摘要:
The invention concerns a housing (1) for an angle gear box device of a boat propulsion motor designed to be immersed and to contain an angle gear box device comprising: two shafts rotating relatively to two perpendicular axes (XX′, YY′) whereof the first shaft (Y, Y′) is driven in rotation by said motor and a second shaft (XX′) drives at least a propeller in rotation; and mechanical elements comprising gears and roller bearings enabling the transmission of rotation of said first shaft to said second shaft. The invention is characterised in that it comprises two assembled matching half-shells (2) produced from a reinforced synthetic thermoplastic polymer material co-operating with each other along a joint plane defined by said axes (XX′ and YY′) of rotation of said rotary shafts and having each; a receased zone housing said angle gear box device in said joint plane, and a planar support surface (4a, 4b, 4c) external to said recessed zone and acting as support on the matching half-shell.

A nonresonant boat motor for imparting motion to a boat without generating a substantial level of sound. The nonresonant boat motor includes a spiral spring coupled to an axle assembly, a propeller shaft coupled to the axle assembly, a ratchet assembly for providing tension in the spring, and an axle rotation control assembly.
摘要:
A new and improved protective cover for the lower portion of an outboard motor including the skeg, rudder and propeller shaft housing to increase the strength of the motor parts covered and protect such parts against water damage and wear. A reinforcing rib may be added for additional strength and an insert plate may be inserted in the cover to replace a missing skeg.

A marine propulsion device is provided with a water inlet system that comprises at least a plurality of frontal inlet openings at the tapered forward end of a gearcase portion of a housing structure. The water inlet system can be provided for an outboard motor or a stern drive unit. Additional water flow can be provided through side inlet formed in the housing structure of the marine propulsion device where both the frontal inlet openings and side inlet openings are connected with fluid communication with the water pump mounted within the housing structure.

A marine outboard engine includes an engine having a front, back, top and two lateral sides. A cowling, covering the engine at least partially, includes a central support structure fixedly connected to at least one of the engine, a swivel bracket, and an exhaust system. The central support structure extending across at least a portion of the front, top and back of the engine defines at least partially a space through which at least a portion of at least one of its lateral sides is accessible. The space is selectively covered by at least one side panel which is at least partially selectively connected to the central support structure and at least partially disconnectable therefrom to reveal the portion of the at least one of the lateral sides of the engine while the central support structure extends across at least the portion of the front, top and back thereof.
摘要:
A marine propulsion mechanism submersible in water for driving a water craft is disclosed. The propulsion mechanism includes a streamlined housing having a fluid inlet opening positioned between the forward and rearward ends of the housing in addition to a fluid discharge opening at the rearward end. A tubular support is joined to the housing for mounting such upon a water craft. An inlet scoop extends outwardly from the housing and directs water to the fluid inlet opening. The scoop is provided with a rigid tube having a first end secured about the fluid inlet opening and a second end terminating at forwardly directed duct remote from the exterior surface of the housing. The scoop further includes a screen set within the forwardly directed duct for preventing debris from entering the housing interior. An impeller is rotationally secured within the housing adjacent the fluid inlet opening. Rotation of the impeller draws water through the inlet opening and discharges it through the outlet with jet-like force. In the principal embodiment of the invention, a geared transmission is secured within the housing for transmitting the energy of an above-board electric motor to a pair of impellers. In a second embodiment of the invention, an electric motor unit is positioned within the housing for rotating a single impeller.
