5. Align the metal mounting bracket with the mounting holes. The center
slot should be above the two outer slots. (This bracket and all other
hardware supplied is top quality stainless steel for maximum strength
and corrosion protection.) Insert the three #10 - 1" long screws into the
drilled holes, but do not completely tighten.
To attach the pivot to the transducer:
1. Attach the pivot to the transducer body, using the two 1/4"-20 x 5/8"
(16 mm) machine screws, toothed washers, and square nuts. The
toothed washers must fit on the inside of the transducer ears,
between the pivot and the ears. The square nuts will be prevented
from rotating by the pocket in the back of the pivot. An Allen wrench
is provided which fits all the 1/4"-20 screws, but do not fully tighten
the screws at this time.
