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 surface (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.
