Drill the Mounting Bracket Mounting Holes
1. Set the control head mounting bracket in place on the mounting surface. Mark the four mounting
screw locations with a pencil or punch.
2. Set the mounting bracket aside, and drill the four mounting screw holes using a
4.
Route the Cables Through the Mounting Bracket
1a. If the cables must pass through a hole directly beneath the mounting bracket, mark and drill an
additional 1" (25 mm) hole centered between the four mounting holes (Figure 5). Route the cables
through the grommet, then press the grommet in place around the cables and into the 1"(25 mm) hole.
Pass the cables out of the top of the mounting bracket (Figure 6).
1b. If the cables cannot be routed directly beneath the mounting bracket, mark and drill a 1" (25 mm)
hole that will allow you to run the cables close to the bracket. Pass the cables through the 1" (25
mm) hole, through the mounting base, and out of the top of the mounting bracket (Figure 7).
Using needle-nose pliers, break out the tabs on the rear of the mounting base (Figure 8). Place the
Hole Cover over the mounting surface hole, then use it to mark the position of the two mounting
screws. Remove the Hole Cover, drill the two mounting holes using a
with marine-grade silicone, then replace the Hole Cover and insert the #8 Phillips countersink
wood screws. Hand-tighten only.
2. Place the mounting bracket on the mounting surface aligned with the drilled holes and fill the
mounting holes with marine grade silicone. Insert the four #8 Phillips countersink wood screws
into the mounting holes. Hand-tighten only.

Assembling the Connector Holder
1. Insert both the power and the transducer cable plugs into the connector holder. The cable plugs
are labeled, and there are corresponding labels on the connector holder (Figure 9). The slots for the
plugs are keyed to prevent reverse installation, and insertion should be easy - do not force plugs.
2. Carefully pull the excess cable from beneath the mounting surface so that the connector holder
aligns with the mounting holes on the front of the mounting bracket (Figure 10).
3. Snap the support plate onto the rear of the connector holder (Figure 11).
4. Insert the connector holder into place and fasten it to the mounting bracket using the two
#6-32 x " (19 mm) screws (Figure 12). Hand-tighten only.
5. Slide the control head onto the mounting bracket until it is fully seated. To remove the unit, grasp
the unit with both hands, then firmly press the latch on the rear of the unit and lift (Figure 13).
NOTE: This latch is heavy-duty to withstand marine use, and significant force must be applied.
You are now ready to install the transducer. Find the section that refers to your transducer type.
