The edge portion overlaps an outer surface or edge of the polymeric sheet in finished condition.

Abstract: A paper tube of a propeller tube 12 is made by winding a single faced corrugated fiberboard 16 in which a wavy corrugating medium 16b is fixed to one side of a flat linerboard 16a so that the corrugating medium 16b is oriented outwards, and the corrugating medium 16b contacts with an inner surface of the propeller tube 12, so as to enhance a vibration controlling function. When winding the single faced corrugated fiberboard 16, since the single faced corrugated fiberboard 16 cannot be wound in a direction oblique to a direction of ridges of the corrugating medium 16b, there are no fears that the shape of the single faced corrugated fiberboard 16 is collapsed to taper axially, thereby it becomes possible to prevent a reduction in vibration controlling function that would otherwise be caused due to a change in the shape of the paper tube.

Abstract: A forward and reverse drive switching device for an outboard motor can include a switching mechanism that is actuated so as to set a propeller to a forward drive mode or a reverse drive mode.

Abstract: Personal watercraft systems are described. The personal watercraft systems include a housing for supporting a water jet engine system. The housing has a pickle fork shaped hull for operation enjoyment. A pair of sponsons is removably attachable to the housing to facilitate breakdown of the watercraft system assembly into more easily transportable components. A cowling is disposed in the housing about the water jet engine system for forming a water jacket about the engine. A support is attached to the housing to support a torso area of an operator. A seal is disposed between the support and the housing for sealing the interface therebetween and absorbing impacts. A steering mechanism is connected to the personal watercraft system for allowing an operator to control the personal watercraft systems direction of travel. The steering mechanism is located below the support for preventing inadvertent operator contact therewith.
