Electric Boat Conversion
Вставка
- Опубліковано 24 вер 2021
- Watch me as I convert this old, non-running, gas-powered outboard motor to use an electric motor powered by a battery.
The outboard is a Johnson (Evinrude) 25 hp mid-nineties model.
The motor I used is 3000 watts, bought on Amazon.
The battery bank is 72V (6 x 12 cells, 20Ah)
Gas to Electric conversions for boats will be huge business opportunity in next few years. Kudos for your vision and leadership! ~tgb
Mate great idea to E the motor, But as you were making the drive connection I could see it was not going to be balanced, Suggestion, get the drive coupling made up by a machine shop and have it balanced, , then you will have less of an inssue in the forseable future
bro, nice job with the conversion! have a machine shop do the shaft connector. that thin metal sheet you're using will eventually shear off. btw, always remember to bring a paddle. just in case. 😁
12:39 all the happy kids and one happy maker ☺
Great build and video
Now all you need to add is the sound system to make loud motorboat noises! ;)
GREAT JOB & Video!!! 👍👍😁😎
Well done 👍 great job,
Real cool idea man! Powdered toast man shirt great stuff right there.
Dude, I'm inspired. TY
Good job
Nice work
this is awesome
Awesome no pollution 💕
Good job.
Beautiful family.
Good luck with future projects.
What are the characteristics of the motor and the controller?
Very cool! I bet that freaks people out when they see an old gas engine being so quiet! You can get more people on a small boat when you don't have a heavy gas engine...and the ride is much more enjoyable without the sound of an engine. ♥️🙏
It's awesome seeing people's reaction to this. Definitely nice to have a quiet running system, though it's not exactly silent. But you can have a conversation while underway! It's also nice to not need a big smelly gas tank on board. Thanks for the support! ❤
You are very smart !
Aw, thank you Auntie Margaret 💓
I have exactly the same motor sitting in my garage, I was wondering if it would be enough to power a boat, now I know :)
great work! But i am pretty sure you are overloading the boat capacity in Ontario. LOL ..
Part numbers would be nice, as would a wiring diagram.
Thank you for the idea
Awesome work Mike! Now all you need is a hydrofoil to tow behind that boat!
Can't wait to try it out!
Haha yeah! It is definitely the future project list!
I so want to do this but never done anything like it . What power out put do you need ? How much does one need
Got that many questions I canny think lol
Awsome project well done
👍👍👍😜🏴🦕🦄😁🤞✌️
It’s the way to go
Watch the video the house 8n the back round looks like a windshield and it looks like a diferant boat, that is a trip. I had to look carefully to see that. But good job on the project figured you would do it .now it would be nice if you would put out so e stats on how long it will run and how fast is goes.
Awsome ! Are you still sastified with the result ?
Great video without long drawn out junk, . Looks like a thought out conversion. thanks for posting. CANADA
Thing that impresses me most about this build is the Powdered Toast Man t-shirt...what kind of motor did you use, & what kind of batteries are those, & what's the device it's connected through?
It says in his descript, just didnt mention the controller.
Отличный мотор
GREAT !
Thank you for the video!!! Fine!
Tell Mike
1) what is the gear ratio of your gearbox of the old motor?
2) What propeller did you use?
I believe it's a 21:12 ratio (or 1.75:1) and the propeller is the stock one that came with the motor.
@@Watchmikework , Thanks for the answer.
I would love to know how far those batteries let you go. I'm gonna have to try this too!
It depends on a lot of factors but with our boat on a calm day we were able to go about 12km. Good luck with your build!
I used an impact socket as a coupler. I drilled it n filled it with mig weld
How do you put the motor in reverse? By controller or the gearbox on the outboard ?
Nice stuff mate, I've put a comment but can't see it here, so I'm doing another one, I am doing same sort of thing looking into bldc motors for this same purpose but quite liked the outcome of your project, do you still have links of this material that you have used or can you share the model of motor and controller spec model/link something that helps to get hold of the same gear, it seems to work fine, I have a Jonhson 9hp to do the same job. Thanks in advance for any help you might give 👊
Thanks for your comment! The motor and controller came as a kit from Amazon.ca:
BLDC 72V 3000W www.amazon.ca/dp/B07KR2FN89/ref=cm_sw_r_apan_i_HCZCR3HR0Q2MK2Y48Z0C
And the batteries are 12V UPS lead-acid. There are tons of options for batteries and I am hoping to upgrade to lithium eventually for greater range. Good luck with your project!
Where did you get all the parts i have a non working Johnson want to do same. Thanks you
I would love to know how much your conversion cost. What did the batteries cost?
What sort of top speed do you get out of that?
Awesome video but to many kids in a small boat very unsafe
Nice project, is that Bonfield Ontario?
Yes indeed! Good eye 👍
How much time you can ride with your this battery s??
Hay pocos motores verticales electricos, los comunes son horizontales y se dañan en poco tiempo al estar forzados, el resto bien
I’m gonna set my house boat up with something like this duel motor. Won’t go fast but will go free
Love it! I also charge this boat with my solar grid so you are right about it going for free!
@@Watchmikework my house boat has 400 watts on top. But room for 16 more. Some one just invented a super power panel that’s like 750 watt or 1400 watt. And said they’re cheap to make. My thought. How much power do you need to go down river. I’m gonna set a generator in get rid of gas engines. I only need 50 hp times 2. And lithium packs to charge. This way I got back up
@@Watchmikework my goal from Pittsburgh to Mississippi then to a nice calm lake
Great work. Very creative. I do have a question.
The coupler for the input shaft, when you initially tested it under a load, I noticed a slight wobble due to balancing issues. Did this have any adverse effect throughout the rpm range as far as vibration goes?
New Sub 🙏🏻
The vibration is somewhat noticeable when I have my hand on the throttle, though it doesn't seem to affect performance too much... but I imagine it would decrease efficiency. Ultimately it will likely cause bolts and things to come loose though.. would definitely be worth trying to balance the coupler to correct it. Thanks for noticing this!
@@Watchmikework The vibration will also wear the bearings out in the motor and drive shift.
Nice job 👍 I got a tr20 bass boat I'm wanting to electric power but I just can't figure out what to do. It's such I big boat I'm sure I'll need some kind of 48v motor. If anyone has any ideas please let me know thanks
It's possible! The options really depend on your budget.. check out the eTolly channel, he's got a huge, electric cabin-cruiser, powered by 48v. Lots of useful info there. Also the Sailing Uma channel has an electric sailboat that they used a 48v forklift motor to power. Super inspiring.. good luck with your project!
Great video I would like to do the same thing to my outboard I have the same motor .Is it possible for you to supply a parts list. Martin
these OMC 20-35hp motors are so reliable and powerful for their size i have no idea why you would want heavy batteries on board only to go far slower and have far less range?
how do you cool the motor/controller? I am curious how hot it can get.
The motor can get super hot! I use a 12v fan, and added a water pump with some copper tubing to circulate lake water around the motor. I am working on a follow-up video to show these upgrades and will hopefully post it soon!
Where did you find the electronics and batteries for your boat i am wanting to do it toa 57 evinrude 10hp
The motor and speed controller came from Amazon as a kit (3000w/72v brushless kit), and the batteries are 12V, 20Ah sealed lead acid (DZM-20) and were bought on kijiji but can also be found on Amazon.
i'D RATHER JUMP SHOTS THEN THESE SPEED UPS, DAMN THEY GIVE ME A HEADACHE.
This is awesome! Where can I find those adapters for the electric motor and the outboard shaft? Much respect from Nevada! Subscribed!
Thank you! In my case I made my own adapter/coupler using spare parts, a grinder and a drill press. I had to cut the end off the crankshaft, which fits the prop shaft.
@@Watchmikework sweet! Thanks for the intel. I weld, so I think I’ll fab something similarly out of plate for my application, and weld the crank shaft end to it. What was that bit of hardware that you modified? Looked like a door clasp?
How fast is it on water? How long does your battery setup last?
It goes about 10km/hr at max speed. I've had it out for about a 6km loop, but it could likely go a bit further. These are cheap SLA batteries.. with a better system (lipo) it would have way more capacity/range.
I wonder if flexible solar panels on the hull would get UV reflected off the water
I was thinking about adding them on as a bimini top.. but hadn't thought about using the hull.. cool idea! 😎
You took the whole top cap off ,it is lighter that way . I would make a hand rail the way we do it down here ,is go take a peice of pve 2 inch cut one side and glass it in plCe.
Awesome stuff, that looks about the size outboard I want to convert as well. Battery weight will always be an issue. But I'm only In early stages of planning....
Nice work! I want to do something similar. Curious on how fast it can go and the range.
Yes me too
Yes me three
What battery charger do you use?
My old 12V battery charger seems to have disappeared so I’m open to suggestions.
I’m currently working on something similar for an old sports pal canoe.
I’m using the same motor but I’m mounting mine to a mud motor kit.
At first I used a cheap 72V charger that I got on Amazon. But it sometimes didn't stop charging even when the batteries were fully charged, so now I use a 12V charger and charge each cell individually. It's a NOCO genius 2A/4A and it works great 👍
@@Watchmikework thanks! I’ll look into it.
Completely forgot to ask in my first comment, but how long does one charge typically last for you?
@@chasbearden one charge has taken me about 6km. I suspect it could go a bit further (maybe 7 or 8km) but I didn't want to risk getting stuck somewhere on the water! (Also there were 8 people onboard) I generally use it for fishing so we go at pretty slow speeds for 2 or 3 hours.
@@Watchmikework thanks for the info!
I’m definitely more confident about operational range of the setup I’m building now. Since it’s mostly going to be just myself and some gear, it’ll be an interesting ride. I’ll see about posting a video once I get it all assembled.
@@chasbearden sounds cool, would love to see your build! Best of luck!
Hi, i am making an 3.20 meter long electric boat for a school projekt, do you recomend this Motor you used or not ? Does it still work? What was your top speed when alone in the boat?
I really like this video, very creative!
Yes! This is a great motor to explore the concept and get a working model without spending too much. It isn't super powerful, and won't win any races, but it got my 4.2m fiberglass boat moving at about 10 km/hr with 8 people in it. With me alone the top speed is around 12 km/hr. I imagine with a smaller, lighter boat and perhaps some gearing you could go much faster! The main thing to watch out for is overheating the motor and wires. I will be adding a follow-up video soon to show a bit more details on the specs and problems I encountered, as well as improvements I've made since the first version. Good luck with your project!
@@Watchmikework thank you very much for answering !
Thats not a bad boat.
You need to come up with away to ballance your coupler.
Good point! I am going to try that
Hi, I have an old ski boat hull that had a 2 cycle outboard which I felt too guilty to run. So I sold the motor and put a Minn Kota trolling motor on there. That's quiet and better, but not really enough to push the 16 ft boat against a current or wind (i think). So I like how you did this. I'm inspired that maybe I can make my boat work again with electricity. I'll have to study a bit more before I can ask good questions, but thanks for your creativity and work in filming.
Guilty to run a 2 stroke????? What the ... I'll take it lol
Forget getting electric to save the planet .
Electric makes as much CO2 as gasoline when you factor in most electric comes from coal and gas supplies and making batteries makes a lot of CO2
Also in this time a fast Ski boat in electric would require TESLA telephone numbers to buy
Modern two stroke engines are nearly as clean as four stroke engines for emmisions .
Also modern two strokes don't mix oil with fuel in the fuel tank and operates more like the four stroked so oil pollution from exhaust is greatly reduced compared to old fashioned 2 stroke engined
In ten years from now when battery solutions are cheaper and work better than gasoline solutions for ski boats is where it is looking to be
Until then electric will be best suited to slow boats like for fishing on lakes where only electric is allowed to be used .
Converting a ski boat to electric suffers similar problems to covert it to diesel outboards .
Electric is very heavy and run times with battery at full speed will to keep battery smaller probably will be empty on 30. Minutes
Typical recharge times for that size battery are often north of 4 hours with 8 hour to be typical.Buyimg to three battery packs to 1.5 hours run time would probably exceed the sales value of you house and still require s gorrilla to lift in new battery and lift out spent battery every 30 minutes
@@shiningirisheyes You might want to fact check this, depends on where you live in relation to electricity generation sources. The grid is getting more and more renwable energy input and electric motors are clean at the point of use so are much better for local air pollution which is a big issue and they don't poor out oil and fuel into the river/ocean like dirty 2 strokes!
Also the amount of co2 you produce per charge from the grid and from battery degradation is way less than the co2 you produce burning equivalent fuel that also has to be mined, processed and transported in my understanding.
It looks like Canada
Why not just buy a trolling motor
Over time you are going to have a problem with the bearing on your moter .
place. Not the boat you showed us.
I wonder how long those batterries last on full throttle tho ive seen mamy stranded in the middle of lakes..
Can you give me that Amazon part number
BLDC 72V 3000W Brushless Motor... www.amazon.ca/dp/B07KR2FN89?ref=ppx_pop_mob_ap_share
Thanks. Did you have over heating issues
@@ThailandAmazing Yes I did have issues with heat! I added a 12V fan, holes in the case for ventilation, thicker wires to the motor, and a 12V water pump with a copper tubing coil which cycles water around the motor housing. I will be making a follow-up video for this project to show these things!
Small electric trolling motors are easy to set up. Just hang it and connect it to a car battery. Larger ones get complicated and don’t Lend to reporter. This is not a good time to convert to all electric. Why? BC we are in the infancy of this technology and the prices are out of site for the regular family. Example: Tesla Y = $60,000 … Camry hybrid $37,000 where is the savings?
Thanks for the comment. In terms of savings, the big difference I see is in long term maintenance. Electric motors require very little as compared to gas engines. (Regular oil changes alone!) Secondly, it all depends where you source your electricity. In my case, I charge this setup with my solar panel grid so it is basically free. And yes, trolling motors are super easy to set up. But this is more about exploring the capabilities of an emerging technology. In any case the entire thing cost me less than a working 5hp gas-powered outboard motor and I don't have to pollute my lake while I run it.
I come across oblivious people like you every day. Electric is only expensive if you get luxury prebuilt things. A tesla is very high in price because you have a car with a ton of expensive equipment you are paying for whether you use it or not. A camry is a cheap car and toyota is still idiots sticking in nimh cells in their hybrids. But ok, compare a much larger super high end vehicle to the cheap of the cheap camry hybrid. Either way, I just made my bike into a 10hp mid mount electric for $1000 total all in cost. I also rarely buy lithium ion cells for more than $80-100 / kwh of USABLE capacity. The cycle life of even the worst li-ion cells is 10x better than what manufacturers list @ L80 (life to 80% capacity) and they dont just die out of nowhere. Now onto electric motors. The one in the video here can be bought for about $200 on ebay as a kit with around 4hp (if you dont use lead acid batteries which suck having a huge voltage drop and only about 50% usable capacity). But if you are want more HP, there are a ton of outrunner brushless motors that can push 60hp peak for $600-800. Then speed controllers to match at $200-400. Hard to beat these prices even with gas engines. If you actually wanted to do electrics, finding these good deals is literally a quick google search away.
