4. 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.
CAUTION! Do not use a high speed driver on this combination of fasteners. Hand-tighten
only.
5. Insert the pivot arm assembly into the mounting bracket as shown in the illustration.
Do NOT snap the assembly closed, as you will need to access the mounting bracket in the next
step.
NOTE: If the pivot assembly is snapped closed over the mounting bracket, use a flathead
screwdriver or similar tool to gently pry the assembly away from the mounting bracket.
Mount the Transducer
6. 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). 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.
7. Snap the pivot arm down into place.
Make Adjustments to the Transducer Mounting Position
8. 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. See the illustration Adjusting the Initial Transducer
Angle.
