Mounting Considerations

NOTICE

This device should be mounted in a location that is not exposed to extreme temperatures or conditions. The temperature range for this device is listed in the product specifications. Extended exposure to temperatures exceeding the specified temperature range, in storage or operating conditions, may cause device failure. Extreme-temperature-induced damage and related consequences are not covered by the warranty.

Using the included hardware and template, you can flush mount the chartplotter in the dashboard.

When selecting a mounting location, observe these considerations.

  • You should mount the chartplotter to provide an optimal viewing angle as you operate your boat.

  • You must select a location that is strong enough to support the weight of the chartplotter and protect it from excessive vibration or shock.

  • You should select a location that allows for easy access to all interfaces, such as the keypad, touchscreen, and card reader, if applicable.

  • To avoid interference with a magnetic compass, you must not mount the chartplotter closer to a compass than the compass-safe distance value listed in the product specifications.

  • You must select a location that allows room for the routing and connection of all cables.

  • If the mounting location is in direct sunlight and in a horizontal orientation, ensure that the installation location meets as many of the following criteria as possible:

    • Sufficient air flow

    • Proper ventilation

    • Cooling source on the front and rear of the chartplotter

    • Method to shade the display using a canopy, window tint, or shroud

    NOTE: If possible, you should meet all of these criteria when installing the chartplotter.

Bail Mounting the Device

NOTICE

If you are mounting the bracket on fiberglass with screws, it is recommended to use a countersink bit to drill a clearance counterbore through only the top gel-coat layer. This will help to avoid cracking in the gel-coat layer when the screws are tightened.

You can use the bracket to bail mount the device on a flat surface.

  1. Using the bail-mount bracket 1 as a template, mark the pilot holes 2.

  2. Using a 3.2 mm (1/8 in.) drill bit, drill the pilot holes.
  3. Secure the bail-mount bracket to the surface using the included washers and wood screws 3.
  4. Install the bail-mount knobs 4 on the sides of the device.
  5. Place the device in the bail-mount bracket, and tighten the bail-mount knobs.
  6. Install the trim caps by snapping them in place around the edges of the device.

Flush Mounting the Device

NOTICE

Be careful when cutting the hole to flush mount the device. There is only a small amount of clearance between the case and the mounting holes, and cutting the hole too large could compromise the stability of the device after it is mounted.

NOTICE

Use only the included hardware when mounting this device. Using mounting hardware not provided with the device may damage the device.

NOTICE

To avoid potential damage to the powder coating, use only the included screws to mount the device. Using screws other than the ones included will void your warranty.

NOTICE

Do not remove the blue, rubber protective bumper until after the installation is complete. The bumper helps protect the device from damage during installation.

NOTICE

If you will not have access to be back of the device and the microSD® memory card slots after installations, you should install the microSD memory card prior to installation.

The included template and hardware can be used to flush mount the device in your dashboard. There are three options for hardware based on the mounting surface material.

  • You can drill pilot holes and use the included wood screws.

  • You can drill holes and use the included nut plates and machine screws. The nut plates can add stability to a thinner surface.

  • You can drill holes, tap them to M4, and use the included machine screws.

  1. Trim the template and make sure it fits in the location where you want to mount the device.
  2. Secure the template to the selected location.
  3. Using an 14.6 mm (9/16 in.) drill bit, drill one or more of the holes inside the corners of the solid line on the template to prepare the mounting surface for cutting.
  4. Using a jigsaw or rotary tool, cut the mounting surface along the inside of the solid line on the template.
  5. Place the device in the cutout to test the fit.
  6. If necessary, use a file and sandpaper to refine the size of the cutout.
  7. After the device fits correctly in the cutout, ensure the mounting holes on the device line up with the larger 6 mm (1/4 in.) holes on the template.
  8. If the mounting holes on the device do not line up, mark the new hole locations.
  9. Based on your mounting surface, drill or punch and tap the larger holes:

    • Drill 3.2 mm (1/8 in.) pilot holes for the included wood screws, and skip to step 18.

    • Drill 6 mm (1/4 in.) holes for the included nut plate and machine screws.

    • Drill and tap M4 holes for the included machine screws, and skip to step 18.

  10. If using the nut plates, starting in one corner of the template, place a nut plate 1 over the larger hole 2 drilled in step 9.

    The smaller hole 3 on the nut plate should line up with the smaller 3.6 mm (9/64 in.) hole on the template.

  11. If the smaller hole on the nut plate does not line up with the smaller hole on the template, mark the new hole location.
  12. Repeat steps 10 and 11 for each nut plate.
  13. Using a 3.6 mm (9/64 in.) drill bit, drill the smaller holes.
  14. Remove the template from the mounting surface.
  15. Starting in one corner of the mounting location, place a nut plate 4 on the back of the mounting surface, lining up the large and small holes.

    The raised portion of the nut plate should fit into the larger hole.

  16. Secure the nut plate to the mounting surface by fastening an included M3 screw 5 through the smaller 3.6 mm (9/64 in.) hole.
  17. Repeat steps 15 and 16 for each of the nut plates along the top and bottom of the device.
  18. Install the foam gasket 6 on the back of the device.

    The pieces of the foam gasket have adhesive on the back. Make sure you remove the protective liner before installing them on the device.

  19. If you will not have access to the back of the device after you mount it, connect all necessary cables and install microSD cards in the back of the device before placing it into the cutout.
    NOTE: To prevent corrosion of the metal contacts, cover unused connectors with the attached weather caps.
  20. Apply marine sealant between the mounting surface and the device to properly seal and prevent leakage behind the dashboard.
  21. If you will have access to the back of the device, apply marine sealant around the cutout.
  22. Place the device into the cutout.
  23. Secure the device to the mounting surface using the included M4 screws 7 or wood screws, depending on the mounting method.
  24. Carefully remove and discard the rubber protective bumper.
  25. Wipe away all excess marine sealant.
  26. Install the trim caps by snapping them in place over the screws.
