3 GPSMAP 3000 Series Installation Instructions
4. Using the jigsaw, cut the mounting surface along the inside of the solid line indicated on the flush-mount template. Use a file and sandpaper
to refine the size of the hole. Be very careful when cutting this hole. There is only a small amount of clearance between the case and
the mounting holes.
5. Install the four mounting studs into the chartplotter by screwing the shorter, threaded section into the back of the chartplotter. Use the 1 /
16
in.
(2 mm) Allen wrench to tighten the mounting studs until they stop. Do not overtighten - you may damage the mounting stud or the
mounting holes. The studs are coated with a reusable thread-locking patch applied at the factory.
6. Place the chartplotter in the hole and make sure that the mounting studs line up with the pilot holes on the flush-mount template after cutting,
sanding, and filing the hole. If they do not, mark the locations where the studs will feed through the mounting surface.
7. Using the center punch, indent the center of each of the 4 mm mounting-hole locations.
8. Using a
1 /
8
in. (3 mm) drill bit, drill the four mounting holes.
9. Place the chartplotter into the cutout. The four mounting studs should feed through the four mounting holes drilled in Step 8.
10. Place the flat washers over the mounting studs, then thread the hex nuts onto the mounting studs. Tighten all four hex nuts evenly until the
chartplotter is snug against the mounting surface.

Installing the GPS Antenna
To install the GPS 17x antenna, select a suitable location, mount the antenna, and connect the antenna to power and to your GPSMAP 3000
series chartplotter.
Mount the GPS 17x Antenna
You can surface mount the GPS 17x antenna, attach it to a standard 1 in. OD pipe-threaded-pole marine mount (14 threads-per-inch—not
included), or even install the antenna under fiberglass.
Select a suitable location for the GPS 17x antenna on your boat. To ensure the best reception, mount the GPS 17x antenna in a location that has
a clear, unobstructed view of the sky in all directions.
Avoid mounting the GPS 17x antenna where it is shaded by the superstructure of the boat, a radome antenna, or mast.
On a sailboat, avoid mounting the GPS 17x antenna high on the mast, to prevent inaccurate speed readings caused by excessive heeling. •
