Abstract
Viene descritto nella presente un motore fuoribordo che comprende un motore a combustione interna includente una superficie inferiore che ha in essa una luce di evacuazione di. gas di scarico, una carcassa per albero motore avente una estremità superiore che include una faccia superiore fissata alla superficie inferiore del. motore a combustione interna, una superficie esterna che si estende verso il basso dalla faccia superiore, un passaggio principale interno dei gas di scarico estendentesi verticalmente che si estende dalla faccia superiore e comunica con la luce di evacuazione dei gas di. scarico, un passaggio di evacuazione dei gas di scarico nel funzionamento al minimo incassato nella faccia superiore ed in una relazione distanziata rispetto al passaggio principale dei gas di scarico, e chiuso dalla superficie inferiore del motore a combustione interna, ed una luce di uscita dei gas di scarico nel funzionamento al minimo situata nella superficie esterna e in comunicazione con il passaggio di evacuazione dei gas di scarico nel funzionamento al minimo, ed un tubo evacuazione dei gas di scarico nel funzionamento al minimo in comunicazione tra il passaggio principale dei gas di scarico ed il passaggio di evacuazione dei gas di scarico nel funzionamento al minimo ed avente una porzione che si estende verticalmente entro il passaggio principale dei gas di scarico e termina in una relazione distanziata al disopra del livello dell'acqua nella carcassa dell'albero motore quando la carcassa dell'albero motore è disposta in una normale posizione operativa e quando la carcassa dell'albero motore è ferma rispetto all'acqua.
