Appendix A: Certified Engines

Certified engines

The following information concerns engines certified for
European use on Lake Constance and in Switzerland.
All Volvo Penta engines and products have been developed
on the basis that they should have as little an impact on
the environment as possible. However, national and regional
environmental legislation is different for all the markets where
Volvo Penta sells its products. Sometimes legislation de-
termines that we have to build special engines, or that the
engine must be approved in advance and certified by the
authorities.
The fact that the engine is certified means that Volvo Penta,
as the engine manufacturer, ensures that all the engines it
manufactures meet the sample engine approved for certifi-
cation. Certification does not just cover requirements with
respect to factory-new engines: Certified engines already
in operation must also be able to meet environmental re-
quirements. Certain requirements with respect to servicing
and spare parts must be met in order that Volvo Penta as
engine manufacturer will be able to assume responsibility
for engines in operation.
Volvo Penta does not advise you against carrying out ser-
vice yourself. In fact, Volvo Penta views it as an advantage
because you have the opportunity to find out quickly whether
any components are not working or are working abnormally.
However, special expertise, service manuals, special tools
and other suitable equipment are required in order to be
able to perform some service checks. Only an authorized
Volvo Penta service dealer must carry out these service
checks. Always contact your Volvo Penta dealer if you are
unsure of anything to do with your engine's function or
maintenance.
Those of you who own or maintain a certified Volvo Penta
engine must be aware of the following:
• Service intervals and maintenance by Volvo Penta must
be adhered to.
• Only Volvo Penta genuine parts intended for certified
engine may be used.
• An authorized Volvo Penta service dealer must always
service the ignition system (ignition timing) and the fuel
injection system.
• The engine must not be rebuilt or in any way modified,
with the exception of the accessories and serviceable
units developed for the engine by Volvo Penta.
• Changes to the installation of exhaust pipes and intake
air ducts to the engine compartment (ventilation ducts)
68
must not be implemented, as this may affect exhaust
emissions.
• Unauthorized personnel must not break any seals
present.
NOTE!
Use only Volvo Penta genuine parts when you need
spare parts. Using non-genuine parts means that AB
Volvo Penta can no longer assume responsibility for
an engine meeting the certified design. Volvo Penta
will not assume any responsibility for any kind of
damage or costs due to non-genuine Volvo Penta
service parts being used for the product in question.
Bodensee Shiffahrts Ordnung (BSO)
number
Your engine may have an assigned Bodensee Shiffahrts
Ordnung (BSO) number. A BSO number is assigned to an
engine model when it is certified for European use on Lake
Constance and in Switzerland. There are two BSO certifi-
cation decals placed on the engine, one on the starboard
high-rise bracket and the other on the front of the port cylin-
der head to verify engine certification. These decals must
be maintained so engine certification can be verified in the
future.
When an emissions check is required, the plug located on
either high-rise elbow can be removed for installation of a
test probe.
