If not equipped with Keyless Start System:
Each time the ignition key is turned to the "ON"
position, the alarm buzzer will sound for 2 sec-
onds.
NOTICE
If the Caution System is not working properly,
you may not be alerted to a condition that can
cause damage to your outboard motor.
If the buzzer does not sound when the ignition
key is turned to the "ON" position, the buzzer
may be broken or a failure may exist in the
system circuit. Consult your authorized
Suzuki marine dealer.
OVER-REVOLUTION CAUTION SYSTEM
This system is activated when engine speed
exceeds maximum recommended speed for
more than 10 seconds. In addition, "Rev Limit"
is displayed on screen.
If you continue to run, engine speed will auto-
matically be reduced to approximately 3000 r/min,
simultaneously the buzzer sounds. Then the
display will be changed into "Over Revolution".
36
The "Over Revolution" indication clears when
any of the button is pressed in the gauge.
This system must be reset by moving the throt-
tle to the idle position for about one second to
restore full engine operation.
NOTICE
If the Over-Revolution Caution System acti-
vates at recommended maximum throttle and
you are sure that the propeller pitch is suffi-
cient and there are no factors like "over-trim-
ming" or "ventilation", there may be a
problem with the Over-Revolution Caution
System.
Consult your authorized Suzuki marine dealer
if the Over-Revolution Caution System acti-
vates for no apparent reason.
OIL PRESSURE CAUTION SYSTEM
This system operates when the engine lubricat-
ing oil pressure drops below the correct level.
If this system activates, the "Low Oil Pressure"
and caution alarm icon are displayed on
screen, and the buzzer sounds. In addition,
when this system is activated at 1000 r/min. or
higher, engine speed will automatically be
reduced to approximately 1000 r/min.
If you continue to run, the engine will automati-
cally stop 3 minutes after beginning of the
above CAUTION system activation.
NOTE:
In case that the engine is automatically stopped
due to the CAUTION system, the engine can be
started again.
However the CAUTION system will repeatedly
activate until eliminating the cause.
