ABSTRACT:
Herein is disclosed a snowmobile with an improved center of gravity. The snowmobile utilizes an oil pan with a bottom portion and a set of side portions that cooperate with the bottom portion to form a sump in which oil collects. The bottom portion may be grooved to permit a steering shaft to pass through the groove, thereby extending from one side of the oil pan to the other side. Optionally the bottom portion is formed to be congruous with a surface of a mechanism, such as a steering shaft, positioned at least partially beneath the oil pan. Furthermore, the oil pan may have a reduced depth.
