put until you apply throttle again or you reach
trolling speed.
EJU33290Stopping the watercraft
The watercraft is not equipped with a sepa-
rate braking system. It is stopped by water re-
sistance when the throttle lever is released.
From full speed, the watercraft comes to a
complete stop in approximately 100 m (330 ft)
after the throttle lever is released or the en-
gine is stopped, although this distance will
vary depending on many factors, including
gross weight, water surface conditions, and
wind direction. The watercraft slows down as
soon as the throttle lever is released, but will
coast for a distance before fully stopping. If
you are not sure you can stop in time before
hitting an obstacle, apply throttle and turn in
another direction.
WARNING
EWJ00740
Allow adequate stopping distance.
Take early action to avoid collisions. Re-
member, watercraft and other boats do
not have brakes.
Operate defensively at safe speeds and
keep a safe distance away from people,
objects, and other watercraft to give you
time to stop.
Do not shut the engine off when slowing
down in case you need engine power tosteer away from a boat or other obstacle
that comes into your path.
Do not use the reverse function to slow
down or stop the watercraft as it could
cause you to lose control, be ejected, or
impact the handlebars.
EJU35960Beaching the watercraft
(1) Make sure that there are no boats, swim-
mers, or obstacles near the beach. Re-
lease the throttle lever about 100 m (330
ft) before you reach the intended beach-
ing area.
(2) Approach the beach slowly and stop the
engine before reaching land.
Remember, you need throttle to steer.
(3) Get off the watercraft and pull it up on the
beach.
CAUTION:
ECJ00490
Small pebbles, sand, seaweed, and other
debris can be sucked into the jet intake
and impair or damage the impeller. Always
stop the engine and get off the watercraft
before beaching it.
EJU36060Docking the watercraft
(1) Make sure that there are no boats, swim-
mers, or obstacles near the watercraft.
Reduce speed about 100 m (330 ft) away
from the dock.
(2) Slowly approach the dock and stop the
engine just before coming alongside it.
EJU33320Reverse on waterways
Reverse can be used for slow-speed maneu-
vering when it is necessary to back up out of
tight spots where you cannot turn around. Re-
verse can be used to slow down or stop only
during slow-speed maneuvering, such as
when docking.
