To mount the transducer pivot assembly to the bracket
(Single frequency units):
1. Insert the pivot/transducer assembly into the mounting bracket.
2. Do not snap the assembly closed.
3. Apply marine-grade silicone sealant to the mounting holes drilled into the
transom.
4. Align the transducer assembly with the drilled holes in the transom.
5. Using the appropriate tool for your mounting hardware,
attach the transducer assembly to the boat transom as
shown, using #8 x 5/8” (16 mm) wood screws. Do not fully
tighten the mounting screws in order to adjust the
transducer vertically. Snap the pivot down into place.
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 (Single frequency unit):
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 high-speed testing.
1. First, adjust the pivot angle of the transducer body, so its length is parallel with
the length of the hull of the boat. Then, using the angle portion of the mounting
template, pivot the transducer down so that it matches the template angle as
shown on the template itself.
2. Fully tighten the pivot bolt, using a Phillips head screwdriver and a wrench. It
may be necessary to re-tighten the pivot bolt after initial use as the plastic may
still be conforming to the pressure from the lock washers.
3. Before removing the template, adjust the height of the assembly so the face of
the transducer touches the face of the template. Mark the position of the
mounting bracket on the transom with a pencil.
4. Force the pivot to the Up position to gain access to the mounting screws. Make
sure that the transducer location has not changed, then hand tighten the two
mounting screws. Snap the pivot back down.
5. Confirm that the pivot angle has not changed.
NOTE: when you are done with this procedure, go to the section entitled: To route the
transducer cable.
