Installation Overview

Following are instructions for the installation of this accessory. Before you start installation, we encourage you to read

these instructions carefully in order to get the full benefit from your Humminbird® accessory.

If you find that any items are missing from your installation kit, call our Customer Resource Center at 1-800-633-1468

or visit our Web site at humminbird.com.

NOTE: This type of transducer installation is not recommended for trailerable boats.

NOTE: This transducer requires drilling a hole in the hull of the boat; therefore, installation should be performed by a

qualified marine technician.

In addition to the hardware supplied with your transducer, you will need a drill, a small drill bit for a pilot hole, a

1 1/8" hole saw, a level, and marine-grade silicone sealant.

Installation

Perform the procedures in the following sections to install the transducer on your boat.

1. Testing the Transducer Prior to Installation

Prior to installation, test the transducer to make sure that no damage occurred during shipping.

1. After connecting the transducer to the control head, hold the transducer in the water over the side of the boat

to confirm proper operation. If the transducer is working properly, you should be able to see the bottom on the

control head display. The bottom image should be relatively strong and there should be detailed structure on the

display.

2. Locating the Transducer Mounting Position

Outside the boat: The best location for the transducer will be aft midship, as close to the centerline of the boat as

possible. The transducer should be mounted forward of the propellers on inboard boats, and separated adequately

from other transducers, strakes, rivet lines, or other protrusions. Make sure that there is nothing in front, behind, or to

the side of the transducer that is closer than 12".

WARNING! Do NOT install the transducer in line with the engine intake.

Inside the boat: There must be room to access the mounting location for installation and cable routing.

Deadrise: Another consideration is the angle of deadrise.

• The transducer, when mounted, should point straight down. If the selected mounting location has a hull deadrise

of 2 degrees or greater, the included leveling block should be used to level the transducer housing and direct the

sonar signal straight down.

• If you need to use the leveling block, make sure that the inside surface of the hull is smooth enough to seat the

leveling block securely.

WEEE Directive: EU Directive 2002/96/EC “Waste of Electrical and Electronic

Equipment Directive (WEEE)” impacts most distributors, sellers, and manufacturers

of consumer electronics in the European Union. The WEEE Directive requires the

producer of consumer electronics to take responsibility for the management of

waste from their products to achieve environmentally responsible disposal during

the product life cycle.

WEEE compliance may not be required in your location for electrical &

electronic equipment (EEE), nor may it be required for EEE designed and

intended as fixed or temporary installation in transportation vehicles such as

automobiles, aircraft, and boats. In some European Union member states, these

vehicles are considered outside of the scope of the Directive, and EEE for those

applications can be considered excluded from the WEEE Directive requirement.

This symbol (WEEE wheelie bin) on product indicates the product must

not be disposed of with other household refuse. It must be disposed of

and collected for recycling and recovery of waste EEE. Johnson

Outdoors Marine Electronics, Inc. will mark all EEE products in

accordance with the WEEE Directive. It is our goal to comply in the collection,

treatment, recovery, and environmentally sound disposal of those products;

however, these requirements do vary within European Union member states.

For more information about where you should dispose of your waste equipment

for recycling and recovery and/or your European Union member state

requirements, please contact your dealer or distributor from which your product

was purchased.

Maintenance

If your boat remains in the water for long periods of time, algae and other

marine growth can reduce the effectiveness of the transducer. Periodically

clean the face of the transducer with hot water.

If your boat remains out of the water for a long period of time, it may take

some time to wet the transducer after it is returned to the water. Small air

bubbles can cling to the surface of the transducer and interfere with proper

operation. These bubbles will dissipate with time, or you may wipe the face of

the transducer with your fingers after the transducer is in the water.

Alternate Installation

(Deadrise greater than 2°)

Shows transducer close enough to center line so

that the hull will not interfere with side imaging Alternate Installation (Deadrise more than 2°): For an installation where the deadrise is more than 2 degrees, use

the included leveling block, cut at the appropriate angle, to compensate for the deadrise.

1. From the outside of the hull, drill a small pilot hole (smaller than the centering bit of your drill bit or hole saw),

at the mounting location you selected in section 2. Drill the hole perpendicular to the waterline.

2. Use the pilot hole (from the outside of the hull) to drill a 1 1/8" hole that is sized to fit the threaded stem of

the transducer. Drill the hole perpendicular to the waterline.

3. Thoroughly clean and deburr the drilled hole and clean the outside of the hull.

4. If the hull angle is greater than 2 degrees, cut the included leveling block and use both pieces to level the

transducer. The block should be cut to match the angle of the deadrise of the hull.

• Cut the leveling block into two equal pieces: one which mounts outside the hull and is shaped to

match the profile of the transducer, and one which mounts inside the hull and provides a level surface

for the fasteners.

• The thinnest wall of the outside leveling block must be at least 1".

• The leveling block included with your transducer can accommodate a maximum deadrise angle of 25

degrees.

5. The leveling block will be installed (cut) on the inside and outside of the hull. Proceed to Section 4: Attaching

the Transducer.

4. Attaching the Transducer

1. Feed the transducer cable through the drilled hole, then temporarily install the transducer to check the fit.

2. Apply a generous amount of marine-grade silicone sealant or slow-curing epoxy inside the drilled hole and along

the mating surfaces of the transducer housing and leveling block.

3. See the illustrations that correspond to your installation type and transducer orientation.

• Insert the transducer into the drilled hole from outside the boat with the leveling block(s) installed

according to your installation type, then install the nut onto the threaded stem from inside the boat.

Hand tighten the nut ON Y until the assembly is firmly seated, then tighten NO MORE than 1/8 of a

turn extra.

CAUTION: To avoid damage, do not overtighten the nut.

• Make sure that the narrow (thin) end of the transducer is pointing forward.

NOTE: This type of transducer is directional in nature and must be aligned with the front of the boat (the direction of

travel) and parallel to the center line. Failure to align the transducer properly will result in incorrect bottom readings

and incorrect fish locations. (See Illustration for orientation).

4. Remove the excess adhesive sealant from the outside of the hull to ensure smooth water flow over the

transducer.

Plastic Thru-Hull ide Imaging Transducer

531392-2_B

ide Imaging: The side imaging transducer has some special requirements because of its side viewing capabilities.

• The side imaging transducer must not have anything obstructing the ”view” of the side looking beams, i.e.

nothing can be in the line of sight of these beams (not a hull, motor, or other transducer, etc).

•In order for the side beams to be displayed accurately, the transducer must be mounted so that it is looking

straight down in the water when the boat is in the water.

NOTE: Rough seas can also affect the reading of the side imaging transducer.

Installation scenarios for consideration:

•Flat Hull, One Transducer: ocate a flat area on the bottom of the hull, forward of where the propeller shaft

comes out of the hull. Make sure there is nothing lower than this location to the right or left.

•V-shaped Hull, Two Transducers: Install two thru-hull side imaging transducers, one on each side of the V.

Connect the transducers with AS SI R Y cable.

•Two Back Engines, Two Transducers: Install two thru-hull side imaging transducers outboard from the dual

engines. Connect the transducers with AS SI R Y cable.

NOTE: AS SI LR Y and additional Side Imaging Thru-Hull Transducers must be purchased separately. Also, if the included

transducer will not work for your application, you may exchange it, NEW and UNASSEMBLED, with mounting hardware

included, for a transducer appropriate for your application - often at very little or no charge depending on the transducer.

See the FA (Frequently Asked uestions) section of our Web site at hu inbird.co or call our Customer Resource

Center at 1-800-633-1468.

3. Drilling the Hole and Installing the Leveling Block

Follow the instructions below for the installation type that matches your hull and deadrise.

tandard Installation (Flat Hull, Deadrise less than 2°): For an installation that needs to minimize the impact of a

small obstruction, but where the deadrise is less than 1 - 2 degrees, use the included leveling block (uncut), and

mount it outside the hull.

1. From the outside of the hull, drill a small pilot hole (smaller than the centering bit of your drill bit or hole saw), at

the mounting location you selected in section 2. Drill the hole perpendicular to the hull.

2. Use the pilot hole (from the outside of the hull) to drill a 1 1/8" hole that is sized to fit the threaded stem of

the transducer. Drill the hole perpendicular to the hull.

3. Thoroughly clean and deburr the drilled hole and clean the outside of the hull.

4. The leveling block will be installed (uncut) on the outside of the hull. Proceed to Section 4: Attaching the

Transducer.

CAUTION: Use only the leveling block included with this transducer. Do NOT use a wooden leveling block, as any

swelling of the wood might cause the plastic on the transducer to shatter.

NOTE: A separately-purchased leveling block can also be used to create a hydrodynamic waterflow around the

transducer body. The design and fabrication of this block varies greatly with different hull shapes; therefore, it should

be customized by a qualified marine technician.

NOTE: Replacement leveling blocks are available from Humminbird®. For assistance, contact the Humminbird®

Customer Resource Center at hu inbird.co or call 1-800-633-1468.

5. Routing the Cable

The transducer cable must be routed to the point where the control head is mounted.

NOTE: Your boat may have a pre-existing wiring channel or conduit that you can use for the transducer cable.

1. Unplug the other end of the transducer cable from the control head.

CAUTION! Do not cut or shorten the transducer cable, and try not to damage the cable insulation. Route the cable as far

as possible from any VHF radio antenna cables or tachometer cables to reduce the possibility of interference. If the cable is

too short, extension cables are available to extend the transducer cable up to a total of 50'. For assistance, contact the

Customer Resource Center at hu inbird.co or call 1-800-633-1468 for more information.

CAUTION! Do NOT mount the cables where the connectors could be submerged in water or flooded. If cables are installed

in a splash-prone area, it may be helpful to apply dielectric grease to the inside of the connectors to prevent corrosion.

Dielectric grease can be purchased separately from a general hardware or automotive store.

2. Route and secure the cable, avoiding areas where it may be damaged or interfere with normal boating

operations.

6. Connecting the Cable

Insert the transducer cable into the appropriate terminal slot. The cable connectors are labeled, and there are

corresponding labels on the cable holder on the rear of the control head. The slots are keyed to prevent reversed

installation, so be careful not to force the connector into the holder.

Your control head is now ready for operation.
