1157c Transducer Installation
(1157c Combo models only)
If you have a 1157c Combo model, there are three different installation methods for your transducer:
• Transom Transducer
• Inside the Hull Transducer
• Trolling Motor Transducer.
Your 1100 Series™ uses a Two Piece Kick-up transducer mounting bracket. Find the section that describes
the method of installation you will be using.
NOTE:
If the included transducer will not work for your application, you may exchange it, NEW and
UNASSEMBLED, with mounting hardware included, for a transducer appropriate for your application - often
at very little or no charge depending on the transducer. Call the Humminbird® Customer Resource Center at
1-800-633-1468
for details and pricing, or visit

.
NOTE:
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, a 12" plumb line (weighted string or
monofilament line), marker or pencil, safety glasses and dust mask, and marine-grade silicone sealant.
NOTE:
Due to the wide variety of hulls, only general instructions are presented in this installation guide. Each
boat hull represents a unique set of requirements that should be evaluated prior to installation. It is important to
read the instructions completely and understand the mounting guidelines before beginning installation.
NOTE:
When drilling holes in fiberglass hulls, it is best to start with a smaller bit and use progressively larger drill
bits to reduce the chance of chipping or flaking the outer coating.
NOTE:
Your transducer may not look exactly like the transducer shown in the illustrations, but it will mount in
exactly the same way.
