Best I’ve seen on TH-cam so far. Great job 👏🏻
It's not market-ready yet but with some development it could - and frankly should - be the mandatory replacement for outboards under 10 horsepower. Less noise, no meaningful pollution as long as the seals on the shafts are good, no fuel spills.
This would be absolutely insane on the kayak, would love to see if you can make that into a video 😉
I think that would be too heavy. Could do a canoe with a transom
Holy smokes. That thing rips!
That’s awesome! Don’t forget about “trim”
Good effort for a good weather day out. Definitely not for rainy day or swell conditions..
Thank you!
It’s not as strong as I had hoped but it does a really good job. It’s about twice as powerful as an 86lb thrust trolling motor. I wouldn’t want to have either of my little dinghy’s in swell conditions lol. But if I was, I wouldn’t have much of a problem with this motor.
@1:47 I recognize that move! I do a LOT of wacky and potentially dangerous projects. That "Hmmm...Maybe I should shield myself" moment. :D
Lol the last thing I wanted was to have the motor blow up and shoot shards of metal into my face or the prop come off and helicopter into my junk haha.
So much more peaceful to fish like that
WOW! That's brilliant. Well done. I'll subscribe and check your other videos to see if there is an update.
I got this hangkai 60v 10hp motor, can i do a smaller upgrade to like a 4000w or 5000w electric motor by just swapping the motors? What else would need to be modified? Thanks!
make your prop shaft 2 pieces connect them with silicone coupling vibration will be gone
Which montenergy motor is this? What controller are you using?
Please go further into the technical info. I have 2 Mont Energy 1004 mounted in my boat. Getting it wet in April.
They now make a 60v 10hp version
The 10hp electric HANGKAI model is listed as 60V 38A(rated current) = 2280w (rated as 2.2KW)
Whilst the 8hp electric HANGKAI model is listed as 48V 50A(rated current) = 2400W (again rated as 2.2KW)
What is the reason for the discrepancy? Is the 10hp model more powerful?
Wow man this is awesome...great inginuity!!!!
Good job
3hp out of 40 amps is good, with 5 batteries at 80ah or 400 ah total you could get up to 10 hrs cruising which would be amazing. I am planning on switching from lead/acid batteries in my EV to a modified 130lb 1250kw Prius battery . Like the video!
Far as I've found, a Prius battery is 4.4 or 8.8 Kwh. and that's straight from Toyota.

@@LkOutMtnMan was your idea to step it down a whole bunch to 48V for e.g. the Hangkai?
@@0xKruzr Yeah I had the idea to regroup the cells to get 50 volts by using 7 cell groups of 6 cells ea. 28 cell groups at 6.5ah per group is 182 ah but it weighs 82 lbs I think. Maybe less without the added electronics, not sure.
@@LkOutMtnMan trying to figure out how much battery I'm gonna need in advance for my build - thinking two 86lb trolling motors @ 24V each, plus a 12V cooler, some lights, maybe a fan. my first instinct is a 24 to 12 step-down off four 24Vs would probably cover the accessory 12V load but I dunno how much a transformer like that costs.
Battery wasn't problem? 60v 5 pcs 12v 150ah leed acid battery or lifepo4? Nice job anyway but 3000 4000 watt speed must be too slow as well according to 8000 watt. How about speed according to watt used?
your wires are way to small for them amps bud
the last boat burn down ?
lol yeah, in the beginning they were way to small. I changed them out with 0 gauge wire after the positive lead melted off the motor.
nice selfbuild--- but to loud....underwaterdirectdrive is the only one.
With that much potential power i would like to see double the size inflatable. Maybe even the planing hull one and a large enough lower unit to fit a speed prop onto.
I like 👍

What is your limiting factor? When you run full throttle, does the motor seem really loaded up? I had a similar setup and found the motor ran at 50A all the time (48v) with no fluctuation… I think I was under-propped… wondering if that’s your issue here, that tiny prop is spinning full RPM, but since the motor isn’t working hard, it never moves up near the rated 8kw.
The trick I found is matching parts… I used a ‘90s 2-stroke 15hp EVinrude as my donor engine and lower unit, which is identical to the evinrude 9.9hp (just different carb). In any case, I’ve got a 48v brushed DC motor that is rated for 100A continuous with unloaded 4800RPM. That was the trick… I needed a motor that was about the same power and still ran the same RPMs, to balance the expected power and torque to the prop.
We have a DIY water cooling jacket around the motor that lets us run wide open without overheating the motor. It’ll pull as much as 125A at 52v continuously, and pushes our 18ft skiff at 13mph.
I think the biggest problem I have is cavitation, I can only go about 75% throttle after that the water starts boiling and the prop stops pushing water. I have a different setup now, I just haven’t had it out on the water yet to test it out. I’m definitely doing something wrong though, the fastest I’ve gotten my 10 foot dingy to go was only 7 mph. Thank you for the advice! I’m going to look into that.
why didn't you put all the options in the handle to bypass all the toggle switches by using a handle from a used trolling motor?
I eventually did switched the throttle setup to something like what you’re talking about it just wasn’t on the actual handle. In the beginning I was mainly just in testing mode.
@@adamofmosttrades7970 That's Awesome Glad it worked out for you, I am going to try using a washing machine motor with a basic motorcycle twist handle on and have it run underneath the dingy I have so that i can use it in front of me, so i don't have to sit all cockeyed lol Did you see the boat this kid built with foam and a bicycle frame lol it is awesome the motor he uses will blow your mind it is almost like a jet boat he has to be doing at least 40 mph here is the link th-cam.com/video/JlJu6Z6I4-w/w-d-xo.html
Nice!!!
No audio???
Did you nuke your battery like we did?!?!
Is 60v safe in water?
Would be interesting to see the the full performance if this amazing motor... If you would have the posibility to push 133Amps into it and solve the cavitation problem with a on top fin... Torqueedo at 48v 1000amps seems to have a better performance and a nicer trace on water (probabbly because of optimisation and no cavitation... Having the motor outside is a little bit noisy but that can be solved with a insolation box...very nice experiment... Thanks for sharing and the comunity will appreciate if you have any news to post... :)
Super
What type of battery are you using for the motor? How often do you have to charge it? Will a regular small car battery activate this motor or is it susceptible to damage from the water?
I’m using a 60V 64AMP lithium ion battery setup that I actually built myself. It will last all day without needing to be charged. A regular small car battery wouldn’t be anywhere near enough voltage. You would need to string 5 of them together in series for it to even turn on the speed controller.
@@adamofmosttrades7970 quite a small battery for its power output, I presume you dont run it at full throttle for long? thats just 3.8kwh/storage which would be 20 minutes or so of full beans
@@davidrose1675 the lake I use it at is small enough that I’ve never had a problem, I do mostly drift fishing but it’s basically using the motor to go all the way to the other side of the lake drifting then back to where I started and repeating for 8 hours. I actually built a spare battery just in case though. Also, I’ve been having a cavitation problem when I go past
75% throttle.
Do you have a list of the parts I can buy to do the same?
In The description
Oh i cant wait for electric personal watercraft. The noise of even 4 strokes still ruins a day on the water.
could I get this kind of speed on a kayak if I gripped the drive shaft with the chuck of a DeWalt cordless drill?
Hey, What was the original Hangkai motor like?
What is a price of that motor and how can i get in india
It’s a “manta 2” motor, I paid around $600 for it. I’m not sure where all they ship them, but I doubt you would have an issue getting one. I got mine on eBay. It took about a week the receive it in the mail.
Is it brushed or brushless motor?
It’s a brushed motor.
@@adamofmosttrades7970 Thank you.
Hi,it's a very inspiring job.Can you give more information about the motor like rpm and is there any reduction before prop?I made my motor for inflatable kayak you can check it on uploaded videos (36volt 500watt brushed dc with direct drive but thinking for add 2:1 reduction for better performance))Thanks.
Thank you, it’s still a work in progress project but it’s getting there. Im using a Manta 2 8000w motor powered by a 60V 64A lithium ion battery. The motor is rated at 4400 max rpms. The way I have it set up is direct drive 1:1 it does really good I just need to work on cutting down cavitation if I go full throttle it sounds like a hot tub because of how bad the cavitation is right now.
@@adamofmosttrades7970
love it! What top speed are you getting and what's the range?
@@johnbinnie5697 John, right now I’m only getting about 7mph… but that’s about to go up quite a bit because I’m in the process of modifying my lower unit to fit a MUCH bigger propeller as well as adding a cooling system so that it won’t burn up the motor minutes into running it. The most I can run it at is about 75% throttle so I’m also working on that and I haven’t really tested run time at that amount of throttle. I can tell you that the 60v 64A battery that I built will last an entire day of fishing and I’ve probably used the motor 15 times since I built it. Hopefully I will have this done soon so I can test it out and show my progress. Im hoping by next weekend I’ll have an update.

What is the reason for the discrepancy? Is the 10hp model more powerful?
The horsepower ratings are more marketing gimmickry than actual hard data. They are estimates that represent how the motors compare to gas engines under cherry picked conditions. Actual horsepower can be calculated at 746 watts per HP.
🤘🏻😎🤘🏻
And the range is 20 minutes 🤣🤣🤣
Sikkkkkk
Mit 10 PS keine gleitfahrt. Das ist schlecht. Ich fahr mit 5 PS Parsun 26kmh im 3.2m schlauchboot
Way too heavy for a small boat. Will rather run my 5hp 2-stroke
It is kinda heavy but it’s a must have on the lakes where you can’t use gas engines.
I guess the guy can't talk.... a mute?
What does it matter if I talk or not ? I’m sorry if you didn’t understand what was going on in the video without someone talking the entire time. All I’m doing is showing my ideas to help inspire others, I didn’t realize talking had to be done to get my point across.
I agree. I like to hear a voice
