SPECIAL PROCEDURES

Limp Home Mode

Monitoring System
To assist you when using the water-
craft, a system monitors the electron-
ic components of the fuel injection
system and some components of the
electrical system. When a fault oc-
curs, the cluster warning light will blink
with an audible signal to inform you
of a particular condition. Refer to the
TROUBLESHOOTING section for the
beeper coded signals 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, let-
ting 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 al-
low normal operation to come back.
These performance-reduced modes
allow the rider to go back home which
would not be possible without t his ad-
vanced system. If this occurs, see an
authorized SEA-DOO dealer as soon
as possible for inspection.

Engine Overheating

CAUTION: If the monitoring beeper
continuously sounds, stop engine
immediately.
Perform JET PUMP WAT ER INTAKE
AND IMPELLER CLEANING proce-
dure described in this section.

When back on shore, flush cooling
system, 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
WARNING
Keep away from intake grate while
engine is on. Items such as long
hair, loose clothing or person-
al flotation device straps could
potentially become entangled in
moving parts resulting in severe
injury or drowning.
Weeds, shells or debris can get caught
in the intake grate, drive shaft and/or
impeller. A clogged water intake may
cause troubles such as:
– Cavitation: Engine speed is high
but watercraft moves slowly due to
reduced jet thrust, jet pump compo-
nents may be damaged.
– Overheating: Since the jet pump
operation controls the flow of wa-
ter to cool the engine, a clogged in-
take will cause the engine to over-
heat and cause damage to internal
components.
A weed clogging area can be cleaned
as follows:
In-Water Cleaning
Rock the watercraft several times
while repeatedly pressing engine
start/stop button for short period with-
out starting engine. Most of the time,
this will remove the blockage. Start
engine and make sure water flows out
from bleed outlet and that watercraft
operates properly.
If the system is still blocked, take the
watercraft out of the water and re-
move blockage manually.
