For the cooling of the engines is used sea water that is sucked directly from the internal pumps of the engines. The sucked water, after passing through the filters, is sent to the engines, then to the inverters and finally discharged into the sea. In the event of flooding of the engine room you can use this system to pump water from the bilge in large quantities proceeding as described in “emergency bilge suction engines”.
When the bilge is nearly dry, remember to turn the valves back to sea water intake position, in order to avoid engine damages.
Before opening the sea cock strainer for cleaning, remember to close the cut-off valve in the hull.
If the yacht is not used, close as a precaution, all cut-off valves of the sea cocks; as soon as the yacht is reused, remember to open them.
