1.2 How to Install the Sonar

This sonar can be installed on a deck or on a bulkhead. When selecting a mounting location, keep the following points in mind:

• Install the unit indoors.

• The operating temperature range of this unit is -15°C to 55°C (5°F to 131°F). Be sure the mounting location satisfies this requirement.

• 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 from electromagnetic field-generating equipment such as motors and generators.

• Observe the minimum recommended maintenance space shown in the outline drawing at the back of this manual. Also, leave slack in cables for maintenance and servicing ease.

• A magnetic compass may receive interference if it is placed too close to this unit. Observe the compass safe distances noted in the safety instructions to prevent interference to the magnetic compass.

• For mounting on a bulkhead, the connectors must face downward.

Fasten the unit to the mounting location with four self-tapping screws (5×20, supplied), referring to the outline drawing at the back of this manual for mounting dimensions.

1.3 Transducer

Thru-hull mount

The installation position of the transducer directly affects the performance of the transducer. For best performance, keep the following points in mind when selecting the mounting location.

• Select a location where the influence of water flow and air bubbles is minimal.

• Select a place least influenced by engine noise.

• Do not install the transducer inboard.

• For FRP vessel, do not cover the transducer with fiberglass, to prevent damage to the transducer if the temperature rises.

• Bottom slope angle less than 24°

The illustration below is the transducer with fairing, and was created by the Airmar Technology Corporation. The BOW mark (arrow) on the fairing and the triangular recess should be facing the bow.

• If the equipment is connected as shown in the figure below, change the time lag settings as indicated.

• If the connection is different from those mentioned here, calculate the time lag for each sensor and enter them accordingly, using the following formula. Time lag = Transmission delay + Propagation delay

Transmission delay: Delay required for calculation and output by the motion sensor, heading sensor, and position sensor. SC-30: Use 5 msec for the calculation. PG-700: Use 50 msec for the calculation. GP-330B: Use 50 msec for the calculation.

Propagation delay: Time required for the data to reach the DFF-3D, via repeater and data route. For the multi function display connected by CAN bus, use 15 msec for the calculation. If NMEA data is fed to the DFF-3D via the NMEA Data Converter (IF-NMEA2K2), set the calculation figure according to the baud rate between the sensor and the IF-NMEA2K2 as shown below. 38400 bps: Use 40 msec for the calculation. 4800 bps: Use 145 msec for the calculation.

For example, the sensor feeding data to the multi function display via the IFNMEA2K2 has a transmission delay of 30 msec and a baud rate of 38400 bps. Then, the time lag would be as shown in the calculation below. Time lag 70 msec = Transmission delay 30 msec + Propagation delay 40 msec

4.1.3 How to adjust the bottom range shift

The bottom range shift feature changes the location at which the seabed appears on the screen. This is particularly useful when the seabed is “off-screen”.

Note: This feature requires [Auto Range] to be active. See your respective Operator’s Manual for details.

Slide the slide bar at [Bottom Range Shift Area] (in the [Multi Beam Sonar] menu) to adjust the value as required. The following figure shows some examples of how the settings affect the on-screen display.

A lower value places the seabed at a higher location on-screen. A higher value places the seabed at a lower location on-screen.

4.1.4 How to change the transmission rate (PRR)

You can adjust the rate at which the sonar beam is transmitted (PRR, Pulse Repetition Rate) using one of the three available settings. Each setting has distinct characteristics allowing for a broad range of applications.

Setting Characteristics

[Manual] Affected by the selected range. A shorter range has a

faster transmission rate; a longer range has a slower rate.

[Auto] Affected by vessel speed. Slow speeds have a slower

transmission rate; high speeds have a faster rate. Note: Speeds of 20 kn or higher are fixed at a transmission rate of 20.

[Maximum] Affected by detected depth. Shallows have a faster trans-

mission rate; deeper waters have a slower rate. Note: Where the selected range exceeds the detected depth, the transmission rate may exceed 20.

1. From the [Multi Beam Sonar] menu, select [Transmit Rate Mode].

2. Select [Manual], [Auto] or [Maximum] as required.

3. If you selected [Manual], adjust the rate at [Transmit Rate Manual Value], using the slide-bar or the software keyboard. For [Auto] or [Maximum], go to step 4.

4. Close the menu.

Note: Adjustments made to the transmission rate also affect how the on-screen display appears for the Multi-Sounder and 3D Sounder History features. The following figures show examples of the same object and how the echo display is affected.

4.7 Personal Bethymetric Generator (PBG)

Note: This feature is available only for the NavNet TZtouch3 series (TZT9F, TZT12F,

TZT16F and TZT19F). Seabed maps recorded on a networked unit are not shared across the network. Use the file transfer functions of the TZT3, or record using each of the desired units.

The PBG feature creates a map of the seabed, colored according to recorded depth readings. An area of roughly twice the size of the depth is mapped, with the transducer as the center point. For example, a map of a 20 m deep seabed will be approximately 20 m wide to both port and starboard. Unlike 3D Sounder History, the color-mapped seabed appears on the plotter display.

Note: Tide data received from tidal stations is applied as an offset to show a depth which as close as possible to the actual depth.

Requirements

This feature is supported on all software versions of the DFF-3D provided the following requirements are met:

• Connection to a NavNet TZtouch3 using software version 2.01 or later.

• A micro SD card with sufficient blank space, inserted into the TZtouch3 unit.

Note 1: Chart cards may be used, provided sufficient free space is available.

Note 2: The data space required varies, depending on several factors, such as sea-

bed complexity, own ship speed and length of time spent mapping. The following cases, both based on a 24 hours period of recording, are intended as a reference for space required: A highly complex seabed, at depth of 200 m, traversed at a speed of 10 knots, with no overlaps in mapping area, uses approximately 13 MB. A shallow and relatively plain and flat seabed, traversed at a slow speed and with overlaps in the mapping area uses approximately 2 MB.

4-20

• Heading and positioning PGN data input to the NavNet TZtouch3.* Heading: 127237 (Heading/Track Control) or 127250 (Vessel Heading) or 130577 (Direction Data). Positioning: 129025 (Position, Rapid Update) or 129029 (GNSS Position Data).

*: FURUNO’s SC-33 or SCX-20, both boasting high quality positioning and relatively easy setup/synchronization, are recommended as a positioning/heading data source.

4.7.1 Setting up for PBG

To use the PBG feature, following settings must be completed in advance:

• Transducer initial settings, Motion Sensor initial settings, EPFs device (GPS antenna, etc.) initial settings. The procedure for these items are covered in the “HOW TO SET UP YOUR EQUIPMENT” chapter of your TZTouch3 Installation Manual.

• DFF-3D initial settings. See "Multi Function Display Initial Settings" on page 3-4.

• Sound speed adjustments. See "How to apply correction to the speed of sound" on page 4-11.

4.7.2 How to map the seabed

To start mapping, open the plotter screen, swipe the right edge of the screen inwards

to show the slide menu, then tap [PBG Recording]. The menu item changes to a yellow color, indicating that the feature is active. The coloration mode indicator also appears with a white background.

A thin blue line appears to the stern of the own ship icon. This line indicates the section of seabed being mapped. The length of the line changes according to depth; short for shallow waters, long for deep waters.

4. OPERATION

Note 1: Traveling over the same area more than once overwrites the previous seabed map with the latest scanned map. For this reason, avoid recording when the weather is inclement, or there is excessive roll/pitch, to avoid over-writing a clear map with a lower quality map.

Note 2: Depth is calculated and recorded with applicable adjustments made for tide height. Tide height is calculated based on the latest information received from Tide Stations.

To stop mapping, swipe the right edge of the screen inwards to show the slide menu, then tap [PBG Recording]. The menu item changes to a white color, indicating that the feature is inactive.

INSTALLATION INSTRUCTIONS

WARNING

Installation of the anti-rotation bolt is mandatory!

Depth Transducer

with Temperature Sensor &

High-Performance Fairing

Models: B54_SS54

Applications

• Bronze transducer recommended for fiberglass or wood hull.

• Stainless steel transducer compatible with all hull materials. Recommended for aluminum hulls to prevent electrolytic corrosion provided the stainless steel transducer is isolated from the metal hull.

• Maximum deadrise angle of 24°.

Follow the precautions below for optimal product performance and to reduce the risk of property damage, personal injury, and/or death.

WARNING: The transducer must be installed with a HighPerformance Fairing.

WARNING: When installing the High-Performance Fairing carefully follow these installation instructions.

WARNING: Always wear safety glasses, a dust mask, and ear protection when installing.

WARNING: The fairing must be installed parallel to the keel to ensure proper boat handling.

WARNING: Do not install a fairing that has been mis-cut. Replace it.

• Cutting the fairing at an angle greater than the maximum allowed will cut into the transducer and/or bolt pocket, thus weakening the fairing.

• Do not allow any gap between the fairing and the hull that is greater than 3mm (1/8"). When the boat is underway, water will enter any gaps and push against the fairing with considerable force, possibly rotating it.

WARNING: Immediately check for leaks when the boat is placed in the water. Do not leave the boat unchecked for more than three hours. Even a small leak may allow considerable water to accumulate.

CAUTION: Bronze transducer —Never mount a bronze transducer in a metal hull, because electrolytic corrosion will occur.

CAUTION: Bronze transducer —Never install a bronze transducer on a vessel with a positive ground system.

CAUTION: Stainless steel transducer in a metal hull— Use sleeving to isolate the stainless steel transducer and anti-rotation bolt from the metal hull. Failure to do so will cause electrolytic corrosion.

CAUTION: Never pull, carry, or hold the transducer by the cable as this may sever internal connections.

CAUTION: Never strike the transducer.

CAUTION: Do not over-tighten the hull nut and the nut on

the anti-rotation bolt, crushing the fairing and/ or hull.

CAUTION: The transducer and the yellow triangular plug must be flush with the fairing for smooth water flow under the transducer.

CAUTION: Never use solvents. Cleaner, fuel, sealant, paint, and other products may contain solvents that can damage plastic parts, especially the transducer’s face.

IMPORTANT: Read the instructions completely before proceeding with the installation. These instructions supersede any other instructions in your instrument manual if they differ.

The anti-rotation bolt holds the fairing firmly in place. Failure to install the antirotation bolt may result in the fairing rotating while the boat is underway. The effect may be violent movement and loss of steering. This could result in serious injury or death to passengers and/or damage to the boat or other property.

Mounting Location

CAUTION: Do not mount in line with or near water intake or

discharge openings or behind strakes, struts, fittings, or hull irregularities that will disturb the water flow.

• The water flowing under the hull must be smooth with a minimum of bubbles and turbulence (especially at high speeds).

• The transducer’s face must be continuously immersed in water.

• The transducer beam must be unobstructed by the keel or propeller shaft(s).

• Choose a location away from interference caused by power and radiation sources such as: the propeller(s) and shaft(s), other machinery, other echosounders, and other cables. The lower the noise level, the higher the echosounder gain setting that can be used.

• Choose a location with a minimum deadrise angle.

• Choose an accessible spot inside the vessel with adequate space for the height of the stem and tightening the nut.

Boat Types

(Figure 1)

• Displacement hull powerboat—Locate 1/3 of the way back along the LWL and 150– 300 mm (6–12") off the centerline. The starboard side of the hull where the propeller blades are moving downward is preferred.

• Planing hull powerboat—Mount well aft near the centerline and well inboard of the first set of lifting strakes to insure that it is in contact with the water at high speeds. The starboard side of the hull where the propeller blades are moving downward is preferred. Outboard and I/O—Mount just forward and to the side of the engine(s). Inboard—Mount well ahead of the propeller(s) and shaft(s). Stepped hull —Mount just ahead of the first step. Boat capable of speeds above 25kn (29MPH)—Review transducer location and operating results of similar boats before proceeding.

Installation

Cored Fiberglass Hull —Follow separate instructions on page 5.

Hole Drilling: Transducer

1. Drill a 3mm or 1/8" pilot hole perpendicular to the waterline from inside the hull (Figure 2). If there is a rib, strut or other hull irregularity near the selected mounting location, drill from the outside.

2. Using the appropriate size drill bit or hole saw, cut a hole from outside the hull. Be sure to hold the drill plumb, so the hole will be perpendicular to the water surface.

Cutting the High-Performance Fairing

CAUTION: The end of the fairing with the arrows/ triangular recess always points forward toward the bow when installed. Be sure to orient the fairing on the band saw, so the angle cut matches the intended side of the hull and not the mirror image.

1. Measure the deadrise angle of the hull at the selected mounting location using an angle finder (Figure 2). Check to be sure the angle does not exceed 24°.

2. Tilt the band saw table to the measured angle and secure the cutting fence (Figure 3). Do not exceed 24°.

3. Place the fairing on the table, so the cutting guide rests against the fence (Figure 4). The end with the arrows and triangular

recess will be pointing toward you for installation on the starboard side of the boat or away from you for installation on the port side.

4. Adjust the cutting fence, so the fairing will be cut in about two equal parts (Figure 3). The section that will become the fairing must be a minimum of 45mm (1-3/4") at its thinest dimension (Figure 2).

5. Recheck steps 1 through 4. Then cut the fairing.

6. When the boat is underway, especially at high speeds, water will enter any gaps and push against the fairing with considerable force, possibly rotating it. Shape the fairing to the hull as precisely as possible with a rasp or power tool. If there is a gap of more than 3mm (1/8"), replace the fairing.

7. Check to be sure the transducer is flush with the fairing. If it is recessed more than 0.5mm (1/64") inside the fairing, you may shim the transducer or carefully file/ sand the fairing.

8. The remaining section of the fairing with the cutting guide will be used as the backing block inside the hull. It will provide a level surface for tightening the nuts.

Hole Drilling: Anti-rotation Bolt

To locate and drill the hole for the anti-rotation bolt, use the fairing as a guide. This will ensure that the hole is perpendicular to the waterline and not drilled at the angle of the hull.

1. Dry fit the transducer in the fairing. Thread the cable through the large hole in the fairing and through the mounting hole in the hull. Seat the transducer firmly within the recess in the fairing (Figure 5 or 6). Be sure the arrow on the transducer points toward the triangular recess in the fairing.

2. Slide the transducer with the fairing in place into the mounting hole. Using the bolt hole in the fairing as your guide, drill a 3mm (1/8”) pilot hole through the hull for the anti-rotation bolt.

3. Using the appropriate size drill bit, hold the fairing in place and drill a hole for the anti-rotation bolt.

4. Remove the assembly and cable from the mounting hole.

5. Sand and clean the area around both holes, inside and outside, to ensure that the sealant will adhere properly to the hull. If there is any petroleum residue inside the hull, remove it with either mild household detergent or a weak solvent such as alcohol before sanding.

Metal hull—Remove all burrs with a file and sandpaper.

Bedding the Transducer

CAUTION: Be sure the surfaces to be bedded are clean and dry.

1. Remove the transducer from the fairing.

2. Apply a 2mm (1/16") thick layer of marine sealant to the surface of the transducer that will contact the fairing and up the stem (Figure 5 or 6, areas in red). The sealant must extend 6mm (1/4") higher than the combined thickness of the fairing, hull, backing block, and hull nut. This will ensure there is marine sealant in the threads to seal the hull and hold the hull nut securely in place.

Stainless steel transducer in a metal hull —To prevent electrolytic corrosion, the stainless steel housing must be isolated from the metal hull. Slide the isolation sleeve over the bedded transducer stem as far down as possible (Figure 6). Apply a 2mm (1/16") thick layer of the marine sealant to the outside of the sleeve.

3. Apply a 2 mm (1/16") thick layer of marine sealant to the following surfaces:

• Fairing that will contact the hull

• Backing block that will contact the inside of the hull

• Hull nut that will contact the backing block

4. Thread the transducer cable through the fairing and seat the transducer firmly within the recess. Be sure the arrow on the transducer points toward the triangular recess in the fairing.

Installing the Transducer

1. From outside the hull, thread the transducer cable through the mounting hole. Push the stem of the transducer (with the fairing in place) into the mounting hole using a twisting motion to squeeze out excess sealant (Figure 5 or 6). Be sure the arrow on the transducer points forward toward the bow.

NOTE: The transducer must be FLUSH with the fairing. If it is recessed more than 0.5mm (1/64") inside the fairing, you may shim the transducer or carefully file/ sand the fairing.

Stainless steel transducer in a metal hull —Be sure the isolation sleeve is between the transducer stem and the hull (Figure 6). However, the isolation sleeve must be below the washer and hull nut to prevent the sleeve from interfering with tightening the hull nut.

2. From inside the hull, slide the backing block onto the transducer cable and stem, seating the backing block firmly against the hull. Screw the hull nut in place, but do not tighten it at this time.

Bedding & Installing the Anti-rotation Bolt

CAUTION: Be sure the surfaces to be bedded are clean and dry.

1. Apply a 2 mm (1/16") thick layer of marine sealant to the antirotation bolt including the flange (Figure 5 or 6). The sealant must be 6mm (1/4") higher than the combined thickness of the fairing, hull, backing block, washer, and nut. This will ensure that there is marine sealant on the threads to seal the hull and hold the nut securely in place.

Stainless steel transducer in a metal hull—To prevent electrolytic corrosion, the stainless steel anti-rotation bolt must be isolated from the metal hull. Slide the isolation sleeve over the bedded anti-rotation bolt as far down as possible (Figure 6). Apply a 2mm (1/16") thick layer of the marine sealant to the outside of the sleeve.

2. Apply a 2 mm (1/16") thick layer of marine sealant to the side of the washer that will contact the backing block.

3. Push the anti-rotation bolt through the fairing and the hull.

4. From inside the hull, screw the washer (sealant side down) and the nut onto the anti-rotation bolt.

Stainless steel transducer in a metal hull—Be sure the isolation sleeve is between the anti-rotation bolt and the hull (Figure 6). However, the isolation sleeve must be below the washer and nut to prevent the sleeve from interfering with tightening the nut.

5. Use slip-joint pliers to tighten the hull nut. Then tighten the nut on the anti-rotation bolt. Do not over-tighten, crushing the

fairing or hull.

Cored fiberglass hull—Do not over tighten, crushing the hull. Wood hull—Allow for the wood to swell before tightening the nut.

6. Use marine sealant to half-fill the hollow in the yellow triangular plug. Apply a 2mm (1/16") thick layer of marine sealant to the three sides of the plug that form the triangle. The sealant will hold the plug firmly within the fairing and fill any gap between the anti-rotation bolt and the plug.

7. The yellow triangular plug fits one way only. Push the yellow plug into the recess in the fairing until it is FLUSH with the outside of the fairing. This will squeeze out excess sealant. If necessary, tap it into place with a mallet.

NOTE: If the triangular plug is slightly recessed within the fairing, use sealant to fill the gap. The plug must be FLUSH with the fairing for good performance.

8. When the boat is underway, especially at high speeds, water will enter any gaps and push against the fairing with considerable force, possibly rotating it. Fill any gaps between the fairing and the hull with marine sealant. If there is any gap greater than 3mm (1/8"), replace the fairing. Remove the excess sealant on the outside of the fairing and hull to ensure smooth water flow under the transducer.

Cable Routing & Connecting

CAUTION: If the sensor came with a connector, do not remove it

to ease cable routing. If the cable must be cut and spliced, use Airmar’s splash-proof Junction Box No. 33-035 and follow the instructions supplied. Removing the waterproof connector or cutting the cable, except when using a water-tight junction box, will void the sensor warranty.

1. Route the cable to the instrument being careful not to tear the cable jacket when passing it through the bulkhead(s) and other parts of the boat. Use grommet(s) to prevent chafing. To reduce electrical interference, separate the transducer cable from other electrical wiring and the engine. Coil any excess cable and secure it in place with cable ties to prevent damage.

2. Refer to the instrument owner’s manual to connect the transducer to the instrument.

Checking for Leaks

When the boat is placed in the water, immediately check around the transducer for leaks. Note that very small leaks may not be readily observed. Do not leave the boat in the water for more than 3 hours before checking it again. If there is a small leak, there may be considerable bilge water accumulation after 24 hours. If a leak is observed, repeat “Bedding” and “Installing” immediately (see page 4).

Installation in a Cored Fiberglass Hull

The core (wood or foam) must be cut and sealed carefully. The core must be protected from water seepage, and the hull must be reinforced to prevent it from crushing under the hull nut allowing the transducer to become loose.

CAUTION: Completely seal the hull to prevent water seeping into the core.

1. Drill a 3mm or 1/8" pilot hole perpendicular to the waterline from inside the hull (Figure 7). If there is a rib, strut, or other hull irregularity near the selected mounting location, drill from the outside. If the hole is drilled in the wrong location, drill a second hole in a better location. Apply masking tape to the outside of the hull over the incorrect hole and fill it with epoxy.

2. Using the appropriate size drill bit or hole saw, cut a hole from outside the hull through the outer skin only. Be sure to hold the

drill plumb, so the hole will be perpendicular to the water surface.

3. The optimal interior hole diameter is affected by the hull’s thickness and deadrise angle. It must be large enough in diameter to allow the core to be completely sealed.

Using the appropriate size drill bit or hole saw, cut through the inner skin and most of the core from inside the hull keeping the drill perpendicular to the hull. The core material can be very soft. Apply only light pressure to the hole saw after cutting through the inner skin to avoid accidentally cutting the outer skin.

4. Remove the plug of core material, so the inside of the outer skin and the inner core of the hull is fully exposed. Sand and clean the inner skin, core, and the outer skin around the hole.

5. Coat a hollow or solid cylinder of the correct diameter with wax and tape it in place. Fill the gap between the cylinder and hull with casting epoxy. After the epoxy has set, remove the cylinder.

6. Sand and clean the area around the hole, inside and outside, to ensure that the sealant will adhere properly to the hull. If there is any petroleum residue inside the hull, remove it with either mild household detergent or a weak solvent, such as alcohol, before sanding.

7. Follow the same procedure to prepare the hull for the antirotation bolt. Repeat steps 1 through 6.

8. Proceed with the installation beginning with "Cutting the Fairing" on page 3. Note that all holes are already drilled.

Anti-fouling Paint

Surfaces exposed to salt water must be coated with anti-fouling paint. Use water-based anti-fouling paint only. Never use ketonebased paint since ketones can attack many plastics possibly damaging the transducer. Reapply anti-fouling paint every 6 months or at the beginning of each boating season.

CAUTION: Do not mount the transducer in line with or near water intake or discharge openings or behind strakes, fittings, or hull irregularities that may disturb the water flow.

CAUTION: Do not mount the transducer in a location where the boat may be supported during trailering, launching, hauling, or storage.

• For best performance, the transducer’s face must be in contact with smooth water. To identify an area of “clean” water, observe the flow off the transom while the boat is underway.

• Allow vertical space above the bracket for it to release and rotate the transducer upward.

• Mounting the transducer on the side of the transom where the propeller blades are moving downward is preferred (Figure 1).

• Mount the transducer as far away from the propeller as possible while ensuring the transducer’s face remains in the water when the boat is turning.

Boat Types

• Single drive—Mount a minimum of 15 cm (6") beyond the

swing radius of the propeller (Figure 1).

• Twin drive—Mount between the drives a minimum of 15 cm

(6") beyond the swing radius of the propeller.

• Trim tabs—Mount inside the trim tab, space permitting.

• Stepped transom—Mount the transducer on the lowest step

being sure there is enough vertical space above the bracket for it to release and rotate the transducer upward (Figure 2).

Installation

Assembling the Transducer & Bracket

1. There are two cables. Thread each cable through the corresponding hole in the transducer support (Figure 3).

2. Fasten the support to the transducer using the three sockethead-cap screws and washers supplied. Tighten the screws with the 3/16" Allen wrench supplied.

3. Attach a safety ring to one end of each pin (Figure 4).

4. While holding the transducer assembly against the bracket, insert a pin through the upper hole in the bracket and the support. Slide the spacer onto the pin and push it through the remaining hole in the support and the bracket. Attach a second safety ring. This pin will function as a hinge when the transducer is released.

5. Slide a washer onto the remaining pin. Push it through the lower hole in the bracket, slide it along the channel in the support, and through the second hole in the bracket. Slide the second washer onto the free end of the pin and attach the second safety ring. This will function as the locking pin to hold the transducer in the operational position when underway.

Compensating for Transom Angle: Shims

For the best performance, the transducer beam must be aimed straight at the bottom. Since the transom of most boats is angled, the bracket must compensate for it. Measure the transom angle of the boat with an angle finder.

• Standard transom (12

transom angle)—The bracket is

designed for a standard 12

transom angle. No shim is needed for this installation. If your boat is capable of speeds above 20kn (28 MPH), install the bracket with one 3

shim, taper down. This will ensure that the transducer is in contact with the water at high speeds.

• Using shims—The bracket is supplied with three shims; each

one has a 3

angle. Up to three shims can be combined for a

maximum of 9

. The shims are designed to mate together. Two bosses on the face fit into recesses in the back of another shim or the holes in the bracket.

- Transom angles greater than 12

—Add the appropriate

number of shims with the taper up to the 12

bracket angle.

- Transom angles less than 12

—To reduce the bracket’s 12° angle, group the appropriate number of shims with the taper down.

• If you are unsure about using the shim(s), experiment with

them by following the instructions “Mounting & Adjusting the Bracket.”

Hole Drilling

CAUTION: To prevent drilling too deeply, wrap masking tape around the bit 22mm (7/8") from the point.

NOTE: Fiberglass hull—Minimize surface cracking by running the drill in reverse until the gelcoat is penetrated.

1. At the selected mounting location, position the assembly so the transducer projects 3mm (1/8") below the bottom edge of the transom (Figure 1). Be sure any shim(s) is in place. (You may want to tape the shim(s) to the bracket temporarily.) With the transducer in the operational position and the bracket parallel to the waterline, mark the bottom corners of the bracket.

2. Remove the transducer assembly from the bracket by removing the locking pin and the hinge pin (Figure 4). Hold the bracket with any shim(s) in place against the transom at the marked location. Draw an “X” at 12mm (1/2") from the top and the bottom of each slot (Figure 6).

3. Using a 5 mm, #4, or 7/32" drill bit, drill four holes 22mm (7/8") deep at the marked locations.

Mounting & Adjusting the Bracket

CAUTION: Do not position the leading edge of the transducer lower than the trailing edge because aeration will occur.

CAUTION: Do not position the transducer deeper in the water than necessary to avoid increasing drag, spray, and water noise and reducing boat speed.

CAUTION: The stainless steel bracket must be isolated from a metal hull to prevent electrolytic corrosion. If no shim is being used, place non-metal insulating washers between the bracket and the metal hull.

1. Apply marine sealant to the threads of four of the hex-washerhead screws to prevent water seepage into the transom. Being sure any shim(s) is in place, screw the bracket to the hull using a socket wrench (Figure 4). Do not tighten the screws at this time.

2. Reinstall the transducer. While holding the transducer assembly against the bracket, insert the hinge pin through the upper hole in the bracket and the support. Slide the spacer onto the pin and push it through the remaining hole in the support and the bracket. Reattach the safety ring.

3. Slide a washer onto the locking pin. Push it through the lower hole in the bracket, slide it along the channel in the support, and through the second hole in the bracket. Slide the second washer onto the free end of the pin and reattach the safety ring.

4. With the transducer in the operational position, use a straight edge to sight the underside of the transducer relative to the underside of the hull (Figure 5). The trailing edge of the transducer should be 1– 6mm (1/16–1/4") below the leading edge.

5. Using the vertical adjustment space in the bracket slots, slide the assembly up or down until the bottom inside corner of the transducer projections 0– 3mm (0–1/8") below the bottom of the hull (Figure 1). When you are satisfied with the position of the transducer, tighten the four bracket screws. For clear access to the screws, remove the transducer assembly from the bracket (Figure 4). When reattaching, be sure to include the spacer.

Testing on the Water

1. Test the transducer at 165 kHz with the engine off.

2. Become familiar with your echosounder’s performance at a speed of 4kn (5 MPH).

3. Gradually increase the boat speed and observe the gradual decline of performance due to turbulent water flowing under the transducer’s face.

NOTE: As the speed increases the performance at 50kHz will deteriorate more rapidly because more acoustic noise is generated at low frequencies.

4. If the decline in performance is sudden (not gradual), identify the boat speed at which the onset occurred. Return the boat to this speed, then gradually increase speed while making moderate turns in both directions.

5. If the performance improves while turning to the side on which the transducer is installed, its position probably needs adjustment. The transducer is probably in turbulent or aerated water.

To improve performance, try the following, one at a time, in the order given, in small increments. a. Increase the transducer’s angle in the water. Review

“Compensating for Transom Angle: Shims” and Figure 5.

b. Move the transducer deeper into the water in increments of

3mm (1/8") (Figure 1).

c. Move the transducer closer to the centerline of the boat.

Fill unused screw holes with marine sealant.

6. Calibration—To match the speed shown on the display to the actual speed of the boat, you may need to calibrate the instrument. Refer to your instrument owner’s manual.

Stabilizing the Bracket

1. Prevent the bracket from moving out of position using the remaining hex-washer-head screw. Drill the hole for the stabilizing screw through the center hole of the bracket, any shim(s), and the hull (Figure 6).

3. Fasten the stabilizing screw into place with a socket wrench. For clear access to the screw, remove the transducer assembly from the bracket (Figure 4). When reattaching the transducer, be sure to include the spacer.

Cable Routing & Connecting

CAUTION: Do not remove the connectors to ease cable routing. If

the cables must be cut and spliced, use Airmar’s splash-proof Junction Box No. 33-035 and follow the instructions provided. Removing the waterproof connectors or cutting the cables, except when using a water-tight junction box, will void the sensor warranty.

Route the cables over the transom for a detachable installation. For permanent mounting, route the cables through a drain hole or through new holes drilled in the transom above the waterline.

1. If holes must be drilled through the transom,

choose a location

well above the waterline (Figure 7). Check for obstructions such as trim tabs, pumps, or wiring inside the hull. Mark the locations with a pencil. Drill each hole using a 21mm or 13/16" bit to

accommodate the connector.

2. Route the cables over or through the transom.

3. On the outside of the hull, secure each cable against the transom using the cable clamps supplied. For the first cable, position one cable clamp 30cm (12") above the bracket. 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 through the transom, open the large slot in each transom cable cover. Position a cover over the cable where it enters the hull. Mark the two mounting holes.

6. For the second cable, repeat steps 3, 4, and 5.

7. At each of the marked locations, use a 3 mm or 1/8" bit to drill a hole 10mm (3/8") deep.

8. Apply marine sealant to the threads of the #6 x 1/2" self-tapping screws to prevent water from seeping into the transom. If you have drilled holes through the transom, apply marine sealant to the space around the cables where they pass through the transom.

9. Position the four cable clamps and fasten them in place. If used, push a cable cover over each cable and screw them in place.

10.Route the cables to the instrument being careful not to tear the cable jackets when passing it through the bulkhead(s) and other parts of the boat. Use grommet(s) to prevent chafing. To reduce electrical interference, separate the transducer cables from other electrical wiring and the engine(s). Coil any excess cable and secure it in place with cable ties to prevent damage.

11.Refer to your echosounder owner’s manual to connect the transducer to the instrument.

Checking for Leaks

When the boat is placed in the water, immediately check for leaks around the screws and any other holes drilled in the hull. Note that very small leaks may not be readily observed. Do not leave the boat in the water unchecked for more than three hours.

Maintenance

Anti-fouling Paint

Aquatic growth can accumulate rapidly on the transducer’s face reducing performance within weeks. Surfaces exposed to salt water that do not interlock must be coated with anti-fouling paint. Use water-based anti-fouling paint only. Never use ketone-based paint, since ketones can attack many types of plastic possibly damaging the transducer. Repaint every 6 months or at the beginning of each boating season.

Cleaning

CAUTION: Do not use a lubricant on the bracket; grit will stick to it, increasing friction and wear.

Clean the sensor with a Scotch-Brite

scour pad and mild household detergent, taking care to avoid making scratches on the transducer’s face. If the fouling is severe, lightly wet sand with fine grade wet/ dry paper.

Transducer Replacement & Parts

Lost, broken, and worn parts should be replaced immediately.

Please contact your Furuno dealer to obtain parts.
