1 Preface
The reliability of the total propulsion unit is dependent on the quality of the installation.
Nearly all the problems are caused by faults or inaccuracies which occur during the installation. It is
most important therefore to follow during installation the recommendations mentioned in this manual.
1.1 Engine ID Plates
The ID labels are placed on the engine as shown in the pictures below:
The engine number is marked on the engine where indicated in the picture below:

1.2 Engine storage, before use
If the engine is stored for a prolonged period, check the possible conditions of conservation in relation to the
storage environment and the type of packaging.
The engine is supplied with a protection treatment which is valid for 6 months from delivery date.
1 Check for the coolant (coolant circuit). The engine supplied with a mixture to withstand storage temperature
of -15 °C (5 °F).
2 Attention: The raw water circuit could contain engine test bed water. Drain completely the raw water
circuit if the storage temperature is lower than 0°C (32°F).
3 Grease the turbocharger operating mechanism after this period.
4 Verify the packages integrity.
5 Humidity and salt corrosion could damages the engines during their storage.
1.3 First engine start
1 Read the owner’s manual.
2 Verify the fuel feed line for possible leaks. Take care to avoid restrictions in the fuel line pipes.
3 Verify and if required grease all the couplings, the turbocharger operating mechanism.
4 Check and verify the electrical connections. Important: Wrong connection of positive and negative could
provoke short circuit and damage the engine.
5 Check the battery condition and state of charge.
6 Check the raw water circuit, the connection and open the sea cock.
7 Check the belt and belt tensioner.
8 Check coolant level and oil levels of both engine and gearbox, verify if fuel is available in the tank. Fuel tank
must be clean!
9 Turn ON the red button on the ECU box and verify that the fuse LED’s light-up.
10 Verify the position of the control lever and make sure it is in Neutral position.
11 Verify the gearbox – stern drive oil level.

400202.01 5
vetus®Installation manual VF4 VF5
12 Make engine diagnosis. Important: Compile and send the installation form data request.
13 Verify the engine – propulsion alignment, grease the mechanical connections.
14 Start the engine, lets warm up the engine for few minutes at minimum RPM idle.
15 Verify for any leaks, verify the sea water pump, and verify the flush of water on exhaust system, verify that all
warning lights on the instrument panel are OFF and no alarm buzzer sounds and verify if oil pressure – water
temperature and charge current are OK *.
Important: If you hear a strange noise, or vibration of the engine is extreme or black smoke is
coming out of the exhaust stop the engine immediately and ask for assistance.
When the temperature of the engine stabilizes at a temperature higher than normal it might be neces-
sary to bleed the coolant circuit.
Bleeding the coolant circuit:
• Opentheexpansiontankcaptolettheairescape.
• IncreasetheRPMto2000anddecreasefewtimeswithoutengagingthegearbox.
• Addwatertothecoolantcircuitifnecessary.
• Closethecap.
• Verifytheenginecoolanttemperatureagain.
16 Take the command on the levers.
17 Never exceed the first time 3/4 of maximum rpm.
18 Verify all person are on board and engage the gear to test the gearbox – stern drive and carry bout the sea
trial.

1.4 Long engine storage – Inactivity
If the engine remains inactive for a period of time exceeding 6 months, you need to protect it from oxidation and
breakdowns in accordance with the following instructions:
1 Let the engine run for 15 minutes at 800 rpm; stop the engine and drain the oil.
2 Put oil (according to the specifications MIL-60B-type 2) into the oil sump until the oil sump reaches at least
‘Min’ on the oil dipstick.
3 After emptying the fuel filters, disconnect the pipes of the feeding of the injection system at the top of the
feeding pump, and connect it with the proper tank containing oil CFB (ISO 4113).
4 Let the engine run for 15 min. at 800 rpm; then, by using an oil gun, slowly atomize (nebulize) for about one
minute 60 grams of oil MIL-60B-type-2 into the intake manifold.
5 Disconnect the pipes of the feeding of the injection system from the tank containing the oil CFB and re-
connect it to the fuel tank.
6 Seal with tape, on both the engine and exhaust pipe, the access lights, aeration lights and breather pipe
lights.
7 Put a very visible paper on the engine where it is clearly stated that the engine is ‘WITHOUT OIL’.
8 Disconnect the batteries and put them in a dry place, always making sure that they are charged.
9 Drain the cooling water in case it does not have anti-freezing liquid or anti-corrosion liquid
10 If the engine is connected with the propulsion system verify for the oil level.
11 Clean the engine from salt and eventual rust. Paint rusted parts. Spray the engine with CRC 6-66 marine
lubricant spray to avoid corrosion.
After a period of inactivity, it is necessary to carry out a some maintenance work before starting the
engine again to ensure its efficiency conditions.
1 Check the battery charge level conditions. Assure that the battery voltage is over 12.5 V.
2 Make sure the electric contacts are intact. Assure the correct electrical connections.
3 Carry out the engine diagnosis.
4 Check the oil level-conditions, and if necessary, top- up or replace.
5 Verify and if necessary replace the oil filter.
6 Check the coolant level an mixture, and if necessary top – up.
7 Replace / Clean the fuel filter.
8 Clean the air filter.
9 Verify the belts status and tighteners.
10 Verify the integrity of the sea water pump impeller.

400202.01 7
vetus®Installation manual VF4 VF5
11 Check the integrity of electrolytic zincs.
12 Verify and if is necessary grease: starter pinion, turbocharger leverages mechanical propulsion couplings.
13 Start the engine and run at minimum speed for few minutes.
14 If no anomalies bring the engine to its operating temperature, 70 - 80 °C (158 - 176 °F). Verify that there is
no air in the coolant circuit – bleed the air from coolant circuit if necessary.
15 Turn off the engine and check again the engine oil level and coolant level.
16 Verify for tightening.

2.4 Tightening torque
Tightening torque for vital connections, which should be tightened with a torque wrench are indicated in the
pictures.
The torque readings refer to lightly oiled or dry thread, screw heads and mating surfaces. For connections
where special torque denotations are not indicated, the general tightening torque is applicable according to the
table below. The torque readings are guide values, and connections do not need to be tightened with a torque
wrench.
The screws and nuts divided into different class. It is therefore important when a screw connection is dismantled
to return the screw to their original positions. The table refer to 8.8 class screws.

2.5 Operation / duty cycle
With respect to operation and duty cycle VF4 and VF5 diesel engines are rated for
PLEASURE CRAFT DUTY ONLY!
Maximum RPM:
Model Max. RPM (under load)
VF4 series 4000
VF5 series 4200
Wide open throttle operation is limited to short periods of time.
Important: Damage caused by improper application or failure to operate within the operational
capability or duty cycle, will not be covered by the Vetus Warranty.
2.6 Engine bed
The engine bed should have sufficient stiffness and strength: it must be bonded or connected over its total
length to the bottom of the boat and in addition must have sufficient transverse reinforcement either by its own
method of construction or alternatively by the use of straightening ribs.
An engine which is easily accessible will be inexpensive to work on is terms of both time and money, for example
the water pump situated on the rear side required a sufficient distance from bulkheads.
It is particularly important that both sides of the engine are easily accessible.
The engine inclination should never exceed 15° backwards.
