Abstract:
A propeller for a marine propulsion system is disclosed which comprises a propeller hub having a casing formed from three segments (16a, 16b, 16c), each of which has a part of an opening (28) for mounting a propeller blade (34). A locking and unlocking mechanism (51, 54, 95, 100) is provided for disengaging the propeller blades to enable pitch adjustment of the blades. A push rod (50) is connected to the mechanism (100) to cause disengagement and adjustment of the pitch of the blades. The mechanism (100) includes a claw (101) having pivotally connected fingers (95). The hub also has a slide ring (51) having a load surface (61) is provided for receiving load when the propeller blades are unlocked to enable pitch adjustment to take place.
