HIGH ALTITUDE
OPERATION OF YOUR
OUTBOARD MOTOR
Your outboard motor is equipped with a carbu-
retor that is designed for proper engine opera-
tion at various altitudes up to 5000 feet (1500
meters) elevation. If you operate your outboard
motor at higher elevations, the change in air
pressure may affect the standard carburetor air-
fuel ratio and could make the engine run too
rich. This could decrease engine performance,
increase fuel consumption, cause difficult warm
starting, and may cause an increase in exhaust
gas emissions.
If you always operate your outboard motor at
altitudes above 5000 feet (1500 meters), an
alternative carburetor jetting specification is
available that will adjust the air-fuel ratio to
adjust for the change in air pressure resulting
from high-altitude operation. These parts are
available from Authorized Suzuki Marine Deal-
ers and are designed for correct operation in
your motor. If you need to apply these parts to
your outboard motor, Suzuki recommends that
you have them installed by an Authorized
Suzuki Marine Dealer, or a qualified service
professional.
NOTICE
If you operate an outboard motor at low
altitude (below 5000 feet (1500 meters))
when the engine has been modified for
high-altitude operation, the engine could
be damaged from overheating, or there
could be excessive exhaust gas emis-
sions.
Be sure to reinstall standard-specifica-
tion jetting in any outboard that has been
modified for high-altitude operation prior
to operating the outboard at low altitude
(below 5000 feet (1500 meters)).
OIL PRESSURE CAUTION
SYSTEM
This system operates when the engine lubricat-
ing oil pressure drops below the correct level.
If this system activates, the caution lamp on the
front of the motor will light.
On the remote control model, the buzzer in the
remote control box will simultaneously begin a
series of beep. When this system activates dur-
ing operation at over 2000 r/min, engine speed
will decrease gradually to approximately 2000
r/min and the engine will begin to run roughly.
This programmed rough-running condition is in
addition to the visible caution lamp.
If the lamp comes on, stop the engine immedi-
ately, if wind and water conditions make it safe
to do so.
 WARNING
If you attempt to remove or reinstall the
motor cover while the engine is running,
you may be injured.
To check the oil level, stop the engine and
then remove the motor cover.
