Bail Mounting the Device

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 any cracking in the gel-coat layer when the screws are
tightened.
The bail-mounting hardware (screws and washers, or nuts,
washers, and bolts) is not included. Before you can bail mount
the device, you must choose mounting hardware that fits the
holes in the bail mount bracket and securely attaches it to your
specific mounting surface. The size of the pilot holes required
depends on the mounting hardware you choose.

Flush Mounting the Device

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.
The included template and hardware can be used to flush mount
the device in your dashboard.
