Overview

The Garmin 010-11977-00 is a flush mount kit for installing compatible Garmin 5-inch marine chartplotters and fishfinders into a flat helm panel for a clean, low-profile finish.

It fits echoMAP 50s and GPSMAP 527, 527xs, 547, and 547xs units, and is commonly used on center consoles, sailboat nav stations, and powerboat dashboards where you want the display seated close to the panel instead of sitting on a bracket.

The kit supplies the mounting support needed to cut a precise opening and secure the unit from the back side of the panel, which helps keep the front of the helm tidy and reduces how far the display protrudes into the cockpit.

Compatibility and fit

This is not a universal flush mount kit. Match it to the model name on your device label before cutting the helm. It is intended for echoMAP 50s and GPSMAP 527, 527xs, 547, and 547xs units.

Flush mounting requires space and access behind the panel for the mounting hardware and for routing power, transducer, and network cables. Check that steering components, switch wiring, and structural supports will clear the back of the unit.

Installation and setup

Use the provided template to mark the cutout on the console, then dry-fit the device before final mounting. A careful test fit helps avoid interference with nearby gauges and lets you confirm the viewing angle from the helm.

After cutting, seal any exposed core material on composite panels and keep fasteners snug without over-tightening. That combination holds up better in vibration and helps prevent moisture from working into the helm over time.

Use cases on board

This kit is a good match when you are building a new dash, refreshing an older helm, or moving a compatible Garmin 5-inch display from a bracket mount to a cleaner panel installation. It is also useful on smaller boats where keeping the display tight to the console reduces snag points around the wheel and throttle area.
