Bottom of Hull
5. Remove the transducer from the bracket and re-assemble it with the
cable passing through the bracket over the bolt as shown above. At-
tach the transducer to the transom. Slide the transducer up or down
until it's aligned properly on the transom as shown above. Tighten the
bracket's mounting screws. Adjust the transducer so that it's parallel to
the ground and tighten the lock nut until it touches the flat washer, then
add 1/4 turn. Don't over tighten the lock nut! If you do, the transducer
won't "kick-up" if it strikes an object in the water.
6. Route the transducer cable to the sonar unit. Make certain to leave
some slack inthe cable at the transducer as shown above. If possible,
route the transducer cable away from other wiring on the boat. Electri-
cal 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.
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
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. Don't allow the trans-
ducer bracket to go below the bottom of the hull!
