A trolling motor is provided for attachment to a watercraft. The trolling motor includes a system for steering and trimming a trolling motor. The system includes a trolling motor shaft attachment feature configured to receive and rotate with a trolling motor shaft about a trolling motor shaft axis. The system further includes a steering system having a steering motor configured to rotate the shaft attachment feature and shaft to steer a facing direction of the trolling motor. The trim system includes a trim module having a trim motor configured to cause the trolling motor shaft to raise or lower with respect to the steering system so as to cause the trolling motor to raise or lower with respect to the watercraft. The trim module is disposed on the shaft attachment feature such that the trim module rotates with the trolling motor shaft attachment feature about the shaft axis.

A hybrid ship propulsion machine includes an internal-combustion-drive propulsion part, a fixing bracket configured to fix the internal-combustion-drive propulsion part to a ship, an electric propulsion part, an elevating device configured to elevate and lower the electric propulsion part; and an attachment bracket attaching the electric propulsion part and the elevating device to the fixing bracket. The elevating device is configured to elevate and lower the electric propulsion part between a position where a second propeller of the electric propulsion part sinks below a water surface and a position where the second propeller comes out of the water surface.

A system includes an outboard motor including a lift actuator, a pitch angle sensor, a lift position sensor, and a controller configured or programmed to obtain at least either of a pitch angle of a watercraft and an angular velocity of the pitch angle. The controller is configured or programmed to obtain a lift position of the outboard motor, and controller selectively set either a lift-up direction or a lift-down direction as a lift direction based on the lift position of the outboard motor and at least either of the pitch angle of the watercraft and the angular velocity of the pitch angle. The controller is configured or programmed to control the lift actuator to cause the outboard motor to perform a lift motion in the lift direction.

A cable management device for managing cables of a trolling motor is provided. The cable management device can slide axially along a shaft of a trolling motor while being affixed to a portion of a cable of the trolling motor. A trolling motor including such a cable management device is provided.

A system includes an outboard motor, a lift actuator, a sensor, and a controller. The sensor detects motion information indicating an up-and-down directional motion of a bow of a watercraft. The controller is configured or programmed to selectively set either a lift-up direction or a lift-down direction as a lift direction in accordance with the up-and-down directional motion of the bow based on the motion information. The controller is configured or programmed to control the lift actuator to cause the outboard motor to perform the lift motion in the lift direction, and set a duration of the lift motion to be different between when the outboard motor is caused to perform the lift motion in the lift-up direction and when the outboard motor is caused to perform the lift motion in the lift-down direction.

An entertainment barge includes at least two pontoons, a first deck having a front, rear, right side and left side, is attached to both pontoons. A second deck is disposed above and substantially parallel to the first deck. At least two retractable spuds are attached to the deck and are adapted to be lowered into the water to secure the barge in a fixed position.

A cable management device for managing cables of a trolling motor is provided. The cable management device can slide axially along a shaft of a trolling motor while being affixed to a portion of a cable of the trolling motor. A trolling motor including such a cable management device is provided.

A marine device assembly, such including a trolling motor and/or at least one sonar transducer, is provided for attachment to a watercraft. The trolling motor and/or sonar transducer is attached at an end of a shaft. The marine device assembly includes a position adjustment assembly comprising a plurality of rotatable drums surrounding the shaft that are configured to adjust the rotational and/or vertical position of the trolling motor and/or sonar transducer(s) in accordance with a position adjustment command. In various aspects, the drums are configured to independently rotate about the shaft in a clockwise or counterclockwise direction so as to cause the trolling motor and/or sonar transducer(s) to rotate about the central axis of the shaft and/or translate along the central axis of the shaft.

A trolling motor includes a rotatable trim module which effectuates trim adjustment of the trolling motor by adjusting a vertical position of a motor shaft assembly. A rotatable steering module is mounted below the trim module. The steering module and trim module are assembled on a rotatable motor shaft having a motor mounted at one end of the motor shaft. A conductive cord is coiled around the motor shaft. The conductive cord is configured to transmit electrical power from a power source to an internal control module and a drive motor in the trim module. In further embodiments, the conductive cord also transmits control signals from an internal control device to an internal control module in the trim module.

An outboard motor and methods of use thereof in general, includes a powerhead removeably affixed to the transom of a boat, and a gear case rotationally connected to a propeller shaft, the outboard motor including a telescopic drive shaft, the telescopic drive shaft having a first drive shaft section rotationally connected to the motor and a second drive shaft section rotationally connected to the gear case, and a telescopic drive shaft housing, the telescopic drive shaft housing configured to support the telescopic drive shaft internally therethrough, whereby the telescopic drive shaft and the telescopic drive shaft housing are configured to provide depth adjustment for the gear case and the propeller shaft, and thus enable the propeller to be raised and lowered during propulsion to improve propulsion efficiency.
