  • Patent number: 7172476
    Abstract: An outboard motor includes a drive unit and a bracket assembly mounting the drive unit on an associated watercraft. The bracket assembly includes a swivel bracket that carries the drive unit for pivotal movement about a steering axis that extends generally vertically, and a clamping bracket that supports the swivel bracket and the drive unit for pivotal movement about a tilt axis that extends generally horizontally. Either the swivel bracket or the clamping bracket, at least in part, has a first flange, a second flange spaced apart from the first flange, and a web that extends between the first and second flanges to connect together the first and second flanges. The first and second flanges extend generally parallel to the tilt axis. The web extend generally normal to the tilt axis.
