something new coming in electric OB

As i was posting this i was remembering putting playing cards on my forks.


lets see who gets that....

We used baseball cards.

It makes for a simpler drive train.----No different than azimuthing drives on big ships.----Or the electric motors driving the wheels on those monster mining trucks.----Read an article on mining trucks that do not use any fuel or battery charging from the grid.----They generate power loaded on the way down the mountain.----More power than is needed to run the empty truck back up the mountain.

Unfortunately no downhill charging on a boat motor.

I know that, but if the power from diesels is better as stated why introduce electic. Maybe at beginning for the tourque but once going?

Well you also left out dynamic braking. The electric motors help to stop the damn thing as well.

unless you are rich and have your own powersource at your own private dock, where are you going to charge these things? big marinas will not let you tie up their shore power for anything less than a fortune, and on any given summer day they are booked months sometimes years in advance. also, a massive drawback for batteries that few mention is that they dont get lighter as you go. charged or full, you are still carrying around dead weight. weight sensitive craft like boats/aircraft suffer the most. and no, there is not going to be some magic tech that comes out and makes batteries 2x as power dense. physics/thermodynamics has its limits. Just because Elon Musk says its true doesnt make it so.

Well, I hate to say it but they all thought the world was flat until one guy ....

In 1491 nobody with a brain thought the world was flat.

in case the batteries give out... MXR2300 or 3500

The short answer is steel on steel traction with huge weight to HP ratios.

Much easier to control traction (torque) and speed electronically than with a gear box

Reciprocating motors generate torque by rpm. To maintain a content torque, yet variable speed output, would require a sophisticated gear box of some shorts with its inherent loss of efficiency.

On the other hand, the speed and torque of an electric motor can be controlled electrically with great precision with little, if any loss of efficiency

of course the issue is still heavy , inefficient batteries. dead in the water.

Sorry that I'm adding to this never ending end, to this thread.

Watch this and I had a little trouble watching it because of the platform but Yamaha's new hydrogen powered outboard.

Why then do diesel locomotives convert to electric? Honest question.

An Electric Motor can have Torque at 0 rpm, something an ICE can't

Yamaha's world-first hydrogen outboard unveiled on prototype boat

Yamaha previously announced it would show its prototype hydrogen-combustion outboard motor at the 2024 Miami International Boat Show, and it's gone the extra mile in bringing a prototype boat and fuel delivery system to go along with it. Yamaha calls its new hydrogen V8 outboard a world first for…

your looking at it wrong. The electric motor isn't the problem. As a matter of fact, the electric motor might even have a greater power to weight ratio over an internal combustion engine.
Regardless, the problem with an EV is the "gas" tank, the battery.
Actually, the diesel engine/kerosene combination IS the gas tank that supplies the power for the electric drive.
There isn't a battery big enough to drive that locomotive.

Japan's oldest outboard builder silences seas with all-electric motor

Yamaha may be the largest, most well-known manufacturer of outboard motors in Japan, but Tohatsu Corporation beat it to market by a couple years back in the mid-20th century to become the country's first outboard producer. Tohatsu remains a venerable force in outboard production today and is now…

Developed for the Gemera four-seater, this electric motor, dubbed the Quark, is a tiny powerhouse. In a package that weighs just 63 pounds, the Quark develops 335 hp and 443 lb-ft of torque. For scale, that's a 330-mL energy drink in the pictures seen throughout.

Much better platform for reading the details. Thanks

Gee, some still think today that the earth is flat. It's a movement!

I stand uncorrected!...wow.
