Would the attributes of an electric 150 hp motor be a plus or a minus compared to a gas engine when used in a boat?

Compare This. You Will Need A 3 phase Generator. A Soft Start 150 HP Starter This Is The Control That Starts The Motor. It Will Cost Well Over $1500, The Generator Will Cost Big Bucks, The Motor Isnt Cheep, Around $1400. Plus The Wiring. Then Some Type Of Gearing Or Transmission Of Power From Motor To Propellers. Also Check Out The Weight Of All This. A Good Sub Might Be OK ! But A Boat NO WAY !

AnswerA 150 HP motor would use 111,900 Watts Full load. A motor this size would weigh roughly 3,000 Pounds and would need a generator as big as a Mack truck (15,000 pounds) to power it. Or an extension cord that is as big around as your arm from the power company to your boat. Or you could use 31 car batteries that would run it for a couple minutes. Now if your talking about a ship. Diesel electric and Steam electric engines went out years ago as they are not economical. However they made going from forward to reverse easy.
