Overview

The Garmin 010-12239-01 is a flush-mount gasket for the GNX 130 marine instrument, used when you want the display to sit cleanly against a dashboard or instrument panel. It matches the GNX 130 housing footprint of 249 x 153 x 19 mm (9.8 x 6.02 x 0.75 in.).

In a flush installation, the gasket sits between the instrument and the panel cutout. A thin bead of marine sealant around the gasket helps reduce water that can work behind the dashboard during spray or washdowns.

This is a practical match for refits where the GNX 130 is being moved to a new panel, removed for service, or re-bedded to tidy up the sealing surface behind the display.

Key features

• Made specifically for Garmin GNX 130 flush-mount installations, not a universal gasket
• Helps the instrument sit tight against most flat mounting surfaces for a cleaner bezel-to-panel finish
• Supports sealing the panel cutout when a small bead of marine sealant is applied around the gasket
• Works with the standard GNX 130 flush-mount pattern that uses a 44 mm (1 3/4 in.) starter hole and 4.5 mm (3/16 in.) mounting holes
• Handy to keep aboard as a spare for quick re-installs during electronics work

Installation and setup

Plan for a mounting surface that is flat and strong, with enough clearance behind the panel for cable routing and access to the mounting hardware. Use the GNX 130 flush-mount template to lay out the cutout and holes before you start drilling and cutting.

Set the gasket on the back of the instrument before fastening it in place, then bed it with a thin bead of marine sealant around the gasket if you want to limit seepage behind the dashboard. Tighten the fasteners evenly so the gasket compresses without pulling the panel out of flat.

Compatibility and fit

Compatibility is limited to Garmin GNX 130 instruments. The GNX 130 connects through a NMEA 2000 network and is powered from the backbone (9 to 16 Vdc), so choose a mounting location that also allows a clean route for the NMEA 2000 drop cable.

Use on board

Common mounting spots are the helm dash, cockpit pod, nav station, or bulkhead panels where a flush face is easier to wipe down and less likely to catch on lines and gear. It is most useful on boats that see regular washdowns, salt spray, or frequent instrument servicing.
