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'.
