Humminbird APEX Series Installation Manual

TRANSOM TRANSDUCER Installation Guide
The transom mount installation allows adjustment of both running angle and depth after the
transducer is mounted, which enables you to tune the installation for best results. It is important
to read the instructions completely and understand the mounting guidelines before beginning this
installation.
NOTE: Due to the wide variety of hulls, only general instructions are presented in this guide. Each
boat hull represents a unique set of requirements that should be evaluated prior to installation.
For detailed information about installing transducers on different hull types, download the
Transducer Installation Resource Guide from our Web site at humminbird.com.
NOTE: Your transducer may not look exactly like the transducer shown in the illustrations, but it
will mount in exactly the same way.
Install the control head before you start the transducer installation. See the control head
installation guide.
Review your boat manufacturer's owner's manual for recommended transducer installation
locations and cable routing methods, as well as your transom and/or deadrise angle.
Read and understand your boat's warranty before starting this installation.
Visit our Web site at humminbird.com for additional information and resources for transducer
installations. Also, visit youtube.com/humminbirdtv for informational videos.
Confirm your boat is level for the installation.
Consider your speed requirements.
Traveling over 65 mph with the transducer in the water is not recommended with the
transom mount transducer, as damage may occur. If speed above 65 mph is critical, see the
FAQ (Frequently Asked Questions) section of our Web site at humminbird.com.
Supplies: In addition to the hardware supplied with your transducer, you will need a powered
hand drill and various drill bits, various hand tools, including a ruler or straightedge, a level,
marker or pencil, Phillips-head screwdriver, flat head screw driver, a socket/nut driver, a 1/2"
(13 mm) wrench and torque wrench, safety glasses and dust mask, marine-grade silicone
sealant, and dielectric grease (optional). You may also need extension cables and hardware for
routing the cable to the control head.
Installation Overview
New Installation: Review Turbulence-Free Mounting Guidelines and proceed to section 1. Mount
the Transom Bracket to the Boat.
Previously-installed Transducer: If you have a previously-installed XHS transducer on the transom,
the bracket in this installation kit can be installed in the same location using the following
instructions:
1. Line up the metal bracket with the previously-used mounting holes to confirm that the two slot
holes match the previous installation. Fill any unused holes with marine-grade silicone sealant.
