Electric Outboard first in water test
HTML-код
- Опубликовано: 2 дек 2024
- This is the first test of a prototype electric outboard motor built by Inertia Labs under commission (www.inertia-lab... ). The goal was to get performance comparable to that of a 25HP gas outboard. We used twin eTec electric motors, coupled with belt drives,and throttled by an AXE speed controller running both motors. We used two early versions of the ZERO motorcycle LiOn batteries at 48v in parallel.
Beautiful, quiet and fast, friendly environment! No matter how many hp equivalent, the important thing is that it works well. Congrats
Those Manta 2 motors put out 10 horsepower each motor so he's got an equivalent of 20 horsepower there had he used the water cooled motors instead of the motors he's using which they do make a water cooled motor it has coil copper around the housing he could have used the lower units cooling water pump system that's in all outboard motors to pump water out of the lake around the motors and it would have kept them cool he probably would have doubled his time on the battery and remember the more batteries you got the longer time you get and if you can get some solar power panels on the roof of a boat just put four poles on the boat and throw some solar panels up there to recharge your batteries at some point you're going to run out of juice but you can have a fun day out on the lake before you ran out of juice and you don't have to worry about your motors overheating if you've got cool water from the lake pumping around your motors he's got the principal right he just needs to add a cooling system and a recharging system so he can get more time on the lake
Finally. Somebody that reported real measurements. Keep at it guys. Use gel cells as they can handle direct sunlight. Build a permanent housing for them and use anderson connectors that can be handed pierside to an external charger.
awesome.....I love that you guys made a motor that can still haul ass, but doesn't put all the crap into the water. Every lake that i go to that allows gas operated outboards has an oil slick on the top of the water ( just from all the boats running their exhaust into the water )
I've clocked our 14 foot aluminum boat at 30mph (50km/h - GPS actually). That has a 25 horsepower motor. The difference between 22mph and 30mph is huge. You probably have more like 18hp, maybe a little more.
how about adding a top cooling air intake snorkel and discharge to aid in motor cooling?
This is awesome!! They need to push these into mass production.
I agree that performance is on par with a 25hp motor on that boat. Very cool!
That's great guys! Looks like it moves right along. The earth appreciates it.
SERIOUSLY cool project guys, brilliant stuff
It needs air flow
yep !!
You are aware that the Manta 11motors , they have one that has water jackets on it. basically it's coiled copper around the motor . and you've already got a water pump in the lower unit of your old motor ... so you can pump water around your motors to keep them cool right out of the lake....
i wonder how long the motor will last not being vented . seems like you did what 4 trolling motors can do better but hell i dk what to think but its kinda cool
that was sick bro... you should just put a vent chimney on the motor case make it 8 inches or so high so the heat can escape and you could put a fan in the chimney as well. use pvc for the chimney...
condensation is forming inside the case. You should have built splits to circulate air inside the Motor COVER
A solar vent on top of the box might exhaust the warm fog and cool the motors. I had a vent for my enclosed battery/controller.
I must say that's rather impressive.
2.29 , it is like a plane is approaching, nice vid and nice motor.
So how did you do this to where your three phase wires wouldn't get hot because I did this in my three phase wires smoked up at the motor
WOW, very impressive speed. Great job, looks so neat, too.
are the motors car alternators?
No. But I'd like to know what he used as well. I am going to use a starter/generator motor off of a older lawn tractor. Two batteries don't have enough storage capacity to run this little boat on or nearly on plane for an extended period of time. They would likely last all day at partial throttle. Nice job by the way!
Maybe washer/dryer motors
Bob Ordewald Bob, it looks like they used a couple of the ETEK DC motors or the cheaper copies with an alltrax controller, it's probably a 48 volt system. I think the actual ETEK motor is not made anymore but the copycat versions are still available for around $400. ea. I think there's even a 10 hp version for around $700. Ebay or an electric motorcycle website should have everything you need. Best of luck! Chris B.
Read the description and it will answer all your questions....duh
I'm sure with your superior brain that you never miss anything or make an error. To be gracious appears to be beyond you. Sad little fellow. You are a small mean person. You could be the poster boy for making birth control retroactive!
if the prop stops suddenly, will it strip the teeth on the drive belts, when you star big power tools if the tool is locked down or stuck and you turn on the motor,,,,,it eats the drive belt.
Did one etec get hotter than the other? Did you test both of them to see if one was working harder than the other?
awesome build!
how does the two motors work together to make it work
if you could incorporate a alternator in there with motors and have it tied together so every time you run motor it would charge batterys back up...just a thought
+Vernon Yow A not very sound thought, I'm afraid - you'd use energy from the batteries to recharge the batteries themselves, with losses, that'd just eat up more energy.
Why not put the batteries under the first seat ahead of the motor? Less wire less resistance.
Weight distribution is also a factor.
How did you build this and where can I source the parts and info on build?
How high is the torqe? If it is high enough you could use a larger prop with a greater pitch, ala the prop used by the Torqeedo motor.
I love that you used plexiglass to be able to see what you're doing, and the video shows why temperature is such a key factor for electric boating. The battery choice was a good one - much better than most electric boat efforts. Great to see. Is this video taken in Sausalito?
To see a fast electric boat, see my videos...
Run a flat copper bladder / Pipe beside the fields make one end in the water like a small funneled P/Up motion pipe for cool water let it run by the motors run way cooler . Good idea lotta force .
It needs ventilation and cooling!! Put a vent fan on it, there's no way for the heat to dissipate. but honestly that seems like an awesome idea!
Tyler Scott it would be better to liquid cool it. electric rc boats are liquid cooled pretty easily.
Wow really loud. Why didn’t you use 24 volt DC motors. Great idea.
sealed in a box no ventilation what about salt water?? looks neat good job!!!
I would totally buy this if it were similarly priced to a 25hp
"can't see the temperature of the motor because of the fog built up inside..."
"...taking a look at the motor casing, looks like it's staying dry, no moisture inside"
lol
Say - ‘condensation’... now look it up... haha
how can anyone not like this! You know how much gas gets spilled in our waters? This is bad ass and there's 7 HATERS. This is awesome!
Nice, electric motor outboard... never used gasolines and oil...only batteries fuel... 1k to 100k RPM at 40 to how many kilometers per hour travel before to drain the battery...?
seems super quiet been wanting to get a electric motor for my jon boat this just makes me want to het one more ya'll keep on building boys!
Shorter, heavier cables needed. Performance looks on par with a 10 hp. Very cool project. As with most of these types of things, battery life is the weak link.
Very cool idea, but a 25 HP 2 stroke motor would push that aluminum a lot faster then 22 MPH. I have a 25 HP Johnson on a 15 Foot fiberglass runabout that's pretty heavy for its size. I get around 22-24 MPH out of her never mind the motor on a light aluminum boat. Awesome idea tho I would like to see the final product in a video!
GREAT GREAT GREAT GREAT. I coach rowing. My launch is a catamaran. I do not go any faster than 20KM/hour. The launch I have is a stillwater weighs about 250 pounds. I currently use a 15HP motor that is PLENTY of power. I can't wait until I don't have to drag gas down to the launch anymore. I coach three hour stints every second day or so. What are my current options?
Thank you and great job. Keep innovating let's get rid of foreign oil!
That's pretty cool! How long do you get before the batteries are out? It would be neat to be able to swap my 15 HP 2-stroke for an electric outboard, but if they're anything like electric cars, run time must be a problem? My minivan can go from San Jose to San Diego without refuelling so long as I keep my speed down; no electric car comes anywhere near that range.
great job. how much to build?
that is awesome great engineering guys. y'all nailed it
Nice..
how many watts of a motor
How are the motors getting any cooling? Where is the airflow or are the water cooled? Is that a sealed case? How is the motor controller getting any cooling at all? No wonder you are getting increased temp readings
wow im impressed!!!
as for the engine heating up why dont yall run water from the lower unit up to cool the engine, just like in a gas outboard. Just a thought...cause i know that eletric RC boats use water to cool their engines also.
Nice, good job. I saw one where they took and outboard bottom end, and bolted on one of those big ones like from a car 150Kw motors. it was FAST.
This is interesting, but will only work for short pleasure cruises. Where I live, it takes me 30-40 minutes of driving at 15 knots to get to the open sea, and if I'm going fishing I need another 20-60 minutes of driving to get to a good fishing ground. Then I need to get back home and I want to have at least one to two hours of driving in reserve. Once a battery powered engine can do that, I'd be interested in buying one.
Add a sail.
Good speed, and better performance then some others I've seen on youtube that are manufactured for money basically a 9.9 for top speed.
great built, how much kg does the whole engine have
doesn't beeping mean they are going to explode?
ummm... did the electric motors overheat pretty quick being you have them in a SEALED CASE!?!?
thats pretty awesome, have you improved on the design at all since this video?
where do u get that boat i looked on all the websites ik
thumbs up ~ very cool dc motor project ~ how many watts per motor ~ or total power is consumed @ full throttle? just curious...I think its fantastic ~ also, does it get better mileage just doing hull speed? vs plane?
That looks like an Alltrax golf cart controller. Am I right?
dude and with fluid cooling available now . . . temp won't be a problem . . .you all need to figure out how to get rid of the batteries . . . . I can help with that
Dam very impressed .. I like your set up !!
Great build by the way... Just a couple questions. Did you experiment with different size and pitch props? Second would be . Would shorter battery leads draw less resistance and thus get more out of your batteries. I know the weight distribution would be changed but the driver could sit forward a bit with a longer handle? Just a thought. Hey good luck on your cool build.
Exactly. Long cables are fine, just need to be larger diameter to feed that many volts/amps.
And the pitch of the prop, should been a no brainer, almost unlimited tourqe. Should = large diameter and maybe even a 24pitch.
It's the Binford Model 7500 trolling motor !!
wow that's awesome ! wish I could buy one for myself! that's supposed to equal 25 hp? wow.
Nice! What do you use for speed control, resistive or PWM?
For the naysayers, there are lakes were gas engines are not permitted. This would be ideal for those situations.
Ever heard of non-conductive glycerin cooling?
Well done! Runs very Nice!
Esta bonito pero si le hubiesen puesto un dinamo - alternador internamente para recargar la batería le darían mas durabilidad a la misma... piénsenlo..
I am impressed. The motor must get the air cooled somehow. What motor and size do you use? Thanks!
How is it cooled?
what is the tork for the mortors
Amazing you should try an air scoop on top of the box no water will seep in an air scoop on top and for the batteries a thicker gage wire would work just fine that way the cable doesn't get hot love the idea i want one hahaha
@rowen211 4 stroke or 2 stoke ive got a 5hp 4 stroke as an auxiliry for my rib
bigger gage wire never hurts my friend
How long the battery lasts????
anybody who puts work ,,imagination ,and brains ,into anything ,is worth a ,VERY WELL DONE comment
Great! I subscribed to your channel! I'm in shipbuilding!!!!
Nice work! That's a couple of automotive alternators, right? You can use 12 volt batteries I presume, which most people with boats have on their boat anyway. I'd like to see 4 good quality deep cycle marine batteries driving two of these on a bigger boat. If you use some sort of aluminum or stainless steel cover (maybe even repower an old outboard by just replacing the engine) you would surely get better heat dissapation . . . not that alternators aren't used to working in hot environments under the hoods of cars. I think an alternator could easily handle 130 degrees. They deal with 125 degree heat in Las Vegas every summer - millions of them (meaning all those cars out there, running in the hot sun at lunch time during the hottest days of summer).
Those aren't alternators, they are motors. Pretty different on the inside.
Can't use heavyweight battery stuff if you want to 'plane on water. Besides, non abused Li-cells last a lonnggg time, are half the mass and hold 4x the charge of lead.
These motors are permanent magnet so must not get too hot or they will weaken and fail. The trick is allow clean, cooling air, not salty water.
If you shorten the battery wires they will be able to carry more amperage with less resistance and less heat, therefore being more efficient.
Perhaps you may want to look at this technology on youtube.
Electric kart: world record with Linde E1
WHAT No cooling air for the motors??!! Maybe for short putts its ok but they need some fresh air and maybe even a fan pumping air to them.
Why don't you put each motor in a water proof case (tear drop shaped) and put them under the boat each with its own propellor?
I'm sure that's never been done!
How many HP for the motor
Great bit of innovation
what is the estimate cost of this motor?
Good one guys.................Great effort !!!
Wow thats some serious power !
What motor is the foot off of ?
Say, how much it costs, these electric motor, controller and battery LiOn
I like internal combustion better as well, as long as they make it clean - the electric power comes from combustion anyway, if you think about it - the power plant.
Europe has been running diesels for years as the primary source of combustion, and they beat gas hybrids for economy and efficiency. Plus, Canada has pollution from mining the nickel for hybrid batteries.
they can make biodiesel from almost anything organic with only oxygen and water as a waste product(even from sewage).
Very cool, if you had that motor on a smaller boat, 14' or even a 12' she would fly!
water cooled?
how much would you sell it for
Richardson bay??
Show me an electric outboard that uses a new hyper performance solar panel that works in the shade of cloud cover on a rainy day, and I'll be impressed. No killer batteries.
At this writing this video is 7 years old ...Marine Engine Designers have been trying to crack the code of electric powered outboards almost as long as there has been electricity. Heat dissipation and battery technology have always been and remain the two barriers that cannot be over come. So it remains to this day...
they h ave 25hp electric motors now
How long will it run on a charge?
Nice Trolling motor. I'll still stick with my Yamaha 250 Saltwater Series though.
Why not add alt to change to battery and longer on water without dead battery
Linc Qimiq alternater would bog the electric motors way down a drain the battery faster than it charges
Jason Stanfield I think it's not .. it's not hard spin
You can't create more energy than it's using. Friction and rotational mass from the alternator setup would drain the battery even quicker
scaled up homemade trolling motor. what's the big deal?
+shamu3838 Wheres the one you built?
+Tyler Luckenbill Which one? I gots a cuple duzen in my garage.
How many amps was it drawing?
Absolutely brilliant.
awesome motor what a power!
If you add one of those shark fins to the lower unit , you would stay on plane with very little power.
