1.2 Installation of Antenna Unit
Mounting considerations
Install the antenna unit referring to the installation diagram on page D-3 or D-4.
When selecting a mounting location for the antenna unit, keep in mind the follow-
ing points:
• Select a location out of the radar beam. The radar beam will obstruct or prevent
reception of the GPS satellite signal.
• The location should be well away from a VHF antenna.AGPS receiver is inter-
fered by a harmonic wave of a VHF antenna.
• There 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 recep-
tion or prolong acquisition time.
• Mount the antenna unit as high as possible. Mounting the antenna unit as high
as possible keeps it free of interfering objects and water spray, which can inter-
rupt reception of GPS satellite signal if the water freezes.
• The length of the whip antenna for the GP-1850DF should be no longer than
1.2 meter to prevent antenna damage. Do not use a 2.5 meter whip antenna.
• If the antenna cable is to be passed through a hole which is not large enough to
pass the connector, you may unfasten the connector with a needle nose pliers
and 3/8-inch open-end wrench. Refasten it as shown in Figure 1-4 after run-
ning the cable through the hole.

1.3 Installation of Transducers
Installing the inside-hull mount transducer
Necessary tools
You will need the following tools:
• Sandpaper (#100)
• Silicone sealant
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 single-hull thickness and
is void of air or flotation materials other than solid fiberglass between the trans-
ducer 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 proce-
dure for this is shown later.

If the bottom is displayed in red and the light-blue color appears the mounting
location is suitable. You can leave the transducer in position.
If the bottom is not displayed in reddish brown, the mounting location is unsuit-
able. 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
Support the transducer with a piece of wood to keep it in place wile it is drying. Let
the transducer dry 24–72 hours.

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 propel-
lers 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.
• Apracticalchoicewouldbesomewherebetween1/3and1/2oftheboat'slength
fromthestern. For planing hulls,apracticallocationisgenerallyrather 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.

Figure 1-15 Construction of fairing block
3. Drill a hole just large enough to pass the threaded stuffing tube of the trans-
ducer 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 mount-
ing 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 stuffingtubeandlocking nuts through excessivetight-
ening, 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.

1-11
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).
Flat Hull Deep V-hull

D>50 cm
Figure 1-16 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 trans-
ducerabout 5°attherear.Thismayrequirea certainamount
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 be-
cause 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 "satu-
ration" will be lengthened and performance will be reduced.
Do not paint the transducer. Performance will be affected.

Triducer 524ST-MSD, 525ST-MSD
The triducer is designed for thru-hull mounting.
Mounting considerations
When selecting a mounting location keep the following points 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 propel-
lers also adversely affects performance and the transducer should not be
