9 Best Fish Finder Mounts for Boats (October 2026)
The best fish finder mounts for boats include the Scotty 0163 Ball-Mount Fish Finder and Universal for larger displays, the WINDFRD Aluminum Swing Arm Fish Finder Mount for a flat dash, and the VAUBORTTI Aluminum Fish Finder Mount for track rails.
On this page (5 sections)
The Scotty 0163 is the best fish finder mount for boat owners who need a plate designed for larger displays. For a flat dash, consider the WINDFRD swing arm; for a boat accessory track, the VAUBORTTI track base is a better match.
Mount choice starts with the surface, then the screen. A dashboard, open deck, rail track, or existing accessory base can each call for a different fish finder holder for boat use.
If you are still deciding on placement, read our guide to where to mount a fish finder on a boat. Boat layout matters too, so compare mounts for a pontoon boat or jon boat if one fits your setup.

The best fish finder mounts for boats
The right fish finder mount for a boat is the one that fits both your display and its mounting surface. These nine options cover ball mounts, flat bases, track systems, and a combined display and transducer setup.
Scotty 0163 Ball-Mount Fish Finder and Universal: Best for larger displays
- 1.5-inch ball mount
- Plate designed for 7–9 in fish finders
- Full range of motion
- 6.5 in tall
The larger ball and fish finder plate make this a fit for anglers mounting a larger display who want adjustable positioning.
Pros
- Plate designed for larger fish finders
- Smooth full range of motion
- Larger ball offers greater clamping force
Cons
- Requires a compatible ball-mount base
- Check the plate pattern against your display
The Scotty 0163 is the top pick for a larger display because its mounting plate is designed for 7–9 in fish finders. Its 1.5-inch ball mount gives a full range of motion, so you can adjust the screen angle after installation.
The mount stands 6.5 in tall and has a base mount dimension of 2.25 x 2.25 in. Check that you have room for the base and that your device’s mounting holes align with its plate.
This is a ball-mount component, so make sure the rest of your mounting system matches before you choose it. It fits anglers who want an adjustable display position and a plate intended for larger fish finders.
WINDFRD Aluminum Swing Arm Fish Finder Mount: Best for a flat dash
- Aluminum construction
- 6 in arm
- Two pivot points
- 360-degree rotation
A flat-surface base and two pivot points suit a boat dash or deck where you want to angle the screen toward your seat.
Pros
- Two pivot points
- 360-degree rotation
- Designed for flat surfaces
Cons
- Needs a suitable flat mounting area
- Confirm the device plate and fastener fit
The WINDFRD swing arm suits a boat with a flat dashboard or deck and space for its base. Its two pivot points rotate 360 degrees, giving you room to angle the screen toward the helm or another viewing position.
The arm is 6 in long and made from aluminum. WINDFRD says it is designed for screens from 5–12 in and includes different pre-drilled hole patterns for marine electronics.
Measure the mounting surface and check the plate pattern against your display. Choose this mount when you want an arm that can reposition a screen over a flat surface.
VAUBORTTI Aluminum Fish Finder Mount: Best for track rails
- Aluminum construction
- 1.5 in ball
- T-bolt track base
- Oversized adjustment knob
Its T-bolt track base and 1.5-inch ball suit a boat with a compatible rail track and a device plate that matches the hole pattern.
Pros
- Track mounting
- Oversized adjustment knob
- Plate has multiple hole patterns
Cons
- Requires a compatible track
- Check device fit before installation
The VAUBORTTI mount is the track-system pick because its base uses a T-bolt for a compatible rail. A 1.5 in ball and an oversized adjustment knob let you reposition the device without moving the track base.
Its aluminum plate has several pre-drilled hole patterns, including an AMPS pattern. VAUBORTTI lists compatibility with a range of Garmin and Lowrance devices, but confirm your exact model and hole spacing before ordering.
This holder suits a boat that already has an accessory track and a screen plate that fits. If you need a flat surface mount instead, compare a drill-down base.
Vadaxx Fish Finder Mount Base: Best for dual-angle adjustment
- Nylon and stainless steel
- Dual 360-degree swivel balls
- Flat plate with multiple holes
- Separate base and bracket
The two swivel joints give you multiple ways to set the screen angle on a boat surface, while the plate provides several mounting holes.
Pros
- Dual swivel joints
- Base and bracket install separately
- Multiple holes in the plate
Cons
- Check the display's hole pattern
- Not described as water resistant
The Vadaxx base is a fit when you want two swivel joints to aim the display. It uses a flat plate with multiple mounting holes and a nylon and stainless-steel construction.
The upper mount and bracket each rotate 360 degrees. The base and bracket can be installed separately, which may make it easier to fasten the base first and attach the display bracket after.
The device fit still depends on its hole pattern. This fish finder boat holder works for a surface-mount setup where adjustable positioning matters more than a track base.
EDSRDPLT Fish Finder Mount Base: Best for a lightweight composite base
- Marine-grade composite
- Dual ball joints
- AMPS pattern
- Recommended for displays 9 in or smaller
A composite base with dual ball joints offers adjustable positioning for smaller displays, with an AMPS pattern for compatible devices.
Pros
- Dual ball joints
- Quick removal design
- AMPS hole pattern
Cons
- Not compatible with several Humminbird Helix and Solix models
- Not suitable for displays larger than 12 in
The EDSRDPLT mount pairs a marine-grade composite bracket with dual ball joints for adjustable viewing. Its AMPS pattern is intended to fit many fish finders and marine electronics, but model compatibility has exclusions.
EDSRDPLT recommends prioritizing displays 9 in or smaller. It says displays larger than 12 in are not suitable, and it specifically excludes several Humminbird Helix and Solix models.
Check the exact display model before choosing this base. Its quick-removal design can suit boat owners who want to take the mount off when it is not in use.
WINDFRD Fish Finder Track Mount with Transducer: Best for screen and transducer together
- Display and transducer mounting
- 1.5 in double-socket ball
- Track base with T-bolt
- Transducer arm extends 11.42–17.91 in
This combination mount gives the display and transducer separate positions on one setup, useful when your boat has a compatible track or room for its drill-down track.
Pros
- Mounts display and transducer
- Transducer arm extends
- Track can slide for repositioning
Cons
- More parts to position than a display-only mount
- Check track and transducer placement on your boat
The WINDFRD track mount is the pick for anglers who want to position the display and transducer in one system. It includes a display plate, a track base, and a separate transducer arm that extends from 11.42 to 17.91 in.
The base can slide along a compatible track, or its included track can be secured with a drill-down installation. The transducer adapter has a ratcheting slip disc for angle adjustment.
This setup has more parts to place than a display-only mount, so plan the screen, transducer, and cable routes together. Check that the track location keeps the transducer clear and the screen easy to see.
RAM MOUNTS Fish Finder and GPS Mount: Best for marine-grade aluminum
- Powder-coated marine-grade aluminum
- Ball-and-socket adjustment
- 4.66 in arm
- 7.35 in overall height
A drill-down base and ball-and-socket arm suit a flat boat surface where you want a durable metal mount with broad angle adjustment.
Pros
- Marine-grade aluminum
- Near-infinite adjustability
- Lifetime warranty
Cons
- Hardware is not included
- Some devices may need additional holes
The RAM MOUNTS drill-down mount suits a flat boat surface and a buyer who wants a ball-and-socket arm. It stands 7.35 in overall and uses powder-coated, marine-grade aluminum.
The 4.66 in arm allows near-infinite adjustment, while the included plate has AMPS and 3-hole patterns. RAM notes that some devices may need extra holes, and mounting hardware is not included.
Compare the plate with your fish finder before drilling. This is a strong fit when adjustability and an aluminum mount matter more than a track base.
xik 1.5" Ball Medium Arm Fish Finder: Best for a C-size ball system
- 1.5 in ball system
- 5.91 in dual-socket arm
- Aluminum alloy
- Round base and rectangular plate
The C-size ball system offers 360-degree adjustment for compatible devices, with an aluminum base intended for a flat boat surface.
Pros
- 360-degree rotation
- Pre-drilled rectangular plate
- Includes mounting screw kit
Cons
- Not compatible with select Humminbird Helix, Solix and PiranhaMax models
- Check device fit and hole pattern
The xik mount uses a 1.5 in C-size ball system with a 5.91 in dual-socket arm. It includes a 2.4 in round base and a rectangular plate with pre-drilled holes for compatible marine electronics.
The maker lists support up to 16 lb when stationary and 6 lb in motion. It also names several Humminbird Helix and Solix models, plus PiranhaMax, as incompatible.
Check that your display model is supported and that the plate fits. The ball system is useful if you want 360-degree rotation from a surface-mounted base.
LOKTENWO Aluminum Fish Finder Mount for Boat: Best for a medium dual-socket arm
- 1.5 in ball
- 5.7 in dual-socket arm
- Aluminum alloy
- AMPS pattern on round base
The medium arm and round base give you an adjustable option for a flat surface, provided the device and mounting holes fit.
Pros
- 360-degree rotational adjustment
- Pre-drilled plate
- Aluminum alloy construction
Cons
- Not compatible with several Humminbird Helix and Solix models
- Confirm screen and hole-pattern fit
The LOKTENWO mount gives you a 5.7 in dual-socket arm with a 1.5 in ball and a 2.4 in round base. Its rectangular plate measures 6.25 x 2 in and has multiple hole patterns.
The maker says the aluminum-alloy parts have a hard-anodized finish. Its compatibility notes exclude several Humminbird Helix models and Solix 10, so check your specific display before choosing it.
This is an option for a flat surface where a medium arm and ball-joint adjustment fit your layout. The AMPS pattern on the base may help with compatible installations.
How do you choose a fish finder mount for a boat?
Choose a fish finder mount by matching the base to the boat surface and the plate to the display. If you need to mount two displays, see our guide to dual fish finder mounts.
Then check screen reach, adjustability, and any clearance needed for steering or movement.
Start by identifying where the screen can be seen without blocking controls. Our guide to fish finder placement on a boat covers the practical location choices.
Does a fish finder mount fit your boat surface?
A track mount needs a compatible accessory rail, while a drill-down or surface base needs a suitable flat area. Check the base dimensions and the fastener requirements before drilling into a dash or deck.
For a pontoon layout, see our guide to the best fish finder mount for a pontoon boat. For a smaller open boat, our fish finder mounts for aluminum boats guide covers options for that hull style.
Will the plate fit your fish finder?
Check the device model, screen size guidance, and hole pattern before buying. Some plates use universal patterns, but some models need extra holes or are explicitly excluded.
If you also need to secure a removable gimbal display, see fish finder locks.
For installation planning, read how to install a fish finder on a boat. A flush dashboard position may call for a fish finder dash mount instead of an arm that rises above the surface.
Do you need a movable arm or a fixed position?
A ball joint or swing arm helps you angle the screen toward your seat and adjust it for glare. A fixed base can work when the display position is already clear and accessible.
If the screen will sit near the bow, compare fish finder bow mounts. For a broader look at how the display supports fishing decisions, read what fish finders can do.
Should the transducer use the same mount?
A display and a transducer need different positions, so a combined system can help organize both, but it still needs to suit the boat and sonar setup. The WINDFRD track system in this guide includes a separate transducer arm.
If you use a castable unit instead, learn how a castable fish finder works. For an inflatable hull, see the inflatable boat mount guide.
How do you install and route a boat fish finder mount?
Install the base on a surface that leaves the screen visible and reachable, then secure the device plate and route its cables with room for steering and movement. Follow the mount and fish finder instructions for fastener choice and wiring.
Before mounting, compare how to install a Garmin fish finder if that is your device brand. For electrical planning, our guide to wiring a fish finder explains the power connection considerations.
If you use a Scotty system near your rods, the guide to using a Scotty rod holder can help you understand how that separate accessory works. Keep the display mount location clear of rod movement and other controls.

Which fish finder mount should you choose?
Choose the Scotty 0163 if you want an adjustable ball mount with a plate designed for a 7–9 in display. Choose the WINDFRD swing arm for a flat dash, VAUBORTTI for a compatible track, or the WINDFRD combination system when you want a display and transducer arm together.
The best fish finder mount for boat use depends on the surface, device plate, and screen position you can actually use. Measure first, confirm model compatibility, and pick the mount style that fits your layout.

Frequently asked questions
What type of fish finder mount works best on a boat?
The best mount depends on the boat surface and display. A flat dash can take a drill-down or swing-arm mount, while a compatible accessory track can take a T-bolt base.
Check the screen plate pattern, available space, and whether you need to move the display out of the way.
Can I use a fish finder mount on any boat?
Many mounts can attach to a flat boat surface, but the fit depends on the mount base, device plate, and available space. Track mounts also need a compatible track.
Measure the mounting area and compare the hole pattern with your display before drilling or buying.
Should I choose a ball mount or a fixed base?
A ball mount gives you angle adjustment and can help aim the screen toward your seat. A fixed base keeps the setup simpler when the display can stay in one position.
Consider screen access, glare, and whether the mount could interfere with steering or other controls.
Can one mount hold both a fish finder and its transducer?
Some systems include a display plate and a separate transducer arm, such as the WINDFRD track mount in this guide. The transducer still needs a position suited to your boat and sonar setup.
Plan cable routing and clearance before installing either part.
