     With reference now to the drawings, and in particular to FIGS. 1 to 6 thereof, a new and improved outboard motor retrofit generator apparatus embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     More specifically, the outboard motor retrofit generator apparatus 10 of the instant invention essentially comprises a rigid generator housing 11 coaxially oriented symmetrically about a housing axis 12 that is mounted to an outboard motor, and more specifically to the outboard motor drive housing 14, with the outboard motor support housing 13 directed from the drive housing and mounted to a boat in a conventional manner. The generator includes a plurality of generator housing tubular ribs 16 directed in an annular array about the exterior surface of the generator housing 11. Each of the tubular ribs 16 receiving a fastener 17 directed therethrough, with the fastener received within a drive housing receiving bore, in a manner as indicated in FIG. 2. The outboard motor includes an outboard motor output shaft 18 (see FIG. 3), with the outboard motor output shaft 18 having an output shaft threaded distal end 19. An extension shaft 20 is provided, with the outboard motor output shaft threaded distal end 19 received within the extension shaft first end 21 configured as an internally threaded socket. The extension shaft second end is externally threaded to receive the propeller &#34;P&#34;, as illustrated in FIG. 1. The generator housing 11 includes a housing first end plate 23 spaced from a second end plate 24. An armature 25 relative to a stator 26 are coaxially oriented within the generator housing 11, whereupon rotation of the extension shaft 20 mounting the armature 25 thereto, electricity is directed from the generator structure through output lines 27 mounted within a flexible shield conduit 28, having its first end directed into in sealed communication with the generator housing 11 and the second end of the shield conduit 28 directed along the outboard motor support housing 13, wherein the output lines 27 are directed to the battery &#34;B&#34; through a voltage regulating device 32. 
     As illustrated in FIG. 5 for example, the output motor output shaft 18 is received through the generator housing first end plate 23, and more specifically rotatably mounted within a first bearing 29 sealingly engaged by a first seal 33. A second bearing 30 coaxially aligned with the first bearing 29 is directed through the second end plate 24 rotatably receiving the extension shaft 20, with a second seal 34 oriented between an exterior surface of the second end plate 24 and the second bearing 30 to sealingly in a fluid-type manner secure the contents within the generator housing 11.
