hold it in position and loosely install the nut,
but do NOT tighten the nut at this time
(Figure 19).
4. Align the mounting bracket transducer
assembly with the drilled holes in the
transom. With a 5/16" socket driver, mount
the assembly to the transom using the two
#10 - 1" long screws provided (Figure 20).
Hand tighten only!
NOTE: Make sure that the mounting screws are
snug, but do not fully tighten the mounting screws at
this time to allow the transducer assembly to slide for
adjustment purposes.
5. Adjust the initial angle of the transducer from
back to front by rotating the transducer until
the side seam on the transducer is almost
parallel with the bottom of the boat, one click
at a time in either direction (Figure 21 and 22).
