1. MOUNTING

1.1 Mounting considerations

When selecting a mounting location, keep the following points in mind:

• Install the units indoors.

• Locate the units away from water splash.

• The operating temperature range of the processor unit is -15°C to 55°C (-27°F to

99°F). Be sure the mounting location satisfies this requirement.

• Locate the units away from exhaust pipes and vents.

• The mounting locations should be well ventilated.

• Mount the units where shock and vibration are minimal.

• Keep the units away from electromagnetic field-generating equipment such as mo-

tors and generators.

• Referring to the outline drawings at the back of this manual, leave sufficient room

for service and maintenance. Also, leave slack in cables for maintenance and ser-

vicing ease.

• A magnetic compass may receive interference if it is placed too close to these units.

Observe the compass safe distances noted in the safety instructions to prevent in-

terference to the magnetic compass.

• The processor unit is equipped with an internal LAN antenna and should be in-

stalled in a location where the signal is not interrupted or halted by obstructions.

If you cannot install the processor in an obstruction-free location, connect the

processor unit to a wireless LAN router via LAN cable to establish an ETHERNET

connection.

1.4 How to Install Transducers

Note: For configurations using the DFF-3D, see the DFF-3D installation instructions

in the operator’s manual (OME-13520-xx; xx indicates publication version).

1.4.1 How to install a transducer through the hull

Transducer mounting location

The thru-hull mount transducer provides the best performance of all, since the trans-

ducer protrudes from the hull and the effect of air bubbles and turbulence near the hull

skin is reduced. If your boat has a keel, the transducer should be at least 30 cm away

from it.

The performance of this fish finder is directly related to the mounting location of the

transducer, especially for high-speed cruising. The installation should be planned in

advance, keeping the length of the transducer cable 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 ad-

versely 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 your 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.

Installation procedure

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 un-

disturbed 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 locknut. 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 locknut 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 re-tightened several days after the

boat has been launched.

Transducer preparation

Before putting your 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.

1.4.2 How to install a transducer in the transom

The optional transom mount transducer is very commonly employed, usually on rela-

tively 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.

DO NOT over-tighten screws, to prevent damage to the transducer.

Installation procedure

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 for self-tapping screw (5u20) in the mounting location.

2. Coat the threads of the self-tapping screws (5x14) for the transducer with marine

sealant for waterproofing. Attach the transducer to the mounting location with the

self-tapping screws.

3. Adjust the transducer position so the transducer faces right to the bottom. If nec-

essary, 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. Tape the location shown in the figure below.

5. Fill the gap between the wedge front of the transducer and transom with epoxy

material to eliminate any air spaces.

6. After the epoxy hardens, remove the tape.

1.4.3 How to install a transducer from inside the hull

The transducer may also be installed inside the hull on FRP boats. However, this in-

stallation method affects the ability to detect the seabed, fish and other objects be-

cause the ultrasound pulse is weakened when it passes through the hull.

Note: This mounting method should not be used to mount transducers that support

the RezBoost

™

, ACCU-FISH

™

and/or Bottom Discrimination Display feature, since

performance is greatly degraded.

Necessary tools

The following tools are required:

Remarks on installation

Installation procedure

The attenuation of the ultrasound pulse varies with the thickness of the hull. Select a

location where attenuation is the lowest.

1. Select 2-3 locations considering the four points mentioned below.

2. Decide the most suitable site from the locations selected.

1) Connect the power cable and transducer cable to the display unit.

2) Put the transducer into water-filled plastic bag. Press the transducer against

the chosen site.

3) Tap (power switch) to turn the power on.

4) After the startup procedure completes (approx. 90 seconds), the last used dis-

play appears. Tap the [Home] icon to show the home screen and display

mode settings. See section 3.3 for how to use the menu.

5) Drag the menu to show [Sounder] in the menu, then tap [Sounder].

6) Drag the [Sounder] menu to show the [SOUNDER INITIAL SETUP] menu.

7) Tap [Fish Finder Source].

• Sandpaper (#100)

• Marine sealant

• Water-filled plastic bag

• Do the installation with the ship moored at a dock, etc. The water depth should be 6.5

to 32 feet (2 to 10 meters).

• Turn off the engine.

• Do not power the unit with the transducer in the air, to prevent damage to the trans-

ducer.

• Do not use this method on a double layer hull.

• Before attaching the transducer to the hull, check that the site is suitable, by following

steps 1 to 3 in the installation procedure below.

• Mount the transducer at a location 1/2 to 1/3 of the length of your boat from the stern.

• The mounting location is between 15 to 50 cm from the centerline of the hull.

• Do not place the transducer over hull struts or ribs 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.

3. Remove the transducer from the plastic bag and wipe the face of transducer with

a cloth to remove water and any foreign material. Lightly roughen the face with

#100 sandpaper. Also, use the sandpaper to roughen the inside of the hull where

the transducer is to be mounted.

4. Wipe off any sandpaper dust from the face of the transducer.

5. Dry the face of the transducer and the hull. Coat the transducer face and mounting

location with marine sealant. Hardening begins in approx. 15 to 20 minutes so do

this step without delay.

6. Attach the transducer to the hull. Press the transducer firmly down on the hull and

gently twist it back and forth to remove any air which may be trapped in the marine

sealant.

7. Support the transducer with a piece of wood to keep it in place while the sealant

is drying. It takes 24 to 72 hours to harden completely.

Mounting location

To ensure the best performance, the sensor must be submerged in aeration-free and

turbulence-free water. Mount the sensor close to the centerline of your boat. On slow-

er heavier displacement hulls, positioning it farther from the centerline is acceptable.

Allow adequate space above the bracket for it to release and rotate the sensor up-

ward.

Note 1: Do not mount the sensor in an

area of turbulence or bubbles: near water

in-take or discharge openings; behind

strakes, struts, fittings, or hull irregulari-

ties; behind eroding paint (an indication of

turbulence).

Note 2: Avoid mounting the sensor where the boat

may be supported during trailering, launching, haul-

ing, and storage.

Note 3: For single drive boat, mount on the star-

board side at least 75 mm (3") beyond the swing ra-

dius of the propeller, as shown in the right figure.

Note 4: For twin drive boat, mount between the

drives.

How to install the bracket

1. Cut out the installation template (enclosed with transducer) along the dotted line.

2. At the selected location, position the template, so the arrow at the bottom is

aligned with the bottom edge of the transom. Being sure the template is parallel

to the waterline, tape it in place.

Warning: Always wear safety gog-

gles and a dust mask.

3. Using a 4 mm, #23, or 9/64” bit, drill

three holes 22 mm (7/8”) deep at

the locations indicated. To prevent

drilling too deeply, wrap masking

tape around the bit 22 mm (7/8”)

from the point.

Fiberglass hull: Minimize surface cracking by chamfering the gelcoat. If a cham-

fer bit or countersink bit is not available, start drilling with a 6mm or 1/4” bit to a

depth of 1 mm (1/16”).

4. If you know your transom angle, the bracket is designed for a standard 13° tran-

som angle.

• 11° to 18° angle: No shim is required. Skip to step 3 in "Adjustments".

• Other angles: The shim is required. Skip to step 2 of "Adjustments".

If you do not know the transom angle, temporarily attach the bracket and sensor

to the transom to determine if the plastic shim is needed.

5. Using the three #10 x 1-1/4” self-tapping screws, temporarily screw the bracket to

the hull. DO NOT tighten the screws completely at this time. Follow the step 1-4

in "How to attach the sensor to the bracket", before proceeding with "Adjust-

ments".

Adjustments

1. Using a straight edge, sight the underside of the sensor relative to the underside

of the hull. The stern of the sensor should be 1-3 mm (1/16-1/8”) below the bow

of the sensor or parallel to the bottom of the hull.

Note: Do not position the bow of the sensor lower than the stern because aeration

will occur.

2. To adjust the sensor's angle relative to the hull, use the tapered plastic shim pro-

vided. If the bracket has been temporarily fastened to the transom, remove it. Key

the shim in place on the back of the bracket.

2°-10° transom angle (stepped transom and jet boats): Position the shim with

the tapered end down.

19°-22° transom angle (small alumi-

num and fiberglass boats): Position

the shim with the tapered end up.

3. If the bracket has been temporarily fas-

tened to the transom, remove it. Apply

marine sealant to the threads of the

three #10 x 1-1/4” self-tapping screws to

prevent water seeping into the transom.

Screw the bracket to the hull. Do not

tighten the screws completely at this

time.

4. Repeat step 1 to ensure that the angle

of the sensor is correct.

Note: Do not position the sensor farther

into the water than necessary to avoid

increasing drag, spray, and water noise and reducing boat speed.

5. Using the vertical adjustment space on the bracket slots, slide the sensor up or

down to provide a projection of 3 mm (1/8”). Tighten the screws.

How to attach the sensor to the bracket

1. If the retaining cover near the top of the brack-

et is closed, open it by depressing the latch

and rotating the cover downward.

2. Insert the sensor's pivot arms into the slots

near the top of the bracket.

3. Maintain pressure until the pivot arms click

into place.

4. Rotate the sensor downward until the bottom

snaps into the bracket.

5. Close the retaining cover to prevent the acci-

dental release of the sensor when your boat is

underway.

How to route the cable

Route the sensor cable over the transom, through a drain hole, or through a new hole

drilled in the transom above the waterline.

Never cut the cable or remote the connector; this will void the warranty. Always wear

safety goggles and a dust mask.

1. If a hole must be drilled, choose a location well above the waterline. Check for ob-

structions such as trim tabs, pumps, or wiring inside the hull. Mark the location

with a pencil. Drill a hole through the transom using a 19 mm or 3/4” bit (to accom-

modate the connector).

2. Route the cable over or through the transom.

3. On the outside of the hull secure the cable against the transom using the cable

clamps. Position a cable clamp 50 mm (2") above the bracket and mark the

mounting hole with a pencil.

4. Position the second cable clamp halfway between the first clamp and the cable

hole. Mark this mounting hole.

5. If a hole has been drilled in the transom, open the appropriate slot in the transom

cable cover. Position the cover over the cable where it enters the hull. Mark the

two mounting holes.

6. At each of the marked locations, use a 3 mm or 1/8” bit to drill a hole 10 mm (3/

8”) deep. The prevent drilling too deeply, wrap masking tape around the bit 10 mm

(3/8”) from the point.

7. Apply marine sealant to the threads of the #6 x 1/2” self-tapping screw to prevent

water from seeping into the transom. If you have drilled a hole through the tran-

som, apply marine sealant to the space around the cable where it passes through

the transom.

8. Position the two cable clamps and fasten them in place. If used, push the cable

cover over the cable and screw it in place.

9. Route the cable to the display unit being careful not to tear the cable jacket when

passing it though the bulkhead(s) and other parts of the boat. To reduce electrical

interference, separate the sensor cable from other electrical wiring and "noise"

sources. Coil any excess cable and secure it in place with cable ties to prevent

damage.

2.2 How to Protect the Interface Connections

All cable connectors not inside the equipment, whether exposed to weather or other-

wise, should be waterproofed and secured after making the connection. By securing

and waterproofing the connections, the IPx2 rating can be maintained. Disconnec-

tions/loosened connections are also prevented.

To waterproof and secure each connection, refer to the procedures outlined below.

For completed connections

Self-vulcanizing tape

1) Wrap the connection, covering approx. 30 mm to either side, with self-vulcanizing tape.

2) Wrap a second layer of self-vulcanizing tape in the opposite direction.

Self-vulcanizing tape

3) Wrap vinyl tape over the self-vulcanizing tape.

The vinyl tape should cover approx. 50 mm to either side of the connection.
