Abstract:

A portable propulsion system for a watercraft may include a shaft, a propeller, an outer casing, and a flexible strap. The shaft may have a prop end section, a drive end section, and a rotational axis extending from the prop end section to the drive end section. The propeller may be connected to the prop end section of the shaft. The drive end section may be configured for removable connection to a driver for rotation of the propeller via rotation of the shaft about the rotational axis to propel the watercraft. The outer casing may be disposed around the shaft. The flexible strap may have first and second end sections connected to the outer casing in respective first and second regions.

Appl. No.:

14/099858

Inventors:

Gene L. Keough - Klamath Falls OR, US

International Classification:

F04D 13/08

US Classification:

4174101, 416 69

Abstract:

A portable propelling system including a driver removably coupled to a drive end portion of a shaft, and a propeller connected to a prop end portion of the shaft. The shaft may extend through an outer casing. The driver may be configured to rotate the shaft and the propeller about a rotational axis of the shaft relative to the outer casing. One or more water-buoyant components, such as one or more sections of polymeric closed-cell foam, may be disposed around the outer casing. A flexible strap may be coupled to the outer casing. A first end portion of the flexible strap may be operable between a connected position and a towing position. The system may be a telescoping system operable between collapsed and extended positions along the rotational axis.
