To mount the transducer pivot assembly to the bracket (Dual frequency units):
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
NOTE: The running position of the transducer is now completely adjustable. Subsequent adjustment may be necessary to tweak the installation after high speed testing.

To adjust the running position of the transducer (Dual frequency units):
The transducer mounting bracket allows height and tilt adjustment, while the pivot bolt allows angular adjustment. These adjustments will help reduce cavitation. Initially, adjust the transducer as described in the following paragraphs. Further adjustment may be necessary to refine the installation after

1.First, adjust the pivot angle of the transducer body, so it is parallel with the length of the hull of the boat.
2.Fully tighten the two pivot screws, using the supplied Allen wrench. Access to the pivot screws is provided by the lower holes in the side of the mounting bracket. It may be necessary to
3.Adjust the height of the assembly so the face of the transducer is 1/8" (3 mm) to 1/4" (6 mm) beneath the bottom of the transom, and fully tighten the three mounting screws.
4.In order to gain access to the mounting screws, the
transducer assembly must be pivoted up in the bracket as Tighten the Mounting Screws shown. Be careful not to alter the running angle as some
force is necessary to pivot the assembly.
