Yes but 400l tank on 7.5m rib is not very light, thats 300kg.

Not only the battery size and weight, but the cost. This 180 HP electric outboard will cost around $120,000 when factoring in motor, batteries, controls and all rigging parts. New 200 HP Mercury is around $20,000, call it $25,000 with rigging. If this boat owner only goes 30 miles per outing it would take decades to make up that extra $100K in fuel savings. Big electric outboards (over 15 HP) are a nice idea, but not there yet.

Until we put a price on carbon emissions this will continue to be the case for a lot of things. And yeah it kinda sucks, engines are cool and have allowed us to do a bunch of stuff but I'm willing to embrace this new concepts if I have the money and eventually price will drop and it will make sense for more people

and are you taking the boat out on your EV truck?

Yes, On a day of playing at the lake with family we usually put 20 miles on the boat. Lots of throttling up, running full throttle and pulling tubes which requires more power. Then a day of fishing, even inshore or freshwater we may travel 10-20 miles. It is a very cool concept for those who prefer leisure time on boat, but for not for someone who uses a boat for distance, speed or loads. Definitely not for a fisherman

You've essentially described a perpetual motion machine which, according to the 1st and 2nd laws of thermodynamics, cannot exist or at least cannot exist "efficiently" or allow any net gain in energy. Unloaded, a generator or alternator, is easy to spin by hand. However, put it under load (such as charging a battery or powering an electronic device), and it can become very difficult to turn. If you've ever switched on a high-power car audio amplifier or headlights (in an older car that uses the old inefficient round incandescent headlights), you can hear the RPM's of the engine drop as the alternator suddenly sees a significant electrical load (I use an older car for this example because the computer in a modern Fuel Injected car would quickly sense the load and automatically increase the RPM's). If you connected a generator, or an alternator, as you suggested and loaded it enough to get some useful energy out of it, it would place a significant drag on the boat or the boats motor. This in turn would require more power from the boat's motor to compensate. You can't get something for nothing. You'd end up using a lot more energy to power the boat. The differential would actually be greater than the small amount your generator would produce.

I understand but design a hub to be able to harness the movement Without being a load, it would be four mini-stators with no parasitic loss, because of 4 hubs available. Wouldn't that work?

No it would not work, as above you have described perpetual motion. Bigger hub would make it worse too. We are a battery breakthrough away from this “really” working

They are working with McLaren to develop another kind of gears, we will see...

100 hours? Outboard engines need service every 100h, how long do you stay off shore without coming back to marina 4 days?

I know two people with sharrow props, neither enjoy that kind of efficiency gain. Much much lower gains than 25%

I bet sailors said the same thing about the magnesium in gas outboards... which caused plenty of fires.

OMG what a major fail. Considering the number of boat fires that occur every year from gasoline engines your comment show's you're rather benighted. To avoid looking like a complete moron when attempting to traduce EV's and Li-ion batteries, you might want to spend a little time performing at least a modicum of RESEARCH.

I noticed that too. When the water started blowing up around the motor it was very obvious. I'm sure they could get better range and speed if they installed it correctly. Maybe they need to study up on that, or the use of a jack plate. LOL

I don't sell this engine. You need to contact Vision Marine

400 Lbs

@@yachtandseatv7160 Not including batteries.

Of course @@96thundercat

400lbs for a 180 is pretty good. Just need to get much better range to make it usable.

Please, send me more information

Around 120 K the complete system with batteries and controls. But It's not available like that, only on OEM, you can't buy it separately for the moment.

You don't need the 220, a regular plug is enough

In the electric outboard world, it was...not alone anymore, but it was. It's exactly for this reason that Beneteau Group signed a deal with this brand

For fuel cell applications perhaps.

The hydrogen technology is coming but not totally ready for boats and mostly for small boats. Sunreef will produce one in 2024.

You are right, that's why the brand is working with McLaren to change that.

@@yachtandseatv7160 I made an electric outboard, and when I had this problem I went to a direct coupling. No gears, no gear whine.

This is a statistic, nothing more. you're one of those people who does a lot of sailing, bravo!

Right, but... there will come a day when the electric hp is cheaper than the gas hp. Last year the battery KWH halved in price and will reduce by 40% this year. Once tech is learned, it's there for ever. The future is electric.

@@jamesdonaghy9143 umm no. one again its a matter of range and weight. both things batteries will never be nearly as good at on a weight sensitive high load scenario. can get away with this in a car, but not a boat or an aircraft. the negatives are just too insurmountable for the forseeable future. im not sure what you mean by price being down 40%... your saying the price of electric outboards are down 40%? impossible. and again, where are you charging on the water for the vast majority that doesnt have a private dock/shore power?

@ct1762 The price reductions I mentioned concern battery units, which will eventually translate into outboard prices. The wind and solar sources are also improving in watts per dollar and watts per Kilo, with no clear limits established, going forward. Cases where fossil fuels are the smart choice will diminish going forward until they become obsolete, a happy prospect for all biological entities.
