2006 Johnson 30 hp PL4 4-Stroke Outboard Owners Manual

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.
“NO OIL” or “LOW OIL”
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,  during  operation,  your  engine  begins  vibrating
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.
