A system (10) for adjusting the pitch of a counter-rotating propeller has a propeller shaft (18), a forward propeller (22) driven by the propeller shaft, and an aft propeller (24) connected with the forward propeller. The forward propeller has a hub (26), blades (28) mounted within the hub, and an actuator (52) connected with an end of the blades. The aft propeller has a hub (32), blades (34) mounted within the hub, and a cam assembly (86) connected with an end of the blades. The actuator of the forward propeller has a forward end and an aft end, wherein the aft end is connected with the cam assembly (86) of the aft propeller. Thus, when the actuator (52) moves in an axial direction, the cam assembly moves relative to the actuator and the pitch of the forward propeller blades (28) and the pitch of the aft propeller blades (34) are simultaneously adjusted.
