Step 1: Select a Location for the GMI 10
Consider the following when you select an installation location:
•
Provides optimal viewing as you operate your vessel.
•
Allows easy access to the keypad on the GMI 10.
•
Is strong enough to support the weight of the GMI 10 and protect it from excessive vibration or shock.
•
Allows room for the routing and connection of the cables for power and data. There should be at least a
3-inch (8 cm) clearance behind the case.
•
Is at least 9
/
in. (241 mm) from a magnetic compass, to avoid interference.

Mount the GMI 10 in an area that is not exposed to extreme temperature conditions.
NOTE: The temperature range for the GMI 10 is from 5°F to 158°F (from -15°C to 70°C). Extended exposure to
temperatures outside this range (in storage or operating conditions) may cause failure of the LCD screen or other components.
This type of failure and related consequences are not covered by the manufacturer's limited warranty.
Step 2: Flush Mounting the GMI 10
In addition to four of the included mounting screws (number 8 ANSI (4.2 × 1.4 DIN7981)), flush mounting the GMI 10
requires the following tools:
•
Phillips-head screwdriver
•
Drill and drill bit (refer to the Pilot Hole Size Table on
•

•
Jigsaw
•
Scissors
•
Center punch and hammer
•
File and sandpaper
•
Anti-seize lubricant (optional)
•
Counterbore bit (for fiberglass installations)
NOTE: Ensure that the surface on which you mount the GMI 10 has sufficient open space behind it to accommodate the GMI
10 and the connected wires.
To flush mount the GMI 10:
1. The flush-mount template is included in the product box. Trim the template and ensure it will fit in the location at
which you want to flush mount the GMI 10.
2. The flush-mount template has adhesive on the back. Remove the protective liner and apply the template to the
location where you want to flush mount the GMI 10.
3. If you will be cutting the hole with a jigsaw, and not a 3
saw, use a
/
in. (10 mm) drill bit to drill a pilot hole as indicated on the

template to begin cutting the mounting surface.
4. Using the jigsaw or 3
along the inside of the dashed line indicated on the flush-mount template.
Use a file and sandpaper to refine the size of the hole.
5. Place the GMI 10 into the cutout, to confirm that the four mounting-holes are
correct after refining the hole. If not, mark the correct locations of the four
mounting holes. Remove the GMI 10 from the cutout.
6. Using the center punch, indent the center of each of the four mounting-hole
locations.
