THE QUICK TAKE
Is it right for you?
Choose it for a supported Humminbird bracket that needs the D-size assembly. The short arm gives angle adjustment above a broad screw-down base.
Do not treat it as a universal mount for every large screen. Match the exact display and bracket to RAM’s current fit list. Larger configurations may require the separate Hi-Torq wrench package.
01 / BUYING NOTES
Before you buy.
Match the plate and hole pattern.
The manufacturer lists specific Humminbird models. Check the bracket pattern against the plate; the outside plate size is different from the spacing between its holes.
The base needs solid support.
The broad lower flange spreads the attachment points, but the deck still needs suitable fastening and backing. Plan access below the mounting position.
Check the view from behind.
Leave the power and transducer leads enough room at the rear of the display. Moving the arm should not pull connectors or trap cables.
02 / AMAZON REVIEWS
The buyers’ view.
Owners describe a sturdy mount that holds position and is easy to loosen, reposition and tighten. One found it much heavier than expected but useful for positioning a display above a crowded dash.
Installation takes some preparation: buyers report supplying their own mounting hardware, and one also received no boat-installation instructions. That owner found attaching the display straightforward but was still working out the console mounting.

RAM distinguishes the outer plate dimensions from its rectangular mounting-hole pattern and lists exact Humminbird families. Its compatibility note recommends a Hi-Torq wrench for larger configurations.
The selected RAM-D-202-25-C-202U is the D-size mount without the separate Hi-Torq wrench. It is not the similarly named wrench-included bundle.
