IMPORTANT: Indicates supplementary infor-
mation which may be needed to fully com-

FOREWORD
SAFETY INFORMATION
Reminders Regarding Operation
Engine exhaust contains carbon monoxide
(CO), which can cause injury or death if in-
haled in sufficient quantities. Educate all oc-
cupants about the risks and symptoms of CO
accumulation and CO poisoning. For more in-
formation, refer to CARBON MONOXIDE
AND BOATING section.
Gasoline vapors can explode, resulting in in-
jury or death. Always use blower for a mini-
mum of 5 minutes before starting engine, then
turn it OFF above idle speed. Use of the bilge
blower should never replace “smelling” for
gasoline vapor odors.
If at any time, gasoline leaks/odors are found,
do not start the engine. Have the boat ser-
viced by an authorized Rotax Jet Propulsion
marine engine dealer.
Always keep in mind that as the throttle lever
is returned to the idle position, less directional
control is available. To turn the boat, both
steering and throttle are necessary.
This boat has no brake. Stopping distance will
vary depending on initial speed, load, wind,
and water conditions. Practice stopping and
docking in a safe, traffic-free area to have an
idea of how long it will take to stop the boat
under varying conditions. Do not release the
throttle when trying to steer away from ob-
jects. You need throttle to steer. Do not use
the boat's reverse to stop.
Do not start or operate the boat if any person
is not properly seated in a seat intended for
use when underway (refer to boat labels) or if
a person is nearby in the water.
The boat's jet thrust can cause injury. Always
accelerate slowly, and decelerate in a con-
trolled fashion.
Observe the instructions on all safety labels.
They are there to help assure that you have a
safe and enjoyable outing.
Riding with passenger(s) or pulling other
boats, tubes, a skier or a wakeboarder makes
the boat handle differently and requires great-
er skills.
In shallow water, proceed with caution and at
very low speeds. Grounding or abrupt stops
may result in injury to you, your passengers or
others. The jet pump may pick up debris and
throw it rearward causing a risk of injuring
people or damaging the jet pump or other
property.
Combustion engines need air to operate; con-
sequently this boat can not be totally water-
tight. Any maneuvers such as figure eights
that cause the upper deck to be under water
may cause severe engine problems due to
water ingestion. Refer to the SPECIAL PRO-
CEDURES and WARRANTY sections con-
tained in this Operators Manual.
Respect no wake zones, the rights of other
water users and the environment. As the
“skipper” and owner of a boat, you are re-
sponsible for damage to other boats caused
by the wake of your boat. Do not let anyone
throw refuse overboard.
Between sunset and sunrise, use the boat's
navigation lights and reduce speed. Do not
operate the boat in reduced visibility.
Do not add accessories or equipment that
may adversely affect visibility or alter control
of the boat.
The skipper should personally take the helm
during storms.
WARNING
Avoid personal injury! Do not allow any-
one near the jet pump or intake grate,
even when the engine is off. Items such
as long hair, loose clothing or personal
flotation device straps can become
entangled in moving parts resulting in
serious injury or drowning. In shallow
water, shells, sand, pebbles or other
objects could be drawn up by the jet
pump and be thrown rearward.

ponent with a defect in materials or workmanship that would increase the engine’s emissions
