Transom Mount Transducer Installation
Side Imaging ® Transducer, XHS 9 HDSI 180T (898c SI or 998c SI only)
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 marker or pencil, safety glasses and dust mask, and
marine-grade silicone sealant.
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 humminbird.com.
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: 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.
Transducer Mount Position
Unobstructed View: The jack plate gives
the transducer safe distance from the motor
and turbulence. The Side Imaging® has a
clear view side-to-side. Obstructed View: The transducer is too
close to motor turbulence, and the Side
Imaging® view is blocked by the motor. The
view cannot extend from side-to-side.
The Side Imaging® transducer has some special requirements
because of its side viewing capabilities:
• The Side Imaging® transducer must NOT have anything
obstructing the ‘view’ of the side looking beams, i.e.
nothing can be in the line of sight of these beams (not a
hull, motor, or other transducer, etc).
NOTE: You may need to tilt the motor up and out of the way when
using the side looking beams.
• In order for the side beams to be displayed accurately, the
transducer must be mounted so that it is looking straight
down in the water when the boat is in the water.
