To obtain the best engine performance, it is essential not to
deviate from the mission profile for which it was produced
and set up.The engine must not be used for purposes other
than those stated by the manufacturer. IVECO MOTORS is
willing to examine any need for particular installations befo-
rehand. Use of an electronically controlled injection system,
in providing the engine with performance benefits, requires
that the installer and maintenance specialist comply with
some fundamental rules, which will become more and more
commonplace as use of such equipment becomes progressi-
vely more widespread. Boat outfitters and maintenance spe-
cialists are invited to closely follow the instructions contained
herein. No modifications to the engine, its accessories and
components, are allowed.
Failure to comply with the instructions that follow shall
void the warranty and relieve IVECO MOTORS of all
liabilities.
For personnel safety
Specialists and installers are cautioned to comply with
workplace safety rules and to adopt prescribed individual
protection devices when working.
oDrain the cooling, lubrication and fuel lines only after
the fluids have duly cooled. The pressurized cap of the
coolant line may be opened only after the engine has
duly cooled.
oBatteries contain a highly corrosive sulphuric acid solu-
tion: must never be upset and must be handled with
the utmost caution to prevent spillage. Ensure that the
battery compartment is adequately ventilated.
Handling
The engine must be handled by experienced personnel,
using the prescribed tool or a rocker arm that keeps the
lifting lines parallel and with adequate equipment in terms
of capacity and size.The two eyebolts provided for lifting the
engine alone must always be used simultaneously.
Installation
oKnife switches or battery breakers may be used on the
power supply line of the engine electronic unit, provided
they are not used to shut off the engine.
oDo not modify the wiring harnesses; their length may
not be modified: use only available extensions.
oDo not use electronic device wiring harnesses not com-
pliant with the IVECO MOTORS directive, in terms of
length, type of conductor, location, clamping, connection
of the shielding and earth braids.
oTo avoid any interference, the wiring harnesses of the
different on-board electronic devices must follow diffe-
rent paths from those of the engine electronic systems.
oDo not connect any extraneous user device to the engi-
ne electrical equipment.
oDo not energize the on-board electrical system of the
boat without first verifying that there are no short cir-
cuits.
oDo not branch pipes off to draw fuel from the engine
supply lines.
oDo not make any change to the engine’s hydraulic circui-
ts and components.
oDo not execute arc welding operations before removing
the electronic units from their seating, placing them at an
adequate safety distance.
oDo not subject electronic units to temperatures excee-
ding 80°C.
oDo not paint electrical components and their connec-
tions.
oDo not alter the data contained in the engine control
electronic unit.
oComply with prescribed procedures and torque values
when tightening threaded elements.
Start-up
oReady the engine following the procedure set out in
Chapter 14.
oWhen starting the engine the first time, have suitable
means available to cut off air intake in case of a runaway
condition.
oStart the engine after ensuring that it is complete with
every part specified by the manufacturer and required
by the installation, without attempting to start it with
caps and occlusions to the lubrication, cooling and fuel
feed lines.
oCheck that the fluid lines are perfectly sealed, especially
lines for fuels and lubricants, which may cause fires and
consequent harm to persons and equipment.
oMake sure that the various pipelines are not in contact
with warm surfaces or moving parts.
oThe installing yard is required to carry out tests to
verify the functional compatibility between the electri-
cal-electronic equipment of the engine and the other
electronic equipment present on the boat.
Tests and tuning up
oNever disconnect the batteries when the engine is run-
ning.
oRemove the electrical connections from the batteries
before any operation on the electrical system.
oEnsure that the battery terminals comply with the exact
polarity, are properly tightened and protected against
accidental short circuits and corrosion phenomena.

4. GENERAL INSTALLATION CRITERIA
Accessibility
The engine must be located in such a way as to allow filling
and draining engine liquids when doing servicing operations.
Moreover, the relay box and the diagnostic push-button
present on it must be accessible, also when underway.
Anchoring
If anchoring is accomplished by interposing shock mounts,
they must be able to support the engine’s mass and the lon-
gitudinal thrust exerted by the propeller shaft in motion.
If rigid mounting is adopted, particular care must be given to
support alignment and co-planarity.
Information on dimensions and fastening values are provided
in the “Installation Diagram”.
Combustion and ventilation air
Compliance with prescriptions on the quantity of air
required for combustion and ventilation assures a regular
operation of the engine even in adverse conditions and it
enables to deliver its maximum rated power (1).
Sea water line
It must be provided with an intake capable of preventing
the entry of foreign bodies into the suction pipes. Between
the intake and the pump, it is best to interpose a gate to be
closed in emergencies or for extended idle periods and a
filter to stop the smaller impurities; it is also recommended
to install a suitably dimensioned and easily replaced zinc
anode.
The engine sea water line was provided by the manufacturer
with protection anodes to be replaced periodically.
The rubber hoses positioned along the pipeline shall be suffi-
ciently rigid not to create choked areas caused by crushing (1).
Engine pre-heating
If the engine usage profile requires immediate delivery of
power at the highest rpm’s, it is recommended to install an
auxiliary pre-heater on the closed cooling loop.
Exhaust gas outlet
The exhaust gas outlet conduits shall be compliant with the
guidelines contained in the IVECO MOTORS publication
“Guide to the installation of marine engines”; it also provides
indications to compute the dimensions of the exhaust pipe-
lines, which is the Yard’s responsibility.
Electric - electronic equipment
Provide a suitable arrangement of the relay box, and of the
optional electronic unit referring to the dimensions and posi-
tion of the wire harnesses and the relative connectors.
Both units must be anchored in such a way as to dampen the
vibrations and stresses undergone by the hull while under-
way and/or induced by the engine’s operation.
NOTE: Information about optional equipment are described
in the Chapter 21.
(1) The EDC engine electronic control is programmed to
reduce maximum deliverable power if the operating
parameters measured by the sensors show that criti-
cal conditions have been reached, and if exceeded the
engine could be damaged.

7. FUEL LINE
Figure 7
For the installation, the following connections are required:
- from the tank to the prefilter
- from the prefilter to fitting to engine inlet
- from engine outlet fitting to the tank recirculation
Prefilter
The prefilter with priming pump, supplied separately from
the engine, must be fastened near the tank, in a relatively low
point of the line to allow for easy replacement the filtering
cartridge and/or the operation of the hand pump. Avoid the
use of additional mesh or paper filters along the feed lines
between prefilter and engine. To avoid introducing impuri-
ties in the feeding lines inside the engine, do not place filter
cartridges pre-filled with fuel in the system.
Materials Characteristics
The fuel tank and the suction and return assembly must
withstand the continuous abrasion caused by a flow of fuel
oil of 250 l/h at a temperature of 90°C without noticeable
deformation or wear or release of material. Use of metal
tanks, preferably made of iron alloys, is allowed, provided
they are connected to the negative terminal of the battery
to prevent the accumulation of electrostatic charges.
Tanks must be provided with vents to avoid exceeding an
internal pressure of ± 5kPa (± 0.5 m of H2O column); their
shape and the suction assembly must be such as to assure a
suction at the maximum longitudinal and transverse inclina-
tion allowed for the boat, with a residual quantity of fuel oil
considered “reserve”.
The suction inlet should be positioned in such a way as to
avoid taking in sludge.The return flow must be in such a way
as to facilitate the mixing of the returning fuel with the fuel
in the tank. If the tank is lower than the filter, then the return
pipe must always be submerged.The pipes and union fittings
of the fuel line must withstand a fuel oil flow rate of 250
l/h at a temperature of 90°C and a pressure of 3 bar (300
kPa) without noticeable deformation, wear or release of
material. Metal tubes, preferably made of iron alloys, are rec-
ommended, taking care to connect each individual segment
to engine ground to avoid the accumulation of electrostatic
charges and inserting a vibration damper elastic joint on each
segment. The pipes used must be certified according to the
relevant Countries’ rules or to the standards issued by clas-
sification Bodies.

8. ELECTRICAL EQUIPMENT
Figure 10
The electrical equipment of the engine comprises a series of
components provided separately from the engine to enable
an easy and diversified installation, according to the Yard’s
design choices.The need to make accessible, at sea or under-
way, the controls to the electrical components and to the
connector for diagnostics contained in the relay box may be
met through different installation arrangements.
Along with the coupling of all connectors provided in the
wire harnesses, completing the installation also requires the
connecting wire harness (12) for the sensor to detect the
presence of water in fuel (5), to complete the power line and
to connect the accumulator to the engine wire harness.
The connection of the J3 connector enables the electric
connection of the control module to the lubricating oil
pouring pump.
The JC connector is set for the connection to the emergency
stop button.

Power supply line
The power network must be carried out in order to avoid
using both the structure of engine and the structure of the
hull (if this is metallic). For this purpose the electrical starter
motor and the alternator required for this equipment are
characterized by the presence of the terminals for electrical
connections both with the positive and with the negative
pole of the battery.
1. Alternator - 2. Electrical starter motor - 3. Battery -
4. Engine wire harness.
The power supply line, to be built by the yard, comprises:
oA. Connection between the negative pole of the battery
and the terminal “–B” of the electric starter motor
realized with a conductor having a cross section of at
least 95 mm2;
oB. Connection between the positive pole of the batte-
ry and the terminal “30” of the electrical starter motor
realized with a conductor having a cross section of at
least 50 mm2;
oC. Connection between the “30” terminal of the alter-
nator to the positive “+B” terminal of the electric starter
motor, to close the power supply and recharge circuit
of the battery realized with a conductor having a cross
section of at least 50 mm2.
oD. Connection between the “−B” terminal of the alter-
nator to the positive “−B” terminal of the electric starter
motor, to close the power supply and recharge circuit
of the battery realized with a conductor having a cross
section of at least 50 mm2.
The connection of the electric equipment of the engine to
the battery has to be carried out via the two eyed terminals,
“+B” and “–B”, present on the wiring harness.

CAUTION
If magneto-thermal protecting breakers are installed on
the wiring lines of the engine control system, they must
not be used to stop the engine and in any case they must
be activated only a few seconds after shut-off.
