Abstract: An impeller assembly for a snowthrower includes a driven shaft configured to rotate about an axis, a flexible impeller configured to rotate about the axis and extending horizontally across substantially a complete width of the impeller assembly parallel to the axis, and a rigid cutting implement. The flexible impeller extends radially from the driven shaft to an impeller radial distance. The rigid cutting implement extends radially from the driven shaft to a cutting implement radial distance less than the impeller radial distance, wherein the rigid cutting implement is spaced apart from and does not contact the flexible impeller.

Abstract: An impeller assembly for a snowthrower includes a driven shaft configured to rotate about an axis, a flexible impeller paddle coupled to the driven shaft for rotation about the axis, and a rigid cutting implement coupled to the driven shaft for rotation about the axis. The flexible impeller paddle is configured to clear snow from a surface to be cleared. The flexible impeller paddle extends radially from the axis to a paddle radial distance. The rigid cutting implement is configured to break up snow or ice on the surface to be cleared. The rigid cutting implement extends radially from the axis to a cutting implement radial distance less than the paddle radial distance.

Abstract: A locking mechanism for an outboard motor is provided which prevents a moveable segment of the outboard motor from rotating about a steering axis relative to a stationary segment of the outboard motor. A slidable rod is disposed within a tilt tube of the outboard motor and is connected by a connecting link to the moveable segment of the outboard motor. If a locking device, such as a pin, is inserted through holes in the tilt tube and the rod, relative movement of the tilt tube and the rod can be prevented. If this relative movement is prevented, the moveable segment of the outboard motor is locked in position relative to the stationary segment of the outboard motor to which the tilt tube is attached.
