Abstract: A stern and swivel bracket assembly for mounting a drive unit to a watercraft has a stern bracket having first and second laterally spaced portions, a swivel bracket pivotally connected to the stern bracket about a tilt/trim axis, and a hydraulic linear tilt-trim actuator operatively connected between the stern and swivel brackets. The swivel bracket includes a hydraulic steering actuator, and defines first and second hydraulic steer ports facing outward in a first lateral direction. The swivel bracket further includes at least one drive unit mounting bracket connected to the hydraulic steering actuator for connecting the drive unit to the swivel bracket. The hydraulic linear tilt-trim actuator is located laterally between the first and second portions of the stern bracket, and defines trim-up and trim-down hydraulic ports facing outward in a second lateral direction opposite the first lateral direction.

Abstract: A marine outboard engine includes an internal combustion engine assembly that includes an internal combustion engine, a fuse assembly, a fuel filter, a spark plug, a gearcase including one of a propeller and an impeller, a swivel bracket, and a cowling. The cowling includes a service panel disposed on a first lateral side of the internal combustion engine assembly, and an affixed panel disposed on a second lateral side of the internal combustion engine assembly. The service and affixed panels define a split line therebetween and are removably attached to each other. The fuse assembly, the fuel filter, and the spark plug are mounted to one of the first lateral side and the affixed panel proximate to the split line and are at least in part accessible from the first lateral side when the service panel is detached and removed from the affixed panel.

Abstract: A marine outboard engine for a watercraft has a stern bracket for mounting the marine outboard engine to the watercraft, a swivel bracket pivotally connected to the stern bracket about a generally horizontal tilt/trim axis, and a drive unit pivotally connected to the swivel bracket about a steering axis. The steering axis is generally perpendicular to the tilt/trim axis. A hydraulic actuator is operatively connected to the stern bracket and the swivel bracket for pivoting the swivel bracket and the drive unit relative to the stern bracket about the tilt/trim axis. A pump is mounted to the swivel bracket. The pump is pivotable about the tilt/trim axis together with the swivel bracket. The pump is fluidly connected to the hydraulic actuator to supply hydraulic fluid to the hydraulic actuator.

Abstract: A gear case assembly for a marine propulsion system has a gear case, a driveshaft, a propeller shaft, and a transmission chamber. A driveshaft passage fluidly connects to the transmission chamber. A lubricant return passage fluidly connects to the transmission chamber and the driveshaft passage. A pump is driven by the driveshaft. A first lubricant filling port fluidly communicates one of the lubricant return passage and the driveshaft passage with an exterior of the gear case. A second lubricant filling port fluidly communicates one of the lubricant return passage and the transmission chamber with the exterior of the gear case. First and second plugs are selectively disposed in the first and second lubricant filling ports respectively. A check valve is disposed in the lubricant return passage between the first and second lubricant filling ports. The check valve prevents lubricant to flow through the check valve away from the transmission chamber.

Abstract: A tiller assembly includes a base and a tiller arm pivotably connected to the base. One of the base and the tiller arm defines a recess. The recess is at least partially defined by a female tapered surface. A shaft extends through the base and the tiller arm and has a first threaded portion. A clamping fitting is connected to the shaft and received in the recess. The clamping fitting is rotationally fixed relative to another one of the base and the tiller arm and has a male tapered surface. One of a handle and the clamping fitting has a second threaded portion engaged with the first threaded portion. Rotation of the first threaded portion relative to the second threaded portion in a pre-determined direction causes the male tapered surface to press against the female tapered surface. A marine outboard engine and a tiller assembly kit are also provided.

Abstract: A hydraulic steering system for a watercraft has first and second hydraulic steering actuators for steering first and second outdrives respectively, at least one hydraulic pump selectively supplying hydraulic pressure to at least one of the first and second actuators, a steering controller operatively connected to the at least one pump, a hydraulic helm selectively supplying hydraulic pressure to the first and second actuators, an auxiliary steering input device connected to the controller, and at least one mode selection valve having first and second mode positions for steering the watercraft in first and second steering modes respectively. In the first steering mode, the hydraulic helm is hydraulically connected to the first and second actuators. In the second steering mode, the hydraulic helm is hydraulically disconnected from the first and second actuators. A watercraft having the steering system and a method for steering a watercraft are also disclosed.

Abstract: A hydraulic system for a marine engine has a fluid reservoir, a bi-directional pump, a valve assembly, and a hydraulic actuator. The valve assembly includes: first and fourth apertures fluidly communicating with the pump, second and third apertures fluidly communicating with the actuator, and a fifth aperture fluidly communicating with the fluid reservoir. Operating the pump to supply hydraulic fluid to the first aperture causes hydraulic fluid to flow from the pump to the actuator and from the actuator to the fluid reservoir, and causes the actuator to move in a first actuator direction. Operating the pump to supply hydraulic fluid to the fourth aperture causes hydraulic fluid to flow from the pump to the actuator and from the actuator to the pump, and causes the actuator to move in a second actuator direction opposite the first actuator direction.

Abstract: A tiller system has a tiller adapted for steering at least one of a bracket assembly and a motor assembly of a marine outboard motor having a power steering system, a throttle control mounted to the tiller, an electronic torque sensor, and a tiller system control module (TSCM) in electronic communication with the electronic torque sensor. The electronic torque sensor senses torque applied to the tiller and outputs an electronic steering signal as a function of the torque. The TSCM receives the electronic steering signal and controls an operation of the power steering system in response to the electronic steering signal. A method for steering a marine outboard motor, and a marine outboard motor having a tiller system are also described.
