Best Fish Finder for Trolling Motor Setups

The best fish finder for trolling motor rigs starts with the YakAttack FFP-1007 mounting plate, a 6 x 3.5 in marine-grade platform that anchors your display and controls to a track system for 1 lb of hardware. If you run a Minn Kota and want the transducer clamped to the lower unit instead, the folosem MKR-15 kit is the better buy. Here's the thing the search hides: no single listing here is a finished fish finder. Each is a part. Know which part you're missing before you buy.

Best fish finder for trolling motor at a glance

What this list actually covers

Search results for the best fish finder for trolling motor pull in the whole ecosystem, not just screens. That's what happened here. The seven products below are mounts, transducers, a graph bracket, and one full trolling motor. Amazon's search read "trolling motor" loosely, so treat that qualifier as a filter you apply yourself.

None of these is a plug-and-play fish finder unit with a display and its own sonar. So don't expect a screen to arrive in the box. What you get is the piece that lets a fish finder work with, or attach to, a trolling motor.

Here's how the parts break down:

• Transducers send and read sonar. Two Lowrance SplitShot and HOOK2 Bullet units are here.
• Transducer mounts clamp that sensor to the motor's lower unit. The folosem, Wosijm and Zonon parts do this.
• Display mounts hold the screen on a track or deck. The YakAttack plate handles this.
• The motor itself is the thing everything clamps to. That's the Newport NV-Series.

Read your own rig before buying. The right part is the one you're currently missing.

How I cut seven listings down to a ranking

I ranked these by disqualification first, then usefulness. Three things pushed picks down the order.

First, missing sonar specs. A transducer mount that lists no compatibility detail is a gamble, so the Wosijm kit sits low despite being the cheapest of the seven. Its listing names Humminbird, Lowrance and Eagle fit, but stops short of the detail the folosem kit gives.

Second, narrow compatibility. The Lowrance HOOK2 Bullet Skimmer fits only HOOK2 4 and HOOK2 4x models. That's a real limit. It drops below the SplitShot, which the listing says fits HOOK2 5, 7, 9 and 12.

Third, whether the part serves the trolling-motor use case at all. The Newport motor is excellent hardware. But it's the motor, not a finder, so it can't win a fish finder ranking even at 55lb thrust.

What survived to the top was the part that helps the most anglers do the most with what they already own. The YakAttack plate mounts almost any display on almost any track. That breadth won it.

1. YakAttack Universal Mounting Plate — Best overall

A 6 x 3.5 in marine-grade platform that bolts your display and controls to a track system without swallowing your deck.

Best for: kayak anglers rigging electronics on track systems Skip it if: your boat has no track mounts

This plate wins the best fish finder for trolling motor list because it solves the problem every other part assumes you've already solved: where does the screen go? At 6 x 3.5 in and 1 lb, it gives you a flat, rigid surface for a display, a throttle control, or both. YakAttack says it locks into their LockNLoad system and holds on GearTrac, MightyMount II, MightyMount XL, and most kayak track mounts.

That track compatibility is the real edge. It means you don't drill your hull. You slide the plate on and lock it down. The listing describes marine-grade corrosion-resistant polymers, which matters if you fish salt. It's model FFP-1007, made in the USA, and carries the brand's Built for Life guarantee per the listing.

The trade-off against the rest of this set: it holds electronics but isn't electronics. You still supply the finder. And its price position sits mid-pack, above the two cheapest mounts.

Pros:

• Compact 6 x 3.5 in surface for tight rigs
• Fits most kayak track systems per listing
• Light 1 lb hardware load
• Marine-grade polymer, salt-ready per listing
• Made-in-USA build with lifetime guarantee claim

Cons:

• Useless without a track mount on your boat
• Holds a display but is not a finder
• Only one seller lists it
• Mid price for a single plate

2. folosem 410150-1 1840201 MKR-15 Transducer Mounting Kit — Most versatile

The Minn Kota transducer clamp that takes almost any brand's sensor without an adapter.

Best for: Minn Kota owners mixing transducer brands Skip it if: you don't run a Minn Kota

If your trolling motor is a Minn Kota, this kit earns its spot. The listing calls it a direct replacement for part numbers 410150-1, 1840201, and MKR-15, mounting a transducer to the lower unit of bow-mount and transom-mount Minn Kota motors. That's the versatile part: folosem says it accommodates transom-mount transducers from Humminbird, Garmin, Lowrance, and Eagle without extra adapters.

The construction claim is aluminum body with stainless steel hardware, aimed at salt and freshwater alike. Installation is described as tool-free, no drilling or permanent changes. That keeps your motor resale-clean. It's the second-cheapest of the seven and carries a 1 year warranty, which the two Lowrance transducers here don't publish.

The gap against the folosem's rivals is data. Beyond colour, warranty and fitment, the listing is thin on measured detail. You're trusting the compatibility claim.

Pros:

• Fits Minn Kota bow and transom motors per listing
• Takes transducers from four major brands
• Tool-free install, no drilling claimed
• Second-cheapest pick with a 1 year warranty

Cons:

• Minn Kota motors only
• Few published specs beyond fitment
• Only one seller lists it
• No transducer included

3. Zonon Fish Finder Mount 18.5'' Graph Mounts for Bass Boats — Best upgrade

An 18.5 in aluminum arm that lifts your graph onto the bow, right behind the trolling motor pedal.

Best for: bass boat owners mounting a graph on the bow Skip it if: deck space is tight

This is the step up from a small plate to a proper graph arm. The bracket is 18.5 in of heavy-duty aluminum alloy, weighs 3.49 lb, and ships with mounting screws. Zonon's pitch is bow placement: the design puts your electronics directly behind the electric propeller pedal, so you glance down and read sonar while you steer.

That positioning is the upgrade for anyone running a bigger display than a kayak plate can hold. The listing describes a low, flat profile meant to reduce tripping hazards on the deck, and a wear-resistant black anodized finish for corrosion resistance. Dimensions run 3.74 x 21.5 x 3.94 in, so measure your bow first.

Against the YakAttack plate, this is heavier and longer. That's the cost of holding a larger graph out where you can see it. It's still an entry-price pick, third-cheapest of the seven.

Pros:

• Long 18.5 in reach for bow placement
• Positions display behind the motor pedal
• Anodized aluminum resists corrosion per listing
• Ships ready to install with screws

Cons:

• Heaviest mount here at 3.49 lb
• Long footprint eats deck space
• Only one seller lists it
• No display or transducer included

4. Lowrance SplitShot Skimmer Transducer — Best for families

Two sonar views from one transducer, so the whole boat sees fish arches and bottom detail.

Best for: HOOK2 5, 7, 9 or 12 owners wanting two sonar views Skip it if: you own a HOOK2 4

This is where actual sonar enters the list. The SplitShot fits Lowrance HOOK2 5, 7, 9 and 12 inch fish finders, and the listing says it delivers DownScan sonar straight down plus CHIRP sonar for fish arches. Two views from one sensor is the family-friendly part: kids reading the screen get the clear picture and the depth detail at once.

Lowrance claims a wider sonar cone with double the coverage of traditional finders. The unit weighs 0.79 lb, measures 3 x 6 x 2 in, and includes a built-in temperature sensor. Setup is flexible. The listing says a single transducer mounts on the transom, inside the hull, on the trolling motor, or through a scupper hole. That trolling-motor option is exactly why it's here.

The catch: it's the most expensive pick of the seven, and it only helps if you own a compatible HOOK2. No display in the box.

Pros:

• CHIRP and DownScan from one sensor
• Fits four HOOK2 display sizes
• Built-in temperature sensor
• Four mounting options including trolling motor

Cons:

• Most expensive pick here
• Needs a compatible HOOK2 display
• No display included
• Only one seller lists it

5. Lowrance HOOK2 Bullet Skimmer Transducer — Best minimal setup

The lightweight single-view transducer for the smallest HOOK2, built for kayaks and tight rigs.

Best for: HOOK2 4 owners on kayaks and small boats Skip it if: you have a larger HOOK2

Keep it simple. This transducer fits Lowrance HOOK2 4 and HOOK2 4x models, and nothing wider. That narrow fit is the whole point: it's the minimal replacement or upgrade for the smallest screen in the range. At 0.8 lb and 3 x 6 x 2 in, it's sized for a kayak deck or a small boat where a graph arm would be overkill.

Lowrance describes a wider sonar cone with double the coverage of traditional finders, plus a built-in temperature sensor. Like the SplitShot, the listing says it mounts on the transom, in the hull, on the trolling motor, or through a scupper hole. For a paired-down rig on a trolling motor, that flexibility is enough.

It ranks below the SplitShot because it's a single-view sensor for one screen size. It also sits in the premium price band despite doing less than the SplitShot. Match it to a HOOK2 4 or skip it.

Pros:

• Light 0.8 lb sensor for kayaks
• Wider cone than traditional finders per listing
• Built-in temperature sensor
• Four mounting positions including trolling motor

Cons:

• HOOK2 4 and 4x only
• Single sonar view, no DownScan
• Premium price for a basic transducer
• Only one seller lists it

6. Wosijm 1840201 Transducer Mounting Kit for Humminbird — Best budget pick

The cheapest way to clamp a transducer to your trolling motor, at just 0.56 lb.

Best for: anyone needing the cheapest MKR-15 replacement Skip it if: you want published sonar specs

If you just need the transducer clamp and price decides it, this is the cheapest of the seven. It's a 1840201 replacement kit, and the listing says it fits Humminbird, Lowrance, Eagle and more. At 0.56 lb, it's the lightest mount here, and it carries a 1 year warranty, matching the folosem kit.

The pitch is safety and durability. Wosijm says mounting the transducer between the sensor and the trolling motor makes driving safer, and describes a marine-grade aluminum body with stainless steel coating to fight rust. Installation is listed as easy, with no drilling mentioned.

Here's why it sits below the folosem despite the lower price: the listing gives you less. It names fewer part numbers, skips the tool-free and stability detail, and stops short of the folosem's fuller compatibility spelling. For a straight budget swap it works. For confidence about fitment, the folosem reads clearer.

Pros:

• Cheapest pick of the seven
• Lightest mount at 0.56 lb
• 1 year warranty
• Aluminum body with stainless coating per listing

Cons:

• Fewer published specs than the folosem
• Compatibility described loosely
• Only one seller lists it
• No transducer included

7. Newport NV-Series 55lb Thrust Saltwater — Best premium

The trolling motor itself, 55lb of thrust on a 30-inch shaft, the thing every mount here clamps to.

Best for: boaters buying the motor the transducer clamps to Skip it if: you already own a trolling motor

This is the one full machine in the group, and it's the priciest pick here. The Newport NV-Series delivers 55lb of thrust from a 12V motor, on a 30" shaft, weighing 23.2 lb. The listing lists a 5-LED battery meter, a 6-inch telescoping tiller handle, and a 3-blade propeller. Speed is 8 settings, 5 forward and 3 reverse, with a trolling top speed described as about 4mph depending on your boat.

Why include a motor in a fish finder guide? Because the rest of this list assumes you own one. If you don't, this is the platform your transducer mount and finder attach to. It needs one 12V deep-cycle battery, 50Ah recommended, not included per the listing. It's the only pick with a 2 year manufacturer warranty and the only one with more than one seller.

It can't win a finder ranking because it isn't a finder. But as the foundation, it's the most complete purchase in the set.

Pros:

• 55lb thrust on a 30" shaft
• 8 speeds, 5 forward and 3 reverse
• 5-LED battery meter and telescoping tiller
• 2 year warranty, longest in the set

Cons:

• Most expensive pick here
• Battery not included
• Not a fish finder at all
• Heaviest item at 23.2 lb

Transducer, mount or motor: which part do you need?

Because none of these is a complete finder, the right buy depends on what your rig is missing. Work through it in order.

1. No trolling motor yet? Start with the Newport NV-Series 55lb. It's the platform everything else bolts to, and it carries the only 2 year warranty here.
2. Have the motor, need a transducer? The Lowrance SplitShot if you run a HOOK2 5 through 12, or the HOOK2 Bullet if you run a HOOK2 4.
3. Have the transducer, need to clamp it to a Minn Kota? The folosem MKR-15 kit, or the Wosijm if price is the only factor.
4. Need to mount the display? The YakAttack plate for a kayak track, or the Zonon 18.5 in arm for a bass boat bow.

Buy the missing link, not the whole chain. A shopper who owns a HOOK2 and a Minn Kota needs only the folosem kit. Someone starting from a bare boat needs the motor first.

Where does a transducer go on a trolling motor?

The best fish finder for trolling motor placement puts the transducer on the motor's lower unit, aimed down into the water. Both Lowrance transducers here list the trolling motor as one of four mounting spots, alongside the transom, inside the hull, and through a scupper hole.

The clamp is what holds it there. That's the job of the folosem and Wosijm kits. They sit between the sensor and the motor. Two things matter when you pick one:

• Motor brand. The folosem is built for Minn Kota lower units. The Wosijm lists broader brand fit.
• Transducer brand. Both kits claim to take Humminbird, Lowrance and Eagle sensors.

A steady clamp keeps the sonar picture clean as you move. The folosem listing specifically claims it eliminates vibration and misalignment at all speeds. Loose mounting is the usual cause of a jumpy screen.

What the listings leave out

Even the fuller listings here stop short of what you'd want to know before you commit. Read around these gaps.

• No transducer ships with any mount. The folosem, Wosijm, Zonon and YakAttack all hold or clamp something you supply separately.
• The mounts don't publish transducer model lists. They name brands, not exact sensor part numbers. Check your transducer against the mount before buying.
• Battery sizing is on you. The Newport motor recommends a 50Ah 12V deep-cycle battery, not included.
• The Lowrance transducers need a matching display. Neither includes a screen, and each fits a specific HOOK2 range.

The pattern across this best fish finder for trolling motor set is clear. These are components. Confirm what your existing gear is, then buy the single piece that completes it. Guessing at compatibility is how a part arrives that won't fit.

The verdict

If you're rigging a kayak or a small boat and need somewhere solid to put the screen, the YakAttack Universal Mounting Plate is the pick. It's 6 x 3.5 in, weighs 1 lb, and locks into most kayak track systems without a drill. That breadth of fit is why it leads.

If you run a Minn Kota and the transducer is what needs securing, the folosem MKR-15 kit is the better call. Its exact advantage is compatibility: it names the 410150-1, 1840201 and MKR-15 part numbers, claims tool-free install, and takes transducers from Humminbird, Garmin, Lowrance and Eagle. It's also the second-cheapest here with a 1 year warranty.

The cutoff is your starting point. Below the waterline, on the motor, you need a transducer and its clamp: the folosem, Wosijm, or a Lowrance sensor. Above deck, holding the display, you need a mount: the YakAttack or the Zonon arm. And if you own no motor at all, the Newport NV-Series 55lb comes first, since everything else attaches to it. Match the part to the gap, and the ranking sorts itself.

FAQ

Is a fish finder for a trolling motor worth it?

A fish finder for a trolling motor is worth it when the transducer sits low and steady on the motor's lower unit. That placement reads the water directly ahead of where you're steering. The clamp kits here, like the folosem MKR-15, exist to hold the sensor firm, which keeps the sonar picture clean while you troll.

What does the best fish finder for trolling motor setup actually include?

The best fish finder for trolling motor setup includes three parts that ship separately here: a transducer for sonar, a mount to clamp it to the motor, and a bracket to hold the display. None of the seven listings bundles all three. You supply the finder head and pair it with the matching mount and transducer for your specific boat.

Will the folosem or Wosijm mount fit any transducer?

Whether the folosem or Wosijm mount fits depends on brand, not any transducer. Both listings name Humminbird, Lowrance and Eagle compatibility. The folosem is designed for Minn Kota lower units specifically, replacing MKR-15 part numbers. Neither publishes an exact sensor model list, so check your transducer against the mount's stated fit before buying to avoid a mismatch.

SplitShot or HOOK2 Bullet: which transducer should I choose?

Choosing between SplitShot or HOOK2 Bullet comes down to your display. The SplitShot fits HOOK2 5, 7, 9 and 12 and gives both CHIRP and DownScan views. The Bullet fits only HOOK2 4 and 4x with a single view, weighing 0.8 lb. Buy the one that matches your screen size, since they aren't cross-compatible.

What mistake do buyers make shopping this category?

The mistake buyers make shopping this category is assuming any listing is a complete finder. It isn't. Search for the best fish finder for trolling motor and you'll get mounts, transducers, and even a full 55lb motor. Each is one component. Confirm what your rig already has, then buy only the missing piece to avoid duplicate parts.

Start by naming the one part your rig lacks, then match it from the list above. If you're building from scratch, the Newport NV-Series 55lb comes first as the platform. If your boat is already rigged and you just need the screen held steady, the YakAttack plate is the sensible default: it's light at 1 lb, fits most kayak track systems, and asks nothing of your existing electronics beyond a place to bolt them. Buy the link, not the whole chain, and every part earns its spot.
