Transom mount
For a vessel with an inboard engine, the transducer cannot be installed aft of the pro-
peller screw because of the turbulence created by the propeller ahead of the transduc-
er. Determine the mounting location considering the guidelines shown below and the
instructions on page AP-8.
• Select a location as far as possible from the propeller screw.
• Select a location where the propeller screw is not within 120° of the beam range of
the transducer.
Be sure to select the location considering these guidelines, to prevent echo noise on
the display.
