A boat speed control device for a boat including a manual shifter and an outboard motor, includes an actuator and a controller. The outboard motor is operably connected to the manual shifter. The manual shifter includes a shift lever shiftable between a sailing position and a neutral position. The actuator is connected to the shift lever. The controller is configured or programmed to control the actuator to shift the shift lever to the sailing position and the neutral position.

A hydrofoiling watercraft is disclosed that includes a board having a top surface for supporting a user and a bottom surface. Extending from the top surface of the board is a handlebar. Extending from the bottom surface of the board is a hydrofoil including a strut and a hydrofoil wing. A propulsion system is attached to the hydrofoil.

An electric outboard motor includes an outboard motor main body that includes an electric motor and a tiller handle that turns together with the outboard motor main body with respect to a hull. The tiller handle includes a handle bar that turns together with the outboard motor main body with respect to the hull, an accelerator grip that is rotatable with respect to the handle bar and that is rotated when the electric motor is rotated, and a shift switch located closer to a distal end of the accelerator grip with respect to a proximal end of the accelerator grip and that is operated when a shift state of the outboard motor main body is switched between a forward mode and a reverse mode.

A marine vessel electric propulsion system includes an electric motor, a propulsive force generator to be driven by the electric motor to generate a propulsive force, an operator to be operated by a user to adjust the power output of the electric motor, and a controller. The controller is configured or programmed to control the power output of the electric motor based on an operation of the operator, and to change a power output gain characteristic of the electric motor with respect to an operation amount of the operator in response to a gain change command.

A tiller for an outboard marine drive includes a tiller body that is elongated along a tiller axis between a fixed end connected to an outboard marine drive and a distal end. A lanyard switch on the tiller body is configured to prevent operation of the outboard marine drive when a lanyard clip is not attached to the lanyard switch. A controller is configured to identify that an operator has provided user input to start the outboard marine drive and that the lanyard clip is not connected to the lanyard switch. The controller then generates a lanyard error alert identifying that the lanyard clip is not connected to the lanyard switch.

A control system for a marine vessel that includes a drive source and an operator that receives an operation is able to switch a control mode of the drive source without providing an additional operator. An operation received by the operator when the drive source is resting is disabled, and a function of switching a control mode of the drive source is assigned to the operation of the operator that is received when the drive source is resting.

One embodiment of the invention comprises a method for controlling a marine vessel having a first steerable propulsor, a corresponding first reversing device, a second steerable propulsor and a corresponding second reversing device. The method comprises receiving a first vessel control signal corresponding to a rotational movement and no translational movement command, generating at least a first actuator control signal and a second actuator control signal in response to the first vessel control signal, coupling the first actuator control signal to and controlling the first steerable propulsor and the second steerable propulsor, and coupling the second actuator control signal to and controlling the first reversing device and to the second reversing device. The method creates rotational forces on the marine vessel with substantially no translational forces on the marine vessel.

A system for controlling a marine vessel having first and second waterjets, corresponding first and second steering nozzles and corresponding first and second reversing buckets. The system comprises a speed control device for providing a first vessel control signal that corresponds to a speed to be provided to the marine vessel, a processor configured to receive the first vessel control signal and that is configured to provide at least one first actuator control signal coupled to the first and second waterjets, and at least one second actuator control signal coupled to the first and second steering nozzles and the first and second reversing buckets. The system any of improves upon turns provided by conventional waterjet propulsion systems, improves upon slowing down or stopping marine vessels as is done by conventional waterjet propulsion systems, and improves upon the controllability of the waterjet propulsed marine vessel at low vessel speeds.

A ship includes an out-drive unit that exerts a propulsion force on a ship hull by power from an engine; a detection device for detecting a current position, a bow direction, and a moving speed of the ship hull; a brake pedal that limits a moving speed of the ship hull; a brake sensor that detects a foot-pushing amount on the brake pedal; and a ship steering control device connected to the out-drive unit, the detection means, and the brake sensor. The ship steering control device acquires an operating status of the out-drive unit and detection results obtained by the detection device and the brake sensor, and controls the out-drive unit based on the detection results. The ship steering control device changes the output of the out-drive unit in accordance with a foot-pushing amount on the brake pedal.

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.
