Abstract
A boat propelling assembly includes a single support unit which includes a thrust articulation and horizontal and vertical movement members controlled by a horizontal actuation element. Manual or automatic inclination control is also provided by a control system to determine the inclination of the propelling member to which the propeller is engaged, so as to keep the propeller totally or partially submerged.
Claims23
A boat propelling assembly comprising:
- a propelling member having a thrust ball at an end thereof, a shaft and a propeller, said shaft being adapted to be coupled to an engine,
- a control arm having first and second coaxially disposed ends, a movable ball member being disposed between said first and second ends, said first end being movably coupled to said propelling member;
- and
- a support unit adapted to be coupled to an external lower side of a boat stern for housing said thrust ball of said propelling member and said movable ball member of said control arm so as to integrate articulation of said control arm and said propelling member to permit horizontal and vertical movement of said propelling member,
- said second end of said control arm being adapted to extend within an interior of a boat, movement of said second end of said control arm provides horizontal control of said propelling member so as to adjust steering, said control arm providing vertical control of said propelling member upon axial extension of said first end of said control arm so a to adjust propeller submersion.
