How come you can buy a complete 73kwh car for less than one of those 63kwh batteries? So that's the entire car for €40k. Someone's taking the piss somewhat.

interesting how the gear train and prop stands out so much without the engine noise. I would love to see this setup with a Sharrow propeller.

No one burned alive. Good video. Love how quiet it is and doesn't cost more than my home.

I'm just here to read the comments from the haters.

Saving the planet…two batteries at a time.

Interesting that they used Mercury Marine's Verado L6 cowlings, midsection and gearbox.

Ok for a lake boat but where I am (Australia) that range is not adequate.

Happy New Year and thanks for a good one. :)

Finally! I have been wondering how long this would take to get to the market

[rainerhummel]

Seems I have to update my wishlist. Great Boat.

Funny that on the data badge inside the boat, they got the units wrong, showing kw twice instead of kW. And now that more electric boats are being released, please can journalists make a clear definition between motors and engines? I've heard certain journalists go into a twin-diesel engine room to "look at the motors", and here the outboard motor is described as an engine! It's going to get crazy when people start reviewing hybrids.

300 hp is 224KW (746watts/hp). Even with 1000 volt batteries, that's still 224 amps which takes monster thick/heavy wire to run more than 2 meters. Without proper cable thickness, the cables get hot, instead of that current getting used by the motor. If you switch the volts and amps you get 224 volts at 1000 amps. 1000 amps is a peak load for a small subdivision just for this one boat to go WOT for a little while. The copper costs will be crazy. Do you want 400 volt or higher batteries or do you want to run multiple strands of 1awg wire for each terminal on that motor that's drawing 300a? 500a? 1000a?

LPG or hydrogen would be greener, much lighter/faster, far more serviceable vs disposable and I'd even argue safer, although a lithium fire is definitely easy for responders to spot. Why not focus on developing hybrid outboards? The starter motor can be incorporated into the 500 watt or 1KW generator/hybrid motor. It's easy to troll on electric, or leave the harbor or slow cruise quietly, then propane or hydrogen (same engine tech as gasoline) to cover a big expanse of water quickly (while recharging the little batteries if needed).

Only a 30 mile range?? So a trip to Bimini from Miami is out.

[phillbrewer]

If they were to use one of the new Sharrow props, most of the noise would be gone, as the noise would be the prop cavitating

[darthkek]

The range figures show just how subpar electric is at the moment. The problem isn't the engines, or even the cost of the batteries: the energy density for both weight and size, the problem. It does 1/10th the range of diesel and that's with a second power source installed. If you just replaced the fuel tank with batteries, you have something that is about 5% as efficient as diesel. Until the scientists get around that no boat-builder can get around that.

Very impressive and happy new year to all at mby. 👍❤️🇬🇧

[florianhoflehner]

Nice video as always. But unfortunately Too heavy and too expensive

[martinwinlow]

Overall weight of Axopar 25 petrol Vs electric: 1750kg (dry exc engine) + ~250kg (ICE outboard) + 170kg (full 230l tank) = *2170kg* Vs 1750kg (dry exc motor) + ~300kg (e-outboard) + 380kg x 2 (batteries) = *2810kg*.

[areyouarobotz]

It's electric motor, not engine, but in general great video, thank you! Have you reviewed the candela boat? That seems to be the Tesla of boats right now

[bmwietisvoitureelectriqu]

Bonjour combien d'autonomie et vitesse max ?
