Traditional Sonar
transducer face is in contact with the hull. Also, make
sure the cable is long enough to reach the sonar unit.
To use shoot-thru-hull installation:
1. Sand the inside surface of the hull, where
the transducer is to be epoxied, and the
face of the transducer. Sand the hull until
it is smooth to the touch. The sanded
area should be about 1-1/2 times the
diameter of the transducer.
2.
After sanding, clean the hull and the face
of the transducer with an alcohol wipe to
remove any dust.
3. Apply a thin layer of epoxy (about 1-16”
or 1.5 mm) on the face of the transducer
and the sanded area on the hull.
Be
careful when mounting a transducer
inside a boat hull. Once epoxied into
position, the transducer can be very
difficult to remove. Epoxy is available
at www.lei-extras.com (Part No. 106-
98).
4.
Press the transducer into the epoxy,
turning it to force out any air bubbles from
under the transducer face.
Make sure
there are no
air pockets
in the epoxy
layers.
5. Stop pressing
when it bottoms
out on the hull.
Apply pressure to hold the transducer in
place while the epoxy sets. Be careful not
to move the transducer while the epoxy
is setting. Allow the epoxy to set before
moving the boat.
