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.
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.
CAUTION! Do not cut or shorten the transducer cable, and try not todamage 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
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.
4. Route and secure the cable by attaching the cable clamp to the
transom; drill one 9/64" diameter x 5/8" deep hole, then fill the hole
with marine-grade silicone sealant, then attach the cable clamp
using a #8 x 5/8" screw.
5. Plug the other end of the transducer cable back into the control
head connection holder.
