Abstract: A duct structure for a watercraft includes a flexible tube for providing an air intake for the watercraft and a flexible member for being disposed on an inner perimeter of a hole in a hull of the watercraft for holding the flexible tube. A convex portion of the flexible tube engages at least one concave portion of the flexible member around substantially the entire circumference of the flexible member, allowing for easy insertion and removal of the flexible tube from the flexible member.

Abstract: A shift control mechanism of a small watercraft for selectively shifting between a forward, a neutral and a reverse drive mode includes a first mounting bracket, a second mounting bracket, and a shift control lever having a grip for operating the shift control lever and first and second sides. The shift control lever is disposed between the first and second mounting brackets. The shift control lever is rotatably connected between the first and second mounting brackets via at least two connecting members, the shift control lever is supported on each of the first and second sides thereof by respective ones of the first and second mounting brackets, and at least one of the first and second mounting brackets is mounted on a deck of the small watercraft.

Abstract: A hinge assembly for a hatch cover of a watercraft includes a hinge arm having a substantially J-shaped configuration and made of an extruded material, a deck mounting bracket for connecting the hinge arm to a deck of the watercraft, a hatch cover mounting bracket for connecting the hinge arm to a hatch cover of the watercraft, a hinge shaft connecting the hinge arm to the deck mounting bracket, and at least one mounting member connecting the hinge arm to the hatch cover mounting bracket. The hinge arm has a width dimension extending in a longitudinal direction of the hinge shaft that is greater than a thickness dimension extending in a direction perpendicular to the longitudinal direction of the hinge shaft.
