Routing the Cable
The transducer cable has a low profile connector, which must be routed to the
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 to reduce the possibility of interference. If the cable is
too short, extension cables are available to extend the transducer cable up to a total
of 50'. For assistance, contact the Customer Resource Center at www.humminbird.com
or call 1-800-633-1468 for more information.
NOTE: Allow enough slack in the cable for slight movement at the pivot point. It is
best to route the cable to the side of the transducer so the transducer will not
damage the cable during movement.
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.

2b. If you will be routing the cable through a hole in the transom, drill a 5/8"
diameter hole above the waterline. Route the cable through this hole, then
fill the hole with marine-grade silicone sealant and proceed to the next
step immediately.
