Principle Of Operation - BOMBARDIER SeaDoo Speedster 200 Operator's Manual

Take the following precautions when
trailering the craft:
Tie the craft to both bow and stern
(front/rear) eyelets so that it is firmly
retained on the trailer. Use additional
tie-downs if necessary.
– Remove stern light (if installed).
– Ensure that ski post is pushed down.
– Ensure all storage compartment cov-
ers are properly latched.
– A Sea-Doo cover can protect the
craft, particularly before driving on
dirt roads, to prevent dirt entering
through the air intake openings.
Observe trailering safety precautions.
CAUTION: Always ensure rear stor-
age compartment lid is closed and
securely fastened before trailering.

Principle of Operation

Propulsion
Each engine is directly coupled to a
drive shaft which, in turn, rotates an
impeller. This impeller is accurately ad-
justed in a housing where the water is
drawn up from underneath the sport
boat. Then, the water flows through
the impeller into a venturi. The venturi
accelerates the water and produces
thrust to move the sport boat. Pushing
the throttle levers forward increases
engine speed and therefore sport boat
speed.
With shift lever pushed forward, the
sport boat moves forward. In pulled
back position, the sport boat moves
backward. The middle position is neu-
tral and the sport boat is at the mini-
mum thrust for most conditions. Neu-
tral and reverse are achieved by means
of a gate, which is installed on the jet
pump venturi housings. These gates
direct the water flow to obtain the de-
sired direction.
WARNING
When the shifter is in the neutral
position, the impellers are turning.
62
WARNING
Shift lever should only be used
when the engines are idling and
craft is completely stopped.
TYPICAL
WARNING
Whenever an engine is to be start-
ed, the operator and passengers
should always be sitting in the
craft with the shifter lever in neu-
tral position and throttle levers in
idle position.
Steering
Turning the steering pivots the jet pump
nozzles which control the sport boat di-
rection. Turning the steering clockwise
will turn the sport boat to the right and
inversely.
TYPICAL — RIGHT-HAND TURN
Above idle speed, the throttles must
be applied to turn the sport boat.
