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.
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.
6. When finished, the face of the transducer should be parallel
with the hull with a minimum amount of epoxy between the
hull and transducer.
