Abstract
A belt driven outboard drive and engine assembly mountable to the transom of small flat bottom boats in much the same manner as water-cooled outboard engines. The assembly includes a lower drive shaft assembly that does not extend below the bottom of the boat, but extends a sufficient distance behind the boat to insure the proper angle of attack when the propeller is positioned for contact with mud and vegetation. The engine-mounting bracket includes a unique dual pivot tilt-up and tilt-down capability, an incremental positioner and a pivotal horizontal steering handle. The propeller is capable of cutting through vegetation, provides propulsive thrust in mud and provides relatively fast boat speed in deep water. The assembly further includes a clutch and reverse drive electric motor.
Claims35
An outboard belt drive assembly having an extended drive shaft assembly comprising:
- a) a frame assembly for mounting a utility engine;
- b) a mounting bracket assembly attached to the frame assembly for temporarily attaching said outboard belt drive assembly to a boat transom said mounting bracket assembly having a pivotal assembly for positioning said belt drive assembly in the horizontal plane;
- and
- c) a first and second pivoting assembly for positively and negatively positioning said belt drive assembly beyond vertical respectively relative to the mounting bracket assembly-in the vertical plane.
An outboard belt drive assembly comprising:
- a) a drive housing having an upper end and a lower end;
- b) a drive shaft assembly attached to said drive-housing extending outwardly from said drive housing at said lower end;
- c) a frame assembly attached to said drive housing located adjacent said upper end extending perpendicularly from said drive housing opposite said drive shaft assembly;
- d) a removable transom-mounting bracket having a pintle assembly pivotally attached thereto said pintle assembly having an upper and a lower end;
- e) a pivotal locking assembly for attaching said upper end of said pintle assembly to said frame assembly;
- and
- f) a block assembly for pivotally attaching said lower end of said pintle assembly to said drive housing opposite said drive shaft assembly.
An outboard belt drive assembly comprising:
- a) a drive housing having an upper end and a lower end;
- b) a drive shaft assembly attached to said drive housing extending perpendicularly from said lower end;
- c) a frame assembly attached to said drive housing located adjacent said upper end extending perpendicularly from said drive housing opposite said drive shaft assembly;
- d) a transom-mounting bracket having a pintle assembly pivotally attached thereto said pintle assembly having an upper and a lower end;
- e) a first connection block rotatably attached to said upper end of said pintle pivotally connected to said frame assembly;
- f) an actuator assembly attached to said first connection block;
- and
- g) a second connection block rotatably attached to said lower end of said pintle pivotally attached to said drive housing opposite said drive shaft assembly.
A method for positioning a transom mounted outboard belt drive assembly relative to said transom comprising the steps of:
- a) attaching a belt driven outboard drive assembly temporarily to the transom of a marine craft comprising;
- I) a drive housing having an upper end and a lower end;
- II) a drive shaft assembly attached to said drive-housing extending perpendicularly from said lower end;
- III) a frame assembly attached to said drive housing located adjacent said upper end extending perpendicularly from said drive housing opposite said drive shaft assembly;
- IV) a transom-mounting bracket having a pintle assembly pivotally attached thereto said pintle assembly having an upper and a lower end;
- V) a pivotal locking assembly for attaching said upper end of said pintle assembly to said frame assembly;
- and
- VI) a pivotal block for attaching said lower end of said pintle assembly to said drive housing opposite said drive shaft assembly;
- and
- b) engaging and disengaging a positioning assembly thereby setting a desired pivotal angle for said drive assembly relative to said pintle.
A method for reversing direction of a transom mounted-outboard belt drive assembly comprising the steps of:
- a) configuring a transom mounted belt driven outboard drive assembly to comprise;
- I) a drive housing having an upper end and a lower end;
- II) a drive shaft assembly attached to said drive-housing extending perpendicularly from said lower end;
- III) a frame assembly attached to said drive housing located adjacent said upper end extending perpendicularly from said drive housing opposite said drive shaft assembly;
- IV) a transom-mounting bracket having a pintle assembly pivotally attached thereto said pintle assembly having an upper and a lower end;
- V) a pivotal locking assembly for attaching said upper end of said pintle assembly to said frame assembly;
- VI) a pivotal block for attaching said lower end of said pintle assembly to said drive housing opposite said drive shaft assembly
- VII) a utility engine attached to said frame assembly;
- VIII) a clutch attached to said engine and connected to a belt drive gear located within said drive housing;
- and
- b) attaching an electric motor having a second drive gear in mesh contact with said belt drive gear.
