  • 9. MR700 Battery Precautions For Multiple Engines With Electronic ControlAlternators: Alternators are designed to charge a single battery that supplies electricalpower to the individual engine that the alternator is mounted on.Batteries: Boats with multi-engine Electronic Control power packages require each engine to beconnected to its own battery. This assures that the engines Electronic Control Unit (ECU) has astable voltage source.Battery Switches: Battery switches should always be positioned so each engine is running off itsown battery. Do not operate engines with switches in BOTH or ALL position. In anemergency, another engines battery can be used to start an engine with a dead battery.Generators: The generators battery should be considered in the same manner as anotherengines battery.ENGLISH - 28/58- SYSTEMS INSTALLATIONTHE PRESENT DOCUMENT IS PROPERTY OF VM MOTORI S.P.A.; IT IS PROTECTED ACCORDING TO THE LAWS IN FORCE ON COPYRIGHT AND INDUSTRIALPROPERTY; ITS REPRODUCTION, ITS DELIVERY TO A THIRD PARTY OR ANYWAY ITS CIRCULATION IS NOT ALLOWED WITHOUT PREVIOUS WRITTEN CONSENT OFVM MOTORI S.P.A.; OFFENDERS WILL BE PROSECUTED ACCORDING TO THE LAWS.

  • 12. MR700 FUEL SYSTEMGeneralThe installation of the fuel system components: fuel tanks, shut-off valves, fuel line, filtersand extra filters, etc., must be carried out carefully to ensure sufficient supply of fuel to theengine as well as to fulfil the requirements of perfect sealing and protection against fire.Carefully plan the location of the tank before beginning work. Use good quality shutoffvalves to prevent the fuel from dripping. A fuel system that always drips implies a great riskof operation.The shutoff valves must be located preferably outside the engine room or must becontrolled from a remote position.The amount of fuel can be subdivided between several tanks to maintain the center ofgravity as low as possible and also to give the hull certain possibilities of longitudinalstability.If the tanks are structural, then sufficient ventilation must be provided to the surroundingspace. The local legislation can apply more strictly all the prescriptions recommended and published in the literature of the engine manufacturers.Make sure that the high pressure pipes between the injector pump and the injectors arenot bent and are not stopped on the engine because there is a risk of bending the highpressure pipes.Do not put anything under the high pressure pipes, and keep the original seals intact.Otherwise, there will be a risk of breaking the pressure lines and of causing fire.When working on the fuel system, it is important to keep it free from dirt.The installer has to connect the fuel circuit inlet and prepare a fuel supply system incompliance with the data reported in chapter “Installation data”.The following diagram illustrates the fuel high pressure (red) and low pressure (blue)circuits.The interconnecting point to which the installer has to connect the fuel supply is indicatedas fuel inlet.ENGLISH - 31/58- SYSTEMS INSTALLATIONTHE PRESENT DOCUMENT IS PROPERTY OF VM MOTORI S.P.A.; IT IS PROTECTED ACCORDING TO THE LAWS IN FORCE ON COPYRIGHT AND INDUSTRIALPROPERTY; ITS REPRODUCTION, ITS DELIVERY TO A THIRD PARTY OR ANYWAY ITS CIRCULATION IS NOT ALLOWED WITHOUT PREVIOUS WRITTEN CONSENT OFVM MOTORI S.P.A.; OFFENDERS WILL BE PROSECUTED ACCORDING TO THE LAWS.

  • 15. MR700 Fuel tankIf possible, fuel tank have to be located on the same level or someway above the engine. Ifit is installed in a lower position, then due attention must be paid to the maximum suctionhead of the high pressure fuel pump, that must not exceed -250 mbar.Note that the suction head must be calculated from the bottom end of the suction piping.The fuel return piping must be installed submerged approximately 10 mm over the bottomof the tank and distant from the suction pipe to prevent air from entering when the engineis turned off.If the tank is located under the level allowed by the suction head of the pump, then the fuelhas to be delivered into a tank by means of a pump. Flexible connectionsAll pipes from and to the propulsion unit must be fitted with flexible connecting elements.These flexible connecting elements are available in the VM scope of supply and theirpurpose is to compensate for relative motions between the propulsion plant and theonboard piping systems. If the hoses, bellows or rubber sleeves are not supplied by VM,they must satisfy the minimum requirements for plant operation. If doubt arises, customersshould consult VM to ascertain the displacements occurring at the interfaces due tomovements of the resilient mounts and thermally induced expansion. The invariable rule isthat all flexible connecting elements must be connected directly with the on-engineinterface.Notes on installation:The installation characteristics for the hoses, bellows and rubber sleeves are stated in thechapter installation data.If welding is performed on the on-board piping system, it is important ensure that nohoses, rubber bellows or rubber sleeves are installed in the line, as they could bedamaged by the welding operations. If already installed, these elements must be removedfor the duration of the welding operations and stored where they are safe from damagesuch as could be caused by weld spatter, e.g.ENGLISH - 34/58- SYSTEMS INSTALLATIONTHE PRESENT DOCUMENT IS PROPERTY OF VM MOTORI S.P.A.; IT IS PROTECTED ACCORDING TO THE LAWS IN FORCE ON COPYRIGHT AND INDUSTRIALPROPERTY; ITS REPRODUCTION, ITS DELIVERY TO A THIRD PARTY OR ANYWAY ITS CIRCULATION IS NOT ALLOWED WITHOUT PREVIOUS WRITTEN CONSENT OFVM MOTORI S.P.A.; OFFENDERS WILL BE PROSECUTED ACCORDING TO THE LAWS.

  • 16. MR700General notes on system routing:• Hoses must be installed such that they are not subjected to tensile or compressive loads in operation.• Hoses should follow the contour of the foundation as closely as allowed by the specified minimum bending radii.• Multiple hoses should always be routed together and kept parallel.• Suitable fittings (e.g. pipe elbows) can be used to avoid additional stresses and strain on the hoses.• When installing hoses, care must be taken to ensure that the hoses are not twisted.• For a curved run, the length of the hose must be such that the curve does not commence less than approx. 1.5 d from the fitting.• Flexible connecting elements should be arranged and/or secured in such a way as to prevent exposure to external mechanical influences, for example rubbing.• The attachments used to secure hoses must be of correct size for the hose diameters.• Hose attachments should not be used at points where they would impede the natural freedom of motion of the hose.• High ambient temperatures significantly reduce the durability of flexible connecting elements and may even lead to failure of the component. Always ensure adequate clearance from components that radiate heat or provide suitable heat shielding.Make sure to use the inner diameter size correct for the hose.Secure the fuel line with clamps. The classification societies and some registration authorities (that is to say, river authorities) do not allow rubber hoses for fuel lines, or prescribe hoses with concrete specifications. check in case the boat were used in these zones.ENGLISH - 35/58- SYSTEMS INSTALLATIONTHE PRESENT DOCUMENT IS PROPERTY OF VM MOTORI S.P.A.; IT IS PROTECTED ACCORDING TO THE LAWS IN FORCE ON COPYRIGHT AND INDUSTRIALPROPERTY; ITS REPRODUCTION, ITS DELIVERY TO A THIRD PARTY OR ANYWAY ITS CIRCULATION IS NOT ALLOWED WITHOUT PREVIOUS WRITTEN CONSENT OFVM MOTORI S.P.A.; OFFENDERS WILL BE PROSECUTED ACCORDING TO THE LAWS.

  • 17. MR700 Fuel pre-filtersThe use of fuel pre-filter/water separator is mandatory.The pre-filter has to be installed in the suction side, between the fuel inlet and the fuel tank,and must be positioned at a height between the tank base and the suction pump, toreduce resistance in the supply pipe.Install the filter vertically in a support on a bulkhead, in a position not affected by enginevibration and protected as much as possible from fire in the engine room.The filter location must be easily accessible for inspection and replacement of the filterelements.Fire-resistant material in fuel filters is prescribed for classified installations and in somecases by local authorities.Three progressive levels of filtration are recommended: water separation, coagulation andfiltration ensure that fuel reaches the engine free of contamination.Water and other impurities are collected in bottom containers, from where they can bedrained by means of a drain valve. Maximum suction head to high pressure fuel pump must below 250 mbar at any running conditionENGLISH - 36/58- SYSTEMS INSTALLATIONTHE PRESENT DOCUMENT IS PROPERTY OF VM MOTORI S.P.A.; IT IS PROTECTED ACCORDING TO THE LAWS IN FORCE ON COPYRIGHT AND INDUSTRIALPROPERTY; ITS REPRODUCTION, ITS DELIVERY TO A THIRD PARTY OR ANYWAY ITS CIRCULATION IS NOT ALLOWED WITHOUT PREVIOUS WRITTEN CONSENT OFVM MOTORI S.P.A.; OFFENDERS WILL BE PROSECUTED ACCORDING TO THE LAWS.

  • 18. MR700 SEA WATER COOLING SYSTEMSA standard characteristic of diesel engines made by VM Motori S.p.A is a closed coolingsystem, with fresh water circulating through the cooling circuits and the heat exchanger ofthe engine. In the heat exchanger, the engine coolant is cooled by sea water.In order to reduce corrosion to a minimum, the correct combinations of materials must beused for pipes, valves etc.Electrolytic corrosion can result when two different materials are connected via water orhumidity inside metal surfaces.ENGLISH - 37/58- SYSTEMS INSTALLATIONTHE PRESENT DOCUMENT IS PROPERTY OF VM MOTORI S.P.A.; IT IS PROTECTED ACCORDING TO THE LAWS IN FORCE ON COPYRIGHT AND INDUSTRIALPROPERTY; ITS REPRODUCTION, ITS DELIVERY TO A THIRD PARTY OR ANYWAY ITS CIRCULATION IS NOT ALLOWED WITHOUT PREVIOUS WRITTEN CONSENT OFVM MOTORI S.P.A.; OFFENDERS WILL BE PROSECUTED ACCORDING TO THE LAWS.

  • 19. MR700 Sea water cooling circuitSea water is circulated through the system by the rubber impeller of the water pump.The pump is mounted in the engine and is impelled via belt.The water intake must be positioned so that the water line to the pump be as short aspossible. In addition, it must be positioned so that no air can be dragged into the systemwhen the boat is planing or rolling in the sea. Sea water pump Sea water pump connection ENGINE TYPE MR704 Before connecting the MR704 Engine with the sea water pump, remove the yellow protective cap. Sea water pump connection Sea water pump ENGINE TYPE MR706The water intake, the valve and filter must have a flow area sufficient to prevent volumerestrictions. For planing boats, fluted water intakes are recommended.ENGLISH - 38/58- SYSTEMS INSTALLATIONTHE PRESENT DOCUMENT IS PROPERTY OF VM MOTORI S.P.A.; IT IS PROTECTED ACCORDING TO THE LAWS IN FORCE ON COPYRIGHT AND INDUSTRIALPROPERTY; ITS REPRODUCTION, ITS DELIVERY TO A THIRD PARTY OR ANYWAY ITS CIRCULATION IS NOT ALLOWED WITHOUT PREVIOUS WRITTEN CONSENT OFVM MOTORI S.P.A.; OFFENDERS WILL BE PROSECUTED ACCORDING TO THE LAWS.

  • 20. MR700In very contaminated water and in presence of sand and mud in the water, these elementsare dragged into the water pump; this will reduce the useful life of the pump and theimpeller.Fouling and obstructions of the sea water cooling system contribute to reduce theperformance of the cooling system and to cause damage to the engine.A sea water filter helps extend the life of the pump and reduces fouling of the heatexchanger, of the oil cooler and after cooler.The following pressure conditions must be fulfilled:• The pressure in the suction side of the pump (PA), measured immediately upstream of the pump, with the engine running at maximum rpm and at the cruise speed, must be between 0 and –200 mbar (NPSHr = 10 m H2O )• The differential pressure between the suction side of the pump and the pressure side does not have to exceed 1.7 bar.• The sea water inlet, the valve, the filter hoses and the pipes must have a flow area sufficient to prevent unnecessary pressure drops. To prevent pressure drops, any bend in the line must be avoided. We recommend the use of copper pipes. If a bend is installed to reduce tensions, it must be connected with a reinforced rubber hose. In order to prevent breakage, the hose must have several layers.• The increased temperature of the sea water and the pressure give a good understanding of the function of the system.• When an original sea water pump supplied by VM Motori S.p.A is replaced with a different type of pump, the flow must be measured.The following scheme shows the main component parts of this system, the circulatingdirection of the various fluids and the interconnections for closing the sea water circuit.The installer has to prepare the interconnection with itmes 1 and 9-10, taking into accountthe data provided in charter “Installation data”.ENGLISH - 39/58- SYSTEMS INSTALLATIONTHE PRESENT DOCUMENT IS PROPERTY OF VM MOTORI S.P.A.; IT IS PROTECTED ACCORDING TO THE LAWS IN FORCE ON COPYRIGHT AND INDUSTRIALPROPERTY; ITS REPRODUCTION, ITS DELIVERY TO A THIRD PARTY OR ANYWAY ITS CIRCULATION IS NOT ALLOWED WITHOUT PREVIOUS WRITTEN CONSENT OFVM MOTORI S.P.A.; OFFENDERS WILL BE PROSECUTED ACCORDING TO THE LAWS.

  • 24. MR700 Exhaust lineVM engines are supplied with a “wet exhaust line”.The expression " wet exhaust line " implies that cooling water enters the exhaust forpurposes of refrigeration and sound absorption.A wet exhaust line is particularly advisable for use with flexible mount engines and can bemade of oil and heat resistant rubber. Also, it would be the most comfortable noisereduction system.Normally, manufacturers of marine engines do not commercialize complete wet exhaustsystems. OEM, shipyards, and boat builders, select the components and experiment thefinal exhaust system that complies with all requirements of the suppliers.
