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.

noticeably and will not exceed 2000 RPM (fast idle),
the low oil pressure warning might have been acti-
vated. The engine’s warning system automatically
limits its RPM when crankcase oil pressure falls be-
low what the engine requires.
Oil pressure can fall due to operating conditions
such as rough seas. or it can fall in response to in-
sufficient supply of oil. Once the engine’s warning
system has been activated, you must take appropri-
ate action to restore adequate oil pressure and re-
set the warning system before the engine can
operate normally.
For information about evaluating low oil pressure
and possible “on-the-water” fixes, refer to Low Oil
Pressure Warning.
