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 watercraft are designed with

parts dimensioned mostly in the metric sys-

tem. However some components may be from

the imperial system. When replacing fasten-

ers, make sure to use only those recommended

by BRP.

As many of the procedures in this manual are inter-

related, we suggest, that before undertaking any

task, you read and thoroughly understand the en-

tire section or subsection in which the procedure

is contained.

A number of procedures throughout the book re-

quire the use of special tools. Before undertaking

any procedure, be sure that you have on hand all

the tools required, or approved equivalents.

TYPICAL

To remove carburetors from engine, proceed as fol-

lows:

Remove air vent tube support.

Unlock retaining slides holding air intake silencer base.

Remove air intake silencer base from watercraft.

Remove screws holding flame arrester base support

to cylinder head cover.

Unscrew base retaining screws then remove base from

carburetors and move to front of watercraft.

Turn the valve to OFF position.

NOTE: For fuel line removal, use pliers (P/N 295

000 054).

Disconnect pulse line from fuel pump.

Disconnect fuel fuel supply line from fuel pump.

Disconnect fuel return line.

Disconnect oil injection pump cable, throttle cable and

choke cable.

Remove screws no. 6 and lock washers no. 7 retaining

carburetors.

All Others Models

Remove 4 bolts no. 8 and lock washers no. 12 from

rotary valve cover then move carburetors and rotary

valve cover on top of engine.

NOTE: When removing rotary valve cover , pay

attention that the rotary valve stay in place, other-wise

it must be timed.

Remove carburetors from intake manifold.

Disconnect fuel bypass line between carburetors (twin

carburetors).

Remove carburetor(s) from rotary valve cover.

DISASSEMBLY AND INSPECTION

Using a suitable pump gauge tester, perform the fol-

lowing test proceeding as follows:

- Install pump gauge tester (P/N 295 000 083) on pulse

nipple.

- Pump tester until it reaches 28 kPa (4 PSI).

Diaphragm must stand pressure for 10 seconds. If

pressure drops, replace diaphragm.

INTRODUCTION

ENGINE EMISSIONS

INFORMATION

Manufacturer's Responsibility

Beginning with 1999 model year engines, PWC

manufacturers of marine engines must determine

the exhaust emission levels for each engine horse-

power family and certify these engines with the

United States of America Environmental Protec-

tion Agency (EPA). An emissions control informa-

tion label, showing emission levels and engine

specifications, must be placed on each vehicle at

the time of manufacture.

Dealer Responsibility

When performing service on all 1999 and more

recent Sea-Doo watercrafts that carry an emis-

sions control information label, adjustments must

be kept within 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.

Exceptions include manufacturer's prescribed

changes, such as altitude adjustments for exam-

ple.

Owner Responsibility

The owner/operator is required to have engine

maintenance performed to maintain emission

levels within prescribed certification standards.

The owner/operator is not to, and should not al-

low anyone to modify the engine in any manner

that would alter the horsepower or allow emis-

sions levels to exceed their predetermined factory

specifications.

EPA Emission Regulations

All new 1999 and more recent Sea-Doo water-

crafts manufactured by BRP are certified to the

EPA as conforming to the requirements of the

regulations for the control of air pollution from

new watercraft engines. This certification is con-

tingent on certain adjustments being set to factory

standards. For this reason, the factory procedure

for servicing the product must be strictly followed

and, whenever practicable, returned to the origi-

nal intent of the design.

The responsibilities listed above are general and

in no way a complete listing of the rules and regu-

lations pertaining to the EPA requirements on ex-

haust emissions for marine products. For more

detailed information on this subject, you may con-

TIGHTENING TORQUES

Tighten fasteners to torque mentioned in explod-

ed views and/or text, When they are not specified,

refer to following table.



WARNING

Torque wrench tightening specifications

must strictly be adhered to. Locking devices

(ex.: locking tabs, elastic stop nuts, self-lock-

ing fasteners, etc.) must be installed or

replaced with new ones, where specified. If

the efficiency of a locking device is impaired,

it must be renewed.

In order to avoid a poor assembling, tighten

screws, bolts or nuts in accordance with the

following procedure:

– Manually screw all screws, bolts and/or nuts.

– Apply the half of the recommended torque value.

CAUTION: Be sure to use the proper tightening

torque for the proper strength grade.

NOTE: When possible, always apply torque on the

nut.

– Torque to the recommended torque value.

NOTE: Always torque screws, bolts and/or nuts in

a criss-cross sequence.
