[Electric Boats] almost finished boat [1 Attachment]

I have for the past 4 years been building a 23 foot fantail launch.  The original plan was to power it with a steam engine and for that reason I modified the design to accommodate an 18 inch prop.  The more I learned about steam power the less enchanting it became and I am now far more inclined to use electric power but I know I have a lot to learn first.  Most of what I have done so far has been to look at web sites and make phone calls.  I was surprised to see the huge price difference between Elco and Thunderstruck and would wonder if anyone has some insight on that.  I have also seen a posting on the wooden boat forum about using a golf cart motor.  What other sources are out there?  My gut feeling is that the boat should be pushed with a low speed large prop but I do not know if that will require a reduction gear and I would like to learn more about what people use for props with electric power. Can electric deliver the torque for a large prop?  The other question I wonder about is the utility of solar panels.  The boat will have a roof that covers the entire 14 by 6 foot cockpit so there would be a lot of room for panels.  Do they charge well enough to extend cruising range to a full day?
