Under Helm or Bulkhead Mounting
1.
Using the dimensions from Under Helm Bracket and Connector Clearance Dimensions, choose a suitable location to
mount the GPS sensor under helm bracket.
2. Route the NMEA 2000 harness through the under helm bracket.
3. Thread and tighten by hand the NMEA 2000 harness end onto the GPS NMEA receptacle, being careful not to
cross‑thread the fittings.
4. Remove the paper covering on the adhesive ring located on the bottom of the GPS sensor.
5. Install the GPS sensor into the under helm bracket. Press firmly in multiple locations around the GPS sensor to ensure
360‑degree contact between the adhesive ring and the under helm bracket.
6. Place the under helm bracket assembly flush against the underside of the helm or the bulkhead surface.
7. Mark and use a 3.18 mm (1/8 in.) drill bit to pre‑drill the screw holes into the underside of the helm or the bulkhead
surface.
IMPORTANT: Do not overtighten the two screws.
NOTE: Different deck materials may require the screws to be tightened to specific torque values.
8. Install the under helm bracket assembly under the helm or the bulkhead surface with the two screws.
