transducer out of the water at higher speeds. The transducer must
remain in the water for the control head to maintain the sonar signal
(Figure 10).
• 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.
• 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.
• If high speed operation is critical, you may want to consider using an
In-Hull transducer instead of this Transom Mount transducer.
NOTE: The hydrodynamic shape of your transducer allows it to point straight down
without deadrise adjustment (Figure 12).
2. Prepare the Mounting Location
After determining the mounting location for the transducer, follow the steps
below to position and mount the transducer bracket.
NOTE: If you cannot find a transom mount location that will work for your
high-speed application,please visitthe FAQ (FrequentlyAsked Questions)section
