A watercraft running system includes a propulsion device, a steering device, a course changing operator, a port-side attitude control plate and a starboard-side attitude control plate, a port-side actuator and a starboard-side actuator, and a controller. The controller is operable in a first control mode in which the steering device is controlled according to the operation of the course changing operator and a second control mode in which the port-side actuator and the starboard-side actuator are controlled according to the operation of the course changing operator. The controller is configured or programmed to prohibit shifting from the first control mode to the second control mode if the steering position of the steering device is not a neutral position, and to permit the shift from the first control mode to the second control mode if the steering position is the neutral position.

Various examples of a tool for lubricating a boat steering cable are described, along with examples of using the tool. In one example, a tool for lubricating a boat steering cable includes a lubricator barrel and a threaded lubricator pin. The lubricator barrel includes an outer cylindrical surface, a first end surface, and a second end surface. The lubricator barrel also includes a central barrel cavity extending from the first end surface, along a longitudinal centerline of the lubricator barrel, and a pin cavity extending from the outer cylindrical surface to the central barrel cavity. In some cases, the lubricator barrel also includes a first o-ring seat, a second o-ring seat, or both. The first o-ring seat is positioned at one end of the central barrel cavity and the second o-ring seat is positioned at the outer cylindrical surface of the pin cavity.

An outboard motor includes a drive shaft cover to cover a drive shaft extending downwardly from an engine, a lower unit turnable with respect to the drive shaft cover, and a harness. A lower housing of the lower unit houses a lower portion of the drive shaft and an electrical component. The harness is connected to the electrical component through an upper space provided in the drive shaft cover and through a lower space that communicates with the upper space from below in the lower housing.

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.
