摘要： A marine propeller (10) with an adjustable exhaust structure is disclosed. Each adjustable exhaust device (30) of the adjustable exhaust structure includes an exhaust hole unit (40) with exhaust through holes (46) cut through the outer surface (226) and inner surface (228) of the propeller hub (22) of the marine propeller (10), an adjustment member (50) with shielding portions (548) mounted in the exhaust hole unit (40), and a fastening member (60) for securing the adjustment member (50) in position. The adjustment member (50) is movable to adjust the shielding area of the shielding portions (548) relative to the exhaust through holes (46) when disengaged from the constraint of the fastening member (60). Thus, the exhaust volume is adjustable to fit different conditions without changing any component parts of the marine propeller (10), facilitating ease of use of the marine propeller (10).

摘要： An electric outboard drive (20) adapted to be mounted on a transom (12) of a boat (10) through a mounting bracket (40) includes a driving device (30) and a propelling device (50). Through engagement of a first transmission shaft (34) with a second transmission shaft (52), the power of an electric motor (32) of the driving device (30) is transmitted to a propeller (53) of the propelling device (50). As a result, when the electric motor (32) drives the first transmission shaft (34) to rotate, the propeller (53) is rotated by the transmission of the second transmission shaft (52) to propel the boat (10).

摘要： A marine propelling system for a boat (3) includes a guide shell (32) having a guideway (33) for guiding a water flow to pass therethrough; a propelling member (40) having a main body (41) and a propeller (42); a vortex guide member (50) mounted to an outlet of the main body (41) and extending backward; a horizontally steering ring (60,70) sleeved onto a peripheral edge of a front section of the vortex guide member (50), a vertically steering ring (70) sleeved onto a peripheral edge of a rear section of the vortex guide member (50); and an inverted guide hood (80) mounted to a rear side of the vortex guide member. When the propeller (42) is rotated, a water flow enters through the guideway (33) and is then pressurized by the propeller to become a vortex flow ejected outward for providing the boat with a propulsive force. In this way, marine propelling system can greatly enhance the steering maneuverability and the safety of the boat.

摘要： A propulsion system for a watercraft includes a concavity (34) formed in a hull of the watercraft. The concavity (34) has a minimum depth at its leading end (36a) and a maximum depth at its trailing end (36b). An impeller (24) is mounted in the trailing end of the concavity and a stator (52) trails the impeller (24). A nozzle (54) having a radius only slightly less than a radius of the impeller is disposed in trailing relation to the stator. An elongate drive shaft (16) extends from an engine (12) mounted fore of the concavity (34) to the impeller (24). An intake grate (40) is disposed in a mouth of the concavity (34). Water flowing through the intake grate (40) flows through the concavity (34) in a laminar flow and encounters no obstacles other than the elongate drive shaft (16) before encountering the impeller (24).

摘要： A propeller (10) includes a propeller shaft (20), a plurality of first blades (30), and a plurality of second blades (40). The first blades (30) are connected to the outer peripheral surface of the propeller shaft (20) so as to be rotated synchronously with the propeller shaft (20). The second blades (40) are connected to the outer peripheral surface of the propeller shaft (20), so that they are rotated in the same direction as the first blades (30). The second blades (40) are located in front of the first blades (30) and correspond to the first blades (30) in a one-to-one manner. The size of the second blades (40) is smaller than the size of the first blades (30), and the rotation direction of the second blades (40) is the same as the rotation direction of the first blades (30). Thereby, the propeller (10) of the present invention can improve the operation efficiency of the boat at high speed without increasing the size of the first blades (30).

摘要： A built-in propulsion system (10) includes an engine (20), a diversion unit (30) with a diversion base (32) and an exhaust pipe (50), and a propulsion unit (72). The diversion base (32) is connected to the engine (20), having a water inlet (34), a water outlet (36), a diversion channel (38) in communication between the water inlet (34) and the water outlet (36), a shaft hole (40) above the water inlet (34) and an exhaust chamber (42) behind the shaft hole (40). The exhaust pipe (50) is fixed on the outer periphery surface of the diversion base (32) in communication with the exhaust chamber (42). The propulsion unit (72) includes a transmission shaft (74) inserted through the shaft hole (40) and connected to the engine (20), and an impeller (76) located in the diversion channel (38) and connected to the transmission shaft (74). In this way, the built-in propulsion system (10) of the present invention uses the exhaust pipe (50) to exhaust the exhaust gas of the engine (20) to the outside of the diversion base (32), so as to avoid the interference of the exhaust gas and the water flow flowing through the diversion channel (38), thereby improving the propulsion efficiency.

摘要： A propeller (20) for a boat includes a hub (30) having a tail portion (36) with an outlet (34), and a plurality of blades (40) equiangularly disposed on the hub (30). The outer periphery of the tail portion (36) defines with a center axis (A) of the hub (30) a distance gradually decreasing toward the outlet (34). Thus, the propeller has the advantages of reducing the drag and increasing the propulsive force of the boat when it rotates.

摘要： A boat propeller (10) includes a gear box (20), an impeller (30), a stream-guiding ring (50), and a stream-shaping nozzle (60). The gear box (20) has a casing (21) and a transmission shaft (27) partially received in the casing (21). The impeller (30) has an impeller shaft (31) and vanes (38). The impeller shaft (31) has a hollow columnar outer shaft housing (32) and a hollow columnar inner shaft housing (33). The inner and outer shaft housings (32) are connected using a plurality of rib portions (37). The inner shaft housing (33) is further connected to the transmission shaft (27) of the gear box (20). The vanes (38) are integrated formed on an outer peripheral surface of the outer shaft. The stream-guiding ring (50) is assembled to the casing (21) of the gear box (20) to house the impeller (30). The stream-shaping nozzle (60) is connected to a rear end of the stream-guiding ring (50) for providing stream-shaping effects. Thereby, the boat propeller (10) has its water inlet diameter maximized, which helps to improve propulsive efficiency.
