Seven Marine no more :(

What are they going to do in California, they have rolling black outs now, they can't provide enough electricity to power homes. How are you going to have enough electricity to charge your car, boat and keep the lights on in your house or business?

"In the future, the world will be powered by a combination of battery-electric and fuel-cell electric vehicles ... "
Good luck with that theory. We are slowly transitioning to more practical and fun to drive electric cars but are a long ways from practical, let alone fast, electric boats. Will we have electric jets too? Large cargo ships could go nuclear like warships and submarines have. Anyway it is sad to see Seven Marine go the way of the Ilmor V-10.

I completely agree with your statement. Horsepower from electric motors is not the problem currently, it is only the energy density of the batteries - which is currently only about 1/10th that of gasoline. Once the battery technology advances and the energy density approaches that of gasoline, we will see electric everything - cars, boats and even airplanes. I do hope that everybody goes online and educates themselves to the fact that our ships and trains have been powered by electric motors for decades now, with either diesel motors (trains, commercial ships) or nuclear reactors (military ships, submarines) providing the source of energy to create the electricity to power the electric motors. The first flight of a commercial aircraft has already occurred last year when a converted De Havilland Beaver seaplane with a 750hp electric motor/battery system developed by MagniX flew a short route up in Vancouver, Canada. All electric is coming guys, it's just a matter of time.
I think we'll see more vehicles powered by electricity in the future, but NEVER to boats like ours...ain't happening, at least in our lifetimes, not without some unforeseen technology 'breakthrough', anyways...and still, at least 25+ years off. For the foreseeable future, nothing beats fossil fuels.

Not to split hairs but...no, nuclear powered ships don't use electric motors to drive the ship...they use the reactor to generate steam to power steam turbines...that drive the ship through a gearbox, not via electric motors.

Eventually diesel may be the remaining fuel source for internal combustion engines as land based transportation migrates to electric. Diesel would still be in use for some big stationary applications.

You may want to do some research before posting..........

....another thought.
Its been hard enough for me to mentally adjust to the sound from a 100mph boat that had 1075's to a 100+ mph cat that has much quieter outboards. Now ya'll want to make them totally silent. SMH
