| Install the Gimbal Bracket
1. Place the gimbal bracket in the chosen position on the mounting surface. Mark the four outer
mounting screw locations using a pencil or center punch.
NOTE: The outer set of mounting holes is recommended. You may use the inside set of
mounting holes if necessary. There may be additional, unused mounting holes on the gimbal
bracket.
2. Set the gimbal bracket aside. Drill the four mounting screw holes using a 5/32" (4 mm) drill bit.
3. Cable Hole: Mark and drill a 1" (25 mm) hole 2" to 4" (50 to 100 mm) behind the bracket. You
will use this hole for routing the cables to the control head in another section.
4. Place the bracket on the mounting surface aligned with the drilled holes. Fill the mounting
holes with marine-grade silicone sealant.
5. Place one flat washer onto each #10 x 1" wood screw. Insert the four screws with washers into
the mounting holes (see the illustration Installing the Gimbal Bracket). Hand tighten only!
