Sea water drawn from under the bottom of the boat is the
mean by which the engine heat, not transformed into
mechanical work, is eliminated.
The water, intaken by the pump set into rotation by the
cranckshaft, by means of a toothed wheel transmission, is
directly sent to the supercharging heat exchanger (after-
cooler), where the water temperature is reduced to improve
engine volumetric efficiency and thus its performance; the
water from the after-cooler, going through the gear box oil
heat exchanger (if fitted), reaches the “sea water / fresh
water” heat exchanger removing the heat yielded by the
engine and conveyed by coolant; temperature control is car-
ried out by the thermostatic valve.
The water, before being let into the sea drainage duct, laps
onto and cools down the “riser”, exhaust gas outlet, where
comes out of the boat with the latter.
