3. Adjust the height of the assembly so the face of
the transducer is 1/8" (3 mm) to 1/4" (6 mm)
beneath the bottom of the transom, and fully
tighten the three mounting screws.
4. In order to gain access to the mounting screws,
the transducer assembly must be pivoted up in the
bracket as shown. Be careful not to alter the

the assembly.
5. If access to the top mounting hole is not possible due to the selected
height of the transducer, fully tighten the two lower screws, then
simply remove the headed pivot pin and the transducer assembly,
and tighten the top screw, then reassemble.
6. Confirm that the pivot angle has not changed and that all mounting
screws are fully tightened.
To route the transom transducer cable:
The transducer cable has a low profile connector that 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 will be 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 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' (15 m). For assistance, contact the Customer Resource Center at
www.humminbird.com or call 1-800-633-1468 for more information.
NOTE: Since the transducer may need to pivot up to 90° in the bracket if it strikes
an object, make sure there is sufficient cable slack to accommodate this motion.
It is best to route the cable to the side of the transducer so the cable will not be
damaged by the rotation of the transducer.
2. If you will be routing the cable through a hole in the transom, drill a
5/8" diameter (16 mm) 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.
