Testing the Transom Mount Installation
Perform this test after you install the Fishfinder. Because you need
water to carry the sonar signal, the Fishfinder does not function
properly with the transducer out of the water. When you place your
boat in the water, check for leaks around the screw holes that are
below the water line. DO NOT leave your boat in the water for an
extended period of time without checking for leaks.
To test the transom mount installation:
1. Begin testing the installation at a slow speed. If the sonar
appears to be working properly, gradually increase the boat’s
speed observing the sonar’s operation. If the sonar signal
suddenly is lost or the bottom return is severely degraded,
note the speed at which this occurs.
2. Return the boat to the speed at which the signal was lost.
Make moderate turns in both directions and see if the signal
improves.
3. If the signal strength improves while turning, adjust the
transducer so that it extends another 1/8" below the transom
of the boat. It might take several adjustments to eliminate the
degradation.
4. If the signal does not improve it may be necessary to move
the transducer to a different location.
Installing the Wiring Harness
The Fishfinder 160C comes with a wiring harness that connects
the unit to power and the transducer with one easy-to-remove
connection. If it is necessary to extend the power wires, use 22
AWG wire. DO NOT cut the transducer cable, because this will void
your warranty. Transducer extension cables are available from your
Garmin Dealer.
If your boat has an electrical system, it may be possible to wire the
unit directly to an unused holder on your current fuse block. If you
are using the boat’s fuse block, remove the in-line fuse supplied with
the unit. You can also wire the unit directly to the battery.
To install the wiring harness:
1. Install the Red (+) wire on the positive battery terminal.
2. Install the Black (-) wire on the negative battery terminal.
3. Install a 2 Amp fuse in the fuse holder (fuse block only).
4. Align the notches on the cable plug and back of the unit.
Insert the cable into the connector and turn the lock ring
counter-clockwise until it stops.
The Fishfinder 160C outputs NMEA data for: Water Depth, Water
Speed and Water Temperature.
To connect the NMEA output to a NMEA device:
Connect the Blue wire to the Data Input of the NMEA device.
