Side Imaging Requirements
In addition to the requirements shown in the Transom Transducer
Mounting Requirements section, 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, additional transducer, etc.). See the
illustrations below.
NOTE: You may need to tilt the motor up and out of
the way when using the side looking beams.
Transducer Mount Position: Unobstructed View
The jack plate gives the transducer safe distance from the motor
and turbulence. The Side Imaging beams have a clear view side-to-side.
Transducer Mount Position: 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.

Use the procedures in this section to install the Side Imaging transducer on your boat. The
transducer mounting template is provided at the end of this manual (see Side Imaging
Transducer Mounting Template).
NOTE: See the Transom Transducer Mounting Requirements before beginning the
installation.

Multiple Transducer Installation (optional)
If you have installed or are planning to install a second transducer
in addition to this Side Imaging transducer, you must determine
which transducer will be used as the primary source for traditional
2D sonar when operating the boat at high speeds (up to 65 mph).
There are special mounting requirements for the Side Imaging
transducer depending on if it will be in the water or out of the water
during high-speed operation.
Primary Source - Side Imaging Transducer
If you plan to use the Side Imaging transducer as the primary
source for traditional 2D sonar and Down Imaging sonar during
high-speed operation (up to 65 mph), mount the transducer at
least 15" from the center of the engine with an unobstructed view
on both sides of the transducer (see Side Imaging Requirements
and the illustration Transducer Mount Position: Unobstructed
View).
Primary Source - Secondary Transducer
If you plan to use a second transducer as the primary source for
traditional 2D sonar only during high-speed operation (up to 65
mph), mount the Side Imaging transducer where it will not be in
direct water flow. For this installation, you may install the
transducer less than 15" from the center of the engine. Review
the following mounting alternatives:
• The Side Imaging transducer can be mounted on or near the
centerline of the boat and higher on the transom to prevent
direct contact with water flow under the boat at high speeds.
Confirm that the transducer is low enough on the transom to
be submerged in the water at low speeds. It should not come
into contact with the motor when it is raised or lowered.
NOTE: Mounting the Side Imaging transducer higher
on the transom should not create turbulence that
affects the engine's water intakes. Contact your
dealer to verify your individual boat setup.
• The Side Imaging transducer can be mounted to the jack
plate. Contact your dealer for more information about the
brands of jack plates that will accommodate this type of
installation.
NOTE: A Y-cable or transducer switch may be required
to connect the Side Imaging transducer to the second
transducer. The Y-cable and transducer switch require
separate purchases.
