Inside the Hull Transducer Installation
In-hull mounting generally produces good results in single-thickness
fiberglass-hulled boats. Humminbird® cannot guarantee depth performance
when transmitting and receiving through the hull of the boat, since some
signal loss occurs. The amount of loss depends on hull construction and
thickness, as well as the installation position and process.
NOTE:
In-hull mounting requires an installed and operational depth sounder.
1. Locating the Transducer Mounting Position
Decide where to install the transducer on the inside of the hull. Consider the
following to find the best location:
• Observe the outside of the boat hull to find the areas that are mostly free
from turbulent water. Avoid ribs, strakes and other protrusions, as these
create turbulence.
• As a general rule, the faster the boat can travel, the further aft and closer to
the centerline of the hull the transducer has to be located in order to remain
in contact with the water at high speeds.
WARNING!
This installation requires slow-cure two-part epoxy. Do not use
silicone or any other soft adhesive to install the transducer, as this material
reduces the sensitivity of the unit. Do not use five-minute epoxy, as it has a
tendency to cure before all the air bubbles can be purged, thus reducing signal
strength.
