a beautiful boat should sail forever.
Thanks to Clyde for a post that really got my wheels to spin.... on a search for prop shaft generator I think I hit pay dirt on
" cruisers forum" see this link http://www.cruisersforum.com/forums/f14/generator-on-prop-shaft-674...
Also some photo of a set up by another cruiser.
It seems there is concern about getting the needed rpms for a generator to produce any power, about 1000 rpm needed . So the pulley on the shaft needs to be large diameter to do this.
But then another post took me to low rpm geberators. Think I found one that will work for me. Waitimg for a reply from them. See this link, http://www.windbluepower.com/category_s/1.htm
$299 seems a good value, Then I will need a pulley for the shaft. Thinking Id like to find something of aluminum I can modify and then split to install as not to remove my prop shaft connections.
see pic of the geerator attached, and a pic of pink clouds fresh painted cummins 107
