A marine drive is for propelling a marine vessel. The marine drive has a propulsor configured to generate a thrust force in a body of water, an electric motor which powers the propulsor, a battery having a battery port for outputting battery power, a supporting frame which supports the marine drive relative to marine vessel, the supporting frame having a frame interior which retains the batter, and a cowling on the supporting frame. The cowling has a first cowl portion and a second cowl portion which is movable relative to the first cowl portion into a closed position enclosing the supporting frame and the battery in a cowling interior and alternately into an open position providing access to the cowling interior enabling insertion and removal of the battery.

A dynamic active control system (DACS) configured for: (1) total vessel pitch axis control by fast symmetric deployment of water engagement devices (WEDs) or controllers, coupled with engine trim adjustments; (2) total roll and heading control by differentially deploying WEDs to counter rolling motions while simultaneously adjusting engine steering position to counter the steering moment associated with WED delta position; and (3) adjustment of the engine steering angle to counter yaw moments produced by gyroscopic stabilization systems.

An engine cover of an outboard motor includes an upper cover and a lower cover that are vertically separable. A fixing belt capable of fixing the upper cover and the lower cover to each other is attached to the rear end of the engine cover. The upper cover includes a belt holding portion that holds the fixing belt. The belt holding portion includes a holding frame that forms a belt insertion hole. A head portion of the fixing belt includes a pair of contact portions that come into contact with upper surfaces of a pair of first frame portions of the holding frame.

Embodiments of a portable propulsion facilitation device and system for a marine vessel provide a rechargeable power source and a removable trolling motor mounting base securable to a marine vessel. In various embodiments, the power source employs rechargeable batteries that are secured within a cover. The device can include an access door that permits a user to access the power source when removal or replacement is necessary. The power source can be maintained within a housing of a trolling motor or one or more housings secured to the mounting base. In various embodiments, the mounting base is integrated with, or attachable to, one or more tubes, wherein the tube(s) can be secured and/or placed in a traditional fishing rod holder or other opening on the vessel. A trolling motor can be secured to the mounting base.
