Following are instructions for transom mount installation. The transom mount installation provides the least loss of signal since the transducer is mounted outside the hull. This installation also allows adjustment of both running angle and depth after the transducer is mounted, which enables you to tune the installation for best results.
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 chippingor flaking the outer coating.
NOTE: If you cannot find a transom mount location that will work for your boat hull, a different mounting technique or transducer type should be considered. See the FAQ (Frequently Asked Questions) section of our Web site at humminbird.com or call our Customer Resource Center at
