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 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.

Abstract: A marine motor assembly for mounting to a watercraft is disclosed. The marine motor assembly has a motor unit including a motor unit housing, a motor, a propulsion device, an air pump fluidly communicating with an under-housing volume of the motor unit housing, a pressure sensor for measuring air pressure in the under-housing volume, and a control unit communicating with the air pump and the pressure sensor. The control unit is programmed for controlling the air pump for changing air pressure in the under-housing volume, and monitoring change in the air pressure for a predetermined amount of time for confirming that the motor unit housing is water-resistant, or that the water resistance of the motor unit housing is compromised. A method for testing a water resistance of a motor unit housing of a marine motor assembly is also disclosed.
