I'm starting to understand why most manufacturers have put the motors under water where the gearbox would be, not only the added efficiency of eliminating gears might offset some of the additional drag but the noise difference is incredible. This motor is arguably loud and part of that might just gears but also the vibrations of the prop passing through the keel turbulence transmitting through the shaft.
The motor is not a problem. The battery capacity and size are issues. More battery more range and of course more weight on the boat and less storage space.
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
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
I say the way to go is to build direct ammonia fuel cells to power electric boats. These will solve the range and weight issues. Batteries in boats are not the best mix.
30 miles 💀 did more than that on my skiff during a day of fishing. My current boat has 300 miles of range on a tank. I’ll go up to 75 miles one way offshore in my current boat.
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
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.
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.
Be ok as a Saturday afternoon family ski boat .....but to get offshore need 100hrs of battery life bare minimum to take it seriously as opposition against petrol n deisel
That outboard in installed too low on the transom by the way. Another fail! That thing is giving me a headache just through YT, I cannot imagine in person. Terrible!
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
30 miles is not good range at all, normal range for boat is 200-250 miles, if I get this boat I should stop in middle of my day to do full recharge so I can get back home
The horrible, whining noise coming from the gearbox is a no go. The range more importantly, is also a no go. Don’t forget the cost of a electrician to wire the 220 to your dock.🤦♂️
Omg, that motor will never sit on my boat with that high pitch sound, not only is it loud it is a terrible sound, if it was completely quiet like an electric car (without artificially generated sound) it would be compelling. But to change a gas engines nice growling sound to that? Nope. One positive though, it looks good.
30 nMi is double what the "average" boater uses? are you kidding me? My offshore tuna trips alone are over 130nmi. all on my 2007 225 Evinrude. hasnt skipped a beat in 16 years, and got it for $3k. 40 miles is just a joke. and thats just at cruise. long long way to go on the water if you want to beat gasoline or diesel my friends.
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.
