A floating motorized picnic table includes a floatation device; a base; benches attached to the base; tabletop supports; a tabletop attached to the tabletop supports; a motor; and a battery electrically connected to the motor. The base frames and rests upon the floatation device. The benches include bench boards attached above and parallel to the floatation device. The tabletop supports are attached between the benches. The tabletop includes top boards. The battery is mounted on the base under the top boards. The motor is mounted at one end with a retractable keel located adjacent to the opposite end.

A watercraft propulsion system includes an engine, a propeller to be driven by the engine, a generator to be driven by the engine, a rectifier regulator connected to the generator, and a charging controller configured or programmed to control charging of a battery with power generated by the rectifier regulator such that an inductive voltage of the generator approaches one half an inter-terminal voltage of the battery.

A trolling motor has a steering motor transmitting torque to a steering shaft, which is coupled to a lower propulsion unit such that rotation of the steering shaft rotates the propulsion unit about a steering axis. A controller is in signal communication with the steering motor. A foot pedal in signal communication with the controller has a foot pad pivotable about a pivot axis and sends electrical steering signals to the controller (and thus steering motor) in response to pivoting of the foot pad. A variable resistance device is coupled to the foot pedal and controllable to vary resistance to pivoting of the foot pad about the pivot axis based on a position, velocity, acceleration, and/or jerk of the steering shaft. Additionally or alternatively, the variable resistance device provides haptic feedback to a user via the foot pad to inform the user about information related to the trolling motor system.

A method of automatically controlling trim position of a marine drive with a control system on a marine vessel includes receiving a user-selected command associated with wake surfing and then controlling a trim actuator to automatically position the marine drive in a tucked position, tucked position is between a vertical trim position and a minimum running trim position. Once a vessel condition of the marine vessel reaches a first threshold vessel condition the trim actuator is controlled to trim up the marine drive to a predetermined target trim position to generate wave behind the marine vessel. The first threshold vessel condition is at least one of a threshold vessel speed, a threshold engine speed, a threshold engine load, and a threshold vessel pitch.

An outboard propulsion system comprising an engine configured to receive oil; an oil pan configured to receive oil from the engine; and an oil reservoir configured to receive oil from the oil pan and provide oil to the engine, in use.

An alternating current (AC) propulsion system for a boat. The AC propulsion system includes a trolling motor operably mountable to the boat and an AC power system. The trolling motor has a head and a motor housing secured at upper and lower ends, respectively, to an elongated shaft. An AC motor is disposed in the motor housing and drives a propeller. The AC power system includes a generator and a variable frequency drive (VFD). The VFD includes a VFD AC input and a VFD AC output. The VFD AC input is electrically coupled to an AC output of the generator. The VFD AC output is operably electrically coupled to the AC motor of the trolling motor. In some embodiments a second trolling motor with an AC motor may be electrically coupled to a second VFD AC output of the VFD.

A battery pack (e.g., a battery pack for marine environments) can include a lower enclosure having an upper wall and defining a cavity, a plurality of battery cells positioned within the cavity, a radiator assembly positioned above the upper wall of the lower enclosure, a vent in the upper wall of the cavity, and/or a valve configured to selectively facilitate fluid communication between the cavity and the radiator assembly via the vent. In some embodiments, the valve is configured to open in response to increased pressure in the cavity resulting from a thermal runaway event. In some embodiments, the radiator is configured to create a tortuous path and collect flammable particulates from the thermal runaway event.

A power supply system for a watercraft includes a first battery, a second battery, and a battery management device. The battery management device connects the first battery to a first engine to supply an electric power from the first battery to start the first engine. The battery management device connects the second battery to a second engine and a third engine to supply an electric power from the second battery to start the second engine and the third engine.

A propulsion system for a vessel includes an engine propulsion unit that provides a propulsive force to a hull by using an engine as a power source, an electric propulsion unit that provides a propulsive force to the hull by using an electric motor as a power source, a storing mechanism that is displaced from an actuating position to actuate the electric propulsion unit to a storing position to store the electric propulsion unit and performs a storing operation to store the electric propulsion unit, and an interlock controller that interlocks a storing operation of the storing mechanism with generation of a propulsive force by the engine propulsion unit.
