1. INSTALLATION
NOTICE
Do not apply paint, anti-corrosive sealant
or contact spray to coating or plastic
parts of the equipment.
Those items contain organic solvents that
can damage coating and plastic parts,
especially plastic connectors.
1.1 Installation of Display Unit
The display unit may be mounted on a desktop, overhead or flush mounted in a console.
Mounting considerations
Choose a mounting location for the display unit considering the following points:
xChoose a location where the controls be easily operated.
xLeave sufficient maintenance space around the unit to facilitate checking and
maintenance. See the outline drawing at the back of the manual for recommended
maintenance space.
xLocate the unit out of direct sunlight because of heat that can build up inside the cabinet.
xThe operating temperature range is -15°C to 55°C (5°F to 131°F).
xLocate the unit well away from exhaust gases and other active gases.
xThe location should be well ventilated.
xChoose a location where shock and vibration are minimal.
xBe sure the mounting location is strong enough to support the weight of the unit,
particularly in overhead mounting. If necessary reinforce the mounting location.
xA magnetic compass will be affected if the display unit is placed too close to the compass.
Observe the following compass safe distances to prevent deviation to the compass.
Standard compass, 0.75 m, Steering compass, 0.50 m.

1.2 Installation of Antenna Unit
Refer to the antenna unit outline drawing at the back of this manual for mounting
instructions.
When selecting a mounting location consider the following points:
xSelect a location out of the radar and Inmarsat beams. Those beams will obstruct or
prevent reception of the GPS satellite signal.
xThere should be no interfering object within the line-of-sight to the satellites. Objects
within line-of-sight to a satellite, for example, a mast, may block reception or prolong
acquisition time.
xLocate the antenna well away from the antenna of a VHF radiotelephone to prevent
interference.
xMount the antenna unit as high as possible. Mounting it this way keeps it free of
interfering objects and water spray, which can interrupt reception of GPS satellite signal if
the water freezes.
If the antenna cable is to be passed through a hole in a bulkhead which is too small to pass
the connector, disassemble the connector with radio pincers and a monkey wrench. After
passing the cable through the hole assemble the connector as below.

1.3 Installation of Transducer
Inside-hull mounting
The thru-hull mount transducer (520-5PSD, 520-5MSD) may also be installed inside the hull,
following the procedure below.
Necessary tools
You will need the following tools:
xSandpaper (#100)
xMarine sealant
Remarks on installation
xTurn off the engine and anchor the boat while installing the equipment.
xInstall the transducer in the engine room.
xDo not turn on the echo sounder except if installing the transducer by the inside-hull
mounting method. The transducer may become damaged if the power is turned on in
other types of installations.
Choosing the mounting location
Keep the following points in mind when choosing a mounting location:
xThe mounting location should be where the hull is of single-hull thickness and is void of
air or flotation materials other than solid fiberglass between the transducer face and the
water.
xDo not place the transducer over hull struts or ribs which run under the hull.
xAvoid a location where the rising angle of the hull exceeds 15°, to minimize the effect of
the boat’s rolling.
xYou will finalize the mounting location through some trial and error. The procedure for this
is shown later.

Case 2
If the bottom is not displayed in reddish-brown, the transducer position is not suitable.
Change the location of the transducer. Further, refer to the operator’s manual to apply echo
offset in order to display the depth readout.
To change location of transducer:
1. Press the [POWER] switch to turn off the power.
2. Dismount the transducer. Insert knife or thin piece of wood between transducer and hull
to remove the transducer.
3. Follow steps 1-5 in “Checking the installation”. Reattach the transducer.
Note: If you are using the inner hull kit S (option) follow the instructions provided with the
kit.
Final preparations
Support the transducer with a piece of wood to keep it in place while the adhesive is drying.
Let the adhesive dry 24-72 hours.
Thru-hull mounting
Transducer mounting location
The thru-hull mount transducer (520-5PSD, 520-5MSD) provides the best performance of
all, since the transducer protrudes from the hull and the effect of air bubbles and turbulence
near the hull skin is reduced. When the boat has a keel, the transducer should be at least
30 cm away from it. Typical thru-hull mountings are shown in the figure on the next page.
The performance of this sounder is directly related to the mounting location of the
transducer, especially for high-speed cruising. The installation should be planned in
advance, keeping the standard cable length (8 m) and the following factors in mind:
xAir bubbles and turbulence caused by movement of the boat seriously degrade the
sounding capability of the transducer. The transducer should, therefore, be located in a
position where water flow is the smoothest. Noise from the propellers also adversely
affects performance and the transducer should not be mounted nearby. The lifting strakes
are notorious for creating acoustic noise, and these must be avoided by keeping the
transducer inboard of them.
xThe transducer must always remain submerged, even when the boat is rolling, pitching or
up on a plane at high speed.
xA practical choice would be somewhere between 1/3 and 1/2 of the boat’s length from the
stern. For planing hulls, a practical location is generally rather far astern, so that the
transducer is always in water regardless of the planing attitude.

Procedure for installing the thru-hull mount transducer
1. With the boat hauled out of the water, mark the location chosen for mounting the
transducer on the bottom of the hull.
2. If the hull is not level within 15° in any direction, fairing blocks made out of teak should
be used between the transducer and hull, both inside and outside, to keep the
transducer face parallel with the water line. Fabricate the fairing block as shown below
and make the entire surface as smooth as possible to provide an undisturbed flow of
water around the transducer. The fairing block should be smaller than the transducer
itself to provide a channel to divert turbulent water around the sides of the transducer
rather than over its face.

3. Drill a hole just large enough to pass the threaded stuffing tube of the transducer
through the hull, making sure it is drilled vertically.
4. Apply a sufficient amount of high quality caulking compound to the top surface of the
transducer, around the threads of the stuffing tube and inside the mounting hole (and
fairing blocks if used) to ensure watertight mounting.
5. Mount the transducer and fairing blocks and tighten the locking nuts. Be sure that the
transducer is properly oriented and its working face is parallel to the waterline.
Note: Do not over-stress the stuffing tube and locking nuts through excessive tightening,
since the wood block will swell when the boat is placed in the water. It is suggested
that the nut be tightened lightly at installation and retightened several days after the
boat has been launched.

11
Transom mount transducer
The transom mount transducer (520-5PWD) is very commonly employed, usually on
relatively small inboard/outboard or outboard boats. Do not use this method on an inboard
motor boat because turbulence is created by the propeller ahead of the transducer.
There are two methods of installation: flush with hull (for flat hulls) and projecting from hull
(for deep V-hulls).

Transom mount transducer mounting locations
Installing the transom mount transducer on a flat hull
A suitable mounting location is at least 50 cm away from the engine and where the water
flow is smooth.
1. Drill four pilot holes in the mounting location.
2. Attach the transducer to the bracket with 5 x 20 tapping screws (supplied).
3. Adjust the transducer position so the transducer faces right to the bottom.
Note: If necessary, to improve water flow and minimize air bubbles staying on the
transducer face, incline the transducer about 5° downward at the rear – loosen
the screws fixing the transducer, tilt the transducer and tighten screws. This may
require a certain amount of experimentation for fine tuning at high cruising
speeds.
4. Fill the gap between the wedge front of the transducer and transom with epoxy material
to eliminate any air spaces.

Installing the transom mount transducer on a deep-V hull
This method is employed on deep-V hulls and provides good performance because the
effects of air bubbles are minimal. Install the transducer parallel with water surface; not flush
with hull. If the boat is placed on a trailer care must be taken not to damage the transducer
when the boat is hauled out of the water and put on the trailer.

Transducer preparation
Before putting the boat in water, wipe the face of the transducer thoroughly with a detergent
liquid soap. This will lessen the time necessary for the transducer to have good contact with
the water. Otherwise the time required for complete “saturation” will be lengthened and
performance will be reduced.
DO NOT paint the transducer. Performance will be affected.
