If the base of the transom has a radius, fill the gap between the tran-
som and the sensor with the caulking compound. 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 lo-
cated above the waterline. After installation, be sure to seal the
hole with the same marine grade above- or below-waterline seal-
ant used for the screws.
The sensor is now ready for use. Connect the sensor to the in-line con-
nector on the power/sensor cable. If you have any questions concerning
the installation of the sensor, please contact your local boat dealer.
POWER CONNECTIONS
The unit works from a twelve-volt battery system. For the best results,
attach the power cable directly to the battery. You can attach the power
cable to an accessory or power buss, however you may have problems
with electrical interference. Therefore, it's safer to go ahead and attach
the power cable directly to the battery.
