IVECO Anchoring
If anchoring is accomplished by interposing shock mounts,they must be able to support the engine’s mass and the longitudinal 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 design 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 sufficiently rigid not to create choked areas caused by crushing (1).
IVECO 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.

IVECO Exhaust gas discharge
The exhaust gas discharge conduit 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 pipelines, which is the Yard’s responsibility.
IVECO Electric - electronic equipment
Provide a suitable arrangement of the engine control electronic unit, of the relay box and of the possible optional electronic units, referring to the dimensions and position of the wire harnesses and their connectors.
Both units must be anchored in such a way as to dampen the vibrations and stresses undergone by the hull while underway and/or induced by the engine’s operation.
