ever heard of Electric propulsion system for a 30, boat?

[Truegrain]

I am geting ready to re-power my 30, fishing boat
and would like to trade up my gas guzzlers for
twin electric motors ran by a generator in theory.

I know it has been done on sail boats, however I need enough power to get my 30' SeaRay with a fly bridge on plane.

Am I asking for to much?
Im also open to other propulsion systems that maybe more economical than gas.

Thanks,
Patrick
