4.3 Genset Operation at Low Temperatures
Whenever the atmospheric temperature drops below zero, the following series of
circumstances occur:
The cooling liquids may freeze.
The oil becomes thicker.
There is a drop in the voltage at the battery terminals.
The inlet air temperature is low and the genset has difficulty in starting.
The fuel loses fluidity.
To prevent the damage caused by low temperature operation, the genset should be prepared:
1.
Use special low temperature coolant or suitable anti-freezing agent concentration.
2.
Close the seawater cock, when the genset is stopped. Open the seawater filter cover and
start the genset adding a mixture of freshwater and suitable anti-freezing agent
concentration (see package labels) until the seawater circuit is filled completely. Stop the
genset and replace the seawater filter cover. Before starting the genset again, open the
seawater cock.
Repeat this operation whenever the genset is used at temperatures below 0ºC.
3.
Use oil with suitable quality and viscosity. SAE 15W40 is recommended.
4.
Cover battery with an adequate material to protect it against the cold. Check that the
battery is fully charged.
It is also advisable to use a dielectric spray on the electrical connections.
5.
When starting the genset, make sure that the glow plugs become hot enough.
6.
If necessary, replace the diesel oil by a specified diesel oil type for low temperatures. The
accumulation of impurities in the fuel tank could cause faulty firing.
NOTICE
All gensets not in use are subject to rusting and corrosion of machined surfaces that are not
protected with a paint coating. The degree of corrosion depends on meteorological changes and climatic
conditions. The following recommendations are therefore of a general nature but they will help prevent
or reduce the risk of damage due to rusting.
4.4 Winterization and Preservation
If the boat is not going to be used for a long period of time or during the winter, certain tasks
must be carried out to keep it in perfect operating condition. Follow the steps indicated below carefully:
1.
Clean the outer surface of the engine.
2.
Bleed the seawater circuit by filling it with fresh water. Fill the seawater circuit again with a
mixture of fresh water and anti-freezing agent.
3.
Remove the impeller from the seawater pump, clean it with fresh water and store it in
place protected from moisture and sunlight.
