Gauges
Your Cobalt 360 Performance Cruiser is equipped
with two sets of gauges. The port set is for
monitoring operation of the port engine. The
starboard set is for monitoring operation of the
starboard engine. The gauges are illuminated for
night operation.
On occasion, a small fluctuation in a gauge
reading is not unusual. If an instrument reading is
outside the normal or recommended ranges,
determine the cause or see your Cobalt dealer.
Refer to the propulsion unit operator’s manual for
normal recommended ranges.
Fuel Level Gauge
Measures approximate level of fuel in a fuel tank.
The left gauge indicates the fuel level in the port
fuel tank. The right gauge indicates the fuel level
in the starboard fuel tank. The ignition switch must
be in the RUN position to activate the gauge.
Since the accuracy of your gauge varies with
attitude of your Cobalt
boat (trim and list), 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.
Tachometer
Registers engine speed in revolutions per minute
(RPM). Use this gauge to keep the engine within
the proper operating range. Consult your
propulsion unit operator’s manual for the proper
RPM operating range for your engines.
COB032
COB031
Speedometer
Registers forward speed in miles per hour. Use
this gauge to monitor fuel consumption and
propeller performance. Since its input is received
from a water pressure hose, accuracy is only
approximate.
Engine Synchronizer
Compares both engine RPMs. When the gauge
needle points to zero (straight up), the engines
are running at the same rate and are in “sync”
with each other. When the needle points to either
side of zero, one engine is operating at a higher
RPM than the other. The situation is corrected by
adjusting one or both throttles until the engines
are in sync and the needle points to zero.
