A method and apparatus for limiting the torque from an engine to the drive train of a watercraft. A first output voltage is produced based on the digital data value stored in the register. In some embodiments, the polyurethane block copolymers can be used as compatibilizing agents, which can be used, for example, in polymer blends, polymer alloys, solutions, emulsions, as well as in extruded and injection molded articles. In embodiments of the present invention, the iterative process is repeated until the costs of a plurality of items of the plurality of cost groups have been calculated. The clipboard manager further allows the user to identify a paste location in the document that is to be edited.
