A system and apparatus are disclosed for improving safety and hydro-flow thrust from a hydro-drive device. The apparatus may include a shroud having a first opening for the ingress of water, and a second opening for the egress of water, and a vane extending inward from an interior surface of the shroud. The vane is configured to direct water to form a vortex that exits the shroud. The vane may include a fixed, planar region and a moveable, curved region attached to an interior surface of the shroud. Alternatively, the vane may be attached to a surface of a paddle configured to adjust the diameter of the second opening. The system may include a motor, a hydro-drive device coupled to the motor, the shroud, and the vane.

What is claimed is: 1. An apparatus for directing fluid from a hydro-drive device, the apparatus comprising: a shroud having a first opening for the ingress of water, and a second opening for the egress of water; a vane extending inward from an interior surface of the shroud and angled in a direction selected to direct water into a vortex as the water exits the shroud; and a connector mechanism configured to connect the shroud to the hydro-drive device. 2. The apparatus of claim 1, wherein the vane comprises a planar region directly attached to an interior surface of the shroud and a curved region configured to change curvature in response to increasing or decreasing thrust from the hydro-drive device. 3. The apparatus of claim 1, wherein the vane is formed of a material having a tension configured to allow the curvature of the vane to change in response to an increased thrust of the hydro-drive device and to return to an original configuration upon a decreased thrust. 4. The apparatus of claim 1, further comprising a spring tension bar having a first end coupled to the interior surface and a second end removably coupled to a paddle. 5. The apparatus of claim 4, wherein the paddle is configured to adjust the diameter of the second opening in response to thrust from the hydro-drive device. 6. The apparatus of claim 5, wherein the vane is directly connected to a surface of the paddle. 7. The apparatus of claim 1, further comprising at least a second vane, the vane and the second vane extending toward each other and intersecting with each other. 8. The apparatus of claim 1, further comprising a plurality of vanes extending toward the interior of the shroud, each vane configured to direct water to form a vortex that exits the shroud. 9. The apparatus of claim 1, further comprising a mounting plate coupled to an outside surface of the shroud, the mounting plate configured to couple the shroud to a vehicle. 10. The apparatus of claim 1, wherein the shroud is configured to at least partially enclose the hydro-drive device. 11. The apparatus of claim 1, wherein the connector mechanism comprises a mounting plate coupled to an exterior surface of the shroud, the mounting plate configured to removably couple to a surface of a marine vehicle. 12. The apparatus of claim 1, wherein the connector mechanism comprises a skeg coupler connected to the exterior surface of the shroud, the skeg coupler configured to slidably couple to a skeg of the marine vehicle. 13. The apparatus of claim 12, further comprising a keyed fastening device for coupling the skeg coupler to the skeg, the unique fastening device configured to prevent theft of the shroud or the hydro-drive device. 14. The apparatus of claim 1, further comprising a collar coupled with an outside surface of the shroud and configured to securely engage a down shaft of a trolling motor, the collar formed of a removably coupled portion and a portion fixed with the shroud, the portions configured to surround the down shaft. 15. The apparatus of claim 1, further comprising a thumbscrew configured to couple the removably coupled portion to the fixed portion and securely engage the down shaft. 16. The apparatus of claim 1, wherein the vane is formed having a curvature throughout the length of the vane. 17. The apparatus of claim 1, wherein the vane is formed having a curvature at the distal end of the vane. 18. A system for directing fluid from a hydro-drive device, the system comprising: a motor; a hydro-drive device coupled to the motor; a shroud having a first opening for the ingress of water, and a second opening for the egress of water; a vane extending inward from an interior surface of the shroud and angled in a direction selected to direct water into a vortex as the water exits the shroud; and a connector mechanism configured to connect the shroud to the hydro-drive device. 19. The system of claim 18, wherein the vane is formed of a material having a tension configured to allow the curvature of the vane to change in response to an increased thrust of the hydro-drive device and to return to an original configuration upon a decreased thrust. 20. The system of claim 18, further comprising a spring tension bar having a first end coupled to the interior surface and a second end removably coupled to a paddle. 21. The system of claim 20, wherein the paddle is configured to adjust the diameter of the second opening in response to thrust from the hydro-drive device. 22. The system of claim 18, wherein the connector mechanism comprises a mounting plate coupled to an outside surface of the shroud, the mounting plate configured to couple the shroud to a marine vehicle.
