Abstract: The present invention discloses a folding propeller (1) for a boat, e.g. for a sailboat or a multihull yacht, where said folding propeller (1) comprises a hub (2) for directly or indirectly fastening at a driveshaft connected to a motor, where said folding propeller (1) further comprises at least three individual blades (3), where each of said blades (3) comprises a blade root (4) arranged to pivot around a separate pivot pin (9), at said hub (2) in order to be either in a first and operative position, where the blade (3) is pointing mainly in a radial direction, or in a second and inoperative position, where the blade (3) is pointing mainly in an axial direction, where said pivot pin (9) comprises a first and second end (20, 21), where said hub (2) comprises a cut out (19) for each of said blade roots (4), and further comprises a set of holes (10) for installing said pivot pins (9).

Abstract: The present invention relates to a foldable propeller (1) for a boat, e.g. for a sailboat or a multihull yacht, where the foldable propeller (1) comprises a hub (2) with a plurality of blades, each blade comprising a blade root arranged to pivot around a separate pivot pin in order to be either in a first operative orientation, where the blade (4) is pointing mainly in a radial direction, or in a second inoperative orientation, where the blade is pointing mainly in an axial direction. The hub (2) comprises a number of hub flanges (28) for holding the pivot pins (9). The pivot pin (9) comprises at its second end (21) a head (26) with a recess (24) that accommodates the first end (20) of another of the pivot pins (9) inside the head (26).

Abstract: A folding propeller for a boat, e.g., for a sailboat or a multihull yacht, and a method for installing and/or adjusting such a folding propeller, where said folding propeller has a hub for directly or indirectly fastening at a driveshaft connected to a motor, where said folding propeller further has at least two individual blades, where each of said blades has a root arranged to pivot around a pivot pin at said hub to be either in a first, operative position, where the blades are pointing mainly in a radial direction, and in a second, inoperative position, where the blades are pointing mainly in an axial direction, where said hub has one or more cut outs for said blades roots and further has a first set of holes for installing said pivot pins and a second set of holes for installing a locking device for engagement with said pivot pins.
