An improved snowmobile steering ski attaches to the steering spindles of a snowmobile and generally includes a frame and an elongated ski having a protruding keel that emerges from the bottom running surface of the ski proximal a front end and gradually increases in protrusion with respect to the bottom running surface to a point of maximum protrusion at a point on the ski runner directly below the steering spindles of the snowmobile. The keel then gradually decreases in protrusion and merges back into the bottom surface proximal a rear end of the ski runner.
