7.1.2 Start of propulsion engines

Before starting the new or overhauled propulsion engines for the first time, carefully read the technical documentation supplied by the Manufactures.
During the first operating hours, we recommended that the engines not be run at more than 3/4 of their maximum load; initial run-in should be at variable speeds.
After this initial run-in, the engines can be gradually brought up to full output.
Before starting the propulsion engines, always check that the sea water intake valves of the cooling system are completely open.

Also check that following levels are correct:

Coolant level;
Engine oil level;
Fuel quantity necessary for navigation.

If necessary, fill with coolant mixture, oil and fuel.

CAUTION

Use only technical fluids approved by the Manufacturer, following the instructions provided by the Manufacturer. Engines must always be started with inverters in neutral position and throttle levers set to minimum speed.

Activate and check the correct functioning of the following utilities:

Electronic engine starter key;
Air extractors;
Navigation lights;
Horn;
Electronic set;
VHF.

DANGER

Before starting the engines, ensure that nobody is standing in the dangerous area.

NOTE

The electronic engine start system does not involve actually inserting the keys into the key slot, but simply swiping the key (E-key) on the engine ignition.

Carry out the following operations:

Set the gearbox to neutral position by using the throttle installed in the helm position.
Hold the E-Key in front of the panel, the system unlocks and IGNITION switches ON.
Press and hold the “Start/Stop” button to operate the starter engine.
Do not operate the starting engine for more than 10 consecutive seconds; if the engine has not started yet, release the push-button, wait for about 30 seconds and the operate the starting engine again.
Once the first engine has been started, only after having verified its regular operation, start the second engine too, by following the same procedure described above.
After engines start, verify that the oil pressure rises to normal values within 10 seconds. If low pressure condition persists, immediately stop the engines.

CAUTION

If you are forced to use battery parallel to start engines, it is advisable to disconnect all unnecessary equipment to avoid voltage drops.

Long idle operation may cause cooling of the engine and subsequent bluish or white smoke.
We therefore suggest avoiding long idle operation.
The slow run implies major wear of the engine mechanical parts and is the most harmful from the point of view of polluting exhaust.
