element to be mounted below the bottom of the boat hull keeping the transducer out
of turbulent water and insuring good high speed operation. The transducer will
absorb the blow of any obstruction by rotating up out of the metal spring bracket
without harming the transducer, or your boat. The transducer can be re-engaged by
simply rotating the transducer down and snapping it back in place. (See Figure A)

B. Inside Hull Mount- The high speed transducer can be mounted inside the hull
(without pivot assembly) using the proper two-part epoxy, such as Humminbird’s
epoxy kit. Even though there is some loss of signal in shooting through the hull, your
LCR will perform well with this type of installation. You cannot shoot through the hull
of an aluminum boat.

C. Trolling motor Mount- This type of transducer is not supplied with your LCR. It is
designed to mount on the foot of a trolling motor. You may exchange your un-used
high speed transducer for a trolling motor transducer. Call the Humminbird
Customer Service Department.

D. Bronz Thru-Hull Mount- This transducer is not supplied with your LCR but for an
additional cost you may exchange your un-used high speed transducer for a bronz
thru-hull. The bronz thru-hull transducer has a threaded stem which installs through
a hole drilled in the boat hull, leaving the housing exposed under the boat. This type
of installation must be used for many boats with in-board engines, because there is
no suitable location on the transom away from the noise and turbulence created by
the prop. A bronz thru-hull transducer should be installed by qualified personnel
only.
The LCR will operate well at high speeds with a properly mounted transducer.
Remember, a transducer will not work transmitting through air or through air
bubbles.

1. TRANSOM MOUNTING PROCEDURE
Step 1.
MOUNTING LOCATION- It is important that the transducer be mounted on the transom
where water flow is in constant contact with the transducer. You may wish to observe
the rear of the boat while it is moving through the water to determine the best mounting
location.
