HUMMINBIRD INSTALLATION GUIDE
There are three basic installation tasks that you must perform for the Humminbird Fishing System:
• Installing the Humminbird control head
• Installing the transducer
• Testing the complete installation and locking the transducer position.
The transducer can either be installed inside the hull, on the transom of the boat, or onto a trolling motor,
depending on your transducer type. There are also two different types of transducer mounting brackets, the Single
Piece and the Two Piece Kick-up. In addition, if you have purchased a Plus model, you may want to install the
included Temperature/Speed accessory, using the separate installation instructions included with the accessory.
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
(334-687-0503) for details and pricing, or visit www.humminbird.com, Product Support/Transducer Exchange for
more information.
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. In addition to the parts
supplied, you will need a hand drill with various bits, a socket (
marine-grade silicone sealant.
NOTE: Please read all instructions carefully and completely before beginning the installation process.
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.
