Fishnder 90/140 Owner’s Manual 11
Installing Your Fishnder
To mount the bracket assembly:
1. Using the tilt mount bracket (Fishnder 90) or the
swivel base (Fishnder 140; Fishnder 90 option) as a
template, mark the location of the three holes that you
use to secure the bracket to the mounting surface.
2. If securing the base with machine bolts, drill three 5/32"
holes at the locations you marked; or, if securing the
base using self-tapping screws, drill 1/16" starter holes
at the locations you marked. Drill starter holes no deeper
than half the screw length.
3. Secure the tilt mount bracket or swivel base with three
bolts or screws. DO NOT OVERTIGHTEN.
4. If you are using the swivel mount, place the swivel mount
bracket over the swivel base and secure it with the short
knob.
To install the Fishnder on the mount bracket:
1. Align the slot on the back of the Fishnder with the long
mounting knob, and slide the Fishnder into place. If
necessary, adjust the long knob to spread the bracket
arms apart. (Turn counter-clockwise to widen the bracket
arms and clockwise to tighten.)
2. Adjust the Fishnder angle, and tighten the long
mounting knob until snug.
3. For the Fishnder 140 (Fishnder 90 option), rotate
the swivel mount bracket by twisting it left or right. The
bracket clicks as you turn it. Select a good viewing
angle, and then tighten all knobs.
