ILLUSTRATIONS AND

PROCEDURES

The illustrations show the typical construction of

the different assemblies and, in all cases, may not

reproduce the full detail or exact shape of the parts

shown, however, they represent parts which have

the same or a similar function.

CAUTION: These sport boat are designed with

parts dimensioned mostly in the metric sys-

tem. However some components may be from

the imperial system. When replacing fasteners,

make sure to use only those recommended by

Bombardier.

As many of the procedures in this manual are in-

terrelated, we suggest that before undertaking

ENGINE EMISSIONS

INFORMATION

Manufacturer’s Responsibility

Beginning with 1999 model year engines, sport

boat manufacturers of marine engines must deter-

mine the exhaust emission levels for each engine

horsepower family and certify these engines with

the United States of America Environmental Pro-

tection Agency (EPA). An emissions control infor-

mation label, showing emission levels and engine

specifications, must be placed on each vehicle at

the time of manufacture.

Dealer Responsibility

When performing service on any 1999 and newer

Sea-Doo sport boat carrying an emissions control

information label, adjustments must be kept with-

in published factory specifications.

Replacement or repair of any emission related

component must be executed in a manner that

maintains emission levels within the prescribed

certification standards.

Dealers are not to modify the engine in any man-

ner that would alter the horsepower or allow emis-

sion levels to exceed their predetermined factory

specifications.
