Installation Instructions

Sand both the inside surface of the hull,
where the transducer is to be epoxied,
and the face of the transducer.
You may want to start with a rougher
grit sandpaper, such as 60 grit, and n-
ish with a smoother grit, such as 160 grit,
sandpaper. Sand the inside surface of the
hull until it is smooth to the touch.
The sanded area should be about 1-1/2
times the diameter of the transducer. Af-
ter sanding, clean the hull and face of the
transducer with an alcohol wipe to re-
move any sandpaper grit and dust.
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. Make
sure there are no air pockets in the ep-
oxy layers.
Press the transducer into the epoxy, twist-
ing and turning it to force any air bubbles
out from under the transducer face. 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.
When nished, the face of the transducer
should be parallel with the hull with a
minimum amount of epoxy between the
hull and transducer.
After the epoxy has set, route the
transducer cable to the sonar unit.
