摘要：A driveshaft supporting structure for a watercraft is provided that supports in a substantially watertight manner at least a portion of a driveshaft. The extends from an engine, which is disposed within an inner section of a hull of the watercraft (e.g., an engine compartment), to a propulsion unit that is disposed outside the inner section of the hull. The driveshaft supporting structure includes a bearing part that is mounted on a peripheral surface of the driveshaft at a location within the inner section of the hull. An elastic part is mounted on a peripheral surface of the bearing part and a bearing part supporting section supports a press-fitted assembly of the elastic part and the bearing part. The bearing part supporting section is attached to a wall of the hull (e.g., a duct wall) at a location where the driveshaft extends from the inner section of the hull.
