3. Put the pivot bolt through the assembly to
hold it in position and loosely install the nut,
but do NOT tighten the nut at this time (Figure
19).
CAUTION! Do not use a high speed driver on this
combination of fasteners. Hand tighten only.
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.
