4. 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.
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. Make sure that the cable is
long enough to accommodate the planned route by running the cable over the transom.
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: The transducer can pivot up to 90 degrees in the bracket. Allow enough slack in the cable for this
movement. 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 procedure 5, Connecting 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.

3.
Place the escutcheon plate over the cable hole and use it as a
guide to mark the two escutcheon plate mounting holes. Remove
the plate, drill two 9/64" diameter x 5/8" deep holes, and then fill
both holes with marine-grade silicone sealant. Place the
escutcheon plate over the cable hole and attach with two #8 x 5/8"
wood screws.

NOTE: If there is excess cable that needs to be gathered at one location
(as shown in the illustration), dress the cable routed from both directions
so that a single loop is left extending from the storage location. Doubling
the cable up from this point, form the cable into a coil. Storing excess
cable using this method can reduce electronic interference.
