SPECIAL PROCEDURES

Jet Pump Water Intake and
Impeller Cleaning
WARNING
Keep away from intake grate while
engine is running. Items such as
long hair, loose clothing or per-
sonal flotation device straps can
become entangled in moving
parts.
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:
– 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 and exhaust
system, a clogged intake will cause
the engine to overheat and damage
engine internal components.
A clogged area can be cleaned as fol-
lows:
WARNING
If it is necessary to reach in to re-
move any foreign object caught in
the propulsion system, the tether
cord MUST BE REMOVED from the
engine cut-off switch
In-Water Cleaning
Rock the watercraft several times
while repeatedly pressing engine
START/STOP button for short periods
without starting the engine. Most of
the time, this will remove the block-
age. Start engine and make sure wa-
tercraft operates properly.
NOTE: If debris are denser than water,
stopping the engine should allow de-
bris to sink and clean the intake grate
automatically.

If the aforementioned method does
not work, the following can be per-
formed:
– With engine running and before ap-
plying throttle, pull the iBR lever in
to select reverse operation and vary
throttle quickly several times.
– Repeat procedure if necessary.
If system is still blocked, debris could
be lighter than water. In this case,
cleaning manually the intake grate
could be necessary.
iBR Override Function
When the iBR override function is acti-
vated, it allows the user to electrically
move the iBR gate and nozzle through
its full range of motion using the VTS
control button.
NOTE: The iBR override function is
only available when the engine is not
running.
WARNING
When moving the iBR gate using
the iBR override function, ensure
no-one is near the rear of the wa-
tercraft. Movement of the gate
may squeeze fingers.
NOTICE
An object or tool caught
in the iBR system when using the
iBR override function may cause
damage to the iBR components. Re-
move all rigid foreign objects that
may obstruct the iBR gate travel be-
fore moving it.
