Quick Verdict: Is the RAM-111U-B Worth Buying?
While you might expect a basic mount to compromise on durability or adjustability, the RAM-111U-B delivers a technically sound solution: its power-coated marine-grade aluminum plate and C-size (1.5″) ball with RAM ball-and-socket technology provide robust corrosion resistance and near-infinite positional adjustment, and the short-arm, drill-down configuration yields a low-profile, stable platform for fishfinders and chartplotters. You’ll get a mount that minimizes mount corrosion risk and maintains clamping torque under load. Vibration isolation is effective for reducing sensor noise on sonar displays. For marine electronics, it’s a precise, reliable choice if you need compact, durable adjustability. We also carry a selection of kayaks and accessories designed for anglers and water adventures.
What’s in the Box and Exact Specs (Plate Size, C 1.5 Ball, Dimensions, Weight)
Having established the RAM-111U-B’s durability and adjustability, let’s look at exactly what you get and the unit’s precise dimensions. You get one drill-down mount assembly: a 6.25″ x 2″ mounting plate, short arm with C-size 1.5″ ball, base plate, hardware kit and installation instructions. Plate dimensions match common fishfinder footprints; ball diameter is 1.5″ (C). Overall height is 5.225“. Mount weight is 1.1 pounds. Material finish is black powder-coated, marine-grade aluminum. Packaging lists model 3002.9502 (RAM-111U-B) and includes a lifetime manufacturer warranty. These mounts are ideal for use with kayaks and other small watercraft due to their corrosion-resistant design and secure attachment points for water adventures.
Who This Mount Fits: Compatibility With Garmin, Lowrance, Humminbird, Raymarine, and Common Use Cases
Because the RAM-111U-B uses a standard C-size (1.5″) ball and a 6.25″ x 2″ plate, it directly accommodates a wide range of Garmin, Lowrance, Humminbird and Raymarine fishfinders and chartplotters that share compatible hole patterns or can be adapted with the included hardware. You’ll get reliable Garmin integration for mid-size ECHOMAP/GPSMAP units and solid Lowrance fitment for HDS Carbon and LIVE 7 series. Humminbird compatibility and Raymarine mounting are supported for many compact displays. Use cases include Boat consoles and Center consoles, compact Kayak setups and mounts near Trolling motors where a low-profile, marine-grade aluminum drill-down solution is required. This mount is ideal for outdoor enthusiasts shopping for kayaks and transducer arms and other marine accessories.
Installation and Adjustability: Drill-Down Setup, Tools, Mounting Tips, and RAM Ball-and-Socket Positioning
Start by marking and pre-drilling the footprint: position the 6.25″ x 2″ plate where you want the display, trace the holes, and drill pilot holes sized for the recommended marine-grade fasteners (typically 1/4″ or #14 screws depending on hull material and backing). Use sealant under the plate, stainless fasteners, and backing plate or nyloc nuts to distribute load. Torque settings should follow RAM specs; avoid over-torquing aluminum components. Assemble the short arm and C (1.5″) ball, tighten the socket knob to set friction, then fine-adjust. Inspect fasteners periodically for looseness and mount corrosion, re-torque as required. Consider pairing your mount with a waterproof duffel to keep electronics and accessories dry during launches and trips.
Real-World Performance, Durability, Warranty, and Final Pros & Cons
While you’ll likely notice the RAM-111U-B’s secure hold and adjustability on day one, its real-world performance becomes evident over months of use in saltwater conditions: the power-coated marine-grade aluminum resists corrosion, the C (1.5″) ball-and-socket maintains tension without creep, and the short arm keeps display vibration and flex to a minimum under typical boating speeds. You’ll see consistent vibration resistance in choppy seas; corrosion testing protocols show minimal surface pitting. The lifetime warranty protects against material failures. Pros: rigid, low-maintenance, compact. Cons: limited articulation compared to longer arms, drill-down installation required for peak stability. For kayakers and boating enthusiasts shopping for accessories, this mount fits well with other marine compass and gear options found at specialty retailers.
Some Questions Answered
Can This Mount Be Used on Non-Marine Vehicles Like ATVS or Trucks?
Yes — you can use it on ATVs and trucks. You’ll get ATV compatibility and Truck installation by mounting the drill-down plate to any flat, rigid surface; the C-size 1.5″ ball and short arm provide robust ball-and-socket adjustability. Its marine-grade aluminum and powder coat resist corrosion and vibration, but you’ll need appropriate fasteners and possibly backing reinforcement for shock loads. Verify electronics footprint matches the 6.25″ x 2″ plate.
Are Replacement Short Arms or Plates Available Separately?
Yes — you can source replacement arms and aftermarket plates separately. You’ll want RAM’s genuine short arm and drill-down plate or compatible aftermarket plates that match the C (1.5″) ball and 6.25″ x 2″ bolt pattern. Verify material, corrosion resistance, and hole spacing to maintain torque spec and load rating. Use OEM part numbers or measured dimensions when ordering to guarantee proper fit, repeatable adjustability, and marine-grade durability.
How Resistant Is the Finish to Salt Spray and UV Over Years?
You’ll find the power-coated, marine-grade aluminum finish resists salt spray and long term UV well; RAM’s corrosion testing shows minimal pitting or coating breakdown under accelerated salt-fog cycles. Expect slow cosmetic fading from prolonged sun exposure, but structural integrity and attachment reliability remain. For best results you should rinse with fresh water after salt exposure and inspect seals periodically; replacement components are available if finish or parts degrade.
Does the Mount Interfere With Chartplotter Heat Dissipation?
No, it typically won’t; the drill-down plate and short arm avoid direct thermal insulation against the chartplotter’s case, so you won’t force heat to build. You should still orient the device to prevent airflow obstruction from the mount or nearby structures. Because the aluminum plate conducts heat and the ball-and-socket keeps clearance, you can expect adequate passive dissipation, but allow recommended clearance per the device manufacturer for peak cooling.
Can the Plate Accommodate Custom Cable Routing or Conduit?
Yes — you can route cables under and around the 6.25″ x 2″ plate for tidy cable management. The plate’s flat, open underside and short-arm spacing let you secure wiring ties or small conduit without obstruction. For conduit compatibility, use flexible marine-grade conduit (1/4″–3/8″) and route clamps to the drill-down base. You’ll want corrosion-resistant ties and sealant at penetration points to maintain watertight integrity.
