    Abstract: Embodiments include a snowmobile comprising a frame and an engine, the engine including a crankcase mounted to the frame with a crankshaft axis of rotation positioned perpendicular to a longitudinal centerline of the frame. The crankcase includes a cast lower surface comprising a first structural wall extending substantially perpendicular to the longitudinal centerline and a second structural wall extending substantially perpendicular to the longitudinal centerline. The lower cast surface further includes a panel extending between the first structural wall and the second structural wall, the panel defining a curved surface and a mounting surface extending from the first structural wall and across at least a first portion of the panel. The snowmobile further comprises an engine mount connected to the frame comprising a housing and a damper. The housing is secured to the mounting surface with a first fastener that extends into the first structural wall to position the damper opposite the panel, and the engine mount is positioned below the engine.
