mounting hole. Be sure the triangular recess in the fairing is point-

fairing as your guide, drill a hole through the hull for the anti-rota-
tion bolt.
6. Remove the assembly and cable from the mounting hole.
7. Sand and clean the area around the hole, inside and outside, to
ensure that the sealant will adhere properly to the hull.

1. Remove the transducer from the fairing, if used.
2. Stainless steel transducer in metal hull - Slide the appropriate
size isolation sleeve over the cable and onto the stem of the trans-
ducer as far down as possible (see Figure 2-3 ). Be sure the top of
the isolation sleeve will be below the top of the backing block to
prevent the sleeving from interfering with tightening the hull nut.
WARNING:
To prevent electrolytic corrosion, never allow direct contact
between a stainless steel transducer and a metal hull.
