3. Re-position the transducer assembly against the transom of the
boat, then hand install the first three screws (two on the outside
edges and one in the 3rd mounting hole). Make sure that the
transducer location and the pivot angle have not changed, then
fully tighten all three mounting screws. Hand-tighten only!
4.
Snap the pivot back down. Install #8 x 1" wood screw into the 4th
hole to lock down the pivot arm.
Hand-tighten only!
Inside the Hull Transducer Installation
(1157c Combo models only)
If you choose to mount your transducer inside the hull of your boat, perform the procedures in this section.
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.
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.
NOTE: In-hull mounting requires an installed and operational control head.
NOTE: Do NOT install the 1197c Side Imaging transducer inside the hull, as the side
looking beams CANNOT penetrate the hull. Only the 1157c Dual Beam PLUS™ transducer
can be mounted inside the hull.
