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.
4.
Renew and refill the heat exchanger to the maximum level with a mixture of fresh water and
anti-freezing agent.
5.
Renew the oil in the engine.
6.
Cover the air intake.
7.
If the fuel tank is small, empty it completely and clean it; fill it up again with a mixture of
diesel and anti-corrosion additive. Solé S.A. recommends DIECYL PLUS. Add one measure of
this additive for every 25 liters of diesel. On the other hand, if the fuel tank is large, add 1
liter of this additive for every 500 liters of diesel.
8.
Clean and dry the area where the engine is installed.
9.
Loosen the belts.
10.
Apply dielectric spray on the electrical connection, disassemble the battery and charge it
several times during the time it is not being used.
11.
Apply moisture repellent spray on the motor.
4.6.
Maintenance during the storage
During the long engine storage, it has to be stored inside a ventilated area and free of
humidity.
When the engine stay stopped for 3 months or more, inside parts can be oxidize and lost the
oil film. As a result, the engine could to size up after the storage. To avoid this, the engine must work
periodically during the storage.
Realize the following steps at least once per month:
1.
In case that has a battery next to the engine, check the electrolyte level and fill it.
2.
Start the engine during approximately 10 seconds.
3.
Stop the engine during 1 minute. Repeat this action two or three times.
4.
Be sure that oil pressure of the engine increase.
5.
Get the engine work during 5 or 10 minutes without load, as maintenance operation.
4.7.
Restoration of operational conditions
When starting up the engine again after winter lay-up, certain operations must be
performed. Follow these steps:
1.
Fill the fuel tank with clean diesel. The mixture of diesel oil and anti-corrosion additive in
tank for winter lay-up can be used to operate the engine.
2.
Check the fuel filter. If the filter is clogged, replace the filter.
3.
Renew the oil in the engine.
4.
Check the condition of coolant circuit’s rubber hoses.
5.
Reconnect the battery and apply a layer of neutral Vaseline to the battery terminals.
6.
Remove the nozzle supports and clean them. If possible, verify the setting of the nozzles
at a workshop. Then install the clean nozzles.
7.
Connect the cooling and exhaust system. Open the seawater cock.
8.
Verify whether there are any leaks in the fuel, coolant and oil systems.
