Safety
precautions
Exhaust gas
Exhaust gases contain carbon
monoxide. This colourless and
odourless gas is extremely harmful and could lead to poisoning
which could result in loss of
consciousness or death. The first
symptoms of carbon monoxide
intoxication are as follows:
• Dizziness
• Nausea
• Headache
• Throbbing temples
• Vomiting
• Fatigue and falling asleep
• Tense muscles
If you or anyone else in the vicinity
of the engine experiences any of
these symptoms, leave the area
of operation of the engine and find
fresh air. If the symptoms persist,
consult a doctor and have the engine checked.
Ensure the exhaust circuit correctly
expels the gas produced by the
engine. Regularly check that the
exhaust circuit is free of leaks and
that the exhaust elbow is in good
condition.
Burns
Never touch the hot parts of the
engine! An operational engine gets
very hot: the exhaust system, turbocompressor (if equipped), starter,
oil sump, oil, coolant in the hoses
and pipes are hot and can burn.
Fluids ejected under pressure can
cause serious injury. Release all
the pressure in the circuits before
removing the caps. Never open the
oil circuit and coolant caps when
the engine is operational and/or
hot. Never start or run the engine
when the oil fill and coolant caps
are not screwed on as hot oil or
coolant could spray out.
If you come into contact with any
of these fluids, consult a doctor
immediately. If the engine gets too
hot, switch it off and disconnect it
and wait for it to cool down before
checking for failure.
Fire
Do not smoke near the engine and
keep it away from sources of ignition (flames or sparks) or any other
potential flammable vapour or liquid
sources. Do not run the engine
without the air filter.
Do not run the engine in an area
in which flammable or explosive
materials are stored or where gas
is present. Ensure there are no
flammable liquids in the engine
compartment.
5
Immediately clean up any liquids
spilled and keep the engine compartment clean and accessible so
as to minimise the risk of fire. Be
careful as fuel can burn. Damaged
pipes can lead to fire.
Explosion
Explosions caused by fuel vapour
can cause serious injury! Carefully
follow the safety rules when filling
the fuel.
Open and ventilate the storage
area of the engine after filling.
Check that there are no fuel vapours or leaks before starting the
fan (if fitted). Switch the fan on for 5
minutes before starting the engine.
All fuel vapours are flammable
and explosive. Be careful when
handling and storing fuel. Store
the fuel in a ventilated area away
from sources of ignition (sparks
or flames) and out of the reach of
children.
Stop the engine before filling with
fuel or lubricant. Do not smoke near
the engine and keep it away from
sources of ignition (flames) when
filling with fuel and/or lubricant.
Wear gloves when investigating
possible leaks.
Do not alter or damage the fuel circuit. Close the fuel circuit whenever
you work on it. Ensure you always
have an appropriate working fire
extinguisher to hand.
Hazardous Voltage/
Electrical Shock
Electrocution is possible whenever
electricity is present. Hazardous
voltage can cause severe injury
or death. Operate the engine only
when all guards and electrical enclosures are in place.
Open the main circuit breakers
of all power sources before servicing the equipment. Configure the
installation to electrically ground the
engine, transfer switch, and related
equipment and electrical circuits to
comply with applicable codes and
standards.
Never contact electrical leads or
appliances when standing in water
or on wet ground because these
conditions increase the risk of
electrocution. The voltage at these
terminals can cause death.
Short circuits can cause bodily
injury and/or equipment damage
Remove all jewellery before servicing the equipment.
Hazardous backfeed voltage can
cause severe injury or death.
Connect the engine to the building/marina electrical system only
through an approved device. Work
on the electrical circuit should only
be carried out by qualified technicians.
Operations on the shore power
equipment must only be carried out
by electricians authorized to work
with high voltage installations.
6
Special attention must be brought
on boat with metallic hull, especially
concerning the protection of the
persons against electrical shock
and the protection against galvanic
and electrolytic corrosion.
Battery acid
The acid in batteries can cause
serious injury and even death!
When servicing the batteries, wear
protective gloves and goggles. Batteries contain sulphuric acid which
is highly corrosive.
Acid can spurt from batteries when
they are handled. If the acid comes
into contact with the skin, rinse thoroughly in fresh water and consult
a doctor.
Risk of battery explosion
A battery explosion can cause
serious injury and even death! Ensure the battery storage compartment is corrected ventilated.
Do not smoke near the batteries
and keep them away from sources
of ignition (flames or sparks). They
produce hydrogen which could
ignite or explode on contact with an
electrical arc or a flame.
Switch off all electrical appliances
in the vicinity when you are working
on the batteries.
Ventilate correctly storage batteries
compartment. Avoid touching the
battery terminals with metal tools
so that no sparks are created which
could cause an explosion. Remove
the rings, bracelets and necklaces
before handing the batteries.
Rotating parts
Rotating parts can be extremely
dangerous and cause serious injury
and even death!
Do not work on the engine when
it is operational. If work on the
engine when running is absolutely
necessary, do not touch any hot or
rotating parts.
Baggy clothing, hair or objects
could be pulled in and/or caught
and cause serious injury or substantial property damage.
Do not wear bracelets, necklaces
or rings when working on a engine.
Check that the bolts and screws
are properly tightened and that
the protection mechanisms are in
place. Do not check the tension of
the alternator belt when the engine
is operational.
7
Accidental starting
Accidental starting can cause serious injury and even death!
Disconnect the battery before working on the engine. Ensure no one
is alongside the engine or working
on before starting it. A rotating
propeller can cause serious injury
or death. Ensure all the protection
mechanisms are in place before
starting the engine.
Chemical products
The different fluids used to run the
engine are a health hazard. Carefully read the instructions on the
packaging of these products and
always check that the ventilation in
the hold space is adequate.
Follow environmental regulations
concerning the disposal of oil, fuel,
coolant, filters and batteries. Do
not put your hands over pipes when
looking for possible leaks.
Water ingress
The engine should be protected
against from water ingress by any
means. Water ingress leads to
complete engine failure. This is not
cover under any warranty terms.
Water can enter the engine after
filling the exhaust system.
Correct installation of the engine on
your boat is of the greatest importance for safe navigation and pro-
tection of the environment. The first
protection against water ingress is
a correct installation of the engine.
A correct use of the engine is also
important to protect the engine
against water ingress. The operator/owner is responsible for the
correct operation of the engine and
for the implementation of all necessary means to protect the engine
against water intrusion.
After a vessel capsizing, or if the
engine has been filled with water,
do not start the engine, except in
extreme emergencies, and contact
an authorized Nanni dealer.
8
About the engine
Engine identification
Both the engine and the transmission has an identification plate that
contain several informations.
Keep these plates accessible and
in good condition. Record and keep
the engine and transmission serial
number and designation. These
numbers should always be quoted
when ordering service and replacement parts.
The engine identification plate is as
follow:
• TYP indicates the commercial
designation of the engine.
• NR indicates the engine serial
number.
• CODE lists various specifications
of the engine.
Break in
Operate the engine with care for
the first 50 hours of operation.
Do not race the engine while it is
cold. Do not operate it at full load
except for short periods. Never
run the engine at constant engine
speed for long periods during the
break in period.
Check the oil and coolant level
frequently during the running-in
period. The oil consumption can be
more important during the runningin period.
Engine installation
The installation must be carried out
by an authorized Nanni workshop
in accordance with the installation
instructions. Correct installation
of the engine is of the greatest
importance for safe navigation and
protection of the environment.
It also ensure maximum service life
under normal conditions of use.
Engine damage caused by failure
to follow installation instructions is
not covered by the warranty.

OVERVIEW
4
Remote Control
The remote control is an optional
extra not in the scope of supply
of the engine. The remote control
installed on the boat can be different than the ones shown in this
document.
On most boats, the control lever
controls both the engine rpm and
the gear shift (ahead / astern).
However, some boats can be
equipped with a separated shift
command.
It can also be fitted with a neutral
safety switch that prevents the
engine from starting until the lever
is in neutral position.
Consult the boat builder or your
Nanni dealer if you are not sure
about the operation of the remote
control.
Power Take Off
Some engines can be fit with a
Power Take Off system. This system allows to power accessories
like bilge pump, watermaker, etc.
NOTICE: Any mechanical power
taken from the engine from a PTO
reduces the power delivered to the
propeller. The use of a PTO should
always be studied and approved
by the R&D department of Nanni
Industries S.A.S France. Contact
your Nanni dealer for more informations.
Trolling valve
The Trolling valve system allows
to reduce the rotation speed of the
propeller below its speed when the
engine is at idle. The boat speed is
reduced by 30% to 70%.
I CAUTION
The Trolling valve system must
never be used for manoeuvring.
It also must never be used at an
engine speed of more than 1200
rpm.
10
Operation in cold
weather conditions
Nanni engines are designed to operate effectively in cold weather.
However, for effective starting
and cold weather operation, extra
care are necessary. Contact your
Nanni dealer for additional information and local availability of cold
weather aids.
WINTER GRADE FUEL
Winter grade fuel allows to protect
the injection system when temperatures fall below 5°C (40°F). Winter
grade fuel is best suited for cold
weather operation thanks to its
lower cloud and lower pour points.
However, using winter grade fuel
may reduce power and fuel efficiency as winter grade fuel has a lower
BTU (heat content) rating. Check
the grade of fuel being used before
troubleshooting for low power complaints in cold weather operation.
In all cases, fuel quality and fuel
sulfur content must comply with all
existing emissions regulation for the
area in which the engine operates.
Oil viscosity
Use seasonal grade viscosity
engine oil based on the expected
air temperature range between oil
changes.
Follow the diagram below to adapt
the oil viscosity:

Engine homologation
The engine type can be exhaust
emission certified. It means that
Nanni guarantees that all engines
of the same type that are manufactured are approved and certified by
the authorities in accordance with
different exhaust emissions standards.
However, for the engine to be in accordance with this standards, special requirements for maintenance
and service are to be followed:
• Only Nanni replacement parts
must be used.
• Maintenance intervals must be
observed.
• The engine must not be modified
in any way except with accessories and service kits approved by
Nanni Industries S.A.S. France.
• Service of the fuel system must
always be carried out by an authorized Nanni workshop.
• No modifications to the air intake
and exhaust system may be
undertaken.
• Seals may only be broken by
authorized personnel.
• The operation instructions stated
in the relevant manuals should
be follow by the user.
Nanni’s responsibility for the engine
specification being in accordance
with the certification will be invalidate if one or several of this conditions are not followed.
Environmental
responsibility
Nanni designs its engines to have
minimum environmental impact.
This objective, however, can only
be achieved with your full cooperation.
Our operating and maintenance
instructions are to help you to protect your engine and adopt environmentally responsible behaviour.
Ensure you only use the fuels and
oils recommended. Using another type of fuel or oil could cause
major malfunctions, an higher fuel
consumption, a reduced engine
service life, and a greater discharge
of exhaust gases.
When draining the oil and changing
the oil or fuel filter, dispose of the
waste in an appropriate container.
These fluids cause major damage
to flora and fauna if discharged into
nature. Use an absorption kit in the
event of accidental discharge of oil
or fuel into the water.
12
Warranty
This manual is supplemented by
a Warranty Information Booklet.
We recommend that you read this
publication thoroughly.
Pay special attention to the applicable duty cycle and to the limitations that result. Failure to comply
with the warranty conditions will
void the Warranty.
The validity of the Warranty is also
dependent on proper installation
and maintenance operation being
carried out by an authorized Nanni
representative.
NOTICE: Late or improper maintenance or use of spare parts other
than Nanni original spare parts will
invalidate Nanni’s responsibility for
the engine accordance with homologation and will void the Warranty.
Modifications to the engine’s settings, as well as any other technical modification (accessories,
spare parts, additional equipment,
etc) ARE FORBIDDEN WITH-
OUT WRITTEN AUTHORIZATION
FROM NANNI INDUSTRIES S.A.S.
Any modification will void the Warranty. Damage caused by failure
to follow operation instructions or
incorrect operation is also not covered by the warranty.
Commissioning
inspection
Commissioning inspection is a
condition of the validity of the Limited Warranty. Moreover, it allows
the registration of the product at the
factory and record important informations regarding the product.
By registering the product, you will
receive the best warranty coverage
possible and Nanni will be able to
contact you in the event of updates
or service notifications.
Operations to be performed during
commissioning inspection are specified in the Warranty Booklet. The
commissioning inspection must be
signed by the seller and the owner
of the engine.
It’s the owner responsibility to
control that the commissioning
inspection has been fully completed and signed by the person who
carried out the inspection.
The informations regarding the
RPM must be taken using an electronic tachometer. Never use the
tachometer of the instrument panel
for this purpose.
13
About the
propeller
The propeller is a critical component of the propulsion system. It
converts the engine power in thrust.
To be efficient, the propeller must
be perfectly adapted to the boat
and to its use.
In all cases, the propeller should
allow the engine to reach its rated
rpm with the maximum boat load.
A faulty operation of the engine is
often due to an inadequate and / or
damaged propeller.
Behaviour of the
boat
If this is your first boat or if you are
not familiar with the boat, we urge
you to practice controlling the boat
at slow speed as a first step.
Avoid violent manoeuvres or
unexpected speed changes while
sailing. People can fall over or
overboard.
Keep also in mind that the weight
distribution (passengers, equipments, etc.) inside the boat has
an impact on the behaviour of the
boat when cruising. Depending the
position of the load, the behaviour
of the boat may change, particularly
in the case of a planning hull.
The condition of the hull and the
propeller is also a critical factor. A
dirty and / or damaged hull will modify the behaviour of the boat and
therefore the engine performance.
It can also cause cavitation which
can seriously erode the surface of
the propeller, the drive, etc.
