Route The Cable - Humminbird PiranhaMAX 197c Installation And Operation Manual

4. Route 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 Attach the Cables
to the Control Head
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 Humminbird Customer Service at humminbird.com or call
1-800-633-1468 for more information.
CAUTION! Do NOT mount the cables where the connectors could be submerged in
water or flooded. If cables are installed in a splash-prone area, it may be helpful to apply
dielectric grease to the inside of the connectors to prevent corrosion. Dielectric grease
can be purchased separately from a general hardware or automotive store
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"
(3.6 mm) diameter holes for the #8 x 5/8" (16 mm) 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" (16 mm) 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.
). Make sure that the cable is long enough to
