Phillips and a flat-head screw driver, an adjustable wrench, a level, and marine-grade silicone sealant.

Installation
Perform the procedures in the following sections to install the Wide Quick Disconnect mounting system on
your boat.
1.Determine Where to Mount
Begin the installation by determining where to mount the control head. Consider the following to determine
the best location:
• To check the location planned for the control head, test run the cables for power, transducer and
Temp/Speed accessory (if applicable).
• There are two ways to route the cables to the unit: through a hole in the mounting surface underneath
the mounting bracket, or from a hole outside the mounting bracket. Routing the cables under the
mounting bracket provides maximum weather protection; this may not be feasible, however, if the area
under the control head is inaccessible. In this case, route the cables through a hole at another location
and cover with the supplied hole cover.
• The mounting surface should be stable enough to protect the control head from excessive wave shock
and vibration, and should provide visibility while in operation.
• The mounting area should allow sufficient room for the unit to pivot and swivel freely, and for easy
removal and installation (see illustrations).

2.Drilling the Mounting Holes
1. Set the mounting bracket in place on the mounting surface. Mark the four mounting screw locations
with a pencil or a punch.
2. Set the mounting bracket aside, and drill the four mounting holes using a 9/64” drill bit. If you have
access to the underside of the mounting surface, mark and drill a 1” hole centered between the four
mounting screw holes.

3.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. 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.
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. Using needle-nose pliers, break
out the tabs on the rear of the mounting base. 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 9/64" (3.5 mm) bit, fill them with marine-grade silicone, then replace the Hole
Cover and insert the #8 Phillips countersink wood screws. Hand-tighten only.
NOTE: Remove the break-out tables only if the cable hole is not under the mount.
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.
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'. For assistance,
contact the Customer Resource Center at www.humminbird.com or call 1-800-633-1468 for more information.
