ENGINE MONITORING
IMPORTANT: Your outboard must be equipped
"NO OIL"
with the System Check® (or equivalent) engine
monitor. Operating your outboard without the Sys-
tem Check (or equivalent) engine monitor will void
your warranty for failures related to the functions
monitored on your engine.
There is an oil delivery problem. Serious engine
damage can occur quickly. If you must operate your
outboard to reach safety, do not exceed 1500 RPM.
If you want to continue to operate your outboard be-
fore repairs are made, check the oil tank for con-
tents and condition.
When you turn the key switch ON, the System
Check engine monitor horn performs a self-test by
sounding a 1/2-second beep. The gauge self-tests
by turning the warning lights on, then off in se-
quence. During engine start-up, pause with the key
switch in the ON position to observe the horn and
gauge perform the self-test. If the self-test does not
happen as stated, see your DEALER.
The System Check engine monitor alerts the oper-
ator with a 10-second beep of the horn and a warn-
ing light on the gauge when certain engine
problems occur. The appropriate warning light
will stay on until the key switch is turned OFF.
If the oil tank is empty;

Add the recommended oil to the oil tank; and
Add oil to the fuel tank at the correct ratio until the
oil system can be purged of air.
IMPORTANT: Serious engine damage will occur if
you operate the engine after the oil supply is ex-
hausted. Never run the oil tank dry. If the tank is run
dry, you must purge the oil system of air. Refer to
Oil System.
If the oil tank is not empty, add oil to the fuel tank
at the correct ratio. Refer to Fuel and Oil.
Have your DEALER check the condition of your
outboard’s oil injection system. Your DEALER will
check for air and oil leaks, damaged components or
a clogged oil filter. Your DEALER should verify oil
supply before returning your outboard to normal op-
eration.
"WATER TEMP" or HOT
The engine is overheating. Serious engine damage
can occur quickly.
If the engine is overheating, it will also limit engine
speed to 2500 RPM. This additional protection fea-
ture is referred to as S.L.O.W. If the engine was
running faster than 2500 RPM when the S.L.O.W.
system activated, it will shake noticeably.

"LOW OIL"
Oil in the oil tank is at “reserve” level (about 1/4 full).
Fill the oil tank with recommended oil as soon as
possible to avoid emptying the tank. Refer to Filling
the Oil Tank.
