FCC Statement
Note: This equipment has been tested and found to comply with the limits for a Class
B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference in a normal installation.
This equipment generates, uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause harmful interference
to radio communications. However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does cause harmful interference to
radio or television reception, which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the interference by one or more of the
following measures:
Reorient or relocate the receiving antenna
Increase the separation between the equipment and receiver
Connect the equipment into an output on a circuit different from that to which the
receiver is connected
Consult the dealer or an experienced technician for help
A shielded cable must be used when connecting a peripheral to the serial ports.
Important
It is the owner’s sole responsibility to install and use Navman’s transducers in a manner that
will not cause accidents, personal injury or property damage. The user of this product is solely
responsible for observing safe boating practices.
Transducer installation: The choice, location, angle and installation of the transducer is the most
critical part of installation. If installation is not correct, the unit can not perform at its designed
potential. If in doubt, consult your Navman dealer. Ensure that any holes that cut are in a safe
position and will not weaken the boat’s structure. If in doubt, consult a qualifi ed boat builder.
Disclaimer: The information in this manual is provided as a guide only. The transducer’s
performance is infl uenced by the boat’s material, hull design and engine installation and these
are beyond the control of Navman NZ Limited.

NAVMAN
2-2 Installing a through hull transducer
1 Select a suitable position for the
transducer (see section 2-1).
If the hull panel is too thin or the panel
might not be strong enough, consider
fi tting a reinforcing pad on the inside of
the hull.
2 Find the hole size required for the
transducer from the table above. Drill or
cut the hole in the hull. The hole must be
perpendicular to the hull surface.
3 For an insertable transducer:
i remove the locking nut or pin
rom the fi tting
ii pull the transducer out from the
hull fi tting
iii unscrew the nut from the hull fi tting.
For a fi xed transducer:
i unscrew the nut from the hull fi tting
ii hold the nut just inside the hole
in the hull
iii feed most of the transducer cable
through the hole in the hull (from the
outside) and through the nut.
4 Apply a thick layer of fl exible bedding
compound (such as Sikafl ex) to the
2-1 Positioning a through hull transducer
This transducer will be fi tted in a hole drilled
in the bottom of the boat. Select a position
for the transducer that has a smooth fl ow of
clear water over the transducer surface at all
times. This means that the transducer should
be ahead of any keel, hull projections, hull
openings, paddle wheel transducers, propellers
or propeller wash. If the bottom of the boat is
painted and the boat has been used, do not
mount the transducer where the paint is eroded
(an indication of turbulence).
In addition, position the transducer:
as close to the middle line of the hull as
possible and as deep as possible
where the deadrise angle is small
with suffi cient space inside the hull for
access and wiring
so that it will not interfere with launching
or retrieving the boat
Ideally a depth transducer should be fi tted so
that its axis is vertical, however it can be up to
15° off vertical.

and on the exterior threads where they
pass through the hull.
5 Insert the hull fi tting into the hull from
outside. For a speed/temperature
transducer, rotate the fi tting until the arrow
on the outside lip points forward to within 5°.
6 Fit and tighten the nut on the hull fi tting.
For a plastic fi tting, hand-tighten the nut
and do not over tighten. For a bronze
fi tting, tighten with slip-joint pliers.
Tighten the nut until excess bedding
compound is squeezed out from under
the nut and the face of the hull fi tting.
Remove the excess bedding compound.
7 For a speed/temperature transducer,
check that the arrow on the hull fi tting still
points forward.
8 For an insertable transducer:
i ensure there is a thin layer of silicone
grease or O-ring lubricant on the
transducer O-rings
ii insert the transducer back into the hull
fi tting, rotating the transducer so that
the arrow on the transducer mates
with the notch on the fi tting
iii replace the locking nut or pin.
9 Wait for the bedding compound to dry.
10 Before leaving the boat unattended,
check that there is no water ingress
from around the transducer.

3 In-hull depth transducer
3-1 Positioning an in-hull transducer
This transducer will be glued to the inside of
the bottom of the boat. Select a position for the
transducer that has a smooth fl ow of clear water
under the transducer at all times. This means
that the transducer should be ahead of any keel,
hull projections, hull openings, paddle wheel
transducers, propellers or propeller wash. If
the bottom of the boat is painted and the boat
has been used, do not mount the transducer
where the paint is eroded (an indication of
turbulence).
In addition, position the transducer:
as close to the middle line of the hull as
possible and as deep as possible
with suffi cient space inside the hull for
access and wiring
where the inside surface of the hull is fl at and
smooth and there will be no gaps between
the face of the transducer and the hull.

One in-hull transducer is available, a depth transducer.
Caution
In-hull depth transducers are only suitable for solid GRP hulls up to ¾" (20 mm) thick, without air
pockets, beads or voids. They are not suitable for wooden, metal or sandwich hulls. Compared to
other types of transducer, in-hull depth transducers generally have lower performance because
power is absorbed in the hull.
No Yes
Ideally the transducer should be rotated so
that its axis is vertical, however it can be up
to 15° off vertical.
The face of the transducer is angled. When
fi tting the transducer, rotate the transducer so
that the axis of the transducer is as close to
vertical as possible.
9Through hull & In-hull transducer installation manual
NAVMAN
1 Select a suitable position for the
transducer and establish how the
transducer should be rotated so that the
axis is as vertical as possible (see section
2-1).
2 Test the transducer at this position
with the boat in the water before
mounting it permanently:
i Partially fi ll a thin plastic bag with
water, place the transducer inside and
close it tightly around the cable
with a tie-wrap.
ii Install the depth instrument as
described in the instrument’s
Installation and Operation manual.
iii Wet the surface of the hull and press
the transducer against the inside of
the hull where you plan to mount the
transducer.
iv Check that the instrument measures
depth correctly and consistently, up
to the maximum depth specifi ed for
the instrument. If necessary, move the
bag around the hull to fi nd the best
position.
3 Choose an adhesive or sealant to glue
the transducer to the hull. Hard epoxies
transmit the transducer signals best but
temperature changes and hull fl exing can
cause delamination. As a compromise,
use a viscous slow cure, fairly rigid epoxy
or Sikafl ex 252 sealant.
3-2 Installing an in-hull depth transducer
4 Ensure the inside of the hull where the
transducer will be mounted is fl at.
Clean, degrease and dry:
the inside of the hull where the
transducer will be mounted
the sloping face of the transducer
5 Fit the transducer:
i Apply the epoxy or sealant to the
middle of the transducer face.
ii Press the transducer into place
on the hull.
iii Twist the transducer back and forth to
expel any trapped air and to expel as
much glue as possible from the joint.
The fi nished joint should be as thin as
possible and not contain any
air bubbles.
Leave the transducer rotated to the
correct angle.
iv Temporarily secure the transducer in
place with tape and wait for the glue
to cure for 24 hours.
