with the boat on plane and observe the bottom signal. You'll need to figure
some way to prop the transducer into position while you make your test
run. (A brick or two might be sufficient to hold it in place.)
5. When you're satisfied with a location, mark it and proceed with the
installation.
Shoot-Thru-Hull Installation
If you are installing the transducer on a hull with floatation material
sandwiched within the hull, refer to the text "Hulls With Flotation Ma-
terials" beginning on page 26.
1. Make sure the area is clean, dry and free of oil or grease, then sand
both the inside surface of the hull and the face of the transducer with
100 grit sandpaper. The sanded hull area should be about 1-1/2 times
the diameter of the transducer. The surface of the hull must be flat so
the entire transducer face is in contact with the hull prior to bonding.
After sanding, clean the hull and transducer with rubbing alcohol to
remove any sanding debris.
Epoxy transducer to hull.
WARNING:
Use only the epoxy available from LEI. It has been for-
mulated to work with these installation procedures.
Other epoxy types may be too thin or may not cure to the
right consistency for optimum transducer performance.
2. The epoxy consists of the epoxy itself and a hardener. Remove the
two compounds from the package and place them on the paper plate.
