Quick Disconnect Mounting Bracket

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.

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.
