• 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 (see the illustration Stepped Hull).
• 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.
NOTE: If you cannot find a transom mount location that will work for your high-
speed application, find an In-Hull Transducer by contacting our Customer
Resource Center at either 1-800-633-1468 or by visiting our Web site at
humminbird.com.
