摘要： The reverser (1) is of the type wherein the reversing devices are contained in the leg itself, and comprises two clutches (18, 19) which draw their motion directly from the drive shaft (7). The clutches (18, 19) each act alternately on a driven gear (30) which actuates the propeller shaft (29). Each of the clutches (18, 19) has a hydraulic engagement piston (12, 13). The two hydraulic pistons (12, 13) are fed by a pump (32) keyed on the drive shaft (7) and contained in the body (2) of the aft foot. A hydraulic circuit connects the pump (32) to the pistons (12, 13) through a distributor. The hydraulic circuit is also employed for lubricating all the moving parts of the power leg.

摘要： A marine drive unit (1) includes a lower torpedo housing (9). At least one propeller shaft (21) is mounted in the housing for rotation about a drive axis (17). The propeller shaft is driven by a driving gear (16) suitably connected to a marine engine (4) and mounted on the drive axis. A first forward thrust bearing (41) is disposed between the driving gear and the housing. In addition, a second forward thrust bearing (42) is disposed adjacent the forward end of the propeller shaft. A pre-loading device, in the present embodiment a washer-like Belleville spring (43) of a desired capacity, is disposed to provide an adjustable rearwardly biasing force on the second thrust bearing.

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.
