Boat Operation
Water Pressure Gauge
The water pressure gauge displays the pressure in the
engine’s cooling system. The gauge’s unit of measure
is pounds per square inch (PSI).
The water pressure gauge is a good indicator of cool-
ing system condition. Notice the readings at various
engine RPM and watch for any variation.
Refer to the engine operator’s manual for PSI ranges
for your engines.
Voltmeter
The voltmeter displays engine battery voltage mea-
sured in DC volts (VDC). Each engine has its own
battery and charging system.
These readings indicate that engine battery system is
in good condition:
• Key OFF: 0 volts
• Key ON, engine not running: 12 volts
• Engine running above idle: 14½ volts
Refer to the engine operator’s manual for additional
detailed information about the engine’s charging sys-
tem.
!
CAUTION
If the water pressure reading drops significantly
while the boat is on plane, stop the boat imme-
diately. Check the engine’s water intakes and
cooling system. If the engine is overheating,
continued operation could cause extensive
damage.
