ABSTRACT:
This invention relates to hollow hub marine propellers provided with an external groove girdling the hub disposed between the propeller blades and the rear hub opening. The walls of the groove or annular cavity do not extend outwardly of the hub and thereby offer minimal water resistance. The groove serves to minimize forward migration of exhaust gas issuing from the rear end of the hub, thus to minimize blade cavitation.
