Determine the Mounting Location
Pre-assemble the control head to plan the best mounting location.
1. Place one urethane washer on one of the gimbal knobs. Thread the gimbal knob and
washer into the control head housing and tighten using 2-3 rotations. This will allow the
knob to stay in place while leaving adequate space to install the control head into the
bracket in the proceeding steps. See the illustration Assembling the Control Head.
2. Repeat step 1 for the other side of the control head.

3. Install the control head into the arms of the bracket mount. Confirm the front of the
gimbal bracket is aligned with the front of the control head (see the illustration Gimbal
Bracket).
4. Hand-tighten the gimbal knobs to secure the control head to the gimbal bracket.
5. Place the assembled control head in various locations to determine the best mounting
location.
Consider the following when choosing a mounting location:
• The mounting area should allow sufficient room (approximately 2 to 4 inches [50.8
to 101.6 mm]) behind the chosen location to drill up to four 1-inch (25.4 mm) holes
for the cables to pass through.
• The mounting surface should be stable enough to protect the control head from
excessive wave shock and vibration.
• The mounting area should allow sufficient room so the control head can pivot
through its full tilt range.

Use the instructions in the following section to gimbal mount the control head on your boat.
NOTE: If you prefer to mount the Humminbird control head overhead, follow the instructions
in this section and install the gimbal bracket above the control head (see Install the Gimbal
