Abstract

The boat drive propeller has propeller blades (2a,2b,2c) arranged symmetrically on an end-side of a drive shaft flange (1). An inflow opening (3) of a tapering channel (5) is provided on a leading edge of each propeller blade. The channel opens in an outflow opening (4) in an area of a trailing edge of a propeller blade. The propeller blade is made from a U-shaped sheet metal, whose opposing shank sides (6a,6b) together with a bottom side (7) form the tapering channel. A sheet metal of the propeller blade and the drive shaft flange is made from steel of same alloy.
