2. Using a Phillips screwdriver and a 7/16" wrench, loosely
tighten the pivot bolt. Do not completely tighten the
assembly at this time, so the pivot angle can be adjusted
later.
3. Only if you have a Kick-up transducer mounting assembly,
insert the pivot/transducer assembly into the mounting
bracket.
4. Do not snap the assembly closed.
4. Mounting the Transducer Assembly to the
Transom
1. Apply marine-grade silicone sealant to the mounting holes
drilled into the transom.
2. Align the transducer assembly with the drilled holes in the
transom.
3. 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 vertically adjust
the transducer. If you have a Two Piece Kick-up transducer
mounting assembly, snap the pivot down into place.

5. Running Position Adjustment

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.
4a. If you are using the Two Piece Kick-up mounting bracket,
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.
4b. If you are using the Single Piece mounting bracket, make sure that the transducer location
has not changed, then hand tighten the two mounting screws.
5. Confirm that the pivot angle has not changed.

6. Routing the Transducer Cable

There are several ways to route the transducer cable to the area
where the depthsounder will be installed. The most common
procedure routes the cable through the transom into the boat.
NOTE: Your boat may have a pre-existing wiring channel or conduit
that you can use for the transducer cable.
1. Unplug the other end of the transducer cable from the
depthsounder. Make sure that the cable is long enough to
accommodate the planned route by running the cable over
the transom.
CAUTION! Do not cut or shorten the transducer cable, and try not
to damage the cable insulation. Route the cable as far as possible from any VHF radio antenna
cables or tachometer cables to reduce the possibility of interference. If the cable is too short,
extension cables are available to extend the transducer cable up to a total of 50' (15 m).
For assistance, contact the Customer Resource Center at www.humminbird.com or call
1-800-633-1468 for more information.
NOTE: The Two Piece Kick-up transducers can pivot up to 90 degrees in the bracket. Allow
enough slack in the cable for this movement. It is best to route the cable to the side of the
transducer so the cable will not be damaged by the transducer during movement.
2a. If you are routing the cable over the transom of the boat, secure the cable by attaching the
cable clamp to the transom, drilling 9/64" dia. holes for #8 x 5/8" (16 mm) wood screw(s),
then skip directly to step 5.
2b. If you will be routing the cable through a hole in the transom, drill a 5/8" diameter (16 mm)
hole above the waterline. Route the cable through this hole, then fill the hole with marine-
grade silicone sealant and proceed to the next step immediately.
