Side Imaging® Transducer
2. Hold the template on the transom of the boat in the location you have selected. Align the template
vertically, matching the lower edge of the transom with the bottom corner of the template.
NOTE: If your propeller moves clockwise as the boat moves forward (as you're facing the stern of the boat from
behind), mount the transducer on the starboard side, and use the bottom left corner of the template. If your
propeller moves counter-clockwise as the boat moves forward (as you're facing the stern of the boat from
behind), mount the transducer on the port side, and use the bottom right corner of the template.
3. Continue to hold the template on the transom of the boat, and use a pencil or punch to mark where to
drill the three mounting holes shown on the template.
4. Using a 5/32" bit, drill the three holes only to a depth of approximately 1".
NOTE: On fiberglass hulls, it is best to use progressively larger drill bits to reduce the chance of chipping or
flaking the outer coating.
5. Use a marine-grade silicone sealant to fill the drilled holes, especially if the holes penetrated the
transom wall.
6. Align the metal mounting bracket with the mounting holes. The center slot of your mounting bracket
should be above the two outer slots. Insert the three 1" flat head wood screws into the drilled holes, but
do not completely tighten.
NOTE: The mounting bracket and all other hardware supplied is top quality stainless steel for maximum strength
and corrosion protection.

Assemble the Transducer
In this procedure you will attach the pivot to the transducer using the hardware provided.
1. Attach the pivot to the transducer body as shown in the illustrations using the square nuts, toothed
washers, and two 1/4–20 x 5/8" machine screws. The square nuts will be prevented from rotating by the
pocket in the back of the pivot. The toothed washers must fit on the inside of the transducer ears,
between the pivot and the ears.
NOTE: An Allen wrench is provided which fits all of the 1/4–20 screws, but do not fully tighten the screws at this time.
5.
Attach the Transducer to the Bracket
1. Slide the assembled transducer into the metal bracket from the bottom, aligning the large hole at the
top of the bracket with the hole in the pivot.
2. Insert the headed pin through the pivot holes in the bracket and pivot. The headed pin can be inserted
from either side of the bracket.
3. Place the nylon washer over the opposite end of the headed pin. Place the stainless washer over the
1/4–20 x 5/8" screw threads, then insert into the opposite end of the headed pin and finger tighten only.
The screw has a thread locking compound on the threads to prevent loosening, and should NOT be fully
tightened until all adjustments are made.
6.
Running Position Adjustment
The running position of the transducer is now completely adjustable. Subsequent adjustment may be
necessary to tweak the installation after high speed testing. The mounting bracket allows height and tilt
adjustment; the machine screws allow angle adjustment.
