WARNING! Do not touch an active transducer during operation, as this
may cause physical discomfort and may result in personal injury in the form
of tissue damage. Handle the transducer only when the power to the
fishfinder is off.
WARNING! This device should not be used as a navigational aid to
prevent collision, grounding, boat damage, or personal injury. When the
boat is moving, water depth may change too quickly to allow time for you
to react. Always operate the boat at very slow speeds if you suspect
shallow water or submerged objects.
WARNING! Disassembly and repair of this electronic unit should only be
performed by authorized service personnel. Any modification of the serial
number or attempt to repair the original equipment or accessories by
unauthorized individuals will void the warranty. Handling and/or opening
this unit may result in exposure to lead, in the form of solder.
WARNING! This product contains lead, a chemical known to the state of
California to cause cancer, birth defects and other reproductive harm.
The WEEE Directive aims to minimize the impact of end-of-life
electrical and electronic equipment on human health and the
environment. Therefore, any product bearing the WEEE symbol
must not be included with unsorted municipal waste. Instead, it
must be separately collected, treated and recycled.
For proper disposal of this equipment, please contact the Johnson Outdoors
distributor or see

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 hole saw to fit the threaded stem of the transducer, a large adjustable wrench, a level, and marinegrade 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 fishfinder, 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".

Bronze Thru-Hull Transducer
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 8 degrees or greater, a 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.
NOTE: 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. Call the Humminbird® Customer Resource Center at
1-800-633-1468 for details and pricing, or visit www.humminbird.com.
3. Attaching the Transducer
Before attaching your transducer, you will need to decide which type of installation to use:
• For a standard installation, where the deadrise is less than 8 degrees, you do not need to use a leveling
block because the transducer will be mounted directly to the hull; drill the hole perpendicular to the hull.
• For an installation where the deadrise is greater than 8 degrees, use a suitable leveling block (not
included), cut at the appropriate angle, to compensate for the deadrise. Drill the hole perpendicular to
the waterline.
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 procedure 2.
CAUTION: Before you drill, make sure you are drilling in the correct orientation according to the installation
guidelines above.
2. Use the pilot hole (from the outside of the hull) to drill a hole sized to fit the threaded stem of the
transducer:
NOTE: If you are mounting the transducer body directly to the hull, drill the hole perpendicular to the hull.
NOTE: If you are using a leveling block, drill the hole perpendicular to the waterline.
3. Thoroughly clean and deburr the drilled hole and clean the outside of the hull.
4a. If you are not using a leveling block, skip to step 5.
OR...
4b. If the hull angle is greater than 8 degrees, you should use a leveling block (not included) to level the
transducer. The block (usually made of wood) should be cut to match the angle of the deadrise of the hull.
You should 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 level block must be at least 1/8".
NOTE: A separately-purchased fairing block can also be used to create a hydrodynamic waterflow around the
transducer body. A fairing block is required for round body transducers as well. The design and fabrication of this
block varies greatly with different hull shapes; therefore, it should be customized by a qualified marine technician.
5. Feed the cable through the hole, then temporarily install the transducer to check the fit.

6. 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. Seal the mating edges of the leveling block
(if using one) as well.
7. Insert the transducer into the drilled hole from outside the boat, then install the nut onto the threaded
stem from inside the boat.
NOTE: If you are using a leveling block outside the hull (to correct for deadrise), you must use a similar block
inside the hull to provide a level bearing surface.
8. Tighten the nuts to 10 ft/lbs or use moderate pressure on an adjustable wrench.
CAUTION: Do not overtighten the nuts, especially if you are using a leveling block made of wood, as the block
will swell when wet.
Remove the excess adhesive sealant from the outside of the hull to ensure smooth water flow over the
transducer.
4. 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 www.
for more information.
humminbird.com or call 1-800-633-1468
2. Route and secure the cable, avoiding areas where it may be damaged or interfere with normal boating
operations.
5. 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 fishfinder. The slots are keyed to prevent
reversed installation, so be careful not to force the connector into the holder.
Your fishfinder is now ready for operation.

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.
