3.1.4 New Cable Clamping Arrangement
New decklead and projector cable clamping arrangements were introduced in 2017. The cable
clamps are designed to further enhance the robustness of the installed sonar head
3.1.4.1 Receiver cable clamp
There are two configurations for the decklead connection to the receiver. The standard comprises a
single cable with a push-on connector and the penetrator style, where there is a pigtail cable from a
moulded connection on the sonar housing. The receiver cable clamp is the same for both of the
configurations. There is a lower and upper bracket that comprises the clamp. The lower bracket is
positioned under the cables and aligned with the threaded holes along the top edge of the receiver.
The upper bracket is then positioned over the cables to mate to the lower bracket; the brackets are
secured with 6 M4 pan head Phillips screws. The M4 x 30mm screws secure the edge of the bracket
to the housing; the M4 x 16mm is used to secure the upper bracket to the lower bracket and do not
attach to the receiver housing.
In that there are different cable thicknesses, there are three available clamps depending on the
cable thickness.
