Sonar Unit Mounting

6.Route the transducer cable to the sonar unit. If possible, route the transducer cable away from other wiring on the boat. Electrical noise from the engine’s wiring, bilge pumps, VHF radio wires and cables, and aerators can be picked up by the sonar. Use caution when routing the transducer cable around these wires.

IMPORTANT!

Clamp the transducer cable to the transom close to the transducer. This can prevent the transducer from entering the boat if it is knocked off at high speed.

7.Make a test run to determine the results. If the bottom is lost at high speed, or if noise appears on the display, try sliding the transducer bracket down. This puts the transducer deeper into the water, hope- fully below the turbulence causing the noise. Do not allow the trans- ducer bracket to go below the bottom of the hull!

Install the X-70A 3D in any convenient location, provided there is clear- ance behind the unit when it is tilted for the best viewing angle. Holes in the bracket base allow wood screw or through-bolt mounting. Make cer- tain there is enough room behind the unit to attach the power and trans- ducer cables.

Using the bracket as a template, mark the dash for the mounting holes, then make a mark in the center of the bracket location for the cable hole. If you want the smallest possible hole for the power and transducer cables in the dash, install the transducer first, then route the cable to the desired location. The smallest hole that will pass one power or transducer plug is 5/8". After the hole is drilled, pass the transducer connector up through the hole first, then pass the power cable down through it.

After routing the cables, fill the hole with a good marine sealing com- pound. Place the bracket over the hole and route the cables through the slot in the back of the bracket. Break out one of the other slots for the transducer cable. Screw the bracket to the dash.
