20080153367 - Internal elastomer damper for vehicular propeller shafts: Ringing noise in a tube or in tubes comprising a propeller shaft of an automotive drive is attenuated by an elastomeric ring positioned in each shaft. The elastomeric ring is a split ring, preferably made of recycled rubber, wherein the ring normally has a rectangular shape and is bent into... Agent: General Motors Corporation Legal Staff

20080146095 - Outboard motor: An outboard motor has a construction in which the area of an exhaust passage can be secured easily and exhaust noise is less likely to escape into the air, allowing the exhaust noise to be lowered. The outboard motor includes a lower case, a propeller shaft rotatably supported in the... Agent: Yamaha Hatsudoki Kabushiki Kaisha C/o Keating & Bennett, LLP

20080146096 - Watercraft swivel drives: Enhanced watercraft performance is provided by combinations of one or more inboard swivel propulsion drives and hull tunnels. A tunnel at the hull centerline with specific features provides performance advantages for a center swivel propulsion drive. Use of front propeller based traction propulsion is particularly advantageous in the swivel drive... Agent: Volvo Corporate Patents

20080146097 - Propeller thrust transmission device for a watercraft propulsion device: A propeller thrust transmission device for a watercraft propulsion device prevents an occurrence of a precession of a spacer on an entire circumference around a taper part if a water resistance force acts upward on a propeller. The propeller thrust transmission device includes a taper part of an outer shaft... Agent: Yamaha Hatsudoki Kabushiki Kaisha C/o Keating & Bennett, LLP

20080146098 - Sealing structure of outboard motor: A sealing structure of an outboard motor comprises: a bottom cowling 11 covering a lower part of an engine 102; a top cowling 12 covering an upper part of the engine 102; and a sealing material 30 through which said top cowling 12 is attached to said bottom cowling 11,...
