Abstract: An internal combustion engine assembly has a crankcase, a cylinder block connected to the crankcase, the cylinder block defining at least one cylinder, at least one piston disposed in the at least one cylinder, a crankshaft disposed at least in part in the crankcase and operatively connected to the at least one piston, and a flywheel operatively connected to and driven by the crankshaft. The crankshaft rotates in a first direction about a crankshaft axis. The flywheel rotates in a second direction opposite the first direction about the flywheel axis. A clutch selectively operatively connects the crankshaft to the flywheel. A marine outboard engine having the internal combustion engine assembly is also disclosed.

Abstract: A joystick system and a watercraft using the system are presented. The system includes a joystick having a low range of motion spanning from a rest angle to a threshold angle, and a high range of motion spanning from the threshold angle to a maximum angle; a joystick position sensor for producing signals indicative of a position of the joystick and a control for producing engine thrust request signals to control a resultant thrust of two thrust generation devices in response to receiving the signals from the joystick position sensor, the resultant thrust increasing from a minimum to a threshold thrust at a first rate of increase as the joystick moves from the rest angle toward the threshold angle, the resultant thrust increasing from the threshold thrust to a maximum thrust at a second greater rate of increase as the joystick moves from the threshold angle toward the maximum angle.

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 steering system for a watercraft has steering position sensors sensing a steering position of first and second outboard motors, hydraulic steering actuators for steering the outboard motors, a hydraulic helm selectively supplying hydraulic fluid to the steering actuators, at least one valve for reversing a direction of flow of hydraulic fluid into the steering actuators, and a steering controller. The steering controller executes a realignment process including: receiving signals indicative of the steering positions of the outboard motors from the steering position sensors; based at least in part on the signals, determining if the outboard motors are misaligned; and, if the outboard motors are misaligned, actuating the at least one valve to direct the flow of hydraulic fluid into a corresponding steering actuator in a direction opposite to that corresponding to an active steering direction set by the hydraulic helm so as to reduce misalignment of the outboard motors.

Abstract: A power steering system for an outdrive engine has a steering actuator, a motor for operating the steering actuator, a motor speed sensor for determining at least indirectly a speed of the motor, a steering rate sensor for determining a steering rate, and a controller communicating with the steering rate sensor and with the motor speed sensor. The controller is programmed for determining if a fault has occurred in the power steering system based on the steering rate and the motor speed, and taking at least one steering fault action in response to the fault having occurred. A method for controlling a power steering system includes determining if a fault has occurred based on the steering rate and the speed of the motor, and taking at least one steering fault action in response to the fault having occurred.

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.
