ner. The circuit must be kept upright some minutes to guaranteed that the anti-freeze protection mixture reaches
all ranges of the cooling system.
2. The concentration of the anti-freeze mixture in the internal cooling circuit must be checked with a suitable measu-
ring instrument. The concentration must be furnished according to the lowest temperatures which can be expec-
ted.
3. Clean raw water filter and check seal.
4. Check water cock for practicability. And spray with a corrosion protection oil from the inside or lubricate with aci-
dless grease.
5. Check all hoses and hose connectors for good condition. The rubber hoses are very sensitive to enviromental
influences. They can age fast with dry air, in environment of light oil and fuel steams and increased temperature.
The hoses must be checked regularly for elasticity. There are operating situations, which the hoses must be
renewed once in the year.
6. Check the hose connectors at all raw water valves doubly and if possible protect them with double hose clamps.
7. Dismount the impeller of the cooling water pump and check for wear. The impeller may not remain in the pump. It
must be greased with vaseline and be kept at a dark place. It can be reintragrated in the spring again into the
pump, if it is in good condition. The impeller is a wearing part, it is recommended to renew it always in the spring,
independently how many operating hours the genset ran.
8. Control of the vent valve at the raw water inlet. If the generator is installed below the waterline, always a vent
valve is necessary. The vent valve must be checked also during the season regularly. In the winter storage the
vent valve should always be disassembled, checked and greased. Hardens or got parts dirty are to be replaced.
9. Check water lock: If the generator were rinsed with an anti-freeze mixture, the antifreeze mixture can leave in the
water lock. If the generator were rinsed with fresh water, the water in the water lock must be drained. Otherwise
the danger exists that the collector is blown up and destroyed by ice.
10.Check the exhaust/water separator on leakage and if the hose connectors at the lower surface of the separation
unit are in normal condition. (with extremely sulfureous fuels it is possible that also high-grade steel tube ends
are attacked.)
11. Check all construction units at the generator inside the sound cover for leakages. If there are traces of humidity in
the sound cover, the cover must be dried. Further the cause for the wetness must be surched and eliminated.
12.During the winter storage the upper section of the sound cover must be taken off, in order to avoid condensed
moisture formation, if traces of humidity remain in the sound cover inside casing by leakages in the raw water cir-
cuit.
13.The generator housing and the housing of the engine should be sprayed with a corrosion protection oil before the
winter storage. This procedure is recommended also in the season. This procedure can avoid that arising and
humidity marks on the surface of the aluminum construction units be noticed too late.
14.Disconnect the starter battery (positive and negative pole).
15.Lubricate the spindle for the number of revolutions adjustment device with a special lubricant (Antiseize grease).
16.Check cooling water connection block at the generator housing on traces of corrosion and if necessary renew.
(only such traces are to be considered, which refer to clear "blossoming" of the material. If the surface is only
grey coated, this is only an indication for the fact that aluminum came into contact with condensed moisture.)
17.Use of a air dehumidifier. The best way to protect a yacht in the winter storage against damage by humidity is, to
places a air dehumidifier inside the ship and locks all hatches. The devices have a hygrometer, which switches
the device off, if the humidity is under the adjusted value. There is no better method, in order to protect pads,
cable, electronics, wood, engines etc. optimally against any rotting by humidity.
6.9.2 Initiation at spring
• Before the first start turn the engine once with the hand, in order to eliminate necessary existing corrosion begin-
nings in the bushing. If necessarily carry out normal engine inspection.
• Change engine oil and engine oil filters.
• Reintegrate the impeller of the cooling water pump and check pump for leakage.
• Charge starter battery of the generator, connect cables and check battery voltage.
