Best Fish Finder Mounts: 6 Picks for Boats, Kayaks, and Consoles

The right fish finder mount depends on where the display will live and how big it is: a console or gunwale on a boat, a track on a kayak, or a dash where a gimbal bracket sits. For most boat owners whose Garmin or Lowrance unit is on RAM’s compatibility list, our pick is the RAM Drill-Down Marine Electronic Mount (RAM-111U), an aluminum ball-and-socket mount whose maker lists dozens of compatible units. Kayak anglers on a track system should look at the YakAttack options, and Scotty users already have a post system the Scotty mounts drop into.

These are mounts for the display head unit, not for the transducer that goes in the water. We compared six on mounting style, which units they fit, material, what is in the box, and any stated load or screen-size limit.

Our Top Picks at a Glance

• Best Overall: RAM Drill-Down Marine Electronic Mount. An adjustable aluminum arm on a drill-down base, with a compatibility list on RAM’s site that covers Garmin, Lowrance, Power-Pole, and SI-TEX units.
• Runner-Up: Scotty 368 Universal Sounder Mount. The only other mount here from an approved brand with a large base of owner ratings and a high average; it takes your unit’s own bracket on a Scotty post.
• For 7 to 9 in Screens: Scotty 367 Universal Fish Finder Mount. The only mount here whose maker states a screen-size range.
• For Lowrance Hook2 4 and 5 on Kayak Track: YakAttack Lowrance Hook2 Fish Finder Mount. Replaces the factory base on four named Lowrance and Simrad models.
• For Custom Kayak Track Setups: YakAttack Universal Mounting Plate. A blank 6 x 3.5 in plate you drill to fit, per YakAttack.
• For Humminbird Helix 12: Humminbird GM H12 Gimbal Mount. A gimbal bracket the listing names for all Helix 12 models.

Fish Finder Mounts Compared

RAM, Scotty, and YakAttack details come from their product pages, which we read for each model; the Humminbird row comes from its Amazon listing and Humminbird’s accessory guide. Scroll sideways on a phone to see every column.

How We Chose

We looked at head-unit mounts sold new on Amazon in the United States by RAM, Scotty, YakAttack, and Humminbird, with no other company listed as the manufacturer. Transducer arms, camera mounts, and generic track bases that turned up in the same searches were left out because they do not hold a display. We read each full Amazon listing, then each maker’s product page: RAM’s, Scotty’s, and YakAttack’s pages loaded, and where a listing and a maker page disagree we go by the maker. For the GM H12 we used its listing and Humminbird’s accessory guide, which lists it as a replacement bracket kit for the HELIX 12 Series.

Our Best Overall needs an approved brand, a large base of owner ratings, and a high average. The runner-up, the Scotty 368, is the only other mount here that clears that same bar; it trails the RAM on average rating. After those two, the list is grouped by mounting style rather than ranked: the second Scotty post mount, the two YakAttack track mounts, then the Helix 12 gimbal. Go by the labels, not the position. Two of the six listings had owner reviews we could read (the RAM and the YakAttack plate). We do not run our own product trials. Owner ratings form the base of each AnglerTechLab Score, with a limited editorial adjustment described on our How We Review page. More rigging gear is in our Mounts and Transducers section, and the units themselves are in Fish Finders.

Fish Finder Mount Reviews

1. RAM Drill-Down Marine Electronic Mount (Best Overall)

Who it’s for: Boat owners whose unit is on RAM’s compatibility list and who want it off the dash and on a console side, a gunwale, or a deck, with an angle they can change underway.

Standout features: RAM’s product page describes a powder-coated, marine-grade aluminum kit: a 2.5 in round base you bolt down, a medium double-socket arm, and a 6.25 x 2 in rectangular plate with several pre-drilled hole patterns for a fish finder or a gimbal bracket. The 1.5 in ball joints let you tilt and swing the display, and the mount stands 7.35 in tall. RAM’s compatibility list names Garmin ECHOMAP, GPSMAP, and Striker units, Lowrance Eagle, Elite, HDS, Hook Reveal, and HOOK2 models, the Power-Pole Vision 7, and several SI-TEX units; it names no Humminbird or Raymarine models. The Amazon listing says the mount fits Humminbird and Raymarine fish finders without naming any model, so for those brands check the hole pattern or ask RAM before buying. RAM notes that some units need extra holes drilled in the plate, and according to RAM the mount carries a lifetime warranty.

RAM rates the mount at 4 lb for standard use and 3 lb for heavy-duty use. The Amazon listing gives a 2 lb maximum, which RAM’s page does not support, and that mismatch carries a small deduction in its AnglerTechLab Score. Go by RAM’s page: if the boat pounds through chop, keep the unit and its bracket within the 3 lb heavy-duty figure.

• Pro: The longest model-by-model compatibility list in this guide.
• Pro: Arm and display detach from the base, which stays on the boat, as one kayak owner describes.
• Con: No bolts or nuts for the base, per the listing and one owner.
• Con: Load figures differ between RAM’s page and the listing.

What owners say: Six of the eight reviews we could read describe boat electronics, and the common thread is a solid hold. Owners report it holding a Garmin 7 in unit on a gunwale, a Lowrance FS9 at the helm in rough water, a Simrad Cruise 7, a Garmin 7 in chartplotter on top of a helm, and a GPS and depth finder on the side of a console. One kayak angler likes how quickly the arm and display detach from the base at the ramp. The complaints are small: one owner expected bolts in the bag, one wants a cover for the base screws, and the kayak owner wishes the base had a pass-through for the power cable. Of the other two, one uses it for a satellite dish on an RV and one simply calls installation easy.

Skip it if: you fish from a kayak with a track system and want nothing drilled, you run a Humminbird or Raymarine unit, which RAM’s page does not name, or your unit is not on RAM’s list at all. For any unit, check its weight against RAM’s 3 lb heavy-duty figure.

2. Scotty 368 Universal Sounder Mount (Runner-Up)

Who it’s for: Boat and kayak owners who already use Scotty rod holders or bases and want the fish finder to drop into the same post system.

Standout features: On Scotty’s product page, the 368 pairs a multi-pattern universal top plate with Scotty’s post mount design for quick removal and adjustable rotation. You fasten your fish finder’s own bracket to the top plate, then lock the post into a Scotty mount. Scotty states that the fish finder, the 241L Locking Side Deck Mount, and the fasteners are not included, so plan on buying a base. The Amazon listing gives the material as aluminum; Scotty’s page does not say.

• Pro: Takes your unit’s own bracket on a multi-pattern plate; Scotty does not list compatible brands, so match the hole pattern first.
• Pro: Quick removal from its base, per Scotty.
• Con: Needs a Scotty base and fasteners, sold separately.
• Con: No screen-size or load limit stated by Scotty.

Skip it if: you have no Scotty bases on the boat and do not want to add one, or you want a mount whose maker states a screen-size range, which Scotty gives only for the 367 (7 to 9 in).

3. Scotty 367 Universal Fish Finder Mount (For 7 to 9 in Screens)

Who it’s for: Scotty users with a mid-size 7 to 9 in unit who want full rotation on a post mount.

Standout features: Scotty’s product page calls the 367 the mount for 7 to 9 in screens, with a multi-pattern top plate for most popular brands, a post that fits any Scotty post mount bracket, and a full 360 degrees of rotation. It is engineering-grade nylon with stainless steel fasteners, needs some assembly, and its accessories are sold separately. The Amazon listing also lists “Cotton” among its features, which conflicts with the nylon on Scotty’s page and the listing’s own feature line; that listing error carries a small deduction in its AnglerTechLab Score.

• Pro: The only mount here with a maker-stated screen-size range.
• Pro: Full 360-degree rotation, per Scotty.
• Con: Needs a Scotty base, sold separately.
• Con: Nylon, where the RAM is aluminum.

Skip it if: your unit is under 7 in or over 9 in, or you would rather have an aluminum arm bolted to the console.

4. YakAttack Lowrance Hook2 Fish Finder Mount (For Lowrance Hook2 4 and 5 on Kayak Track)

Who it’s for: Kayak anglers running a small Lowrance Hook2 or Simrad Cruise who want the display on the track.

Standout features: YakAttack’s product page says the FFP-1006 replaces the factory base on the Lowrance Hook2 4 and 5, Reveal 5, and Simrad Cruise 5, and allows one-handed adjustment of the display. It attaches with the LockNLoad system to YakAttack MightyMount and GearTrac and most track systems from Scotty, RAM, and YakGear. FeelFree, 3 Water Kayaks, and Jonny Boats need YakAttack’s AAP-1012 adapter, and the track itself is not included. YakAttack says it is made in the USA and covered by its Built for Life Guarantee.

• Pro: Purpose-built for four named units, so no drilling or plate fitting.
• Pro: Fits most kayak tracks, per YakAttack.
• Con: Fits only those four models.
• Con: Some kayak brands need a separate adapter.

Skip it if: your unit is anything other than those four models, or your kayak has no track. The Amazon listing’s description also mentions other YakAttack mounts for larger Lowrance, Garmin, Humminbird Helix, and round-base units; those are separate products.

5. YakAttack Universal Mounting Plate (For Custom Kayak Track Setups)

Who it’s for: Kayak anglers whose unit has no model-specific track mount, or who want one plate for a fish finder, a trolling motor controller, or other gear.

Standout features: YakAttack’s product page describes a 6 x 3.5 in flat top plate with no holes on a LockNLoad base, with the same track compatibility and adapter note as the Hook2 mount. It is a do-it-yourself part: YakAttack says you drill holes to mount a unit such as a Humminbird PiranhaMAX 4, and no screws, nuts, or washers are included because every install differs. The Amazon listing gives the material as plastic and describes corrosion-resistant polymers.

• Pro: Designed for attaching just about anything, per YakAttack, including fish finders and trolling motor throttles.
• Pro: Owners also use it for trolling motor controls.
• Con: You drill the plate and supply your own hardware.

What owners say: Two of the eight reviews describe mounting a fish finder, one a Lowrance 7, and that owner calls it sturdy and able to take almost any display. Three owners use it for other gear: two for trolling motor controls and one for a YakAttack Track Pack; one of them calls it sturdy and easy to install and remove. Two short reviews call it strong or as advertised.

Skip it if: you own one of the four units the FFP-1006 is made for, or you do not want to drill and source hardware.

6. Humminbird GM H12 Gimbal Mount (For Humminbird Helix 12)

Who it’s for: Helix 12 owners who want a second mounting spot on the boat or need to replace a gimbal bracket.

Standout features: According to the Amazon listing, the GM H12 is compatible with all Helix 12 models, comes with knobs and mounting hardware, and carries a one-year limited warranty; its specification table lists aluminum. Humminbird’s accessory guide lists the GM H12 (740151-1) as a replacement mounting bracket kit with attachment screws and knobs, compatible with the HELIX 12 Series; neither source gives a weight.

• Pro: Made for the Helix 12, so no adapter plate.
• Pro: Mounting hardware included, per the listing.
• Con: Fits only the Helix 12.
• Con: Few details: no weight or dimensions from the listing or Humminbird.

Skip it if: you own any other Humminbird size, or you want the display on an arm that swings out over the gunwale.

How to Choose a Fish Finder Mount

If you are still choosing the fish finder itself, settle that first: the unit’s size, weight, and bracket decide which mount works.

Start With Where the Display Goes

On a bass boat or center console, a dash or console spot usually takes either the unit’s own gimbal or a drill-down arm like the RAM, which can sit on the side of the console to keep the view ahead clear. On a jon boat or a skiff without a console, a gunwale or seat-side spot works with an arm or a Scotty post. On a kayak, a track mount keeps holes out of the hull and lets you slide the display within reach; YakAttack’s mounts are built for that, and Scotty’s posts work with Scotty bases.

Match the Screen Size and Weight

Only two makers here state limits: Scotty sizes the 367 for 7 to 9 in screens, and RAM rates its mount at 4 lb standard and 3 lb heavy-duty (the Amazon listing’s 2 lb figure does not appear on RAM’s page). If you are shopping for heavy duty fish finder mounts, find your unit’s weight in its manual, add the bracket, and leave margin for a boat that pounds through chop. For a Helix 12, the GM H12 is the model-specific option here.

Check How the Unit Attaches

Mounts here take the unit in four ways. Model-specific mounts (the YakAttack FFP-1006, the Humminbird GM H12) are made for named units, so they skip the adapter plate. Multi-pattern plates (both Scotty mounts) take the fish finder mounting bracket that came with your unit. The RAM plate has pre-drilled patterns but may need extra holes, and the YakAttack plate is blank, so you drill it. Hold your unit’s bracket against the maker’s hole pattern before ordering.

Plan the Cables and Removal

The power and transducer cables have to reach the display at every angle you plan to use, so leave slack at the arm or swivel. If you clear the deck at the ramp, a mount whose arm, post, or track base comes off (RAM, Scotty, YakAttack) removes more than the unit itself. Follow your fish finder’s installation manual for wiring and fusing; this guide does not cover electrical work.

Head Unit Mount or Transducer Mount

A fish finder needs two mounts: one for the display you look at and one for the transducer in the water. Everything in this guide holds the display. The transducer goes on the transom, the trolling motor, a through-hull fitting, or a kayak arm, and each needs its own hardware. For the motor side of the boat, our trolling motor mount roundup covers bow brackets and kayak transom plates.

Frequently Asked Questions

How do you mount a fish finder?

Pick the spot, bolt down the mount or its base, attach the unit, then route the power and transducer cables. Our step-by-step guide to install a fish finder on a boat covers the full process.

What is the best way to mount a fish finder on a kayak?

A track mount is a common answer for a kayak mounted fish finder, since the YakAttack FFP-1006 listing says it attaches to most kayak tracks without drilling. Use the FFP-1006 for the four units it names and the YakAttack plate for others. Our guide to mounting a fish finder on a kayak walks through the steps.

How do you install a YakAttack fish finder mount?

Per YakAttack, the FFP-1006 replaces the factory base on the unit and attaches to the kayak’s track with its LockNLoad system. FeelFree, 3 Water Kayaks, and Jonny Boats need the AAP-1012 adapter first. Follow the instructions that come with the mount.

Can you mount a fish finder to a trolling motor?

The display stays on the deck, console, or track. What attaches to the trolling motor is the transducer, usually with a clamp or bracket on the motor shaft; see our guide on how to mount a transducer to a trolling motor.

Will a RAM mount fit a Garmin, Lowrance, or Humminbird?

RAM’s list for the RAM-111U names many Garmin and Lowrance units but no Humminbird or Raymarine models, although the Amazon listing claims Humminbird and Raymarine compatibility without naming a model. For a unit not on the list, compare its bracket’s hole pattern with the RAM plate, or contact RAM before ordering.
