Operating Instructions and Installation Instructions

4. Most people can get good results by following steps 1 through 3, so this 
step is optional. If you want to make an extra effort to be absolutely 
sure that your selected location will work under all conditions, make a 
test run 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 24. 
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 bond-
ing. After sanding, clean the hull and transducer with rubbing alco-
hol to remove any sanding debris.
