Serviced tow generator

A combination wind/tow generator came with the boat.  It was unmarked and I had some difficulty in finding out what it was.  It is a “Redwing” generator made by Downwind Marine in San Diego circa 2001.  A guy named Chris at Downwind Marine was enormously helpful in providing detailed answers to my most detailed questions–I believe he may have been the one who designed and built them.  (They aren’t building them anymore, he said, because the guy who made the blades stopped, and the increasing difficulty of permanent magnet DC generators). The generator is super heavy, and super overbuilt, to my immense enjoyment.  I dismantled it in order to check the brushes and potentially rewire it (the cord was looking manky).  I called Chris in order to figure out a detail of dismantling it: the cylindrical fitting was corroded to the shaft and I needed to know whether the fitting was threaded onto the shaft.  Chris told me that it is not threaded onto the shaft and moreover that a 1/2″ bolt can be threaded into the end of the fitting in order to conveniently press it off the shaft.  Even with this aid, I still needed to put a long extension pipe on the socket wrench in order to get the torque to remove it.  This removed, I could access the interior of the generator to check the brushes (fine for now) and to clean the commutator, etc. The only thing that remains is finding the other parts that are necessary to rig it up as a tow generator–I know they’re on the boat somewhere but I sure as hell don’t know where.
