Marine controllable-pitch propeller, propeller system for a boat and boat including the same

Abstract

A marine controllable-pitch propeller is mounted on a drive shaft. The marine controllable-pitch propeller has a propeller blade comprising an offset pitch interface, a pitch adjusting member that is adapted to be linearly movably mounted on the drive shaft and connected to the offset pitch interface, such that a linear motion of the pitch adjusting member along the drive shaft results in a pitch adjustment of the propeller blade, a rotary actuator, a linear actuator operationally arranged between the rotary actuator and the pitch adjusting member, and translation means for translating a rotary motion of the rotary actuator about the drive shaft into a linear motion of the linear actuator along the drive shaft. The pitch adjusting member is rotationally fixed to the propeller blade.
