Select a mounting surface strong enough to support the weight of the unit and protect it from excessive vibration or shock. DO NOT mount the bracket in a location where the unit is exposed to extreme temperature conditions. When installing the mounting bracket, be sure to allow room for the connection and routing of the power cable. Tool List (not included)--drill, screwdriver (Phillips or standard), three #8 pan-head machine bolts with matching nuts and washers, and a 5/32" drill bit, OR three #8 pan head self-tapping screws, and a 1/16" drill bit. To mount the bracket assembly: 1. Using the swivel base as a template, mark the location of the three mounting holes. 2. If securing the base with machine bolts, drill three 5/32" holes at the locations you marked. If securing the base using selftapping screws, drill 1/16" starter holes at the locations you marked. Generally, starter holes should be no deeper than half the screw length. 3. Secure the swivel base with three bolts or screws. DO NOT OVERTIGHTEN. 4. Attach the swivel bracket and secure it with the short knob. Mounting Holes Swivel Base Short Knob Swivel Bracket and Base 2 Fishfinder 160C Owner's Manual INSTALLATION INSTRUCTIONS > TRANSDUCER INSTALLATION 1. Align the slot on the back of the unit with the long mounting knob and slide into place. It may be necessary to adjust the long knob to spread the bracket arms apart. (Turn counterclockwise to widen the bracket arms, clockwise to tighten.) 2. Adjust the unit angle and tighten the long mounting knob until snug. 3. Tilt the unit by loosening the long knob on the right side of the bracket assembly. 4. Rotate the entire bracket by twisting it left or right. (NOTE: You will hear clicks as you turn the bracket.) 5. Tighten all knobs when the viewing angle you want is obtained. To install the unit on the mounting bracket: Transducer Installation 1. Insert the rubber washer and plastic spacer in the transducer at the same time. DO NOT lubricate the rubber washer. 2. Route the cable toward the back and slide the transducer into the mounting bracket. 3. Place a 5 mm flat washer on the 10-32 x 1.75" screw and insert the screw through the mounting bracket, spacer, and rubber washer. 4. Place the remaining 5 mm flat washer on the exposed end, and install the 10-32 lock nut finger tight. The transducer is tightened further after installation on the boat. To assemble the transducer: Fishfinder 160C Owner's Manual 3 INSTALLATION INSTRUCTIONS > TRANSDUCER INSTALLATION Selecting a Transom Mount Location For your sonar to operate properly, the transducer has to be located in clean (non-turbulent) water. The transducer should be mounted as near the center of the boat as possible. DO NOT cut the transducer lead, this will void your warranty and may degrade the sonar's operation. DO NOT mount the transducer behind strakes, rivet lines, struts, fittings, water intake, discharge ports, eroding paint, or anything that creates air bubbles or causes the water to become turbulent. It is important that the transducer be as close to the center line as possible in calm, non-turbulent water for optimal performance. Avoid mounting the transducer in locations where the boat may be supported during launching, hauling, trailering, or storage. Mount the transducer away from the path of the prop on single drive boats. On twin drive ...
