OK the bottom line is Iwas thinking a 400-500 hp turbine turning an efficient brushless generator would be an easier way to have a single engine twinn drive full size powerboat.I quess it would be feasable to scale up a brushless motor and have at it but with money and time invested it might be cheaper to go tripple turbine.It's only a 32ft.cat anyway,just thught it would be cool to be the first high-perf.full scale elec. guy.Thanks for your time fellas.
