  • Patent number: 5741165
    Abstract: A number of embodiments of outboard drive systems that include a combined vertically extending drive shaft driven by the propulsion unit and which drives a generally horizontally extending propeller shaft that drives a propeller positioned substantially rearwardly of the transom. The propulsion system is supported for steering and trim movement about respective spaced apart axes and these axes are both disposed substantially below the transom of the associated watercraft. The propeller driven by the propeller shaft is disposed further from the trim axis than the forward end of a tiller that is affixed to the outboard drive for affecting the steering and trim movement.
