摘要： A two pathway exhaust and water discharge through-hull system is coupled to a muffler for separating exhaust gases and cooling water at operating speeds such that at low engine speeds exhaust gases and water are discharged through a first outlet preferably above the waterline and, when the engine speed is increased above a predetermined level, exhaust gases are discharged through a second outlet which communicates with a streamlined, low back-pressure underwater discharge skeg and water is discharged through the first outlet. In a preferred embodiment of the invention, a discharge skeg is positioned at each comer of the transom for a twin engined vessel. In a preferred embodiment also, each of the underwater discharge skegs is mounted to the bottom of the hull and includes a mounting flange and an upwardly extending collar which extends through the hull and is coupled to an adapter for coupling the discharge skeg to an exhaust outlet of a muffler. As a result, an exhaust system is provided which is efficient, quite and which discharges exhaust gases underwater and away from the vessel when underway at normal operating speeds.

The exhaust valve is positioned in an exhaust port of an engine and movable between a retracted position in which the exhaust flow timing is advanced, and an extended position into the port in which the exhaust flow timing is retarded. A control is provided for moving the valve in a cleaning operation after the engine is started and running above a predetermined low speed. The cleaning operation may additionally be performed when the engine is shut off.

摘要： An improved exhaust probe arrangement within an exhaust system of a small watercraft increases the accuracy of the probe's readings. The aperture is located upstream of a point where cooling water is introduced into the exhaust system for silencing purposes. As a result, the ingress and egress of exhaust gases flow into and out of the aperture is generally unimpeded by the cooling water. The tendency of water to enter and clog the aperture is also reduced. The precision of the exhaust probe measurements consequently is greatly increased.

摘要： An improved catalytic exhaust system for a watercraft provides two stage treatment of exhaust gases before expulsion from the watercraft. The catalytic exhaust system also is configured to minimize the restriction the catalysts pose to exhaust gas flow through the exhaust system so as to reduce engine back pressure and improve engine performance. A catalytic device of the exhaust system includes a pre catalyst and a main catalyst positioned downstream from the pre catalyst. The pre catalyst can take the from of a catalytic material coating along a portion of the exhaust flow path and the main catalyst can be a catalyst bed. The exhaust gas flow path through the exhaust system also smoothly tapers into and out of the main catalyst so as to reduce the degree of flow resistance through the main catalyst.

摘要： A propeller for a marine propulsion system that provides variable length exhaust paths depending upon the speed of the boat and motor. The propeller includes a propeller hub and an exhaust tube positioned within the propeller hub. The exhaust tube extends past the aft end of the propeller hub and defines a first exhaust passageway. A second exhaust passageway is positioned between the propeller hub and the exhaust tube. The second exhaust passageway is shorter than the first exhaust passageway. At low speeds, engine exhaust exits the longer first passageway, while at moderate speeds, engine exhaust exits the shorter second passageway. Therefore, the effective length of the exhaust path varies depending upon the speed of the motor, such that the length of the exhaust path is specifically tuned to several speeds of the motor.
摘要翻译：一种用于船用推进系统的螺旋桨，其根据船和马达的速度提供可变长度的排气路径。螺旋桨包括位于螺旋桨毂内的螺旋桨毂和排气管。排气管延伸穿过螺旋桨毂的后端并限定第一排气通道。第二排气通道位于螺旋桨毂和排气管之间。第二排气通道比第一排气通道短。在低速时，发动机排气出口较长的第一通道，而在适度的速度下，发动机排气口离开较短的第二通道。因此，排气路径的有效长度根据电动机的速度而变化，使得排气路径的长度被特别地调整到电动机的几个速度。

摘要： A method and apparatus for preventing exhaust fumes from entering the deck area of a motor boat having an engine of the type which has an exhaust port that expels fumes at the rear end of the boat is disclosed. The present invention includes an air manifold located at the rear end of the boat above the exhaust port and adapted to direct air to the rear of the boat. Air ducts having inlets located forwardly of the rear end of the boat are connected to the air manifold. The air manifold assembly is configured to form an air barrier between exhaust fumes and the rear deck area of the boat to prevent exhaust fumes from flowing into the rear deck or the cabin area.

摘要： An exhaust system for an marine drive discharges exhaust gases between front and rear propellers of a counter-rotating propeller system. The discharge of exhaust gases between the propellers produces a cavitation effect about the rear propeller when accelerating from low speeds. As a result, the drive of the propellers accelerates more rapidly. At high speeds, however, the velocity of the exhaust gases carries the gases over the rear propeller principally in the vicinity of the rear propeller hub. No substantial cavitation effect occurs about the blades of the rear propeller at high speeds. As a result, the discharge of exhaust gases between the propellers causes no significant loss of propulsion efficiency when traveling at high speeds.
摘要翻译：用于船用驱动器的排气系统在反向旋转螺旋桨系统的前后螺旋桨之间排放废气。当从低速加速时，螺旋桨之间的废气排出会对后螺旋桨产生气穴效应。结果，螺旋桨的驱动更快地加速。然而，在高速度下，废气的速度主要在后部螺旋桨轮毂附近将后面的螺旋桨上的气体携带。在后方螺旋桨的叶片高速度下不会出现实质的气穴效应。因此，在高速行驶时，螺旋桨之间的废气排放不会导致推进效率的显着损失。
