1. DEPTH SOUNDER
Basic Depth Sounder Operation
TURN UNIT OFF:
Press and hold “MODE” for six
seconds.
TURN ALARM OFF:
Press “MODE.” Reactivate by
pressing “MODE” to display depth reading. To turn
off all alarms permanently, set “DEEP” and “SHAL”
to “0.”
DEEP ALARM:
Will sound if depth is greater than
deep mode setting. Press “MODE” to display
“DEEP,” press “UP” or “DOWN” arrows to adjust. “0”
for no alarm.
SHALLOW ALARM:
Will sound if depth is less
than shallow setting. Press “MODE” to display
“SHAL,” press “UP” or “DOWN” to adjust. “0” for no
alarm.
KEEL OFFSET:
This is the difference between the
transducer elevation and lowest point of the boat
(approximately 2 ft, set at -2 if desired). Press
“MODE” to display “KEEL,” press “UP” or “DOWN”
to adjust. Press “MODE” to return to normal
operation.
TEMPERATURE:
Press “UP” arrow for “A” (air
temperature) or “DOWN” arrow for “W” (water
temperature).
Refer to the Depth Sounder owner’s manual for
more information.
2. OIL (Engine Oil Pressure Gauge) -
Measures
the pressure of the engine’s lubricating oil, in
pounds per square inch (PSI). Refer to the engine
operator’s manual for correct specifications.
Many serious engine problems are reflected on oil
pressure gauge readings. If the pressure is lower
than the manufacturer's specification, immediately
shut off the engine. Have your authorized Cobalt
dealer correct the problem before operating the
engine.
3. TEMP (Engine Water Temperature Gauge) -
Indicates the water/coolant temperature inside the
engine. Refer to the engine operator’s manual for
normal operating temperature. After starting the
engine, check your temperature gauge for
abnormally high readings. If the reading is outside
the manufacturer’s operating range, immediately
turn off the engine. An abnormally high
temperature is the result of cooling water system
blockage. See your authorized Cobalt dealer when
experiencing a high engine temperature reading.
4. TACHOMETER -
Registers engine speed in
revolutions per minute (RPM). Use this gauge to
keep the engine within the proper operating range.
Refer to the engine operator’s manual for correct
specifications.
5. SPEEDOMETER -
Registers forward speed in
miles per hour. Since the speedometer input is
received from water pressure, accuracy is only
approximate.
6. VOLTS (Voltmeter) -
Indicates the condition of
the engine’s cranking battery in volts DC. With the
ignition switch on and the engine not running, a
reading between 11.5 and 12.5 volts indicates a
fully charged battery. With the engine running at
idle, the gauge should read between 10 and 12
volts. With the engine running at cruising speeds
and above, it should show 12 to 14 volts. See your
authorized Cobalt dealer and have the charging
system checked if the voltmeter reads below these
normal ranges.
7. FUEL (Fuel Level Gauge) -
Measures the
approximate level of fuel in a fuel tank.
The ignition switch must be in the RUN position to
activate the gauge. Since the accuracy of your
gauge varies with the attitude of your Cobalt boat,
and the fuel pick-up tube cannot withdraw all fuel
out of the tank, please observe the One Third Rule.
Use one third of your fuel to go out, one third to
come back and one third as a reserve.
8. TRIM (Trim Gauge) -
This gauge indicates the
angle position of the engines’ outdrive relative to
the position of the bow, up or down when boat is on
plane. Use this gauge in combination with the trim
switches located in the throttle control.
A
WARNING
Avoid injury or damage to the boat. DO
NOT use the depth sounder for
navigation.
