摘要： An example watercraft includes a hull that defines a cockpit. A scupper is provided that extends from the cockpit through an exterior surface of the hull. A recess defined by the hull is in communication with the scupper, and the recess defines a portion of a venturi tube. A plate that is attachable to the hull is configured to define another portion of the venturi tube such that when the plate is attached to the hull, a complete venturi tube is defined.

摘要： A water propulsion assembly operatively connected to a watercraft moving on or through a body of water, may produce a propulsive force by sweeping fins in an oscillating motion in a generally transverse direction relative to a longitudinal axis of the watercraft. The fins may be rotatable about a first axis coplanar to the center longitudinal axis of the watercraft. Drive members rotatable about a second axis that is canted relative to the first axis may be operatively connected to the fins. The oscillatory motion of the fins may be controlled by torque applied at the canted second axis by reciprocating the drive members in a plane generally parallel to the center longitudinal axis of the watercraft. The oscillating fins may provide a propulsive force during both oscillating directions of the fins as they sweep back and forth.

摘要： A marine vessel engine in which moving parts found in conventional marine engines are eliminated, wherein such engine is used for the propulsion of marine vessels. In the marine vessel engine, no lubrication or cooling is required, and a column of water replaces the conventional piston in a cylinder of the engine, wherein such water column partially fills such cylinder. The marine vessel engine comprises a cylinder, a bent tube with a plurality of openings and two ends, a flapping member, at least one solenoid valve, and an exhaust. In operation of the marine vessel engine, a column of water fills the cylinder through the bent tube openings, and is purged outside from the cylinder through the flapping member. The at least one solenoid valve controls the flow of a power source into the cylinder.

摘要： A guard for protecting wildlife is mounted on an outboard motor having a propeller and keel below an anti-ventilation plate. The guard has a spaced pair of bars each with an upper section, a lower section and between them a midsection. The upper sections of the bars can be attached to opposite sides of the anti-ventilation plate in order to position the lower sections below the propeller and keel. The lower sections have a smooth, projection-free streamline for avoiding snagging on sea weed.
