ABSTRACT:
An outboard motor comprising a mounting assembly adapted to be fixedly attached to the transom of a boat and including a cylindrical bore defining a steering axis, a propulsion unit including a rotatably mounted propeller, a power head drivingly connected to the propeller, and a steering arm shaft pivotally received in the bore in the mounting assembly for pivotal movement of the propulsion unit relative to the mounting assembly and to the transom about the steering axis, and a friction device mounted on the mounting assembly and frictionally engaging the steering arm shaft for damping oscillation of the steering arm shaft about the steering axis relative to the mounting assembly.
