Being green won't be the driving force toward electric boats, either. Lower operating costs will. Consider the 32-foot Wenona built by Elco in 1899 and recently refurbished by Hall's Boat Corp. in Lake George, New York. The boat is still running on her original electric motor and controller after 115 years of not particularly gentle use. "Somewhere around 1,000 to 3,000 hours, a DC motor needs to have the brushes replaced and commutator dressed," Fleming says, but little else. Both were completed, and Wenona's electric motor was rewound with new copper wire. The original electric controller — a rotating wooden, brass and copper 10-pole switch that alters connections between two battery banks and two resistors to vary her speed — also needed surprisingly little work.
