. Check the manufacturer’s fitment information before buying.

Is a track mount better than a motor mount?

Neither is better in all cases. A track mount offers flexibility and needs no drilling if your boat already has tracks. A motor mount keeps the transducer close to the trolling motor, which can give a cleaner view when the motor is deployed.

Do I need stainless hardware for saltwater use?

Stainless or marine-grade fasteners are recommended for saltwater to reduce corrosion. Rinse all hardware with fresh water after each trip.

Will a mount affect sonar readings?

It can. Vibration, air bubbles and transducer angle all affect readings. Keep the transducer fully submerged, free of cavitation from the prop, and mounted rigidly.

How often should I check the mount?

Check fastener tightness after the first few outings and then periodically, especially after rough water or trailer hauls.

Should I consult a professional for installation?

If you are drilling into a hull, modifying wiring or working on a motor you are unsure about, consult a marine professional or the manufacturer before proceeding.

Conclusion

For most boat owners with a track system, the WINDFRD Fish Finder Track Mount offers the most flexibility. Minn Kota owners will find the MKR-15 kit the most straightforward match. Lowrance 3-in-1 users have two sensible options: the JERBOR plate for a dedicated plate, or the budget-focused Lowrance-to-Minn Kota mount for a durable, simple bridge. Confirm your transducer and motor brand first, and the right trolling motor fish finder mount will follow.
