Patent number: 8944868Abstract: An outboard motor attached to a hull includes a body, a body driving device, and a control device. The body includes an engine and a propeller shaft. The propeller shaft is configured to be rotated by a drive force from the engine. The body is configured to pivot about a tilt axis extending in a lateral direction of the hull. The body driving device is configured to drive the body about the tilt axis. The control device is programmed to control the body driving device so that a rear end of the propeller shaft is positioned higher than a front end of the propeller shaft when the control device determines that the propeller shaft is to rotate in a direction in which the hull is propelled in reverse.Type: GrantFiled: May 8, 2013Date of Patent: February 3, 2015Assignee: Yamaha Hatsudoki Kabushiki KaishaInventor: Isao Kanno

Patent number: 8932093Abstract: In an outboard motor, a first damper member is disposed between a bracket and a casing such that the first damper member supports a weight of an outboard motor body. A second damper member is disposed between the bracket and the casing. The casing or the bracket includes a left first inclined surface and a right first inclined surface. The left first inclined surface and the right first inclined surface are inclined with respect to a front-back direction of the outboard motor body in a planar view of the outboard motor body. The second damper member includes a left second inclined surface and a right second inclined surface. The left second inclined surface is arranged to oppose the left first inclined surface. The right second inclined surface is arranged to oppose the right first inclined surface.Type: GrantFiled: March 7, 2013Date of Patent: January 13, 2015Assignee: Yamaha Hatsudoki Kabushiki KaishaInventor: Tomohiro Hagi

Patent number: 8905801Abstract: A marine outboard motor comprises first and second cylinder blocks connected to a crankcase having a crankshaft. Each cylinder block contains a cylinder having a cylinder central axis, and a piston reciprocally mounted within the cylinder. First and second planes are defined by the first and second cylinder central axis and the crankshaft axis. The first and second planes are at a first angle less than 120 degrees. The exhaust manifold is at least in part within a valley formed between the first and second cylinder blocks. A configuration with a third cylinder block opposite to the first and second cylinder blocks is also described. A third plane is defined by a third cylinder central axis and the crankshaft axis. The third plane is at a second angle to the first plane and at a third angle to the second plane. The second and third angle can be equal.Type: GrantFiled: March 26, 2010Date of Patent: December 9, 2014Assignee: BRP US Inc.Inventor: Todd D. Craft
