Routing the Cable
Thetransducer cable hasa low profile connector,which must berouted tothe
point where the control head is mounted. There are several ways to route the
transducer cable to the area where the control head is installed. The most
common procedure routes the cable through the transom into the boat.
NOTE: Your boat may have a pre-existing wiring channel or conduit that you can
use for the transducer cable.
1. Unplug the other end of the transducer cable from the control head.
(The transducer cable was connected in the earlier section Attaching
the Cables to the Control Head). Make sure that the cable is long
enough to accommodate the planned route by running the cable over
the transom.
CAUTION! Do not cut or shorten the transducer cable, and try not to damage the
cable insulation. Route the cable as far as possible from any VHF radio antenna
cables or tachometer cables toreduce the possibility of interference. If the cableis

NOTE: Allow enoughslack in the cable forslight movement at thepivot point. It is
best to route the cable to the side of the transducer so the transducer will not
damage the cable duringmovement.
2a. If you are routing the cable over the transom of the boat, secure the
cable by attaching the cable clamp to the transom, drilling 9/64"
diameter holes for #8 x 5/8" wood screws, then skip directly to step 5
to connect the cable.

fill the hole with marine-grade silicone sealant and proceed to the next
step immediately.
