8.10 ENGINE COOLING SYSTEM
The engine cooling uid is sea water circulated by the engine inner pumps,
by means of special water intake.
The sucked water ows through the strainers, is delivered to the engines,
gearboxes, heat exchangers and is nally drained overboard.
In case of engine room ooding, it is possible to use this system to suck
water from the bilge in large quantity proceeding as indicated at paragraph
“Engines suction with bilge emergency”.
When required, turn the valves completely and never to intermediate posi-
tions.
CAUTION
When the bilge is nearly dry, remember to turn the valves back to sea
water intake position, in order to avoid engine damages.
WARNING
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.
