Throttle and Choke Cable
Inspection
Throttle Cable
Depress and release the throttle lever.
It should operate smoothly and return
to its initial position without any hesi-
tation. Refer to an authorized Sea-Doo
dealer if necessary.
Carburetor-Equipped Models
Do not activate throttle lever unneces-
sarily, when engine is not running. Car-
buretors are equipped with fuel accel-
erator pumps. These pumps deliver
fuel to the engine each time throttle
lever is depressed.

Carburetor-Equipped Models
Choke Cable
Ensure choke cable operates smooth-
ly and without any hesitation from fully
opened to fully closed. When the
choke lever is fully pulled, choke
should be fully applied. Refer to an au-
thorized Sea-Doo dealer if necessary.
Carburetor Adjustment
Carburetor adjustment is very impor-
tant to allow good engine operation and
therefore watercraft performance. Car-
buretor adjustment requires technical
knowledge and experience to have the
correct mixture supplied to the engine.
CAUTION:
Serious engine damage
can occur with improper carburetor
adjustment.
Fuel Injection System
DI Models
The fuel injection system inspection
should be performed by an authorized
Sea-Doo dealer.
CAUTION:
Never use injector clean-
ing products. They may contain ad-
ditives that could damage injector
components.
All Models
Fuel and Oil Filters
The fuel filter (
carburetor-equipped
models
) and the oil filter should be re-
placed by an authorized Sea-Doo deal-
er.
Fuel system pressurization
should
be conducted at the same time.
CAUTION:
An obstructed oil filter
will cause oil starvation resulting in
serious engine damage.
Steering Alignment
When the handlebar is directed in
straight ahead position, the jet pump
nozzle should be in the same direction
allowing the watercraft to run in a
straight line.
Refer to an authorized Sea-Doo dealer
if an adjustment is necessary.
WARNING
Do not alter or tamper with throt-
tle cable adjustment or routing.
WARNING
If throttle lever does not automat-
ically return, do not operate
water-
craft

Doo dealer.
