摘要： A transmission for a counter-rotational propeller system of a watercraft outboard drive provides an increased flow area for exhaust discharge behind the transmission within the lower unit. The transmission includes a pair of counter-rotating gears. A front clutch selectively drives an inner propulsion shaft by engaging the front gear. A rear clutch selectively drive an outer propulsion shaft by engaging either of the gears. The front clutch lies forward of the front gear and the rear clutch is interposed between the gears. The clutching mechanism thus entirely lies forward of the rear gear to provide more space for exhaust discharge flow behind the transmission.

摘要： In a marine outboard engine unit driven by a four-stroke-cycle engine, the vertical crankshaft is aft of the cylinders and the camshaft and drives the camshaft via a sprocket-and-chain mechanism, the lower end of the camshaft being coupled to the extension drive shaft which is coupled to the propeller at the lower end of the lower unit, and the carburetor for each cylinder is at the forward part of the engine. By this arrangement, "oil rise" of the lubricating oil in the engine is prevented when the boat hull, under way, assumes a bow-up attitude, and the speed-reduction ratio from crankshaft to propeller can be reduced, whereby a high-speed, high-power-output engine can be used.

摘要： Disclosed herein is a marine propulsion device including a shiftable, reversing transmission located in a propulsion unit and connecting a drive shaft to a propeller shaft and a shifting mechanism including an actuating member connected to the transmission. Movement of the actuating member to shift the transmission between a neutral condition and forward drive and reverse drive conditions is effected by a shifting system including a flexible dual cable conduit assembly connected between the actuating member and a shift lever mounted for reciprocal movement. The opposite ends of the two shift cables are linked together in a manner such that the movement of the shift lever in opposite directions causes alternate pulling of the shift cables to shift the transmission.

摘要： A transmission system for a counter-rotational propulsion device is easily incorporated into an existing outboard drive of a watercraft to convert the outboard drive from a single propeller drive to a counter-rotational dual propeller system. The transmission system involves a first transmission which selectively couples an inner propulsion shaft with an existing drive shaft of the outboard drive. The inner propulsion shaft in turn drives a rear propeller. A second transmission of the transmission system is provided between the inner propulsion shaft and an outer propulsion shaft. The second transmission reverses the rotational drive direction input by the inner propulsion shaft so as to drive the outer propulsion shaft in an opposite rotational direction. The outer propulsion shaft drives a front propeller which spins in an opposite direction to that of the rear propeller, but asserts a thrust in the same direction as the rear propeller.

摘要： A bevel gear transmission for a marine outboard drive having hydraulically actuated clutches for selectively coupling oppositely rotating bevel gears to a shaft to affect either forward or reverse drive. The bevel gears are each supported on the shaft by thrust bearings and are on the outer sides of the bevel gears and are urged into engagement with the thrust bearings by coil compression springs that also act to release the respective clutches. As a result of this arrangement, a constant lash is maintained between the bevel gears regardless of whether they are transmitting a driving thrust or not.

摘要： The present invention provides an improved throttle opening control device for a marine propulsion arrangement. The invention allows an operator of a marine propulsion unit to shift from a forward or reverse operating state into neutral, in order to start or restart an engine, or to effect an urgent transmission shift change during operation, without having to execute an independent step of separately reducing the throttle opening beforehand. According to the present invention, the angle of throttle opening is automatically controlled by an interconnection to the transmission shifting system of the propulsion arrangement.

摘要： A twin outboard drive and more particularly to an improved transmission and shifting arrangement for such drives. The drives include forward, neutral and reverse transmissions of the bevel gear type and which provide counter-rotation of the respective associated propellers. One of the transmissions is shifted in one direction to shift from neutral to forward while the other transmission is shifted in the opposite direction to shift from neutral to forward. A pair of remote control shift levers are provided and a motion transmitting means connects the shift levers with the transmissions so that the transmissions are shifted in opposite directions when the shift levers are moved in the same direction. In some embodiments, this is accomplished by a crank and follower mechanism and in other embodiments, it is accomplished by a cam and follower arrangement.

摘要： An outboard engine with an automatic clutch to be used for a fishing boat arranged between the crankshaft of the engine and the propeller driving shaft. The automatic clutch comprises a main centrifugal clutch mechanism which is to be engaged at a revolutional torque close to the rated revolution of the engine and an auxiliary centrifugal clutch mechanism which transmits the torque between the shafts with a frictional slip at a revolutional torque which is produced at a rate lower than the above mentioned one. For operating at a higher speed, the propeller is driven by the transmitted revolutional torque through the said main centrifugal clutch mechanism while for sailing at a slower speed or at trolling, it is driven by the torque which is reduced in transmission by the slip effect in the auxiliary centrifugal clutch mechanism.
