Preface
Warning: It is your sole responsibility to install and
use the instrument and transducer(s) in a manner that
will not cause accidents, personal injury or property
damage. Always observe safe boating practices.
Sonar performance: The accuracy of the sonar depth display can
be affected by many factors, including the type and location of the
transducer and water conditions. Never use this instrument to
gauge depth or other conditions for swimming or diving.
The choice, location, and installation of transducers and other
components of the system are critical to the performance of the
system as intended. If in doubt, consult your Navico dealer.
To reduce the risk of misusing or misinterpreting this instrument,
you must read and understand all aspects of the Installation and
Operation manuals. We also recommend that you practice all
operations using the built-in simulator before using this instrument
on the water.
Disclaimer: Navico Holding AS and its subsidiaries, branches and
affiliates disclaim all liability for any use of this product in a way that
may cause accidents, damage or that may violate the law.

Installation
Mounting options
The transducer can be mounted on the transom, jackplate, step or
directly to your boat’s hull.
ÚNote: Step and direct to hull mount requires the separately
sold ‘Direct/Step mount (Flush bracket)’ mounting bracket.
Use the following table to determine which mounting option is
best suited to your boat/installation preferences.
ÚNote: When mounting the transducer, make sure there is
nothing around the mounting location that could interfere
with its sonar beams.
ÚNote: If mounting where the transducer comes out of the
water, for example when the boat is on plane, the sonar will
not work while the transducer is out of the water.

StructureScan 3D Transducer mounting options
"Transommount(Transom
bracket)" on page 9
•Keeps transducer in the water when the
boat is on plane, allowing you to track
bottom at high speeds
•Transducer angle can be adjusted so it is
parallel with the water
•Transducer more likely to collide with
obstructions in the water and adds drag
to the boat
"Jackplatemount(Transom
bracket)" on page 10
•Transducer is not in the water when boat
is on plane; protects transducer and
prevents drag from transducer
•Transducer angle can be adjusted so it is
parallel with the water
•Allows you to mount transducer without
drilling holes in your boat
•Sonar does not track bottom when
transducer comes out of the water
"Stepmount(Transom
bracket)" on page 12
•Transducer is not in the water when boat
is on plane; protects transducer and
prevents drag from transducer
•Transducer angle can be adjusted so it is
parallel with the water
•Sonar does not track bottom when
transducer comes out of the water

Transom mount bracket assembly
The transom mount bracket assembly comes with four washers, two
bolts and two nuts.

ÚNote: Ensure the cable has been threaded through the
bracket before running the cable through the boat.
ÚNote: The inside washer must be placed in the groove on
the curved shield before putting the bolt through from the
outside.
Flush mount bracket assembly
To mount the transducer directly to the step (Direct Step mount),
use the flush mount bracket (sold separately).

Transducer angle
After mounting the transducer, make sure the transducer is adjusted
so it will be parallel with the waterline in both the horizontal and
vertical axis when moving at trolling speed.

Downscan Overlay
The StructureScan 3D transducer should be installed within
approximately 0.3 m (1 ft) of the broadband sounder transducer to
get optimum performance from the Downscan Overlay feature.
Downscan overlay feature performance could be degraded if the
StructureScan 3D transducer is too far away from the broadband
sounder transducer.

< 0.3m (1ft)
Transom mount (Transom bracket)
The transducer can be mounted on a transom bracket. With this
mounting option the transducer can be in the water when you are
on plane, or can be mounted so it is only in the water when you are
moving at trolling speed.
Transom mount (fiberglass) supplies (not included)
3 mm (1/8”) Drill bit (Transom
mount pilot holes)
Marine high-grade above- or
below-waterline sealant/
adhesive compound
Transom mount (aluminum hull) supplies (not included)
M4 Machine Screws Marine high-grade above- or
below-waterline sealant/
adhesive compound
Plastic isolating material such as King Starboard (prevents
corrosion between bracket and aluminum hull)
Installation | StructureScan 3D Transducer 9

To mount on transom using the transom bracket:
1. Choose a transducer location and then route the transducer
cables through the bracket and to the location where the
module will be installed.
2. Place the transducer bracket against the transom and then align
the bottom of the transducer with the bottom of boat. Use a
pencil to mark the pilot holes through the slots in the
transducer bracket.
3. Drill the pilot holes into the boat’s transom.
4. Apply a marine high-grade above- or below-waterline sealant/
adhesive compound to the pilot holes.
5. Align the bracket slots over the pilot holes and fasten the
bracket to the transom using the supplied screws.
6. To make adjustments to transducer position, loosen the screws
and slide bracket up or down.
7. Connect the transducer cables to the module sonar ports.
After the transducer is connected and your boat is in the water, turn
on the Flip Left/Right feature in your display unit to ensure what is
shown on the left and right side on your display corresponds with
what is on the left and right side of your boat. Refer to your display
unit's Operation manual for more information.
Jackplate mount (Transom bracket)
The transducer transom bracket can be mounted inside or outside
of the jackplate by drilling through the jackplate and then running
bolts through the hinge hole in the side of the bracket into the
jackplate. The illustration above shows the transom bracket
mounted inside the jackplate.
ÚNote: Sonar does not track bottom when the transducer is
out of the water.
