Marine vessel propulsion systems and methods for controlling speed and direction of marine vessel propulsion systems. A processing device can receive, from a user device, a signal indicative of a desired direction and speed input to the user device; store the desired direction and speed signal in the memory; generate control signals indicative of a power input, wherein each of the control signals is associated with a particular motor of the marine vessel propulsion system; and transmit each of the control signals to a corresponding one of the motors to move the marine vessel in a desired direction and at a desired speed.

Structural arrangement for a water ski or underwater ski comprising essential mechanisms for significantly improving the user experience in underwater wake bodyboarding. The ski is characterized by the addition of novel and different attachable items that enable the ski to be used without a powered vehicle. The ski is also characterized in that it has various different items that can be attached to the cowling to improve the performance and comfort of the equipment, combined with a personalized steering system and an essential safety system, providing a model that is unique on the underwater ski/water ski market.

A visual direction guide for a fishing boat trolling motor to enable a fisherman or other operator positioned remotely in the boat from the trolling motor to visually determine the direction of propulsion of the trolling motor so the operator can steer the motor even when the view from the operator of the trolling motor is visually obstructed by another fisherman, chair, or other object. The visual direction guide has a support shaft, a visual indicator located at the top of the support shaft, and mounting apparatus to secure the support shaft to the trolling motor, so that the visual indicator can be seen by the operator above any visual obstruction to determine the direction of propulsion of the trolling motor to remotely steer the trolling motor. The visual indicator can include a vane, and can include lights. The support shaft can telescope, fold down, or be removed for storage.

A control system for a steerable thrusting device is disclosed comprising a mobile device and application which interface with an electronic controller to command the output power and directional heading of the steerable thrusting device. In at least one embodiment, the mobile device serves the functions of a mapping and input device that communicates bi-directionally with a Global Navigation Satellite System (GNSS) and direction device-equipped electronic controller, which in turn controls the power and heading of the thrusting device on a marine vessel. Data can be stored on the mobile device or procured in real-time via network access to a dedicated database and communicated to the electronic controller in order to execute specific functions of the thrusting device control system. The data created can be shared over a cloud network. A feature control system is introduced for alternately enabling and disabling features of the steerable thrusting device control system.

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.

A towing device for a rider on a body of water comprises a buoyant platform having at least one electric motor and a prop. A container fixed with the towing device contains a controller to power each electric motor. A wireless remote control sends wireless commands to the controller. A tow rope is fixed with the buoyant platform proximate the rear end. As such, with the rider holding the wireless remote control and engaged with a distal end of the two rope, commands from the wireless remote control are sent to the controller to control power to each electric motor. Preferably the towing device further includes a pivotable rudder that is disposed behind the prop, or a steering nozzle, and the wireless remote control has a steering control to send steering signals to the controller. Various modes of operation of the towing device are disclosed.
