Humminbird 917C Inside the Hull Transducer Installation, Locate transducer mounting location

8.Re-position the transducer assembly against the transom of the boat, then hand-install all three screws. Make sure that the transducer location and the pivot angle have not changed, then fully tighten all three mounting screws. Snap the pivot back down. If you have performed the preceding procedures correctly, the transducer should be level and at the right height for optimal operation.

Fully Tighten All Three	Inside the Hull Transducer Installation
Mounting Screws	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: The integral temperature probe will not work with in-hull mounting, so you
	may either want to consider purchasing a Temperature/Speed accessory, a Temp
	Sensor, or obtaining a different transducer. Humminbird® offers a transducer
	exchange program to swap the NEW and UNASSEMBLED transducer, accompanied
	by mounting hardware, for one without an integral temperature probe. Call the
	Humminbird® Customer Resource Center at 1-800-633-1468 for details, or visit
	www.humminbird.com for more information.
	NOTE: Your transducer may not look exactly like the transducer shown in the
	illustrations, but it will mount in exactly the same way.
