That motor sounds like my grandmother's old Sunbeam electric beater when she used to whip cream when I was little. A weird sort of electrics+dairy smell would start wafting from the thing if you kept it on the high setting for too long. It's a very specific sense memory that goes with a very specific sound and your little motor triggers it.
Looks great! I did something similar with a slightly larger brushless motor with a 15hp Evinrude 2 stroke, and the takeaway I’ll share is to add a couple BIG fans to draw air through the cowling to cool the motor, ESC, and batteries. You’ll need it, for sure.
@@0xKruzr I'm thinking I'll do both, use the old water impeller pump to move raw water through a small computer radiator and strap a server fan to it, then I can use the ocean to cool the air that I use to cool the motor and ESC. I even have a 48V server fan that'd be perfect. basically aircooled+
You wouldn't have any info out there on build process/parts list for your conversion would you? Have a 15hp Evinrude 2 stroke that I'm looking to convert myself. Thanks
This project reminds me of the start of your adventures to electrify your catamaran when you were calculating battery and motor capacity. Cool project stay happy and safe
Yeah stay safe Simon ¹ Watching your long hair dangle inches from That high speed spinning motor was making me nervous But you da man! Great work. Very inspiring
I am doing an inflatable boat, Bris 430, and putting 2 2520w Haswing 5hp trolling motors on it, for main power. And replacing the props, to try to get 9mph, instead of 6 max due to prop pitch. I have, so far, 300ah at 24v batteries for it, and 4 320w solar panels. The solar panels will be a sun/rain cover , approx 7' overhead, for my fishing boat. It will be heavy, but I will still be way under rated capacity even with a couple of more heavy people. Life is an adventure, sometimes you just have to try something different, LOL!!! And thanks for the vid!!!
For anyone seeing this thinking they can do the same, be warned it’s the quickest way to ruin your ESC (motor Controller). Turning larger more aggressive props, especially to push an inefficient hull design, will load up the motors and likely cause component failure in an ESC as most are designed and matched to work with particular size props for specific applications with very little head room to handle higher loads. If you are going to experiment with props in an effort to increase top speed, you must monitor amp draw closely under all loading conditions to ensure you are not exceeding the ratings of the ESC or motor system.
For what it’s worth, Pauli Juppi (on youtube) did lots of experiments converting outboard motor to electric. He used his motors on his twenty something feet sailboat. All powered from the sun. That was pretty cool as well :) I would love to have your part list and the settings for the esc, that would be awesome.
@@dennisaalbers8851 do they though? During summer my 240w panel gives around 200w per hour. That battery pack is about 1kwh... So full recharge in about 5 hour.
that's awesome, great to see someone put together a cheap DIY electric outboard. but it seems like that motor is going to cook in an airtight enclosure running at full tilt. you may want to limit its max power, or put together something to throttle it based on temperature
@@findingsimon why? Air cooling sucks. This outboard already has an impeller that will draw up water. How about tightly wrapping the motor with maybe 3/16 flexible copper tubing and run this water through it? Use heatsink dope to help with the heat transfer.
After watching more of the video, it appears this thing spins the outside casing, which makes wrapping it in copper tubing problematic. Time to find a motor with a solid, fixed casing that can be wrapped in tubing to suck the heat away using the existing water impeller.
Thanks for sharing the video, I think there are a lot of boaters out there, such as myself, who would like to buy, or build, an electric outboard versus buying a new four stroke. I'm one of them, but I'm inspired by your build, I really think this is the future. Keep up the good work! Looking forward to seeing a 150 horsepower electric build on TH-cam!
That was awesome. I would daydream about buying a boat enough to actually do the ASA101-103. Retired a couple years back and stalled on the ASA104. But did get a junkyard alternator looking to convert it to an underwater sailboat motor. You're actually doing all this - hurray! I watch sailing YT vids all the time and really enjoyed yours.
You are correct in saying there electric outboards put out that much thrust ! I like your concept and thought in using a older 2 stroke lower unit , it makes sense to do that and cost effective ta boot ! I rebuild 2 stroke outboards and have a few of those units that the power heads a shot and to have a way of converting to electric at a reasonable cost is fantastic you dont need a water pump or exhaust housing just a sealed lower unit ! Mounting the throttle to run off the tiller handle should be easy >
" I don't know if I would call that a hundred percent success, but i'm still calling it a success." I would too Simon keep at it, eventually you'll work out all the bugs and you'll have what your shooting for.
I have several 70's era 2 stroke Evinrudes in the 100-135hp range. I have been considering a conversion. I want power. Real power. 100hp. Plane a 16-18 ft runabout easy. When the electric Teslas and Volts etc are a dime a dozen, I will find the cheap parts necessary. Forget all that programing junk. I want the rheostat/controller to be linear and in my hand, or under my foot. Hit it and you go.
A success for sure. With regard to the top speed: most outboards (IC style) have a top rpm of 4500 to 5500, it sounded to me that your motor reached a hard RPM limit maybe less than that. Something to look into (maybe a a courser prop). Re: forward battery pack/charger. Because your usage is constant, your "charge rate" to the motor would have to be the same current as running wide open (or close to it). It would seem therefore, that it would be best to not put any battery in the motor case and just run reasonable cables from the main battery pack to run the motor. With regard to electric motor ratings: There simply are no apples to apples comparisons. I am sure that these E-motor companies have found some configuration of boat and motor where their product compares favourably to a 10hp IC. probably not on a dingy but rather a large displacement hull. IC motor/prop combinations are a well known compromise to make up for the IC motor's very poor low rpm torque. An E-motor should work better with a larger and courser prop at lower rmp much like steam engines of yore. The engineering on most smaller output E-motors has not caught up to reality yet except for the very expensive ones like on Uma. Advertising is therefore based on theoretical possibilities rather than practical realities. I happen to have a spare ic hanging around that might make a great donor bottom end. It is smaller than yours being a 7.5 2 stroke (same as the 9.8) while your 9.9 will be the same as the 15 and maybe 20 for the same year. You should have a number of prop choices out there (even used) to try out... like I said above, if you have a 12 inch pitch prop maybe try a 14...
I selected this motor because it has similar RPM range as the two stroke gas motor that came out of this outboard. But the torque and power curves are really different. As far as I can tell, the power supply is the limiting factor right now. I'll try and address that in the next video.
This is huge! I think a lot of people could find ways to connect the motor to the lower unit. You could change the world by making a detailed video about how to set up the ESC for this application. It took you several tries which means a beginner won't be able to do it without exact, detailed instructions (possibly in the form of one of your videos), please!
Just googling man. I installed a driver and two different softwares, but only one of em worked with this esc. Followed instructions for basics, then just tweaked settings after googling what each setting was.
Great job. I have a porta boat and i love it. I wont take it into salt water because salt water is brutal on motors. . Pretty cool what you did. Mavw one day i will try electric. My motor will run for days on a gallon of gas. 5 hp.four stroke gets my boat up on plane. Top speed? 13 mph? Not sure. Its plenty for me.
this is a great idea. I'd like to get some more info from you: Can you link the specific motor and controler you used? What voltage is the battery pack you are running? (I am assuming 24v?) Thanks in advance!
Hi. Nice job. One question please: Why did you choose the type of electric motor where the entire motor spins, instead of the more common electric motor type where only the shaft spins?
@simon, you are gonna find a LOT of performance out of prop blade shape and pitch, and as well any trim control or trim-plane blade. were those paired with and engineered for the torque curve of that DC drive motor, i imagine MUCH AMAZING efficiency increase when paired with that motor. get some, and add it to that evinrude chassis. it will make a huge difference.
Simon, I am not sure how you found your way to my computer but I am glad you did. This is WAY KOOL! The electric outboard engine that you made is impressive. After my last spinal surgery I have lost some use of my limbs and extremities so I am not sure that I could pull off making one of these, though I would really love to. This would be great for the electric only, smaller lakes around here. It would be awesome to get some of my smaller watercraft on plane while everyone else is slowly trolling around. I would be very interested in purchasing one from you if/when you make another. Thank you in advance. 😁😂
If I ever had the drive, maybe I could laser cut some frames and make plenty of motors and controller types available. Just a quick weld up and then assembly.
You mentioned compatiple votage to your boat, 48 VDC ?? Great project video Just looked up and watched the CBC piece. Congrats, was a very nice piece on you
I agree with you stating that the marketing guys of electric outboards should not lie, but you building it for 700 USD didn't include your tools in your workshop. If you want to do a fair comparison, the 700 USD should be the total of what is available on the market, good to go for "diy" with plug and play.
Waiting for part 2. I think, just as you mention, that those small batteries cant deliver the amount of current as the motor requires. I would love to see an update with more batteries in parallell.
I started out thinking yeah I could try this... then I see you on your lathe, and then I see you sorting out electronic incompatibility issues - it's all a bit over my head!
You can man. I just googled it. And the lathe was largely unnecessary. Just did it to try and use my new gear. Could just jam the chopped bit of crankshaft into a drill and grind it down to shape.
I'm curious when you said you had to plug some hoses. What came to mind was the water pump line. If it's the case if you removed the impeller from the water pump it would solve that problem and in theory it would would reduce "some" friction and less friction is less resistance in the prop shaft. But then at the end of the video something hit me. You had mentioned that it was getting very hot or warming up very quickly. Would it be possible to get 1/4" soft flexible copper and make something like a very closely spaced cooling system like a hybrid between a radiator and an AC coil that could be designed to snap in next to or around the battery pack or around the motor (or both) and then unplug your water pump intake, connect to it and circulate cool water through it sort of like how a heat sink is used to dissipate heat. Whether it increases the batteries performance or the motors output at the very least on a hot day with a lot of use you may avoid something from melting down. I know my high end LED horticulture lights for my green houses have heat sinks to keep the ballasts from getting to hot and extending their life. If they work of the electricity/magnetism relationship couldn't it apply to electric motors that may heat up and lose efficiency. Magnetism increases as temperatures drop unless that only applies to super magnets but honestly I truly don't know but I do not if your heating up on just a short run it can't be good over a long run. I mean you have the source of recirculating a pumping coolant already there. Or just for the cool factor you can convert it to a live well pump through the side with a compressor hose type of quick release fitting lol. And no water ever goes up towards the cowling again.
Whats the best way to build something powerful? Can i get one of those cheap hangkai electric outboard motors say the 48v 8hp and just replace the electric motor? Or its not that simple....
The 2520w motors turn, underwater at 1450rpm, at 6mp. So utilizing the 1200w 630 rpm 5 mph props at 1450 rpm should give a prop pitch capable of 11.5 mph without adjusting for slippage ect. If I break the props ect., just take off easy. I'll just modify regular smaller outboard aluminum props with the right pitch ect.
Here's a tip. Your sponsors blurb came too early in your video. I know you thought you had a good Segway but making sure you keep new viewers engaged is more important.
Simon, there's a chance your mounting bracket is causing some noise and reduce the motor's overall speed. Let me explain why. Consider an out-runner motor like a helix : it sucks the air around. By putting two plates at a short distance, the sucked air is chopped and produce that characteristic siren sound. That phenomenon reduces probably the overall speed. Maybe a cage mount with distant stiles would solve the problem. I love your channel by the way! 👍
@@findingsimon Simon, I'm not talking about an overheat issue but just about air flow which: 1. generate noise 2. limits probably the max RPM and the velocity of the motor. Air is a fluid which creates friction and can reduce an overall performance, and this is not a legend. Engineer speaking. About your batteries, I suspect you use LiPo ones ? The overheating of LiPLithium batteries comes when the discharge is too quick. Iime is too high. You need a battery with a higher capacity. Raise the capacity until the battery stay cool while motoring at full throttle.
Another thing I like to know is can you build an alternator into one of those that would charge the battery as you're running it just like you wouldn't old car is that possible
Thank you for sharing…… I’m going to be adding this video to my list of “great information “ videos. You can’t buy Anything for $700.00 nowadays………. That will move anything on the water 💦 that fast. 🤩🤩🤩🤩🤩🤩🤩 That thing could make my “DIY” light 18foot trimaran go in the low 20’s knots 👍👍👍👍👍👍👍👍👍👍 😎
Yes most of the electric outboard/ trolling motor companies lie! Torpedo has very low efficiency, due to still being brushed motors. To start with you need Brushless bldc motors min or even ones with a cd/ac converter in the controller. The Haswings I got for $800ea on amazon, but you can also go to Haswing direct and get them a little cheaper. The are bldc motor but not that great of design, so efficiency is not the best. But way cheaper than the other premade options. These supposedly 5hp motors are left hand turn, but they can run full power in reverse and utilize a right hand prop. Haswing also makes a more efficient 1200w, supposedly 3hp trolling motor. But, it has a gear reduction and is right hand turn, these run at only 630rpm, so the pitch and is much greater in order to achieve 5mph. I already have a couple extra of these props that I will adapt/machine to the 2520w motors, they should be strong enough. If I don't get the 9mph I'll add the 1200w motor and change the prop on that one, LOL!!! May 8mph will be enough, I'll find out later.
how long before it overheats? Because that is one of the most important things when picking a motor. It should be able to run for an hour without melting.
Nice . Like ur style. Little machine shop nice to. I got a unimat db200 pick up few years back 500 it was like new dr had it n estate sale. Wooden box mill attachments. Might been used few times. Anyway pick up 2 hp Suzuki outboard doesn't run someone tried to make it electronic ignition. Took points out and stuff. But I got free and going go electric. Thinking of 20 v or 60v got DeWalt tools 4 6ah 20v, few flex pack 60v for big chainsaws weed eaters. Thinking about one then size motors so I could use DeWalt packs . Or salvage one my old 18v tools for motor run 20v packs not sure yet . Put it on kayak. Any back to video cool I like it . I'll be checking ur channel out looks very interesting. Hey u stay safe have fun . From ur ole hillbilly buddy .
you need to change the pot in the servo tester to a slide pot rather than the rotary one thats in it thats how i did it when converting a strimmer from gas to electric
Hi, friend. I have been using an electric outboard motor for a year now. made from a qs138 motor and a kelly 7275 controller. There is a video on the TH-cam channel. develops a speed of 38 km / h
How about a gear between the motor and the shaft? 1.15-1.33 to spin the prop faster. EV's have the low end torque, but nothing on the top end, so to make te boat as fast/faster than ICE, it needs more gear. I also heard the final drive being dry/ weared out. There's some more top speed to be found there too. And, the prop itself. When there's a lot more torque with less RPM, a different prop would also do the trick. And one more important thing: Heat management. Power creates heat, and that can easily destroy the whole build if not addressed.
@@findingsimon Great job putting that together. Don't forget to check the gear oil.. you don't want to get this thing all done just to junk the lower end. And maybe add a Whale tail to get it up on plane a little faster. Good luck.
Impressive, considering you didn't even attempt to match gearing/prop to the power profile of the motor. It just further proves the point you were making at the end of the video.
Just out of curiosity what's the hours you can get out of a battery if you run it hard all day and what's the cost to buy one please leave a message and let me know
Electric will have it's place as a standard some day, not now. Solar plays a great roll now with cruisers. Many now supplement their sail boats with electric drives powered by solar panels. That application will most likely become a standard very soon as many new sailboats offer electric drives...

Now that you’ve got it planing, last piece of the pie is getting it foiling.
The increased speed and range should be astounding.

I started out thinking yeah I could try this... then I see you on your lathe, and then I see you sorting out electronic incompatibility issues - it's all a bit over my head!
You can man. I just googled it. And the lathe was largely unnecessary. Just did it to try and use my new gear. Could just jam the chopped bit of crankshaft into a drill and grind it down to shape.
The motor will put out more power with more batteries in parallel. The voltage drop of the overtaxed battery is likely costing performance.
Ditch the background music entirely and I'd watch this channel every night. First time visitor. Can't stand the music, tho. Won't be back.
Thanks for the video. This motivates me to do this kind also!
I'm curious when you said you had to plug some hoses. What came to mind was the water pump line. If it's the case if you removed the impeller from the water pump it would solve that problem and in theory it would would reduce "some" friction and less friction is less resistance in the prop shaft. But then at the end of the video something hit me. You had mentioned that it was getting very hot or warming up very quickly. Would it be possible to get 1/4" soft flexible copper and make something like a very closely spaced cooling system like a hybrid between a radiator and an AC coil that could be designed to snap in next to or around the battery pack or around the motor (or both) and then unplug your water pump intake, connect to it and circulate cool water through it sort of like how a heat sink is used to dissipate heat. Whether it increases the batteries performance or the motors output at the very least on a hot day with a lot of use you may avoid something from melting down. I know my high end LED horticulture lights for my green houses have heat sinks to keep the ballasts from getting to hot and extending their life. If they work of the electricity/magnetism relationship couldn't it apply to electric motors that may heat up and lose efficiency. Magnetism increases as temperatures drop unless that only applies to super magnets but honestly I truly don't know but I do not if your heating up on just a short run it can't be good over a long run. I mean you have the source of recirculating a pumping coolant already there.
Or just for the cool factor you can convert it to a live well pump through the side with a compressor hose type of quick release fitting lol. And no water ever goes up towards the cowling again.
Whats the best way to build something powerful? Can i get one of those cheap hangkai electric outboard motors say the 48v 8hp and just replace the electric motor? Or its not that simple....
The 2520w motors turn, underwater at 1450rpm, at 6mp. So utilizing the 1200w 630 rpm 5 mph props at 1450 rpm should give a prop pitch capable of 11.5 mph without adjusting for slippage ect. If I break the props ect., just take off easy. I'll just modify regular smaller outboard aluminum props with the right pitch ect.
Here's a tip. Your sponsors blurb came too early in your video. I know you thought you had a good Segway but making sure you keep new viewers engaged is more important.
one of your problems could be the the lower unit has a gear reduction so to take full advantage of the electric power higher pitch prop might help
All prices end please link motor controller battery
Simon, there's a chance your mounting bracket is causing some noise and reduce the motor's overall speed. Let me explain why. Consider an out-runner motor like a helix : it sucks the air around. By putting two plates at a short distance, the sucked air is chopped and produce that characteristic siren sound. That phenomenon reduces probably the overall speed. Maybe a cage mount with distant stiles would solve the problem. I love your channel by the way! 👍
This thing is an out runner. Battery is my heat throttling issue right now. Case will have forced air cooling in V2
@@findingsimon Simon, I'm not talking about an overheat issue but just about air flow which: 1. generate noise 2. limits probably the max RPM and the velocity of the motor. Air is a fluid which creates friction and can reduce an overall performance, and this is not a legend. Engineer speaking. About your batteries, I suspect you use LiPo ones ? The overheating of LiPLithium batteries comes when the discharge is too quick. Iime is too high. You need a battery with a higher capacity. Raise the capacity until the battery stay cool while motoring at full throttle.
Another thing I like to know is can you build an alternator into one of those that would charge the battery as you're running it just like you wouldn't old car is that possible
Thank you for sharing……
I’m going to be adding this video to my list of “great information “ videos.
You can’t buy Anything for $700.00 nowadays………. That will move anything on the water 💦 that fast.

That thing could make my “DIY” light 18foot trimaran go in the low 20’s knots

Yes most of the electric outboard/ trolling motor companies lie! Torpedo has very low efficiency, due to still being brushed motors. To start with you need Brushless bldc motors min or even ones with a cd/ac converter in the controller. The Haswings I got for $800ea on amazon, but you can also go to Haswing direct and get them a little cheaper. The are bldc motor but not that great of design, so efficiency is not the best. But way cheaper than the other premade options. These supposedly 5hp motors are left hand turn, but they can run full power in reverse and utilize a right hand prop. Haswing also makes a more efficient 1200w, supposedly 3hp trolling motor. But, it has a gear reduction and is right hand turn, these run at only 630rpm, so the pitch and is much greater in order to achieve 5mph. I already have a couple extra of these props that I will adapt/machine to the 2520w motors, they should be strong enough. If I don't get the 9mph I'll add the 1200w motor and change the prop on that one, LOL!!! May 8mph will be enough, I'll find out later.
how long before it overheats?
Because that is one of the most important things when picking a motor. It should be able to run for an hour without melting.
Very cool! Please add a kill cord before anything else though!
Maybe a higher pitch prop? Probly alot of torque there. Could be more than your gas outboard.
Very cool project. Keep on learning!
Could you please send the list of parts, emotor and controller brand and specs. Thank you.
Nice . Like ur style. Little machine shop nice to. I got a unimat db200 pick up few years back 500 it was like new dr had it n estate sale. Wooden box mill attachments. Might been used few times. Anyway pick up 2 hp Suzuki outboard doesn't run someone tried to make it electronic ignition. Took points out and stuff. But I got free and going go electric. Thinking of 20 v or 60v got DeWalt tools 4 6ah
20v, few flex pack 60v for big chainsaws weed eaters. Thinking about one then size motors so I could use DeWalt packs . Or salvage one my old 18v tools for motor run 20v packs not sure yet . Put it on kayak. Any back to video cool I like it . I'll be checking ur channel out looks very interesting. Hey u stay safe have fun . From ur ole hillbilly buddy .
Bumping up voltage will give you more hp =speed i converted a s10 a few years ago hp = volts torque = amps/ how fast you get to speed
Can you increase battery capacity for longer fun? Still might be good to have the oars.
you need to change the pot in the servo tester to a slide pot rather than the rotary one thats in it thats how i did it when converting a strimmer from gas to electric
Any updates on this.thank you
Cool project, did you pull the impeller out of the lower unit? Drop the parasitic friction a little.
Hi, friend. I have been using an electric outboard motor for a year now. made from a qs138 motor and a kelly 7275 controller. There is a video on the TH-cam channel. develops a speed of 38 km / h
What is your channel? Dont see any videos in there
I love your modified outboard !
Damn I'm loving your channel !!!
links to parts?
Did you ever go any further with this? Can the motor take the heat of an extended high speed run without a fan?
nice project
Awesome.... It can run fast...
Any links to the hardware?
Inspiring stuff, you got me on something here
Bluetooth wireless controller from a used electric skateboard as an auxiliary throttle controller?
Woah. Not a bad idea.
I might have missed it but I didn’t hear how much voltage are you putting on that motor
Nice dog RR mix?
cedar bones pacific blood! You are a real west coaster now for sure!
How about a gear between the motor and the shaft? 1.15-1.33 to spin the prop faster. EV's have the low end torque, but nothing on the top end, so to make te boat as fast/faster than ICE, it needs more gear. I also heard the final drive being dry/ weared out. There's some more top speed to be found there too. And, the prop itself. When there's a lot more torque with less RPM, a different prop would also do the trick. And one more important thing: Heat management. Power creates heat, and that can easily destroy the whole build if not addressed.
This motor has the same operating rpm as the motor that came out. The main issue right now is a restriction on amperage from the little battery
@@findingsimon Great job putting that together. Don't forget to check the gear oil.. you don't want to get this thing all done just to junk the lower end. And maybe add a Whale tail to get it up on plane a little faster. Good luck.
Try a bigger prop. For all the Torque. And remember to set a cut off voltage.
Cut off voltage was setup properly, this motor would like a smaller prop honestly.
Where can I get a motor like this?
What about using a golf cart motor and batteries?
make up a pivoting rubber cam to turn the pot so you can use the original throttle
hadn't thought of using rubber, good idea!
Impressive, considering you didn't even attempt to match gearing/prop to the power profile of the motor. It just further proves the point you were making at the end of the video.
what speed controller did you use?
Just out of curiosity what's the hours you can get out of a battery if you run it hard all day and what's the cost to buy one please leave a message and let me know
Solar panel roof increase you get stuck plus charge while fishing
Hey Simon, I'm in Vancouver and would love to buy you a beer sometime and chat about your setup
Electric will have it's place as a standard some day, not now. Solar plays a great roll now with cruisers. Many now supplement their sail boats with electric drives powered by solar panels. That application will most likely become a standard very soon as many new sailboats offer electric drives...
