If possible, route the transducer cable away from other wiring on the
boat. Use caution when routing the transducer cable around these
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 be 1". If you drill the hole, make
sure it is located above the waterline. After installation, be sure
to seal the hole with the same marine grade above- or below-
waterline sealant 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!
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.)
2. Slide the adjustable strap supplied with the TMB-S through the slot
in the transducer bracket and wrap it around the trolling motor. Po-
sition the transducer to aim straight down when the motor is in the
water. Tighten the strap securely.
