Propulsion System
Some or all of the following gauges may be
present.
Tachometers
The tachometers display the speed of the engines in
revolutions per minute (RPM). This speed is not the
boat speed or necessarily the speed of the propeller.
The tachometer display also contains the engine
trim meters, oil pressure indicator, water pressure,
water temperature, volt meters and the overheat
warning indicator.
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 gauge and electronics operating manuals
for more information on the speedometer options
available for your boat.
Overheat Warning Indicator
The temperature warning indicates that the tem-
perature of the engine is too high. A sudden
increase in the temperature could indicate an
obstructed water inlet or an impeller failure. On
Yamaha engines the overheat warning indicator
is built into the LCD display. It will start to blink
and sound an alarm if the engine temperature is
too high.
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
