An electromotive drive device for a floatable device includes an electric motor operable by means of a separate power supply module with an energy accumulator, an electronic open-loop/closed-loop control unit and a remote control. The electric motor is within a housing connected to a drive propeller, which at least partially is surrounded by a protective device connected to the housing via connecting supports. The housing has an upper housing part and a lower housing part connected to each other by at least one releasable connection. The housing includes an elliptical bow, the end thereof transitioning into an essentially circular diameter with relative dimensions being a sum larger than an end of the housing with a projection opposite the bow. The housing in the lateral area behind the diameter is provided with intake openings for cooling water to flow inward. The cooling water can exit via outlet openings provided in the connecting supports. An operating method for the drive device includes an electronic open-loop/closed-loop control unit with an information processing unit. The drive ensures energetic use of the power supply module by reducing power while considering a travelled distance or travel time of the floatable device.

An engine enclosure for containing a gas turbine engine is provided. An exemplary engine enclosure includes features that improve noise and thermal attenuation, reduce the weight of the enclosure, and provide for more accessible access points to the interior volume of the engine enclosure.

A watercraft and a waterproof electronics container are provided. The watercraft includes a flotation portion. A strut is removably affixed to a portion of the watercraft. A first connector portion is mounted to the upper end of the strut. A waterproof electronics container includes a second connector portion is disposed such that the second connector forms at least one electrically conductive pathway with the first connector portion when both are affixed to the watercraft. The waterproof electronics container is removably affixed to the said watercraft. In one aspect, the waterproof electronics container houses a power source capable of powering an electric motor that propels the watercraft.

A protective motor cover assembly includes a cylinder that is positionable over an outboard boat motor. The cylinder is comprised of a resiliently stretchable material to conform to contours of the outboard boat motor. The cylinder is comprised of an opaque material to protect the outboard boat motor from sunlight. Indicia are printed thereon on the cylinder to enhance the ornamental appearance of the outboard boat motor. A drawstring is slidably integrated into the cylinder. The drawstring closes the cylinder around the outboard boat motor when the drawstring is tightened for retaining the cylinder around the outboard boat motor.

A marine drive includes an engine; a cowl having first and second cowl portions. The first cowl portion is movable with respect to the second cowl portion into an open position in which the engine is manually accessible and a closed position in which the engine is enclosed; and a rigging port in the second cowl portion. The rigging port provides a passageway for rigging connectors extending from the engine to a component located remotely from the engine. A rigging opening provides manual access to the rigging connectors and the engine, including when the first cowl portion is in the closed position. A removable access door covers the rigging opening and prevents manual access to the engine and rigging connectors via the rigging opening. The removable access door is fastened to the second cowl portion by a removable fastener that is hidden from view.
