CAUTION
NEVER EXCEED THE MAXIMUM RECOMMENDED OPERATION
RPM OF THE ENGINES. MAINTAINING MAXIMUM OR CLOSE
TO MAXIMUM RPM FOR EXTENDED PERIODS CAN REDUCE
THE LIFE OF THE ENGINES.
Speedometer
Speedometers can indicate boat speed via the
engine pickup or an optional GPS or depth sounder
triducer, if these options are installed in your
boat. Refer to the engine display and electronics
operating manuals for more information on the
speedometer options available for your boat.
Temperature Gauge
The temperature gauge indicates the temperature
of the engine cooling system. A sudden increase
in the temperature could signal a blocked cooling
passage or a water pump malfunction.
CAUTION
CONTINUED OPERATION OF AN OVERHEATED ENGINE
CAN RESULT IN ENGINE SEIZURE. IF AN UNUSUALLY HIGH
TEMPERATURE READING OCCURS, SHUT THE ENGINE OFF
IMMEDIATELY. THEN INVESTIGATE AND CORRECT THE
PROBLEM

Oil Pressure Gauge
The oil pressure gauge monitors the engine lubri-
cation system pressure. The oil pressure indicated
when the engine is new is usually the reference
for normal oil pressure for that engine. A drop
in oil pressure is a possible indication of oil pump
problems, a leak or fuel diluted oil.
Fuel Gauge
The fuel gauge indicates the amount of fuel in
the fuel tank. This gauge is merely a relative
indication of the available fuel supply and not a
calibrated instrument.
Voltmeter
The voltmeter displays the voltage for the battery
and the charging system. The normal voltage is
11 to 12.5 volts with the engines off, and 13 to
14.5 volts with the engines running.
Hour Meter
The hour meter keeps a record of the operating
time for each engine.
Tilt/Trim Gauge
The tilt/trim gauge monitors the position of the
engines. The upper range of the gauge indicates
the tilt, which is used for trailering and shallow
water operation. The lower range indicates the
trim position. This is the range used to adjust
the hull angle while operating your boat on plane.
