6. Use a good quality two-part
epoxy
to bond the transducer
to the hull. Do not use
silicone rubber sealer or any
adhesive that does not get
rock hard. Follow the instruc-
tions on the epoxy package
and mix it thoroughly.. Apply
a small amount on the entire
face of the transducer and
pour 1/16" thick level into the
area contained by the clay
dam. Place the transducer
into the epoxy
by pushing and
turning to force all of the air
bubbles out from under the
transducer face. The trans-
ducer face should be parallel
with the boat hull, with a
minimum amount of
epoxy
between hull and transducer.
Weight the transducer down
until the epoxy
cures.
7. Route the transducer cable
along gunwales and away
from power
cables.
TRANSOM MOUNT
1. Loosely
attach the brackets to
the transducer with the
hardware provided.
2. Locate the bracket where the
flow of water is smoothest
with minimum turbulence
and bubbles.
Also, the bracket
or transducer should not in-
terfere with the boat trailer
or hauling
of the boat.
3. 1'ypically, the transducer
should be located half-way
be-
tween the center of the
transom and the outside edge
of the hull. (See Figure 8.)
The transducer should be
mounted away from stakes,
ribs, or other hull fittings
that can cause turbulence.
4. If
the hull deadrise exceeds 4
degrees, a shoot-thru-hull
mount on the centerline of
-
the hull or an optiQnal trans-
ducer should be used. (See
Figure 9.)
5. Place the bracket against
the
transom in the selected area
with the bottom of the trans-
ducer flush with the bottom of
the hull. Alignthe transducer
with the bottom of the boat
hull by using
a straight edge.
Mark
the transom for drilling
Your EAGLE trans-
lates time into dis-
tance — the farther
the sound waves go,
the longer it takes
them to return to the
transducer and the
greater the depth
shown on the dial.
Nowhere is this shown
more clearly than
when your boat passes
over a steep, rocky
underwater ledge or
cliff; either vertical or
inclined at a steep angle.
Assume the top of
the cliff is 15 feet be-
neath the surface of
the water, and the bot-
tom is 50 feet deep.
Sound waves will hit
rough spots on the cliff
all the way down. As
the result,
the signals
on the dial will cover

an area

extending
from 15 to 50 feet — a
condition that could
easily
lead to confu-
sion until you under-
stand it.
