Enjoy your watercraft
responsibly
You share the areas you enjoy when riding
your watercraft with others and with nature.
So your enjoyment includes a responsibility
to treat these other people, and the lands,
waters, and wildlife with respect and courte-
sy.
Whenever and wherever you ride, think of
yourself as the guest of those around you.
Remember, for example, that the sound of
your watercraft may be music to you, but it
could be just noise to others. And the exciting
splash of your wake can make waves others
won’t enjoy.
Avoid riding close to shoreline homes and
waterfowl nesting areas or other wildlife ar-
eas, and keep a respectful distance from fish-
ermen, other boats, swimmers, and
populated beaches. When travel in areas like
these is unavoidable, ride slowly and obey all
laws.
Proper maintenance is necessary to ensure
that the exhaust emission and sound levels of
your watercraft will continue to be within reg-
ulated limits. You have the responsibility to
make sure that the recommended mainte-
nance in this owner’s/operator’s manual is
carried out.
Remember, pollution can be harmful to the
environment. Do not refuel or add oil where a
spill could cause damage to nature. Remove
your watercraft from the water and move it
away from the shoreline before refueling. Dis-
pose of water and any fuel and oil residue in
the engine compartment according to local
regulations. And keep your surroundings
pleasant for the people and wildlife that share
the waterways: don’t litter.When you ride responsibly, with respect and
courtesy for others, you help ensure that our
waterways stay open for the enjoyment of a
variety of recreational opportunities.

Engine break-in
NOTICE
ECJ00432
Failure to perform the engine break-in
could result in reduced engine life or even
severe engine damage.
The engine break-in is essential to allow the
various components of the engine to wear
and polish themselves to the correct operat-
ing clearances. This ensures proper perfor-
mance and promotes longer component life.
To perform the engine break-in:
(1) Check the engine oil level. (See page 46
for information on checking the engine
oil level.)
(2) Launch the watercraft and start the en-
gine. (See page 62 for information on
starting the engine.)
