5. Attaching transducer to transom.
A. One-piece bracket: Remove the transducer from the bracket and re-
assemble it with the cable passing through the bracket over the bolt as
shown in the following figures.
For single-frequency Skimmer, route cable over bolt and through
bracket. Side view shown (left) and seen from above (right).
Both bracket types: Attach the transducer to the transom. Slide the
transducer up or down until it's aligned properly with the bottom of the
hull as shown in the preceding and following figures. Tighten the
bracket's mounting screws, sealing them with the sealant compound.
Adjust the transducer so that it's parallel to the ground and tighten the
nut until it touches the outer 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.
Align transducer centerline with hull bottom and attach transducer to
transom. Rear view of dual-frequency Skimmer shown.
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.
