Installing the Unit on the Mount Bracket

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.

Installing the Wiring Harness

The Fishfinder comes with a wiring harness that connects
the Fishfinder to power and the transducer with one easy-
to-remove connection. If it is necessary to extend the power
wires, use 22 AWG wire. DO NOT cut the transducer
cable, because this voids your warranty. If your boat has an
electrical system, you might be able to wire the Fishfinder
directly to an unused holder on your current fuse block. If
you are using the boat's fuse block, remove the in-line fuse
holder supplied with the Fishfinder. You can also wire the
Fishfinder directly to the battery.
CAUTION: The Fishfinder input voltage is 10–18
volts DC. Do not exceed this voltage, because this can
damage the Fishfinder and void the warranty.
To install the wiring harness:
1. Determine the polarity of the power source using a
test light or volt meter.
2. Install the red (+) wire on the positive fuse holder or
battery terminal.
