1. Apply silicone sealant to the mounting holes drilled into the transom.
2. Align the transducer assembly with the drilled holes in the transom (Figure 8).
3. Use either a flat head screwdriver, a
socket to mount the assembly. Using the two #10 - 1" (25mm) long slotted hex
head screws, mount the transducer assembly to the transom as shown. Do not
fully tighten the mounting screws in order to vertically adjust the transducer. Snap
the pivot down into place.
Note: A third mounting screw location is provided in the mounting bracket.
Drill and install this ONLY after final testing and adjustments have been
made.

Correct transducer height and running angle settings are needed to ensure best performance
at all boat speeds. Use the template provided to make the initial setting for most boats.
Some boat hulls require adjustments beyond these settings for best performance at all
speeds.
1. Cut out the transducer templates from page 5 of this pdf file. Follow the
directions for your hull type, i.e. fiberglass or aluminum.
2. Adjust the height on the transom and the pivot bolt angle to match guides on
the template as shown.
3. Hand tighten the Pivot Bolt and Mount Screws at this time. Ensure the height
and angle have not changed.

The cable must be routed to where the control head will be mounted. Consider the following:
• The easiest method to get the cable into the boat routes the cable over the transom. The
most common method drills a hole through the transom, above the water line.
" (8mm)
• Once inside the boat, the cable routes through or along internal conduits and channels.
• Keep the cable as far away as possible from VHF radio
antenna and tachometer cables.
• Do not cut, shorten or lengthen the transducer cable.
• If the cable is too short, extensions are available at your
dealer or direct from Humminbird.

OLLOW THESE STEPS
1. Run the cable over the transom or through a "
(16mm) hole drilled well above the water line.
2. If a hole was drilled, fill it with silicone sealant.
3. Secure the cable with clamps as shown. (Figure 6).
1. Insert the Mount Arms through the Base.
2. Secure the Mount Arms with the 4 screws provided.

1. Insert the Pivot Bolt through the Pivot Knuckle on the control head.
2. Thread the Gimbal Knob onto the Pivot Bolt using only 2-3 turns.
3. Align the Pivot Knuckle with the Mount Base Arms and slide into place until it seats firmly. A
slight twist will aid in seating the unit.
4. Rotate the Control Head to the desired angle and hand tighten the Gimbal Knob.
Now you can use the assembled Piranha to identify the best mounting location.
