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 tiller system for a marine outboard engine having a tiller bracket is described. The tiller system comprises a tiller for mounting to the tiller bracket. A speed input control is mounted to the tiller and a speed input control position sensor detects a position of the speed input control. A control unit is mounted to the tiller and is operatively connected to the speed input control position sensor. The control unit converts the position of the speed input control into a speed input message. A digital communication port of the control unit transmits the speed input message to the marine outboard engine over a controller area network bus. A marine outboard engine having the tiller system and a marine outboard engine system for a watercraft are also described.

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.

A motor operatively connected to the steering actuator is mounted to the bracket and rotationally fixed with respect thereto about the steering axis. A control module includes a motor drive electrically connected to the motor and configured to be connected to a power source. An electrically conductive thermal element is electrically connected to the motor. A temperature of the thermal element is indicative of a temperature of the motor. A controller is configured to obtain the temperature of the thermal element and to control power delivered to the motor via the motor drive based at least in part on the temperature of the thermal element. The controller and the thermal element are mounted to the drive unit and pivotable therewith about the steering axis.
