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.

Important

It is the owner’s sole responsibility to install and use NA VMAN’ 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 inst allation: The choice, location and angle 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 cut are in a safe position and will not
weaken the boat’s structure. If in doubt, consult a qualified boatbuilder.

Position of transducer

Transom mount transducers are suit able for planing hulls less
than 26 ft (8 m) long, with outboard or stern-drive power. They
are unsuitable for boats with propellers forward of the transom,
prominent keels or displacement hulls.

Select a position for the transducer that will:

• Be away from the propellers or propeller wash and on the
downstroke side of the propeller/s (normally the starboard
side).

• Have a smooth, clear flow of water at all times, which
means that th e transducer should not be in line with
any hull projections, openings or planing strakes.

Important: Do not cut the transducer cable
to shorten it.

1 Select a suitable position for the

transducer (see

Position of transducer

-

previous page).

2 Tear the drilling template from inside the

back cover of this manual and cut to size.

3 Hold the drilling template in place on the

transom.
Mark four screw holes through the template

so that they will be positioned in the middle
of the transducer bracket’s slots:

• For fibreglass (GRP) or wooden hulls,

ensure the entire bottom face of the
transducer will always be
approximately 1/4" (6 mm) (dual
frequency transducer 1/2" (12 mm))
beneath the surface of the water ,
including when the boat is at speed.

• For aluminium hulls, ensure the entire

bottom face of the transducer will
always be approximately 1/2" (12 mm)
(dual frequency transducer 3/4" (18
mm)) beneath the surface of the water,
including when the boat is at speed.

Note: Locating the screws at the mid­points in the slots enables the transducer
to be moved up or down later.

4 Drill the four screw holes 5/64" (2 mm)

diameter and at right angles to the
transom, so that when the screws are
tightened the screw heads sit flat.

Installing

5 Attach the mounting bracket with the four

longer stainless screws provided, slide the
bracket up or down until the screws are in
the middle of the slots, then tighten the
screws temporarily.

6 If necessary , loosen the transducer pivot

bolt so that the transducer can rotate.

Note: the transducer rotates in ‘clicks’ of
7 degrees.

7 Hold a straight edge on the bottom of the

hull and rotate the transducer so that the
bottom surface of the transducer is parallel
to the bottom of the hull (to the closest click).

8 Push the end of the transducer down by one

click. Tighten the pivot bolt until the rubber
washer on the pivot bolt starts to compress,
then add another 1/4 turn. If the transducer
kicks up when at speed, then tighten the pivot
bolt more.

Note: The face of the transducer should
face forward by about 7 degrees when the
boat is moving.

• Always have the entire bottom face of the transducer under
water , when the boat is stopped or at speed.
Not interfere with, or be damaged by , launching or retrieving if the
boat is trailered.

Be convenient for the cable to go through the transom into the boat.

If the cable is to pass through the transom:

Drill the hole a safe
distance above water line.
If you are unsure where to
put the hole, consult a
qualified boatbuilder.
Do not cut the cable.

Fit cable cover over cable hole
in transom.

Fill the following with sealant:

• Cable hole in transom.

• Inside the cable cover.

• The screw holes.

Fit one or two cable clamps on transom to
hold cable.

Important: Fit a cable clamp close to the
transducer. This may prevent the
transducer from causing damage should
the bracket break while the boat is moving.

Cleaning and maintenance

The transducer has a cable to connect it to the
navigation instrument. When fitting this cable:

• Keep the cable away from other cables and
equipment (for example fluorescent lights,
power inverters and VHF transmitters).

• Do not cut the cable.

• If necessary , extend the cable by adding a
NA VMAN 13 f t (4 m) extension cable (a

maximum of one cable can be used).
Ensure no cable connectors lay in the bilge.

Note: There is no extension cable
available for the FISH 4100.

Secure the cable at regular intervals.
Refer to the navigation instrument’s
installation manual for instructions on how
to connect the cable to the instrument.

Wiring

Adjust and test the transducer after the
transducer and instrument have been installed
and with the boat in at least 6 ft (2 m) of water .
1 With the boat moving slowly , turn the

instrument on. If the depth does not
display, follow the troubleshooting
instructions in the instrument manual.

2 Gradually increase boat speed. If the

depth does not display then:
i Remove any oil from the transducer by

wiping the face of the transducer with
mild detergent on a cloth.

ii Adjust the angle of the transducer by

pushing the end down another click.

iii Loosen the screws then slide the

transducer mounting bracket down or
up in steps of 0.1" (2.5 mm) to achieve

best high speed performance. Several
adjustments might be required to find
the optimum position.

i v Review the position of the transducer

(see

Position of transducer

at the

beginning of this manual).

3 Once adjustments are completed, ensure

that all screws are tight, the pivot bolt is
tight and all holes are filled with sealant.

Note i: If the transducer kicks up at high
speed then the pivot bolt needs to be tighter.
Note ii: If you find that your transducer is
causing a ‘Rooster tail’ then the likely
cause is the transducer being mounted too
deep. Lifting the transducer mounting on
the transom should solve the problem.

Adjusting and testing

Clean a transducer with a damp cloth or mild detergent. A void abrasive cleaners and petrol or other
solvents. When repainting the hull, cover or remove any transducers. Do not paint the transducer . Do
not use a high pressure water blast on a speed sensor paddlewheel as it may damage the bearings.
