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.

Humminbird® Service Policy
Even though you'll probably never need to take advantage of our incredible
service policy, it's good to know that we back our products this confidently.
We do it because you deserve the best. We will make every effort to repair
your unit within three business days from the receipt of your unit at our
factory. This does not include shipping time to and from our factory. Units
received on Friday are typically shipped by the following Wednesday, units
received Monday are typically shipped by Thursday, etc.
All repair work is performed by factory-trained technicians to meet exacting
factory specifications. Factory-serviced units go through the same rigorous
testing and quality control inspections as new production units.
After the original warranty period, a standard flat rate service charge will be
assessed for each repair (physical damage and missing parts are not
included). Any repairs made after the original warranty will be warranted for
an additional 90 days after service has been performed by our factory
technicians. You can contact our Customer Resource Center or visit our web
site to verify the flat rate repair fee for your product (visit the Product Support
section):

We reserve the right to deem any product unserviceable when replacement
parts are no longer available or impossible to obtain. This Service Policy is
valid in the United States only. This applies only to Humminbird® products
returned to our factory in Eufaula, Alabama. This Service Policy is subject to
change without notice.

8. Hand tighten the nut ONLY 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.
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.humminbird.com
or call
1-800-633-1468
for more information.
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 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.

Attaching the Transducer
Before attaching your transducer, you will need to decide which type of installation to use:
• For a standard installation, where there are no major obstructions and the deadrise is less than 8 degrees, use
the included leveling block (uncut), and mount it inside the hull. Drill the hole perpendicular to the hull.
• For an installation that needs to minimize the impact of a small obstruction, but where the deadrise is less than
8 degrees, use the included leveling block (uncut), and mount it outside the hull. Drill the hole perpendicular to
the hull.
• For an installation where the deadrise is greater than 8 degrees, use the included leveling block, 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 1 1/8" hole that is sized to fit the threaded stem of
the transducer:
NOTE:
For installations where the deadrise is less than 8 degrees, where you will not be cutting the leveling block, drill the
hole perpendicular to the hull.
NOTE:
For installations where the deadrise is greater than 8 degrees, and you will be cutting the leveling block at an angle,
drill the hole perpendicular to the waterline.
3. Thoroughly clean and deburr the drilled hole and clean the outside of the hull.
4a. If the deadrise is less than 8 degrees, you will not be cutting the leveling block; install it either on the inside of
the hull (standard installation) or on the outside of the hull to compensate for small obstructions.
OR...
4b. If the hull angle is greater than 8 degrees, you should 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. The leveling block included
with your transducer can accommodate a maximum deadrise angle of 25 degrees.
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:
Replacement leveling blocks are available from Humminbird®. For assistance, contact the Humminbird® Customer
Resource Center at
www.humminbird.com
or call
1-800-633-1468
.
NOTE:
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 leveling 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. 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 as well.
7. Make sure that the narrow (thin) end of the transducer is pointing forward. Insert the transducer into the drilled
hole from outside the boat, then install the nut onto the threaded stem from inside the boat.
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).
