2. Screw on the receiver base to the stem first, making
sure that the stem pipe does not protude from the
receiver base. This adds protection to the cable
when pulling it through the pipe stem. In addition to
this, deburr the pipe edges to reduce cable
abrasion.
3. Use electrical tape to secure the NMEA pigtail to
the cable as shown in the illustration.
NOTE: Leave the NMEA pigtail secured to the cable unless
needed in order to make it easier to remove the GPS receiver.
4. Route the GPS receiver cable through the stem and
continue with the planned cable route.
5. Attach the GPS receiver to its base using the included
#6 - 1/4” screws. Hand tighten only.
