The propeller protection apparatus includes one or more deflecting members; one or more support members; one or more removable axles; and two or more removable wheels.
Claims7
A propeller protection apparatus surrounding a turnable propeller assembly operating beneath a bottom hull of a watercraft comprising:
- one or more deflecting members each independently coupled to the bottom hull of the watercraft,
- wherein the one or more deflecting members each independently having a first section, a second section, and a third section,
- wherein the second section of each of the one or more deflecting members each independently extend substantially parallel to the bottom hull of the watercraft,
- wherein the one or more deflecting members each independently extend beyond a stern of the watercraft and below a lowest point of the turnable propeller assembly;
- one or more support members each independently coupled to the one or more deflecting members,
- wherein the one or more support members are positioned in front of a propeller blade in the turnable propeller assembly;
- one or more removable axles each independently transversely coupled to each of the one or more deflecting members,
- wherein the one or more removable axles each independently having a first end and a second end;
- and
- two or more removable wheels each independently coupled to the first end and the second end of each of the one or more removable axles.

- two deflecting members each independently coupled to the bottom hull of the electric-powered watercraft,
- wherein the two deflecting members each independently having a first section, a second section, and a third section,
- wherein the one or more deflecting members each independently extend beyond a stern of the electric-powered watercraft and below a lowest point of the turnable propeller assembly,
- wherein the first section of each of the two deflecting members each independently extend downward from the bottom hull of the electric-powered watercraft forming an angle of less than ninety degrees to a plane of the bottom hull of the electric-powered watercraft,
- wherein the second section of each of the two deflecting members each independently extend substantially parallel to the bottom hull of the electric-powered watercraft;
- one support member transversely coupled to the two deflecting members,
- wherein the support member is positioned in front of a propeller blade in the turnable propeller assembly;
- one axle transversely coupled to each of the two deflecting members,
- wherein the one axle has a first end and a second end;
- two removable wheels each independently coupled to the first end and the second end of the one axle;
- and
- wherein the turnable propeller assembly turns around a vertical axis for steering the electric-powered watercraft.
