3. If the bracket has been temporarily fas-
tened to the transom, remove it. Apply a
marine sealant to the threads of the three
#10 x 1-1/4" self tapping screws to pre-
vent water seeping into the transom.
Screw the bracket to the hull. Do not tight-
en the screws completely at this time.
4. Repeat step 1 to ensure that the angle of
the sensor is correct.
