transducer. If possible, route the transducer cable away from other wir-
ing 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 transducer
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!
Trolling Motor Bracket Installation
1. Attach the optional TMB-S bracket to the transducer as shown in the
following figure, using the hardware supplied with the transducer.
(Note: The internal tooth washer is supplied with the TMB-S.)
