ABSTRACT:
Feathering propeller particularly for auxiliary engines of sailing boats. The propeller comprises a device for transmitting a rotary and a positioning motion to the blades including planetary gear means for converting an angular motion of the drive shaft into an angular motion for inclining the propeller blades and means for halting the angular motion to halt the blades at the required inclination and render the blades of such inclination rigid both with the relative hub and with the drive shaft.
