Mounting the Heading Sensor

If you plan to use your own mounting hardware instead of the included screws, you should test the hardware for magnetic interference before you begin mounting the heading sensor.

You can mount the heading sensor with the power cable routed along the mounting surface or with the cable routed through the mounting surface beneath the sensor.

  1. Select a mounting location (Heading Sensor Mounting Considerations).
  2. If you plan to route the cable through the mounting surface, use an appropriately sized drill bit to drill the cable passthrough hole into the mounting surface at the selected mounting location.
    Make sure to account for the fuse holder when choosing the size of hole to drill.
  3. If necessary, route the cable through the cable passthrough hole.
  4. Use the heading sensor as a template to mark out two pilot holes.
  5. Using a bit appropriate for the mounting surface and mounting hardware, remove the heading sensor and drill two pilot holes.
  6. Secure the sensor to the mounting surface, observing these guidelines for best performance:
    • Ensure you do not overtighten the mounting screws. You should tighten the screws enough to keep the sensor in place, but not so tight that they may strain the device housing.

    • Apply the same amount of force to each mounting screw as you install them.

    • You should install the mounting screws perpendicular to the mounting surface (not at an angle). The heads of the screws should rest in the center of the grooves.

  7. If you routed the cable through the mounting surface, fill the cable hole in the side of the sensor with marine sealant (optional).
