Abstract: A marine propulsion system comprising a push rod (50) for adjusting the pitch of propeller blades (34). The push rod (50) has a screw-threaded bolt (60) engaged with a nut (78). The nut (78) carries a bevel gear (84) by which the nut (78) can be rotated to cause the bolt (60) and therefore the push rod (50) to move longitudinally. The push rod (50) is connected to a claw with arms couple with pins (170). The pins (170) engage eccentric shafts (174) for unlocking a propeller base (190) so the base (190) can rotate around a transverse axis. The base (190) has an inclined surface which engages with an inclined surface defining an opening in the propeller’s hub therefore locking the propeller blade (34) in position. The inclined surfaces are disengaged by rotation of the eccentric shaft (174) thus the propeller blades (34) can be rotated to adjust the pitch and than the inclined surfaces re-engage locking the propeller blade (34) in the pitch adjusted position.

Abstract: A marine propeller comprises a hollow hub body (11), a plurality of propeller blades (16) and a plurality of fastening devices (19, 21) for each propeller blade (16). Each fastening device includes a tension rod (19) and a flange member (22) mounted on the tension rod. The propeller blades (16) may be turnable for adjustment of the blade pitch angle ( alpha ) and lockable in a selelcted position by means of the fastening devices (19, 21). The flange member (22) has a plurality of recesses (23) and tensioning members (24) received in the recesses. These tensioning members (24) are extendable from the flange member (22) towards the hub body wall (14) to apply tension to the tension rod (19).

Abstract: A marine propulsion system comprising a push rod activated pins (170) which engage eccentric shaft (174) for unlocking a propeller base (190) so the base (190) can rotate around a transverse axis. The base (190) has an inclined suface (192) which engages with an inclined surface (159) defining an opening in the propeller’s hub therefore locking the propeller blade (34) in position. The inclined surfaces (159, 192) are disengaged by rotation of the eccentric shaft (174) thus the propeller blades (34) can be rotated to adjust the pitch and then the inclined surfaces (159, 192) re-engage to locking the propeller blade (34) in the pitch adjusted position.
