     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 to 6 thereof, a new and improved solar powered trolling motor embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     FIG. 1 illustrates a prior art solar cell conversion unit 1, wherein a solar cell panel 3 mounted to a housing 4 includes bracketry 2 to mount the organization to an associated bicycle, as set forth in U.S. Pat. No. 4,871,042, utilizing batteries in operative association with the solar cells for directing current to an associated drive motor whose organization is incorporated herein by reference. 
     More specifically, the solar powered trolling motor 10 of the instant invention essentially comprises a housing 11, with a top surface defined by a housing rear top wall 14 arranged relative to a housing forward top wall 15 defining an acute angle therebetween. The rear wall 14 includes a first solar cell panel mounted thereon, with the forward top wall 15 including a second solar cell panel 13 fixedly mounted thereon to optimize orientation of a solar panel relative to solar reception. DC solar cell batteries 16 contained within the housing 11 are in operative association with the solar cell panels 12 in a manner as set forth in U.S. Pat. No. 4,871,042 incorporated herein by reference. Optionally, an electrical plug receptor 17 is securable with an electrical plug 18 that is in electrical communication with an electrical transmission line 19. The electrical transmission line 19 includes a first electrical connector clip 19a and a second electrical connector clip 19b for selective securement to a remote battery available to an individual due to failure of the solar cell panels or in the situation of limited solar energy available. A steering and rheostat rod 20 is provided to provide variable speed of the associated DC electrical drive motor 24 contained within a casing that is orthogonally mounted to a drive shaft column 21 mounted to the housing 11 by a collar 22. A clamp assembly 23 is typically rotatably mounted relative to the column 21 to permit relative rotation of the column 21 and steerage of the organization by orientation of the output shaft propeller 25 relative to the drive motor 24 and its associated housing. 
     FIG. 4 illustrates the use of a modified trolling motor organization 10a of support tube 29 that, at its lower terminal end, includes an externally threaded collar 27 receivable within an internally threaded bore 26 through the top wall of the trolling motor housing 11. A thumb wheel 28 fixedly mounted overlying the externally threaded collar 27 permits relative rotation of the collar 27 relative to the bore 26 for its association. A solar panel 30 is mounted to an upper terminal end of the support tube 29 by a pivot connection junction 31 to permit manual pivotment of the solar panel 30 relative to the support tube 29. A solar panel connector plug 32 mounted to the lower terminal end of the support tube 29 provides electrical association between the solar panel 30 when the support tube 29 is directed within the bore 26. FIG. 6 illustrates the use of a modified solar panel arrangement that further includes a pulley member 34 that is rotatably mounted adjacent to and spaced above the thumb wheel 28 and associated collar 27. An elastomeric tension cord 33 is secured at a cord forward terminal end 33a to a forward terminal end of the panel 30 and utilizes a cord rear terminal end 33b mounted adjacent the panel 30 rear terminal end such that pivotment of the panel 30 about the junction 31 maintains the panel 30 in a desired angular orientation due to the frictional tensioning of the elastomeric tension cord 33 relative to the pulley member 34. 
     As to the manner of usage and operation of the instant invention, the same should be apparent from the above disclosure, and accordingly no further discussion relative to the manner of usage and operation of the instant invention shall be provided. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
     Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
