Transom Mounted Transducer
Areas of Possible Turbulence
Supplies: In addition to the hardware supplied with your transducer, you will need a powered hand drill and
various drill bits, various hand tools, including a ruler or measuring tape, level, pen or pencil, safety glasses
and dust mask, and marine-grade silicone sealant.
Installation
There are a number of ways to install a transducer on your boat. The transom mount installation provides
the least loss of signal since the transducer is mounted outside the boat hull. This installation also allows
adjustment of both running angle and depth after the transducer is mounted, which enables you to tune the
installation for best results. Also, the mounting hardware is designed to pivot the transducer body out of the
way should the boat strike debris in the water, or when trailering.
1.Locating the Transducer Mounting Position
Turbulence: You must first determine the best location on the transom to install the transducer. It is very
important to locate the transducer in an area which is relatively free of turbulent water. Consider the
following to find the best location with the least amount of turbulence:
• As the boat moves through the water, turbulence is generated by the weight of the boat and the thrust
of the propeller(s) - either clockwise or counter-clockwise. This turbulent water is normally confined to
areas immediately aft of ribs, strakes or rows of rivets on the bottom of the boat, and in the immed iate
area of the propeller(s). Clockwise propellers create more turbulence on the port side. On outboard or
inboard/outboard boats, it is best to locate the transducer at least 15" to the side of the propeller(s).

strakes hull
Stepped Hull
• The best way to locate turbulence-free water is to view the transom while the boat is moving. This
method is recommended if maximum high-speed operation is a high priority. If this is not possible,
select a location on the transom where the hull forward of this location is smooth, flat and free of
protrusions or ribs.

• On boats with stepped hulls, it may be possible to mount the trans ducer on the step. Do not mount the
transducer on the transom behind a step to avoid popping the transducer out of the water at higher
speeds. The transducer must remain in the water for the control head to maintain the sonar signal.
• If the transom is behind the propeller(s), it may be impossible to find an area clear from turbulence, and a
different mounting technique or transducer type should be considered. See the FAQ (Frequently Asked
Questions) section of our Web site at humminbird.com or call Customer Service at 1-800-633-1468.
• If you plan to trailer your boat, do not mount the transducer too close to trailer bunks or rollers to avoid
moving or damaging the transducer during loading and unloading of the boat.
Find a turbulence-free location at least 15" from the propeller(s) and not in line with trailer bunks or rollers.

Transducer Mount Position
Unobstructed View: The jack plate gives the transducer
safe distance from the motor and turbulence. The Side
Imaging has a clear view side-to-side.
NOTE: The hydrodynamic shape of your transducer allows it to point straight down without deadrise adjustment.
NOTE: If you cannot find a transom mount location that will work for your high-speed application, a different
mounting technique or transducer type should be considered. See the FAQ (Frequently Asked Questions) section of
our Web site at humminbird.com or call Customer Service at 1-800-633-1468.
Side 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; for example, nothing can be in the line of sight of these beams (not a hull, motor, or other
transducer, etc.)
NOTE: You may need to tilt the motor up and out of the way when using the side looking beams.
• In order for the side beams to be displayed accurately, the transducer must be mounted parallel
with the waterline. This positioning allows the beam elements to point straight down without
deadrise adjustment (see the illustration Deadrise).
2.Mounting the Bracket
In this procedure you will mount the bracket, using the mounting template provided as a guide. This
template allows you to mark where the mounting holes should be drilled.
Obstructed View: The transducer is too close to motor
turbulence, and the Side Imaging view is blocked by the
motor. The view cannot extend from side-to-side.
Attaching the Bracket
1. Cut out the transducer mounting template from this sheet. Match the mounting bracket screw slots to
the template screw slots.
2. Hold the template on the transom of the boat in the location you have selected. Align the template
vertically, matching the lower edge of the transom with the bottom corner of the template.
NOTE: If your propeller moves clockwise as the boat moves forward (as you're facing the stern of the boat
from behind), mount the transducer on the starboard side, and use the bottom left corner of the template. If
your propeller moves counter-clockwise as the boat moves forward (as you're facing the stern of the boat from
behind), mount the transducer on the port side, and use the bottom right corner of the template.

3. Continue to hold the template on the transom of the boat, and use a pencil or punch to mark where to
drill the three mounting holes shown on the template.
4. Using a 5/32" bit, drill the three holes only to a depth of approximately 1".
NOTE: On fiberglass hulls, it is best to use progressively larger drill bits to reduce the chance of chipping or
flaking the outer coating.
5. Use a marine-grade silicone sealant to fill the drilled holes, especially if the holes penetrated the
transom wall.
6. Align the metal mounting bracket with the mounting holes. The center slot of your mounting bracket
should be above the two outer slots. This bracket and all other hardware supplied is top quality stainless
steel for maximum strength and corrosion protection. Insert the three 1" flat head wood screws into the
drilled holes, but do not completely tighten.
3.Assembling the Transducer
In this procedure you will attach the pivot to the transducer using the hardware provided.
1. Attach the pivot to the transducer body as shown in the illustration using the square nuts, toothed
washers, and two 1/4–20 x 5/8" machine screws. The square nuts will be prevented from rotating by the
pocket in the back of the pivot. The toothed washers must fit on the inside of the transducer ears,
between the pivot and the ears.
NOTE: An Allen wrench is provided which fits all of the 1/4–20 screws, but do not fully tighten the screws at
this time.

4.Attaching the Transducer to the Bracket
1. Slide the assembled transducer into the metal bracket from the bottom, aligning the large hole at the
top of the bracket with the hole in the pivot.
2. Insert the headed pin through the pivot holes in the bracket and pivot. The headed pin can be inserted
from either side of the bracket.
3. Place the nylon washer over the opposite end of the headed pin. Place the stainless washer over the
1/4–20 x 5/8" screw threads, then insert into the opposite end of the headed pin and finger tighten only.
The screw has a thread locking compound on the threads to prevent loosening, and should NOT be fully
tightened until all adjustments are made.
5.Running Position Adjustment
The running position of the transducer is now completely adjustable. Subsequent adjustment may be
necessary to tweak the installation after high speed testing. The mounting bracket allows height and tilt
adjustment; the pivot screws allow angle adjustment.
NOTE: Side Imaging is best performed at boat speeds from 2 to 6 mph. If the boat is stationary, the same
information is displayed over and over. If the boat is moving too quickly, there will be gaps between the strips
of information. The best boat speed to use will depend on the side range selected. Slower speeds are good for
longer ranges, while faster speeds can be used at shorter ranges.
