To enhance the joint strength between the hull and the deck of a water craft and reduce the number of steps needed for joining the hull and the deck, a water craft body is constructed by joining the hull and the deck together at their peripheral regions, applying a protector strip of extruded material to the joint between the hull and the deck peripherally of the water craft body and installing fasteners, such as self-tapping screws or rivets, through the protector strip and through the peripher...

Improvement in a small pump having the usual impeller, shaft, motor and housing characterized by a plurality of elongate housing sections that conformingly fit together laterally in an assembled condition to form the housing. The improved pump has a clamp ring serving as a portion of a means for joining and holding the housing sections together in the assembled condition; and a shroud for covering the motor for protection against droplets of spray. Also disclosed are specific structural features...

Disclosed is a small watercraft having an engine cooling system which can lessen a temperature distribution of an engine. The small watercraft comprises an engine for driving a propulsion unit of the watercraft, and the engine includes a first cooling passage formed inside a cylinder head of the engine, for cooling the cylinder head with a coolant flowing therethrough, and a second cooling passage formed inside a cylinder block of the engine, for cooling the cylinder block of the engine with a c...

A small watercraft has a hull formed such that the center of buoyancy is slightly aft of the structural center measured in the longitudinal direction of the hull. The craft is equipped with an engine mounted near the center of buoyancy within the hull, and has such auxiliary parts as an oil tank and a muffler which are arranged around the engine. The upper portion of the wall surrounding the engine compartment for the engine may be constructed to protrude upwardly, and a hood with a seat may be ...

A small boat comprising a helmseat positioned at the center of the forward half of the boat, and a control stick for steering the boat positioned at the front of this helmseat. Since the helmseat is positioned at the center of the forward half of the boat, the driver is located approximately equidistant from the left and right gunwales, which makes it easier to steer the boat. In addition, a control stick is positioned to the front of the helmseat, and, because this control stick can be used to ...

An improved fuel delivery and injection system for a small watercraft engine reduces the heat effects within an enclosed engine compartment upon various components of the engine and upon the fuel within the fuel system. The fuel system integrates a fuel pump within a fuel tank at a location which minimizes the effects of watercraft leaning. The inlet of the fuel pump desirably corresponds, in the lateral direction, with a position of an inlet to the jet pump unit. In this position, the pump is l...

A small watercraft equipped with a lock mechanism for an engine hood is disclosed. The watercraft includes a deck, an engine hood that is pivotably provided to the deck around a pivot shaft, and covers an engine room thereunder from above so as to open and close, and a lock mechanism for locking the hood in an open position. The mechanism includes one member attached to the hood, another member attached to the deck, and a stopping member. At least one of the one member and the another member is ...

A small fan with an electric power motor is provided, the rotor of which is designed as a cup-shaped outer rotor and blade wheel hub. The outer wall of the blade wheel hub coaxially widens in the direction of air flow and forms the inner wall of an air flow duct. The fan blades are mounted on this outer wall, which wall, is conical shaped and is disposed as an outer lining over the cup-shaped outer rotor.

The invention relates to small container (2.1, 2.2), in particular of plastic, including at least one cylindrical, in particular circular cylindrical section with a means (16.1a to c, 16.2a and b, 18.2a and b) located in the region of cylindrical peripheral area of this section for producing a form-locked slide-insertion-connection with at least one further such small container. The invention is characterized in that the container is rollable in the peripheral direction perpendicular to the inse...

A small watercraft is provided. The small watercraft comprises a hull formed to have a substantially uniform thickness by using reinforced fibers impregnated with resin. The hull includes a curved portion formed by protruding outward and curving a part of the hull, and a filling material filled in a groove portion on an inner side of the hull which is created by forming the curved portion.
