1.2 Installation of Standard Equipment
Installing the display unit
Mounting considerations
The display unit can be installed on a tabletop or on the overhead.
When selecting a mounting location for the display unit keep the
following in mind:
• Keep the display unit out of direct sunlight.
• The temperature and humidity should be moderate and stable.
• Locate the unit away from exhaust pipes and vents.
• The mounting location should be well ventilated.
• Mount the unit where shock and vibration are minimal.
• Keep the unit away electromagnetic field generating equipment
such as motor, generator.
Cover
• For maintenance and checking purposes, leave sufficient space
at the sides and rear of the unit and leave slack in cables.
• A gyrocompass will be affected if placed too close to the display unit. Observe the following compass safe distances to prevent disturbance to the gyrocompass:
Standard compass: 0.7 meters
Steering compass: 0.6 meters

Mounting considerations
When selecting a mounting location for the antenna unit, keep in
mind the following points:
• Select a location out of the radar beam. The radar beam will
obstruct or prevent reception of the GPS satellite signal.
• Be sure the location offers a clean line-of-sight to satellite. Objects within line-of-sight to a satellite, for example, a mast or
funnel, block reception and cause prolonged acquiring time or
interruption of position fix.
• Mount the unit as high as possible. This will keep the unit free
of water spray, which can interrupt reception of GPS satellite
signal if frozen.
• Separate the unit well away from the antenna of radio equipment.

Antenna unit mounting procedure
You will need a medium size slotted-head screwdriver and vinyl
tape.
The standard antenna is usually fastened to a length of pipe and
fastened to a mast. (A mast mount fixture is optionally available
for this.) The threaded antenna base accepts a standard antenna
mount with a 1"-14 straight thread. Mount the antenna on a length
of pipe with a 1"-14 threaded end.
1. Pass the antenna cable through the pipe. Fasten the connector
on the cable to the antenna.

1.3 Installation of Transducers
Installing the inside-hull mount transducer
Necessary tools
You will need the following tools:
• Sandpaper (#100)
• Silicone sealant
• Silicone grease
Remarks on installation
• Do the installation with the boat hauled out of the water.
• Turn off the engine while installing the equipment.
• Install the transducer in the engine room.
Selecting the mounting location
Keep the following points in mind when selecting a mounting location:
• The mounting location should be where the hull is of singlehull thickness and is void of air or flotation materials other than
solid fiberglass between the transducer face and the water.
• Do not place the transducer over hull struts or ribes which run
under the hull.
• Avoid a location where the rising angle of the hull exceeds 15°,
to minimize the effect of the boat’s rolling.
• You will finalize the mounting location through some trial and
error. The procedure for this is shown later.

location is unsuitable. Relocate the transducer and do the
following.
1. Press the POWER key to turn off the power.
2. Gently dismount the transducer with piece of wood.
3. Do steps 1 through 5 in the previous procedure. Repeat until
a suitable location is found.
Final preparation

Installing the thru-hull mount transducer
Transducer mounting location
This type of mounting provides the best performance of all, since
the transducer protrudes from the hull and the effect of air bubbles
and turbulence neat the hull skin is reduced. When the boat has a
keel, the transducer should be at least 30 cm away from it. Typical
through hull mountings are shown in the figure on the next page.
The performance of the video 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:
• Air 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.
• The transducer must always remain submerged, even when the
boat is rolling, pitching or up on a plane at high speed.
• A 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 selected 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.
Installing the transom mount transducer
This type of mounting is very commonly employed, usually on
relatively small I/O 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).

Figure 1-23 Transom mount transducer mounting locations
Installing the transom mount transducer flush with hull (for
flat hulls)
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 tapping screws (supplied).
3. Adjust the transducer position so the transducer faces right to
the seabed.
Note: If necessary, to improve water flow and minimize air
bubbles staying on the transducer face, incline the transducer
about 5° at the rear. 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 projecting from
hull (for deep-V hulls)
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.
1.4 Installation of Optional Sensors
Through-hull mount water temperature/speed sensor
(ST-02MSB, ST-02PSB)
Select a suitable mounting location considering the following:
• Select a mid-boat flat position. The sensor does not have to be
installed perfectly perpendicular. The sensor must not be damaged in dry-docking operation.
• Select a place apart from equipment generating heat.
• Select a place in forward direction viewing from the drain hole
for cooling water.
• Select a place free from vibration.
1. Dry-dock the boat.
2. Make a hole of approx. 51 mm diameter.
3. Unfasten locknut and remove the sensor section.
4. Apply high grade sealant to the flange of the sensor.
5. Pass the sensor casing through the hole.
6. Face the notch on the sensor toward boat's bow and tighten the
flange.
7. Set the sensor section to the sensor casing and tighten the locknut.
8. Launch the boat and check for water leakage around the sensor.
