An outboard motor embodying an improved throttle and trim tab control mechanism. A trim tab is pivotally supported by the outboard motor for assisting in its steering operation. The trim tab is operated by means of a pair of flexible transmitters that are affixed, at their upper ends, to extend in a generally longitudinal direction and which are operated from a drum by means of a lost motion connection that is operative in response to movement of the steering lever relative to the outboard motor. The steering lever is further supported for rotation and is operatively connected to the engine throttle for controlling its throttle in response to rotation of the control lever.

In a steering arrangement for a marine outboard drive adapted to be affixed to the transom of an associated watercraft for steering movement about a generally vertically extending steering axis and carrying driven propulsion means at its lower end, a trim tab pivotally carried by said outboard drive

In a steering arrangement for a marine outboard drive adapted to be affixed to the transom of an associated watercraft for steering movement about a generally vertically extending steering axis and carrying driven propulsion means at its lower end, a trim tab pivotally carried by said outboard drive about an axis parallel to and rearwardly of said steering axis and adapted to be submerged in operation, and a steering lever extending forwardly from said outboard drive from said steering axis in a longitudinal direction and operably connected to said outboard drive for controlling steering movement about said steering axis, the improvement comprising means for pivoting said trim tab about its pivotal axis in a direction in response to steering movement of said steering lever in an opposite direction for generating a hydrodynamic force from said trim tab upon said outboard drive tending to steer said outboard drive in the direction of movement of said steering lever comprising a pair of flexible transmitters each affixed at one end to opposite sides of the steering lever forwardly of said steering axis and each having a portion extending from its point of operative connection longitudinally relative to the outboard drive to said steering axis, said steering lever being connected to said outboard drive by means including a lost motion connection defining a pivotal axis for said steering lever, a drum fixed relative to the outboard motor and supported for pivotal movement about a drum axis parallel to the pivotal axis of the steering lever and the axis of pivotal movement of the trim tab and means for rotating said drum about said drum axis upon relative movement of the steering lever relative to the outboard drive as afforded by the lost motion connection.
