OVER-REVOLUTION
LIMITING SYSTEM
This motor is equipped with a revolution limiting
system which activates when engine speed
exceeds 6000 r/min.
Over-revolution can result from cavitation when
turning hard, a propeller with a slipping bush or
worn-down blades, or a trim setting that is too
high.
If the over-revolution limiting system activates,
the motor will exhibit a rough running condition
and you must immediately reduce engine
speed to within the recommended operating
range.
NOTICE
If the Over-Revolution Limiting System
activates at recommended maximum
throttle and you are sure that the propel-
ler pitch is sufficient and there are no fac-
tors like "over-trimming" or "ventilation",
there may be a problem with the Over-
Revolution Limiting System.
Consult your authorized Suzuki marine
dealer if the Over-Revolution Limiting
System activates for no apparent reason.

OPERATION OF TILTING
SYSTEMS

TILT LOCK

When you shift the motor into "REVERSE"
gear, the motor will automatically lock so that it
will not lift out of the water due to forces such as
propeller thrust.
 WARNING
When the shallow water position is used,
the tilt lock will not work. As a result,
forces such as from propeller thrust dur-
ing operation in "REVERSE" gear, rapid
deceleration, and striking an underwater
object can cause the motor to lift out of
the water, resulting in personal injury.
When using the shallow water position,
proceed with caution and only at very low
speeds.
