    Abstract: A steering system for a marine craft includes a steering input shaft. The steering system also includes an electric power steering (EPS) system operatively coupled to the steering input shaft, the EPS system having an electric motor that drives rotation of a system output shaft. The steering system further includes a hydraulic pump operatively coupled to the system output shaft with a gear set, the hydraulic pump having a longitudinal direction that is perpendicular to a steering input shaft axis. The steering system yet further includes a fluid reservoir located remotely relative to the hydraulic pump.

    Abstract: A power-assist assembly comprising a housing including a drive axle portion extending between a pair of extension sleeve connection ends spaced along a first axis and an input gear portion extending along a second axis transverse to the first axis. A gear assist housing is connected to the input gear portion. A boot assembly connected to at least one of the extension sleeve connection ends. The boot assembly includes an extension sleeve connected to the extension sleeve connection end, a boot sleeve connected to the extension sleeve and spaced from the extension sleeve connection end of the housing by at least a portion of a length of the extension sleeve, and a boot retaining ring connected to the boot sleeve opposite the extension tube.

    Abstract: A rotation limiting device for a steering system includes a steering shaft rotatable during steering motion. The rotation limiting device also includes a stationary feature. The rotation limiting device further includes a first plate having a face defining a slot extending from a first end to a second end. The rotation limiting device yet further includes a second plate having a face defining a spiral shaped recess extending from a first spiral end to a second spiral end. The rotation limiting device also includes a ball bearing partially disposed within the spiral shaped recess and the slot, wherein one of the first plate and the second plate is fixed to the stationary feature, and the other of the first plate and the second plate is fixed to the steering shaft and rotatable therewith.

    Abstract: A method for steering control for a marine vessel includes determining a first position of a hand wheel of the marine vessel. The method also includes determining, after a first period, a second position of the hand wheel. The method also includes determining a difference between the first position of the hand wheel and the second position of the hand wheel. The method also includes, in response to a determination that the difference between the first position of the hand wheel and the second position of the hand wheel is less than a threshold: capturing a first heading of the marine vessel; and selectively controlling steering of the marine vessel according to the first heading.
