RAM MOUNTS Fish Finder Mount for Boats, Marine Electronics Drill-Down Mount with Medium Arm and AMPS Plate, Universal RAM-B-111U

What buyers think

Buyer feedback for the RAM-B-111U is largely consistent around three themes. First, it’s frequently described as stable and secure once tightened down, including use in rougher water. Second, the adjustable RAM ball-and-socket motion is appreciated for finding a comfortable viewing angle and for repositioning where needed. Third, shoppers often point to build feel and overall quality as a reason to choose it over cheaper generic mounts, even when it costs more. Some review comments also suggest setup friction for certain installations, especially around device mounting hardware (for example, missing bolts) and ensuring the device’s hole pattern lines up with the plate.

What this mount is for

This is a drill-down fish finder and marine electronics mount intended for boat installations where you want a fixed base with flexible screen positioning. It uses RAM’s ball-and-socket system, so you can adjust the angle without needing to loosen the entire base every time you want a better view.

Key features and specs that matter

Adjustability for on-water viewing

The core benefit is the ball-and-socket design, which enables near-infinite adjustability. In practical terms, that means you can tilt and aim the screen for different seating positions and lighting conditions.

Marine build for real conditions

The mount is made from power-coated, marine-grade aluminum. It is also described as water resistant, which is important for decks and work areas that see spray and wet conditions.

Device compatibility and mounting patterns

The mount is listed as compatible with multiple Garmin units, including GPSMAP 162, GPSMAP 168, GPSMAP 175, GPSMAP 180, GPSMAP 180C, GPSMAP 182, GPSMAP 185, GPSMAP 188, GPSMAP 232, GPSMAP 238, and Garmin Striker 5 Series, Striker Plus 5cv (and additional Striker Vivid 5cv models). It uses an AMPS mounting plate with selectable hole locations, and the product notes that additional holes may need drilling for proper fit in certain applications.

Weight capacity and mounting form

The mount lists a maximum weight capacity of 6 lb for the device being carried. The unit is compact (item dimensions listed as 6.25 x 2.5 x 5 inches) and uses a medium arm length listed at 3 inches. It’s a drill-down base solution intended for a stable, permanent install.

Pros and cons in real shopping terms

When the RAM-B-111U is a strong fit

• You want easy, repeatable screen aiming for a fish finder or chartplotter, without complicated repositioning.
• You’re building a boat console or deck install where a drill-down base is acceptable and stability is a priority.
• Your device is on the listed compatibility list or uses an AMPS-style mounting pattern that matches the plate layout.
• You’re prioritizing a marine-grade build and durable hardware over the lowest-cost mount.

When you may want a different approach

• Your fish finder requires a very specific hole pattern or mounting hardware that you cannot easily source, since you might need additional fasteners and possibly drilling.
• You’re looking for a plug-and-play mount where the device bolts are always included and perfectly aligned out of the box.

How it compares to “cheaper generic” marine mounts

If you’re comparing options in this category, the decision usually comes down to three things: adjustability feel, stability under vibration, and build quality. Buyers commonly choose the RAM-B-111U when they want a sturdier feel and confidence that the mount stays put after tightening. Budget mounts can work for lighter units or calmer setups, but the tradeoff is often reduced rigidity, less precise aiming, or less confidence during rough-water use. For buyers with more demanding on-water conditions or heavier screens (within the stated capacity), paying for the RAM-B-111U can be the difference between a mount that’s “good enough” and one that you’re comfortable leaving set in your preferred viewing angle.

Setup and installation notes to avoid common fit issues

Because this is a drill-down mount with an AMPS-style plate, take a moment before installing to verify your fish finder’s mounting hole pattern aligns with the plate’s available positions. If your unit’s holes do not line up, you may need additional drilling. Also plan for hardware: some buyers report needing to source bolts for attaching the device to the mount, so check what fasteners your unit uses and whether you already have the correct size on hand.

Verdict

The RAM-B-111U is a solid choice for boat owners who want a stable, adjustable drill-down mount for compatible fish finders and marine electronics. If your device mounting pattern fits the AMPS plate layout (or you’re comfortable doing a bit of installation work), the RAM ball-and-socket adjustability plus marine-grade construction are the main reasons to consider it. If you need strictly plug-and-play hardware and perfect alignment without any additional fasteners or drilling, you may want to double-check device compatibility more carefully or consider a mount designed around your exact unit’s mounting kit.
