One of these driven gears 15 (right) has a hollow shank 16 facing the propeller right rotation 17 (Fig. 1) mounted on the end of the propeller shaft 14 extending beyond the housing 4 of the gearbox 3. Another driven gear 18 (left) (Fig. 2) has a hollow shaft 19 is turned in the direction opposite to the propeller screw right rotation 17. Between 15 and right left 18 slave gear reducer 3 posted by clutch 20. To move the clutch 20 is an arm 21, which is connected with the main thrust of 11. The coupler 20 has projections 22 for engagement with the left driven gear 18.

Outboard motor equipped with a propeller screw left rotation 23 (Fig. 1) mounted on the hollow shaft 16 (Fig. 2) the right driven gear 15, which is made the 0 posted by thrust bearing 24.

Reversible node 5 contains (Fig. 3) the main pinion gear 25 on a shaft 26 which (upper shank) facing the engine 1 is mounted the lower end of the torsion of the drive shaft 9 and the shank 27 (low shank) facing the gear 3, a slider 28 to enable the forward stroke by engagement with the leading shaft gear 13 of the gear 3. The major, leading gear 25 of the reversing node 5 is in constant mesh with the driven gear 29 of the reversing node 5, with the shank 30 facing the gearbox 3, similar to the slider 31 to reverse gear by meshing with the gear 32 mounted coaxially with said driven gear 29 of the reversing node 5. The gear 32 is installed with the possibility of free rotation and is connected with a chain 33 with a gear 34 mounted on the leading end shaft-gear 13 of the gear 3. Between the bars 28 and 31 is an arm 35 to alternately activate the front and rear. In Fig. 4 shows the reverse node 5 in positions including 1st speed reverse.

The hollow shaft 16 (Fig. 2) the right driven gear 15 gear 3 is located in the needle bearings 36, and the output from the housing 4 reductiou 18) gear 3 posted by washer 38 to regulate the reliability of the engagement of these gears with the leading shaft gear 13 of the gear 3.

The hollow shank 16 of the right driven gear 15 gear 3 has openings 39 to lubricate propeller shaft 14 located inside the hollow shank 16.

On the housing 2 (Fig. 1) of the engine 1 has a handle 40 for starting the engine 1. In the lower part of the housing 2 (Fig. 1, 5) is fixed to two brackets 41, 42 with slots respectively 43, 44. In the slot 43 of the strap 41 includes a finger 45 main thrust 11, and the slot 44 of the strap 42 includes a finger 46 thrust 12 enable reversing of the node 5. To enable the 2nd speed forward and one reverse gears serves as the handle 47, and to enable the 1st speed forward running and reverse arm 48.

Works outboard motor as follows. With help of suspension 7 (Fig. 1) fixed on the side of the boat (not shown). The start of the engine 1 is performed by the pull handle 40. The rotation of the output shaft 10 of the engine is transmitted to the torsion drive shaft 9 located in deadwood and impaled on the top of the shank 26 of the main driving gear 25 of the reversing node 5 (Fig. 3) located in the housing 6.

The inclusion of the first speed forward stroke is performed by moving the arm 48 in the direction of the housing 2 of the engine 1 (Fig.5) the finger 46 thrust 12 enable reversible node 5, in PR the second side of the rocker arm 35 lowers the slider 28 to enable the forward stroke, mounted on the lower shank 27 of the main driving gear 25, to engage with the leading shaft gear 13 of the gear 3, which is located in the housing 4 (Fig. 2). Thus rotation of the torsion shaft 9 (Fig. 1), the lower end of which is mounted on the upper shaft 26 (Fig. 3) the main driving gear 25 of the reversing node 5, is passed on to the pinion shaft 13 of the gearbox 3 (Fig. 2), which transmits the rotation of the right driven gear 15, the hollow shank 16 which is fixed propeller left rotation 13. The rotational motion of the output shaft 10 of the engine 1 (Fig. 1) is converted into rotational motion of the propeller left rotation 23 and the boat moves forward with the 1st speed. The hollow shank 16 of the right driven gear 15 gear 3 rotates inside the needle (roller) bearings 36 (Fig. 2). The thrust bearing 24 assumes the axial force developed during operation of the propeller 23, directed forward, in the direction of boat movement. Through holes 39, made in the hollow shank 16 of the right driven gear 15, is supplied grease on the propeller shaft 14 passing inside of the shank 16. Reliability gearing right 15 left and 18 driven gears of the gearbox 3 regulate washers 38. The tightness of the reducer the pressure of the second speed forward course it is necessary to move the handle 47 (Fig. 5) in the direction of the housing 2 of the engine 1. When the finger 45 main thrust 11 (Fig. 3) located in the slots 43 of the strap 41, under the action of the resultant forces will raise the main rod 11 and through one end of the rocker arm 21 (Fig. 2). Revolving around its axis, the rocker arm 21 and the other end pushes the clutch 20 with projections 22, in the direction of the left driven gear 18 gear 3 to gear with her. The left driven gear 18 gear engages the propeller shaft 14, since the hollow shank 19 of this gear is mounted on the end of the propeller shaft 14 opposite the end on which is fixed propeller right rotation 17. Thus, rotation of the output shaft 10 of the engine 1 is transmitted to the propeller shaft 14. The second speed is enabled. To turn off the first and the second speed of the arm 47, 48 returns to its original position, and all the elements involved in the transmission of the rotation from the output shaft 10 of the engine 1 at the propellers right 17 and 23 left rotation, return to the initial position (neutral).

When enabled, the second speed forward course works both propeller. Propeller left rotation 23 converts the circulating water flow in the axial, directing it in the direction of the propeller right is reset slippage, resulting in a significant increase in efficiency and reduction of power losses.

The inclusion of the first speed reverse carry handle 48 from the housing 2 of the engine 1 (Fig. 5). When this finger 46 thrust 12 enable reverse site 5, located in the slots 44 of the strap 42, under the action of resultant forces lowers cravings 12 enable reversing of the node 5 and the other side of the rocker arm 35 (Fig. 3, 4) associated with the slider 31 to reverse gear located on the shaft 30 driven gear 29 of the reversing node 5. The slider 31 reverse gear is engaged with the gear 32 mounted coaxially with the driven gear 29 of the reversing node 5 and connected with a chain 33 with a gear 34 mounted on the leading end shaft-gear 13 of the gear 3. The direction of rotation of the leading shaft gear 13 of the gear 3 (Fig. 2) and the right driven gear 15 gear 3, the hollow shank 16 which is mounted a propeller left rotation 23, changed to the opposite. Back (1st speed) is enabled.

To enable the 2nd speed reverse, you must move the lever 47 in the direction of the housing 2 of the engine 1. When the finger 45 main thrust 11 (Fig. 5) located in the slots 43 of the strap 41, under near the camping around its axis, the other end pushes the clutch 20 with projections 22, in the direction of the left driven gear 18 gear 3 to gear with her. The rotation is transmitted to the propeller shaft 14, which is fixed to the screw and the right rotation 17. The second rear speed enabled.

When enabled, the second speed reverse running simultaneously two propeller: propeller right rotation 17 and the screw and the left rotation 23. Propeller left rotation 23 perceives axial flow directed in his direction rowing screw right rotation 17. This increases the water pressure in the work area of the propeller left rotation 23 and reduces slippage between the blades. Thus, when reverse gear is engaged also increasing efficiency and reducing power losses.
