Basic installation tasks that you must perform include the following:
• Install the control head (choose gimbal or in-dash mounting, where
in-dash mounting requires a separate purchase)
• Install the transducer (choose the installation method that matches
your transducer) 6. Set the gimbal bracket aside and drill the four mounting screw holes using a

NOTE: Due to the wide variety of hulls, only general instructions are presented in this
installation guide. Each boat hull represents a unique set of requirements that should be
evaluated prior to installation. It is important to read the instructions completely and
understand the mounting guidelines before beginning installation.
SUPPLIES: In addition to the hardware supplied with your transducer, you will need a
powered hand drill and various drill bits, various hand tools, including a ruler or
straightedge, a level, a 12" plumb line (weighted string or monofilament line), marker or
pencil, safety glasses and dust mask, and marine-grade silicone sealant.
NOTE: When drilling holes in fiberglass hulls, it is best to start with a smaller bit and use
progressively larger drill bits to reduce the chance of chipping or flaking the outer coating.

allow for overhead mounting. The chosen mounting area should allow for
sufficient room so the control head can pivot through the full tilt range and allow
for easy removal and installation. 1
NOTE: You can drill the cable pass hole underneath the gimbal bracket, allowing you
to thread the cables through the knock-out holes in the mount; however, if you cannot
drill the hole directly under the mounting bracket, then you will need to drill the cable
pass hole behind the bracket, and will need to mount the hole cover there instead.
NOTE: When drilling holes in fiberglass hulls, it is best to start with a smaller bit and
use progressively larger drill bits to reduce the chance of chipping or flaking the outer
coating. Fill all holes with marine grade silicone sealant.
NOTE: You must have underside access to the mounting location to pass the cables
through to the surface. Also, make sure that the mounting surface is adequately
supported to protect the control head from excessive wave shock and vibration and 3

2 Connecting the Control Head Power Cable to the Boat
A 6' (2 m) long power cable is included to supply power to the control head. You
may shorten or lengthen the cable using 18 gauge multi-stranded copper wire.
CAUTION! Some boats have 24 or 36 Volt electric systems, but the control head
MUST be connected to a 12 VDC power supply.
The control head power cable can be connected to the electrical system of the
boat at one of two places: a fuse panel usually located near the console, or
directly to the battery.

TRANSOM TRANSDUCER
INSTALLATION
1.
Locating the Transducer Mounting Position
Turbulence: You must first determine the best location on the transom to install the
transducer. It is very important to locate the transducer in an area that is relatively
free of turbulent water. Consider the following to find the best location with the
least amount of turbulence: 2. Place the two ratchets, one on either side of
• As the boat moves through the water, turbulence Areas of Possible Turbulence
is generated by the weight of the boat and the
thrust of the propeller(s) - either clockwise or
counter-clockwise. This turbulent water is
normally confined to areas immediately aft of ribs,
strakes or rows of rivets on the bottom of the boat,
and in the immediate area of the propeller(s).
Clockwise propellers create more turbulence on
the port side. On outboard or inboard/outboard

TROLLING MOTOR
TRANSDUCER OPTIONS
• You may purchase a Trolling Motor Adapter kit that will allow you to mount
the transducer on the trolling motor.
• You may also exchange your NEW and UNASSEMBLED transducer (with
mounting hardware included) for a trolling motor transducer.
There are also several transducer switches available that support the following
configurations:
• Two control heads with one transducer
• Two transducers with one control head
TEST THE SYSTEM INSTALLATION
After you have completed the installation of the control head and any other
accessories, and have made all the required cabling connections, you must test
the installation before using the system.
1. Press the POWER/LIGHT key on the control head. If the unit does not
power up, make sure that power is available.
2. While the Title screen is shown on the display, press the MENU key to
display the Start-Up Options menu. Press the UP or DOWN Cursor keys to
choose System Status, and press the RIGHT Cursor key to select it.
Self Test displays results from the internal diagnostic self test, including unit
serial number, Printed Circuit Board (PCB) serial number, software revision,
total hours of operation and the input voltage.
NOTE: If you wait too long, the system will default to whichever menu mode happens
to be highlighted, and you will have to start again.
3. Press the VIEW key once. Review the accessory connections on the
Figure 35a
Accessory Test View.
NOTE: The speed will be detected only if the paddlewheel has moved since the
control head has been powered up.
4. Press the VIEW key once. Review the GPS receiver status on the GPS
Diagnostic View. GPS Diagnostic View shows a sky chart and numerical data
from the GPS receiver. The sky chart shows the location of each visible GPS
satellite with its satellite number and a signal strength bar (dark gray bar =

WARNING! This product contains chemicals known to the State of California to cause
cancer and/or reproductive harm.
WARNING! This device should not be used as a navigational aid to prevent collision,
grounding, boat damage, or personal injury. When the boat is moving, water depth may
change too quickly to allow time for you to react. Always operate the boat at very slow speeds
if you suspect shallow water or submerged objects.
WARNING! Do not travel at high speeds with the unit cover installed. Remove the unit cover
before traveling at speeds above 20 mph.
