5. Adjust
the transducer and bracket so that the front of the transducer
is slightly lower than the back. See the section on fish arches in this
manual for proper
transducer angles. Tighten all screws. (CAUTION:
Don't overtighten the bolt that holds the transducer to the bracket.
Overtightening the bolt
may
result in a distorted bracket which will allow
the transducer to "kick-up" at high speed.) Snap the transducer bracket
together by pressing the outer bracket (the one with the transducer
attached) against
the one screwed to the transom.
NOTE: Some aluminum boats with strakes or ribs on the outside of the
hull create large amounts of turbulence
at high speed. These boats
typically
have large outboard motors
capable
of propelling the boat at
speeds
over 35 mph. The
transducer should be mounted as far below
the hull as possible on these boats. (See below) This will place
the face
of the transducer below the turbulent
water, allowing the sonar unit to
work at high speeds.
6. Route the transducer cable to the sonar unit. Keep
the transducer
cable away from other wiring on the boat, if possible. Electrical noise
from
engine wiring or
bilge pumps can be picked
up on the transducer cable. This can show up
as
unwanted interference on the sonar
display.
7. Make a test run to determine the results. If
there is interference on the
display
when running
the boat at high speed, try lowering the
transducer's bracket as shown at right.

IMPORTANT!
Clamp the transducer cable to the transom close to the transducer.
This
will
prevent
the transducer from
entering the boat if it is knocked
off at high speed.
