6. Route the transducer cable through or over the transom to

the sonar unit. Make sure to leave some slack in the cable at the

transducer. 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.

WARNING:

Clamp the transducer cable to the transom close to the

transducer. This can prevent the transducer from enter-

ing the boat if it is knocked off at high speed.

If you need to drill a hole in the transom to pass the connector through,

the required hole size is 5/8". (If you intend to route an additional speed

or temp sensor cable through the same hole, you will need a 1" (25.4 mm)

drill bit instead.)

Caution:

If you drill a hole in the transom for the cable, make sure it is lo-

cated above the waterline. After installation, be sure to seal the

hole with the same marine grade above- or below-waterline seal-

ant used for the mounting screws.

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 trans-

ducer bracket down. This puts the transducer deeper into the water,

hopefully below the turbulence causing the noise. Don't allow the

transducer bracket to go below the bottom of the hull!
