    Many will use the e-prop more than 50% of the time, it saves fuel, engine hours, is more enjoyable, more reliable. 255 amp hrs is a good benchmark ... From:

      The facts are the link appears to be for intermittent electric propulsion use on sail craft - ie. for short hops: "Perfect for lake sailors; plenty of power and range to get out to sail Enough range for weekend sailors to motor home, if the wind dies" - and shore power recommended. Note that Electric Yacht advise "For extended trips (sailing) away from home, a small gasoline generator can be used to charge the batteries through these chargers." http://www.electricyacht.com/faqs/battery-selection/ Why then add the $4000 for the hybrid drive to the ICE dollars on a power cruising craft? How many batteries by your calculations?
