Surface-Mounting The Gps 17X Antenna - Garmin GPSMAP 4008 Installation Instructions Manual

To mount the GPS 17 with the cable run outside the mount:
1. Place the cable in the vertical slot along the base of the assembled GPS 17
and pole-mount adapter.
2. Screw the assembled GPS 17 and pole-mount adapter onto a standard 1
in. OD pipe-threaded-pole marine mount (14 threads per inch—not included).
DO NOT overtighten pole-mount adapter. Overtightening the pole-mount
adapter may cut the cable.
3. With the GPS 17 installed on the pole mount, fill the remaining gap in the
cable exit with a marine sealant.
4. Fasten the pole mount to the boat if it is not already attached.
5. Route the cable away from sources of electronic interference, and connect it
to your chartplotter.
To mount the GPS 17 with the cable run through the mount:
1. Position a standard 1 in. OD pipe-threaded-pole marine mount (14 threads
per inch—not included) in the preferred location, and mark the approximate
center of the mount.
2. Drill a hole using a 3 / in. (19 mm) drill bit for the cable to pass through.

4. Slide the cable through the pole mount and screw the assembled GPS 17
and pole-mount adapter onto the pole mount.
5. Route the cable away from sources of electronic interference, and connect it
to your chartplotter.
Mounting a GPS 17x Antenna
The GPS 17x antenna can be surface mounted, installed on a standard 1 in. OD pipe-threaded-pole marine mount (14 threads-per-inch—not
included), or even mounted under fiberglass.

Surface-mounting the GPS 17x Antenna

1 Use the surface-mount bracket as your mounting template.
• Use the center punch to mark the three screw locations on the surface.
• Use a pencil to trace the cable hole in the center of the bracket.
• Set the surface-mount bracket aside. Do not drill through the surface-mount bracket.
2. Select the appropriate drill bit for your mounting surface using the drill bit table (page 4), and drill the three pilot holes.
NotE: If you are mounting the GPS 17x on fiberglass, it is recommended to use a countersink bit to drill a clearance counterbore through the top
gelcoat layer (but no deeper). This will help to avoid cracking in the gelcoat layer when the screws are tightened.
3. Use a 1 in. (25 mm) hole saw to cut the cable hole in the center.
4. Place the seal pad on the bottom of the surface-mount bracket. Make sure
that the screw holes align.
5. Use the included M4 screws to attach the surface-mount bracket to the
mounting surface.
6. Route the NMEA 2000 cable through the 1 in. (25 mm) cable hole and
connect it to the GPS 17x.
7. Make sure the large gasket is in place on the bottom of the GPS 17x
antenna, place the antenna on the surface-mount bracket
clockwise to lock it in place
8. Secure the antenna to the mounting bracket with the included M3 set
screw ➌ .
9. Route the NMEA 2000 cable away from sources of electronic interference,
and connect it to your NMEA 2000 network.
