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

vated. The engine’s warning system automatically
limits its RPM when crankcase oil pressure falls be-

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
