Tilt mount bracket
To mount the bracket assembly:
1. Using the tilt mount bracket (Fishfinder 90) or the
swivel base (Fishfinder 140; Fishfinder 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 Fishfinder on the mount bracket:
1. Align the slot on the back of the Fishfinder with the
long mounting knob, and slide the Fishfinder 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 Fishfinder angle, and tighten the long
mounting knob until snug.
3. For the Fishfinder 140 (Fishfinder 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.
