CA 2604978

A jet pump for an outboard propulsion marine engine includes a support member and at least one impeller blade extending helically from said support member. At least one induction blade extends helically from said support member. A stator having a volume reduction member is disposed downstream of the blades. The jet pump is supported in a housing having a stepped profile to reduce drag. A single lever controls both the speed and direction of the jet stream exiting the stator.

La présente invention concerne un pompe à jet conçue pour un moteur hors-bord de propulsion marine, qui comporte un élément de support et au moins une aube de roue s'étendant de manière hélicoïdale à partir dudit élément de support. Un stator ayant un élément de réduction de volume est disposé en aval des aubes. La pompe à jet est logée dans un carter ayant un profil étagé permettant de réduire la traînée. Un unique levier commande à la fois la vitesse et la direction du jet de fluide sortant du stator.
