Stem Mount With 1"-14 Thread - Humminbird AS GR50 Installation Manual

A. Stem Mount with 1"-14 Thread
Use the following instructions to stem mount the Sensor:
WARNING! If your Sensor includes a compass (AS GPS HS), do NOT mount it
to a stem mount or antenna pole that contains ferrous metals.
NOTE: It is important to review the mounting considerations and test run the
cable route as indicated in Section 1 before proceeding with the installation.
1. If you have a pre-existing stem mount, skip
to step 2.
If you need to mount the antenna pole
(stem), mark the chosen mounting location
and drill a 3/4" (19 mm) hole for the cable
and cable connector.
If you have purchased hardware to stem
mount your Sensor, follow the instructions
included with that hardware to attach the
stem to the boat.
2. Screw the sensor base onto the stem first,
making sure that the stem pipe does not
protrude from the sensor base. (This adds
protection to the cable when it is pulled
through the pipe stem.) Deburr the pipe
edges to reduce cable abrasion.
3. Use electrical tape to secure the NMEA
pigtail to the cable.
NOTE: Unless it is needed, leave the NMEA
pigtail secured to the cable. If you are
connecting the pigtail to a NMEA 0183
device, see Section 3: Connect to the
Control Head for connection information.
