ENGINE MONITORING
IMPORTANT:  Your  outboard  must  be  equipped
with  the  SystemCheck™  (or   equivalent)  engine
monitor. Operating your outboard without the Sys-
temCheck (or equivalent) engine monitor will void
your warranty for failures related to the functions
monitored on your engine.
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 SystemCheck engine monitor alerts the opera-
tor with a 10-second beep of the horn and a warning
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 engine  management module (EMM)  senses
that  the  problem  could  cause  permanent  engine
damage,  it  will  also  limit  engine  speed  to  3000   mal operation. Serious engine damage can occur
RPM. This additional protection feature is referred
to as S.L.O.W.™  If the engine  was running faster
than 3000 RPM when the S.L.O.W. system activat-
ed, it will shake noticeably.
