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.

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 immediate 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" (380 mm) to the side of the propeller(s).
• 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 transducer 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, such as an Inside the Hull Transducer.
