Hand tighten only!
11. Snap open the assembly and hand-tighten the two mounting screws, then
snap the assembly closed.
NOTE: You will drill the third mounting hole and finalize the installation after you
route the cable and test and finish the installation in the following procedures.
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 (if it
is already connected). Make sure that the cable is long enough to
accommodate the planned route by running the cable over the transom.
