Transom
If the base of the transom has a radius, fill the gap between the
transom and the sensor with the sealant. This will help ensure a
smooth water flow.
Route the sensor's cable through or over the transom to the sonar unit.
If you need to drill a hole in the transom to pass the connector through,
the required hole size is 7/8".
CAUTION:
If you drill a hole in the transom for the cable, make sure it is
located above the waterline. After installation, be sure to seal the
hole with the same marine grade above- or below-waterline
sealant used for the screws.
The sensor is now ready for use. Connect the sensor to the sonar socket
on the back of your unit and connect the transducer to the speed
sensor's socket. If you have any questions concerning the installation of
the sensor, please contact your local boat dealer.

Power Connections

Your unit comes with a power/data cable that splits into three ends,
each with several exposed wires (shown in the following figure). The
end with 4 wires (blue, yellow, orange and shield) is a data cable that
connects to a NMEA 0183 interface; the cable label says "RS-232
COMM". The end with three wires (red, black and shield) is a power
cable that supports a NMEA 2000
