Overview

The Garmin 010-11681-00 is a flush mount kit for installing an echo 100, echo 150, or echo 300c directly into a flat helm or dash panel. It replaces the look of a bracket-mounted display with a cleaner, built-in fit that sits closer to the console.

The flush-mount template for this installation references 3/8 in. (9.5 mm) and 11/64 in. (4.5 mm) drill sizes during panel prep, so it is worth confirming you have the right bits on hand before you start cutting. The included gasket helps the bezel sit evenly against the panel for a finished look.

This is a good match for tighter helms where a bracket sticks out into the cockpit, or anywhere you want the fishfinder to stay tucked in and less exposed to bumps while docking or fishing.

Key features

• Fits Garmin echo 100, echo 150, and echo 300c units for a true flush installation
• Mounts the display close to the dash to reduce protrusion around the helm
• Includes a flush mount gasket for a cleaner bezel-to-panel transition
• Template references 3/8 in. (9.5 mm) and 11/64 in. (4.5 mm) drill sizes for panel work
• Hardware and instructions are included for the flush-mount install

Compatibility and fit

This kit is specific to the echo models listed and is not a universal mount. Confirm the exact model of your unit before ordering, especially if your display is part of a bundle or has a similar-looking housing.

Flush mounting requires space behind the panel for the power and transducer connections, plus room for the cables to bend without being pinched. If your console has a shallow electronics pocket, check depth and cable routing before cutting the opening.

Installation and setup

A flush install typically involves cutting the dash opening and drilling the mounting holes, then securing the unit from the front using the supplied hardware. Dry-fit everything first, and protect nearby wiring and hoses before you start drilling.

If your dash is wood-cored or composite, seal the exposed cut edges after trimming to keep moisture out over time. Tighten fasteners evenly so the gasket seats properly without stressing the panel.
