A cowling for an outboard motor extends from port side to starboard side in a lateral direction. The cowling includes port and starboard inlets that direct flow of intake air into the cowling and face outwardly in the lateral direction. The cowling further comprises port and starboard duct systems. Each duct system is configured to receive and convey intake air from one of the port and starboard intake ports to an intake conduit for the outboard motor. Each duct system defines a first separation region that receives and conveys the intake air laterally outward to separate a first portion of water from the intake air. Each duct system further defines a second separation region that receives and conveys the intake air from the first separation region laterally inward to separate a second portion of water from the intake air.

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 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 foreign matter collecting device provided at a ship propulsion device that is configured to apply a propulsive force to a ship, the foreign matter collecting device includes an anti-ventilation plate extending in a horizontal direction and a collecting part provided in the anti-ventilation plate. A flow path extending from a water intake port to a water discharge port is provided in the anti-ventilation plate. A filter configured to collect fine-grained foreign matters from a water flow in the flow path is provided in the collecting part.

A method for making a marine propulsion device. The method includes providing a drive housing that extends between a first end and a second end, whereby drive housing has a cavity that extends inwardly from the second end. The method further includes positioning a conductor within the drive housing, whereby the conductor is configured to conduct power for the marine propulsion device. The method further includes inserting a motor assembly into the cavity and electrically coupling the motor assembly and the conductor while the motor assembly is positioned in the cavity and without entering the cavity via the first end of the drive housing.

An intake plenum is for a marine engine, the marine engine having first and second throttle devices for controlling flow of intake air to the marine engine. The intake plenum has an airbox providing an expansion volume, first and second inlets that convey the intake air in parallel to the expansion volume, first and second outlets that convey the intake air in parallel from the expansion volume to the first and second throttle devices, and first and second Helmholtz-style attenuator devices located at the first and second outlets, respectively. Together the first and second inlets, expansion volume, and first and second Helmholtz-style attenuator devices are configured to attenuate different frequencies of sound emanating from the marine engine via the first and second outlets.

An oil sump housing for an outboard motor of a marine vessel is provided. The oil sump housing includes an upper mounting flange including multiple upper mounting holes, a lower mounting flange including multiple lower mounting holes, and an inner housing wall and an outer housing wall extending between the upper mounting flange and the lower mounting flange. The inner housing wall defines a transmission mounting cavity, and the inner housing wall and the outer housing wall define an oil containment cavity that at least partially surrounds the transmission mounting cavity.

A mechanical joint for transferring rotational motion between shafts at an angle and related assemblies. The assemblies can include both fixed and adjustable-angle joint housings for providing high torques in hard to reach areas. Other assemblies include improvements in inboard marine drives that correct the prop angle to generally align with the direction of travel of the boat and outboard marine drives with improved drive trains.
