ENGINE MONITORING
IMPORTANT: Your outboard must be equipped
"WATER TEMP" or HOT
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.
The engine is overheating. Serious engine damage
can occur quickly.
If the engine is overheating, it will also limit engine
speed to 2000 RPM. This additional protection fea-
ture is referred to as S.L.O.W.™ If the engine was
running faster than 2000 RPM when the S.L.O.W.
system activated, it will shake noticeably.
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.
IMPORTANT: Refer immediately to Engine Over-
heating.
Audible Driver Module (ADM)
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.
Your outboard may have been equipped with an
ADM in place of a System Check gauge. The ADM
controls the operation of the warning horn.
If the engine is overheating, the horn will sound
continuously and it will also limit engine speed to
2000 RPM.
