SPECIAL PROCEDURES
Monitoring System
All Models except DI Models
To assist you when using the water-
craft, a system monitors some compo-
nent of the watercraft and sends audi-
ble signals through a beeper to inform
you of a particular condition. Refer to
the TROUBLESHOOTING section for
the coded signals chart.
Limp Home Mode
DI Models
Monitoring System
To assist you when using the water-
craft, a system monitors the electronic
components of the fuel injection sys-
tem and some components of the
electrical system. When a fault occurs,
it sends visual messages through the
information center and/or audible sig-
nals through a beeper to inform you of
a particular condition. Refer to the IN-
FORMATION CENTER for the displayed
messages and the TROUBLESHOOT-
ING section for the beeper coded sig-
nals chart.
Limp Home Modes
Besides the signals as seen above, the
system may automatically set default
parameters to the MPEM to ensure
the adequate operation of the water-
craft if a component of the fuel injec-
tion system is not operating properly.
Depending on the severity of the mal-
function, the watercraft speed may be
reduced and not allowed to reach its
top speed as usual. In this case, letting
the engine returning at idle speed may
allow normal operation to come back.
The engine RPM may be limited to idle
if some critical components fail. In this
case, removing and reinstalling the
safety lanyard on its post may allow
normal operation to come back.
These performance-reduced modes
allow the rider to go back home which
would not be possible without this ad-
vanced system. If this occurs, see an
authorized SEA-DOO dealer as soon as
possible for inspection.
Engine Overheating
All Models
CAUTION:
If the monitoring beeper
continuously sounds,
stop engine im-
mediately
.
Perform JET PUMP WATER INTAKE
AND IMPELLER CLEANING proce-
dure described in this section.
When back to shore, flush cooling sys-
tem, refer to POST-OPERATION CARE.
If engine still overheats, refer to an au-
thorized SEA-DOO dealer for servicing.
Jet Pump Water Intake and
Impeller Cleaning
Weeds, shells or debris can get caught
on the intake grate, drive shaft and/or
impeller. A clogged water intake may
cause troubles such as:
1.
Cavitation:
Engine speed is high but
watercraft moves slowly due to re-
duced jet thrust, jet pump compo-
nents may be damaged.
2.
Overheating:
Since the jet pump
operation controls the flow of water
to cool the engine, a clogged intake
will cause the engine to overheat
and damage engine internal compo-
nents.
WARNING
Keep away from intake grate while
engine is on. Items such as long
hair, loose clothing or personal flo-
tation device straps can become
entangled in moving parts result-
ing in severe injury or drowning.
