We have the 8HP 48V Hangkai, Been running it for 2 yrs now in electric only clubs No issues at all. The one change we made was switching to Lithium batteries. We usually make long runs and Lead acid were good for half a day before losing power, Now we can run full power all day, No worries... .. Love ours
Thank you for your comment. I want to switch to electric also. How many amo hours do your lithium batteries need to run all day in that Hangkai 8hp 48v? I was assuming that I would need a minimum of 100ah & it seems like that costs over $2k & would be about 100 pounds of batteries. Any suggestions?
@@r.williamcomm7693 it would be 100lbs of lead acid/agm/gel.. Lithuim gets quite a bit more AH....crazy more...with the weight of 2 or less....and they are well sealed, dont buy into the "lithium catches fire in water" nonsense because they are sealed well...and will be inside.anyway...the problem uou ask???? COST COST COST COST
I am New to owning a boat!! I have the same motor from Amazon. On the site it listed the battery requirements as any 120ah deep cycle. ( Or at least that is what I gathered) so I bought the motor and a battery. When I realized I was going to need 3 more batteries, I figured it would be cheaper just to buy us a smaller electric outboard motor that can run off of 1 12 volt battery. I. My point have a brand new one of those motors if you want it I live in San Francisco I'll give it to you for 50 bucks come and get it
@@strawberryboones4780 would you ship it to me. I was just medically retired from the army and I have a small plastic boat. I have the batteries laying around.
I have this exact same motor. I got mine off ebay over 2 years ago it was a open box special I paid $250 for it. I use it in salt water for its whole life, I just rinse with fresh water after each use. I have replaced the shaft seal and gear oil once. I also stepped it up to a 67.2 volt battery over the 48 volt it works perfectly. Plus gave some slightly higher rpm, no overheating issues ever even over 90 degrees out in the direct sun. It is a little noisy for electric but full of torque. I think the motor is a great deal. I run a 32 ah 67.2v lithium battery from my surron e bike
I've got the same motor and everyone I've talked to that has one says you need to take the prop off and take the plate off behind the prop and add oil to the gears. I did mine and it's been running great. I can get two fishing trips before I recharge!
Yes , did the oil make it quieter? I have a four stroke gas motor and it sounds quieter. I have a 10ft 6in porta boat. Made of plastic . I really like it. Light and is quiet. My 5hp gas motor seems quieter than that motor. Adding 4 batteries would make boat too heavy in back. 4 batteries weights more than boat.! Lol. About 2 times as much. Boat motor is 52 lbs.
That makes sense, the motor was over working & boat not moving because gears were starved for lubrication. I also read thar a bronze bushing wore out in another comment. Always pull plugs for lubrication. Im a millwright though, second nature for me.
I use trolling motors to eliminate exhaust smell and noise. I bet twin 86 pound trolling motors would be quieter than this motor, and no heating issues. Also redundancy in case one fails.
I have a gas outboard, doesn't smell at all and is very quiet. Very smooth and pleasant running reliable engine.Lasts all day and I can just fill up the can and it's ready to go again. No heavy batteries to mess around with. Love it.
Nice video. I have the same motor. If you notice, it is a 5 hp motor with a 1200 watts power consumption. That does not add up as 746 watts equals 1 horsepower. So this is just over 1 and a half hp. It still works well enough for my light boat and I have two 48 v 100 amp hour batteries so it can go full speed for 8 hours.
I would love to open it up and see what motor and gearbox setup is in that. You could probably bolt the drone to a pole and get nice quiet thrust. Love the fishing boat, nice setup.
Thanks for the video review. Helped. Thought these would be cool for a small boat but I’ll stick with a minn kota for our John boat. I would not be able to handle the gear box noise.
Cool. Thanks for sharing. The energy density of gas (and diesel) is crazy high. I'm sure battery technology will improve and there will be some new motor and even boat designs, but gas can't be beat right now.
Not even close unfortunately. And what's more is about 91% (I think) of the energy is actually wasted in a combustion engine. So there's 9 times more power we aren't even using in gas and diesel fuels.
seen a couple of these out there in the bayou, most noticeable was the 300 pounds of batteries needed for a four hour runtime,they also seemed really loud, and the benefit of using a decent trolling motor to sneak up on fish is lost, some might be okay with the tradeoffs
You will love the longevity of an electric motor and the lack of messy fuels and oils . When you find the right motor for your needs , combine it with a nice lipo battery bank and enjoy the extra range for weight and maybe include a couple hundred watts of solar top up panels and you end up with a pretty functional rig .
Definitely not 5hp. 1200 watts is 1.6HP. An ammeter on the battery lead would at least give you an idea of the power consumption before efficiency losses.
I'm with you I don't think this is a option for any application other than lakes that don't allow gas boat motor ! I own a 24 volt Motor guide 70lb thrust Trolling motor and it moves my 21 ft Sundance V-hull Bay Boat 5 mph on my Garmin GPS and does it VERY QUITE and this is a waste of $$$$
Is the noise from the motor or the cooling fan? Next review could you include amp/hour battery specs and what this motor draws for time running so we can get an idea of range? I’m in South Florida so I’m interested to see how it does in the heat also. Thanks for putting out some info on this thing. So hard to tell if these things are junk or not.
Batteries are so heavy, it pretty much cancels out any possible advantage. I don't want a pile of lead in my fishing boat and weighing the rear end down.
Everyone comparing to gas CLEARLY missed where you said "electric only lakes". And clearly have never been a member. Just moved back to the SouthEast from Colorado and you got me fired up to join another club. Great video, ignore the haters, and 99% of us cant wait for the update. Have a great day!
That is quite neat how it’s a gas outboard converted to electric. The leg/lower unit at least. Probably the cowling/engine compartment too. I’m thinking the volt meter on top is replacing the OEM hole for the fuel tank stopper on the gas version of this. Anyone else notice the exhaust ports above the prop within the cavitation plate? I have a 2hp 2-stroke with similar exhaust location.
I have 5 Hp Hangkai on an 18’ Jon boat with front and read decks and aluminum floor carrying 5 batteries and a Foot control on the front and it will fun 4.6mph consistently
I took the risk two years ago. Same thing no reviews in English, however I don’t regret buying the motor. Faster then my minn Kota and great for electric lakes
Being from Georgia myself, I had to see what you said about it. I've been looking at these things for some time now. They ain't cheap!!! But I have pondered the thought of getting one on a new boat build. No matter what you find they all seem to make noise. This one seems pretty good. That set up would be great here in the Ozarks. 4 batteries is some weight for sure but you got to have it, I agree as well. Glad I checked it out!!! That's something I'm having to consider as well. I like your channel. You're information on this one really helped me determine the true pros and cons. Thanks for sharing 👊
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?
Thanks for the review. That noise would drive me crazy. Someone else commented that it might be from a gearbox, and it sounds to me like it might be gearbox noise. Expensive direct-drive motors like the epropulsion spirit 1.0 are much quieter. However, the epropulsion motor costs like $1500. I'm looking for a motor that's in a fixed position for my 22-foot sailboat. I'll steer with my rudder. I am looking for a motor that's quiet with a removable battery. I considered these Hangkai models, but after your review, I think I'll keep looking to find a quieter motor.
Looks like about 1.5hp to me. I’ve got some old air cooled outboards by cruise n carry and tanaka that only weigh 15-20lbs that put out 1.2hp and 2hp. They haul ass on a kayak.
So from what I’m seeing with these electric outboard’s it’s crucial to manage expectations. A good rule of thumb is to take with the manufacturer calls equivalent and cut it in half. For instance, if you had a 5 hp gas rig on your boat and wanted to replace it with an as powerful electric set up then you would want to get a 10 hp rated electric outboard. This seems to be true with all electric outboard manufactures as even the largest 50 hp Elco motor gives you 25 hp gas results.
The first thing I thought about when I saw it was the heat generated from the oil less electric motor like on an oil less air compressor. I'd definitely take the top off and cut a hole take a fan from a computer install it so it pulls the hot air out and put a louvre over the fan too protect it from the elements
Looks like they used the exact same leg and lower unit as on a gas outboard (note the exhaust outlet above the prop). I'd wager a fair chunk of the noise comes from the lower unit gears. You don't notice so much with a gas engine because all small gas outboards are really loud, but they do tend to make a bit of gear whine.
That's part of it. I've been messing with these Motors for months now, and did a complete teardown, gear and gasket replacement (after I destroyed my lower unit gears). The main issue with noise is the tolerances with the gears. The standard gaskets are not thick enough between the motor mount and lower unit, and also where the shaft connects right above the bottom gearbox, so when the bolts are torqued down the gears can bind up a bit. Put thicker gaskets and it'll be happier. Still louder than I want, but runs well with 4-5kw with a 20s lithium battery. Does 11mph in a 15' inflatable kaboat, being quite limited by the prop... Can't find good alternatives with more bite that fit.
@@AdamBrusselback ahh, insufficient gear clearance would do it! I bet it varies a fair bit from motor to motor too. Re: your propeller issue, I've recently been experimenting with 3D printing outboard props. My Mercury 3.3 has a nylon propeller from factory, so I thought I might be able to print something that is up to the challenge using carbon fibre nylon filament. I printed off a prototype in PLA to test the fit on the shaft last week, and decided to give it a run in a bucket of water to see how well the blades withstood the stress. Didn't go far above idle (water just started sloshing out of the bucket) but up to that point the PLA prop handled it beautifully. CF Nylon is quite a bit more robust than PLA, so I'm hoping that the final product will be good all the way up to full throttle. I'm designing my props using the Javafoil and Javaprop programs that are free on the web. They're fairly user friendly, Javaprop can take your use case and a list of foil sections and design an 'optimal' propeller blade automatically. Its built in foil options aren't the best for a plastic marine prop, but you can simulate others (I like NACA 16 series foils) in Javafoil and import them.
@@nerd1000ify Well, I typed out a longer reply, but it was eaten in the tubes before it made it to RUclips I guess. I appreciate the info on the prop software, and I have an mk3s sitting around, so I should really give it a shot. Would be fun to try some different profiles and materials out. These motors really are pretty terribly made, the metal is cheap and can be bent by hand pretty easily, and the tolerances between the three motors I have are all way different. They all have slightly different motor/controller combos too. If I could get my hands on a good supply of outboard parts, I'd love to design a mount for a nice powerful electric drivetrain on an existing, well tested lower unit....I just cannot seem to find a supply of those types of parts, and not for lack of searching. So that idea is on hold for now.
The gears in it is probably just cheap straight cut gears (also probably rough and tight) and would be the cause of all the noise. Even the high dollar Pete Jackson timing gear drives are loud,because they're straight cut gears. I'd just stick with a cheaper Minnkota high thrust trolling motor.There you'll have a resource for spare parts if needed...and not to mention a good warranty.
@@ede7208 Yeah it probably that too,the no oil I think it has more to do with shipping as to the reason they often don't add oil to engines an etc. Just say each motor uses 1 qt in the shaft.What's a ship carrying 1000 of these engines with a total of a1000 qts of oil weigh if each qt weighs between 1.5-1.7lb? A lot of extra weight they have to pay shipping on,plus the EPA regs if there is any on them coming into the US.
Another vid I saw with a similar looking motor (maybe the same) was also loud. He later found out there’s a sealed oil chamber at the bottom by the propeller. They’re not supposed to ship from China (or anywhere) with it filled. This guy didn’t get a manual or directions that mentioned it. You should check and post if you find the chamber & unscrew it.
sounds like a cheaper brushed motor rather than brushless my minkota 30 30 pushes near 5mph so prop quality probably is a thing I'd mid mount your batteries for better weight distribution so the hull isn't trying to climb uphill the water wasting your speed with up force unless you're getting a higher HP electric to get more 🏓 paddle power ,shoot id just strap 8 to 6 regular trolling motors back there with modified props for best performance and maybe get her to plane but yeah you're gonna need more batteries more powah deh better maybe throw some cheap solar panels on the deck to float charge the batteries so when not moving or just fishing at anchor ⚓🔱 your at least getting a bit of charge or at least covering the battery drain of fish finder can always wire in paralell to charge of a 12v smart car charger overnight then swap to om series mode for the faster prop speeds but less range🤷🏻♀️😇 good luck fishing out there 👍 glad you're trying to save the environment with electromagnetic radiation pulses 😂♻️🎣
Some RC boats have water cooled motors just by sucking water from the inlet and looping around the motor with copper tubing and back out the boat. Just use a water pump.
very good observations. The 3 hr range of batteries is also dependent on water conditions. That 3 hours can become 2 hours when the water gets choppy and the wind picks up. Having a second battery is the easiest solution. I have a canoe so I can paddle but with a larger boat you better have a backup motor!
I’m glad I went with the $200 3.6, if you didn’t have to go electric id say just grab that thing I hit 8mph w 500+ lbs that little motor is reliable af with about 60hrs on it.
Thinking about purchasing one of these for my 12 John boat. I fish mainly electric only lakes in GA, and this seems like a worthwhile buy for the price.
@@GeorgiaBassmasterfrom what I’m seeing and talking to the manufacturers it’s best to manage expectations. A good rule of thumb is to take rated hp and half it. Even the Elco 50hp gives 25hp results when factoring power, weight and ability to plane.
24 or 48 volt will supply the same power, the difference is how many amps go through the cables. Twice the voltage means half the amperage, and it's your amperage that is limited by cable size primarily.
@@mikediamond353 Precisely what I said about amperage. Not sure of the specifics in how it uses either/or, but since the motor was listed for a specific power output, (meaning the wattage rating stays constant), then 24 volts would require twice the amperage. Watts = Volts x Amps.
Thank you. Pounds of thrust, or horsepower, or the one you like: watts. I think there is up to 10% gain or drop, but that gear noise is hurting on my ears
The issue with these will be the cheap nylon gears- (hence the noise), and cheap mosfets, you can get lucky and they will last years; however if you try to never run them at full power for long periods you will avoid the mosfets overheating and burning out the controllers. Or you can add cooling of some kind to also extend their lifespan. Having had a decade of learning the shortcomings and strengths of cheap chinese E-technology, I am definitely investing in 2 of these bad boys.
Nylon gears; like Moms 1955 sewing machine?!? Well to get our SJ 23 down the ally and into the wind I'll take my chances. But I'll look for brass gears in the meantime.
5hp is probably over rated, it's probably closer to 2 or maybe 3...the reason it could move that size boat at a decent clip is because electric motors make more torque than a gas engine of higher hp. So the torque gets it moving, HP is what gets it moving at a higher speed. As with anything EV powered, the problem is the batteries. A 5hp gas engine is easily $1500, so a $400 electric sounds good...until you add the price of 4 deep cycle batteries (or even more so, a 48v lithium pack) and then you are back near the cost of a gas engine, but with more weight. Still, it is a bit quieter and when fishing, it can be nice to stop...fish, twist to move to the next spot, fish, twist ect without having to stop/start an engine every time.
I would like to know how long it can run on batteries? Obviously it depends on the size of batteries, but let's go with your typical set up. PS. You should add that when you put batteries in series, they should all be the same size capacity batteries and definitely use deep cycle batteries.
I can see that for a trolling motor but not a main motor. I get that some lakes dont allow gas motors but you’ll be spending all day getting to your spot instead of fishing.
So I’ve done a bit of research on these. Yes, for the money they will outperform a 24v trolling motor. Is it 5hp equivalent? No, not even close. They are loud, considering it’s electric, and not as efficient as they should be. The market is there for a better option than this, and it won’t be long, considering the dip in price on lipo batteries… there will be substantially better options at a similar price point soon. Wait, and get a better unit. Be patient, electric will catch up.
Mine also eventually crapped out. Idk if this makes sense but it seems like the motor went out of phase with the speed controller. Like when I apply throttle it would move half an inch and lock up. It was fun while it lasted. Definitely not 5hp. Otherwise it would have been able to just barely plane out my inflatable dinghy. But it wasn't even close.
I don't know anything about these motors so if this sounds stupid... Did it ship with or does it use lube in the foot? Could that be the source of the noise? Is the range good enough to run another motor in the same 4 batteries. Twin engines would be cool in a nerdy type way. While you're at it build a jack plate for em. lol
I have one of these. I run it on 4x 115ah batteries. It runs all day and works well. Bad bits: The gearboxes can fail. There is a bronze bush that wears out. I machined up an improved one. These motors are quite noisey considering they are electric. They are not great quality but what do expect for the money?
@@sambrose1 Wouldn't surprise me, other Hangkai engine's on YT were all shipped with NO gear oil at all.... imagine how that sounds... a bit like what we hear here.
I can’t believe it’s the electric motor making that noise. Doesn’t sound like motor noise, but unlubricated gears. Fill the foot with gear oil as it probably shipped empty.
Go down to 24 volt. It will be quieter and run twice as long. The H.P / torque will not change much. You have room for a 100 watt 5.78 àmp solar charging system on that rig.. Solar eorks excellence for going out all day on the water.
I wonder if they could make this with duel props for quicker take offs . I seen pontoon boats with a electric trolling motor up front with two props for steering. One on each side of the pontoons.
I did see a YT video of DUAL e-outboards on a cruising sail boat (35-40 foot). It may be a few years before counter rotating matched motors ard available.
Chinese electric motors do not last very long because the copper motor windings are very thin and over time the vibrations will break them. And it sounds like it doesn't have lube in the gears or maybe the bearings which Chinese are known for leaving them dry and you have to lube them before using them.
Could you open the top and give a good look around of the insides? I thought about ordering one of these and installing a better electric motor for more speed, that one is 1000w 48v, I'd like to add a 2000w 48v but don't own one
Haha let me have some fun with that thing, I had my sons old mx350 electric dirtbike that was supposed to only do 14mph I had it doing 42mph with a 150lb rider on it lol
Yup that motor sounded loud even in the video. You didn't mention those batteries weigh over 200lbs. That's like having Bubba sitting on your transom. Also, one deep cycle battery is $200. That's $800 on top of the cost of the motor.
@@jonboatmorava9115 Yup, not to mention $800 worth of fuel would run a 5hp motor for 20 average seasons. You would be lucky to get 10 seasons out of the batteries, then you'd be out buying batteries again.

That set up would be great here in the Ozarks. 4 batteries is some weight for sure but you got to have it, I agree as well. Glad I checked it out!!! That's something I'm having to consider as well. I like your channel. You're information on this one really helped me determine the true pros and cons. Thanks for sharing 👊
$400 for a new electric OB isn’t cheap?
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?
Thanks for the review. That noise would drive me crazy. Someone else commented that it might be from a gearbox, and it sounds to me like it might be gearbox noise. Expensive direct-drive motors like the epropulsion spirit 1.0 are much quieter. However, the epropulsion motor costs like $1500.
I'm looking for a motor that's in a fixed position for my 22-foot sailboat. I'll steer with my rudder. I am looking for a motor that's quiet with a removable battery. I considered these Hangkai models, but after your review, I think I'll keep looking to find a quieter motor.
Looks like about 1.5hp to me. I’ve got some old air cooled outboards by cruise n carry and tanaka that only weigh 15-20lbs that put out 1.2hp and 2hp. They haul ass on a kayak.
So from what I’m seeing with these electric outboard’s it’s crucial to manage expectations. A good rule of thumb is to take with the manufacturer calls equivalent and cut it in half. For instance, if you had a 5 hp gas rig on your boat and wanted to replace it with an as powerful electric set up then you would want to get a 10 hp rated electric outboard. This seems to be true with all electric outboard manufactures as even the largest 50 hp Elco motor gives you 25 hp gas results.
Two words: backup oars. Appreciate the review brother!
I've never had a problem with a gas powered outboard. Been running one for 25 years.
The first thing I thought about when I saw it was the heat generated from the oil less electric motor like on an oil less air compressor. I'd definitely take the top off and cut a hole take a fan from a computer install it so it pulls the hot air out and put a louvre over the fan too protect it from the elements
That’s definitely something I need to do!
@@GeorgiaBassmaster it would be easy to wire in since voltage display is right there
Great idea!
Watch the video before you comment, he said there is a fan and you can see the vent slots. A computer fan would never keep that engine cool enough.
@@bruceringrose7539 I did watch it that's why I said what I said. Why you so tense ?
Looks like they used the exact same leg and lower unit as on a gas outboard (note the exhaust outlet above the prop). I'd wager a fair chunk of the noise comes from the lower unit gears. You don't notice so much with a gas engine because all small gas outboards are really loud, but they do tend to make a bit of gear whine.
That's part of it. I've been messing with these Motors for months now, and did a complete teardown, gear and gasket replacement (after I destroyed my lower unit gears). The main issue with noise is the tolerances with the gears. The standard gaskets are not thick enough between the motor mount and lower unit, and also where the shaft connects right above the bottom gearbox, so when the bolts are torqued down the gears can bind up a bit. Put thicker gaskets and it'll be happier.
Still louder than I want, but runs well with 4-5kw with a 20s lithium battery. Does 11mph in a 15' inflatable kaboat, being quite limited by the prop... Can't find good alternatives with more bite that fit.
@@AdamBrusselback ahh, insufficient gear clearance would do it! I bet it varies a fair bit from motor to motor too.
Re: your propeller issue, I've recently been experimenting with 3D printing outboard props. My Mercury 3.3 has a nylon propeller from factory, so I thought I might be able to print something that is up to the challenge using carbon fibre nylon filament. I printed off a prototype in PLA to test the fit on the shaft last week, and decided to give it a run in a bucket of water to see how well the blades withstood the stress. Didn't go far above idle (water just started sloshing out of the bucket) but up to that point the PLA prop handled it beautifully. CF Nylon is quite a bit more robust than PLA, so I'm hoping that the final product will be good all the way up to full throttle.
I'm designing my props using the Javafoil and Javaprop programs that are free on the web. They're fairly user friendly, Javaprop can take your use case and a list of foil sections and design an 'optimal' propeller blade automatically. Its built in foil options aren't the best for a plastic marine prop, but you can simulate others (I like NACA 16 series foils) in Javafoil and import them.
@@nerd1000ify Well, I typed out a longer reply, but it was eaten in the tubes before it made it to RUclips I guess. I appreciate the info on the prop software, and I have an mk3s sitting around, so I should really give it a shot. Would be fun to try some different profiles and materials out.
These motors really are pretty terribly made, the metal is cheap and can be bent by hand pretty easily, and the tolerances between the three motors I have are all way different. They all have slightly different motor/controller combos too. If I could get my hands on a good supply of outboard parts, I'd love to design a mount for a nice powerful electric drivetrain on an existing, well tested lower unit....I just cannot seem to find a supply of those types of parts, and not for lack of searching. So that idea is on hold for now.
specs of your batteries and the time you can run your set up would be good to know in your follow up review
Great motor. $1000 for motor, battery's, wiring to 4.5 mph! I'm sold
So am I, lots of small elec only waters here.
Extremely loud for an electric and seems very underpowered for 5hp
I was thinking the same thing. I'd probably take it apart and find out why it's so loud...that noise sounds like the loss of mechanical energy
It’s a 5hp motor on a loaded down 16ft boat it’s not gonna be a powerhouse
The gears in it is probably just cheap straight cut gears (also probably rough and tight) and would be the cause of all the noise.
Even the high dollar Pete Jackson timing gear drives are loud,because they're straight cut gears.
I'd just stick with a cheaper Minnkota high thrust trolling motor.There you'll have a resource for spare parts if needed...and not to mention a good warranty.
Probably no lube in the gears and other parts. Chinese expect the owners to lube them because they are too cheap to do it themselves.
@@ede7208 Yeah it probably that too,the no oil I think it has more to do with shipping as to the reason they often don't add oil to engines an etc.
Just say each motor uses 1 qt in the shaft.What's a ship carrying 1000 of these engines with a total of a1000 qts of oil weigh if each qt weighs between 1.5-1.7lb? A lot of extra weight they have to pay shipping on,plus the EPA regs if there is any on them coming into the US.
I think that trolling motor would move that boat faster than that 48 volt motor
Great review- appreciate it! Was surprised how loud it is
Another vid I saw with a similar looking motor (maybe the same) was also loud. He later found out there’s a sealed oil chamber at the bottom by the propeller. They’re not supposed to ship from China (or anywhere) with it filled. This guy didn’t get a manual or directions that mentioned it. You should check and post if you find the chamber & unscrew it.
sounds like a cheaper brushed motor rather than brushless my minkota 30 30 pushes near 5mph so prop quality probably is a thing I'd mid mount your batteries for better weight distribution so the hull isn't trying to climb uphill the water wasting your speed with up force unless you're getting a higher HP electric to get more 🏓 paddle power ,shoot id just strap 8 to 6 regular trolling motors back there with modified props for best performance and maybe get her to plane but yeah you're gonna need more batteries more powah deh better maybe throw some cheap solar panels on the deck to float charge the batteries so when not moving or just fishing at anchor ⚓🔱 your at least getting a bit of charge or at least covering the battery drain of fish finder can always wire in paralell to charge of a 12v smart car charger overnight then swap to om series mode for the faster prop speeds but less range🤷🏻♀️😇 good luck fishing out there 👍 glad you're trying to save the environment with electromagnetic radiation pulses 😂♻️🎣
I saw another video. Evidently the gears aren't lubed and you need to do this yourself. Just an FYI
Some RC boats have water cooled motors just by sucking water from the inlet and looping around the motor with copper tubing and back out the boat. Just use a water pump.
&400 for motor and at least $400 for batteries . I’ll keep my 9.9 2 stroke but cool video.
Best review I've ever seen hands down.
very good observations. The 3 hr range of batteries is also dependent on water conditions. That 3 hours can become 2 hours when the water gets choppy and the wind picks up. Having a second battery is the easiest solution. I have a canoe so I can paddle but with a larger boat you better have a backup motor!
It will still last 3 hours but youre not going to get as far, if the motor is ran full power in both situations
I’m glad I went with the $200 3.6, if you didn’t have to go electric id say just grab that thing I hit 8mph w 500+ lbs that little motor is reliable af with about 60hrs on it.
I might have to grab one of those!
Running time is less than half. Remember wherever you go you must return with a little saved for emergencies
Excellent video!!! Thank You 🙏 for taking your time and sharing this video
Thanks for making this all I could find was foreign reviews!
Thinking about purchasing one of these for my 12 John boat. I fish mainly electric only lakes in GA, and this seems like a worthwhile buy for the price.
I sure wish you would publish the AMPS and WATTS draw please! That would tell us the battery travel time.
the motor sounds stressed
compared to name brands, they are probably running it at max rpm so i doubt it will last as long
I’m thinking of trying the 60v 10hp version of this. I’m not sure if these emotors are the equivalent of their gas counterparts.
They aren't at all.
@@GeorgiaBassmasterfrom what I’m seeing and talking to the manufacturers it’s best to manage expectations. A good rule of thumb is to take rated hp and half it. Even the Elco 50hp gives 25hp results when factoring power, weight and ability to plane.
24 or 48 volt will supply the same power, the difference is how many amps go through the cables. Twice the voltage means half the amperage, and it's your amperage that is limited by cable size primarily.
I'm not sure what you mean;
How can 24 volts supply the same power? The motor windings are different.
@@mikediamond353 Precisely what I said about amperage. Not sure of the specifics in how it uses either/or, but since the motor was listed for a specific power output, (meaning the wattage rating stays constant), then 24 volts would require twice the amperage. Watts = Volts x Amps.
Thank you. Pounds of thrust, or horsepower, or the one you like: watts.
I think there is up to 10% gain or drop, but that gear noise is hurting on my ears
@@mikediamond353 Yeah, didn't much care for that noise.
You might want to check if the noise is related to needing to add some oil.
The issue with these will be the cheap nylon gears- (hence the noise), and cheap mosfets, you can get lucky and they will last years; however if you try to never run them at full power for long periods you will avoid the mosfets overheating and burning out the controllers. Or you can add cooling of some kind to also extend their lifespan. Having had a decade of learning the shortcomings and strengths of cheap chinese E-technology, I am definitely investing in 2 of these bad boys.
Nylon gears; like Moms 1955 sewing machine?!?
Well to get our SJ 23 down the ally and into the wind I'll take my chances. But I'll look for brass gears in the meantime.
Thanks for the video, learned a lot, order mine soon.
4:16 saw that strap and thought .... You're gonna need a longer extension cord than that. LoL'
5hp is probably over rated, it's probably closer to 2 or maybe 3...the reason it could move that size boat at a decent clip is because electric motors make more torque than a gas engine of higher hp. So the torque gets it moving, HP is what gets it moving at a higher speed. As with anything EV powered, the problem is the batteries. A 5hp gas engine is easily $1500, so a $400 electric sounds good...until you add the price of 4 deep cycle batteries (or even more so, a 48v lithium pack) and then you are back near the cost of a gas engine, but with more weight. Still, it is a bit quieter and when fishing, it can be nice to stop...fish, twist to move to the next spot, fish, twist ect without having to stop/start an engine every time.
I would like to know how long it can run on batteries? Obviously it depends on the size of batteries, but let's go with your typical set up. PS. You should add that when you put batteries in series, they should all be the same size capacity batteries and definitely use deep cycle batteries.
Any way to check rpm vs max rpm? Prop sounds like it could use some adjustments.
That boat weighs a ton with everything in it, i'm surprised it moves at all, 4 batteries alone is crazy
I have 3 in the front as well 😂
I can see that for a trolling motor but not a main motor. I get that some lakes dont allow gas motors but you’ll be spending all day getting to your spot instead of fishing.
My electric lake it takes me an hour to get from one side to the other. No gas motors allowed and it’s a $1,500 ticket.
Prop needs to match a boat weight and shape. this thing is louder than my 140hp 4 stroke.
They have 48 volt lithium batteries on eBay that would definitely make that boat go faster and they keep getting cheaper.
Go lithium ion if not for nothing else the weight differential with lead acid.
So I’ve done a bit of research on these. Yes, for the money they will outperform a 24v trolling motor. Is it 5hp equivalent? No, not even close. They are loud, considering it’s electric, and not as efficient as they should be. The market is there for a better option than this, and it won’t be long, considering the dip in price on lipo batteries… there will be substantially better options at a similar price point soon. Wait, and get a better unit. Be patient, electric will catch up.
Mine also eventually crapped out. Idk if this makes sense but it seems like the motor went out of phase with the speed controller. Like when I apply throttle it would move half an inch and lock up.
It was fun while it lasted. Definitely not 5hp. Otherwise it would have been able to just barely plane out my inflatable dinghy. But it wasn't even close.
I don't know anything about these motors so if this sounds stupid... Did it ship with or does it use lube in the foot? Could that be the source of the noise? Is the range good enough to run another motor in the same 4 batteries. Twin engines would be cool in a nerdy type way. While you're at it build a jack plate for em. lol
I have one of these. I run it on 4x 115ah batteries. It runs all day and works well.
Bad bits: The gearboxes can fail. There is a bronze bush that wears out. I machined up an improved one.
These motors are quite noisey considering they are electric. They are not great quality but what do expect for the money?
I was thinking the gear train could use a little love from the sound of it.
@@sambrose1 Wouldn't surprise me, other Hangkai engine's on YT were all shipped with NO gear oil at all.... imagine how that sounds... a bit like what we hear here.
Seems pretty noisy for an electric outboard, but at that cost pretty damn cool! Finally the future is here. Nice vidwo. Thanks
It's the only electric (anything) that is louder than gas! For the life of me, I can't imagine how an electric motor can make all that noise.
@@Bob_Adkins I really don't understand the noise. Maybe someone can enlighten us.
I can’t believe it’s the electric motor making that noise. Doesn’t sound like motor noise, but unlubricated gears. Fill the foot with gear oil as it probably shipped empty.
That’s a pretty cool little motor man!
Go down to 24 volt.
It will be quieter and run twice as long.
The H.P / torque will not change much.
You have room for a 100 watt 5.78 àmp solar charging system on that rig..
Solar eorks excellence for going out all day on the water.
lol
good idea
I wonder if they could make this with duel props for quicker take offs . I seen pontoon boats with a electric trolling motor up front with two props for steering. One on each side of the pontoons.
I did see a YT video of DUAL e-outboards on a cruising sail boat (35-40 foot). It may be a few years before counter rotating matched motors ard available.
5hp input = 3725 watts. 3725 watts / 48 volts = 77 amps draw at full power. Get a shunt and measure it out of curiosity
Chinese electric motors do not last very long because the copper motor windings are very thin and over time the vibrations will break them. And it sounds like it doesn't have lube in the gears or maybe the bearings which Chinese are known for leaving them dry and you have to lube them before using them.
Could you open the top and give a good look around of the insides? I thought about ordering one of these and installing a better electric motor for more speed, that one is 1000w 48v, I'd like to add a 2000w 48v but don't own one
Haha let me have some fun with that thing, I had my sons old mx350 electric dirtbike that was supposed to only do 14mph I had it doing 42mph with a 150lb rider on it lol
So, when you kill those batteries, can your buddy motor to the gas station for a can of electrons?
I know the vid is 2 months old but I wonder if there was any grease is that foot. Maybe that is why it was so loud.
Tripled the value of that outfit
Yup that motor sounded loud even in the video. You didn't mention those batteries weigh over 200lbs. That's like having Bubba sitting on your transom.
Also, one deep cycle battery is $200. That's $800 on top of the cost of the motor.
Funny how the cost of batteries is never brought up.
@@jonboatmorava9115 Yup, not to mention $800 worth of fuel would run a 5hp motor for 20 average seasons. You would be lucky to get 10 seasons out of the batteries,
then you'd be out buying batteries again.
I use 4 12v 35 amp hour Gel batteries. $45 each and I went 6 hours fishing the Ithaca day with a quarter of the charge used.
How long do you get out of the batteries.
Cool video man.
The noise is prolly from the gear fit and finish. Can't expect super well fitting gears for that price ....
I recognized that ramp immediately.
That little outboard is pretty cool!
EPropulsion Is the Best so Far....You might like to field test one of their units, eh????
Not bad. Wonder what it would w a newport vessel nk180
My 19 foot square stern canoe can take up to 6.5 horse motors. This thing would be unbelievable. Only issue is too many batteries.
LOOK OUT BEHIND YOU!!!! Pocahontas jumped on board!!!
Inertering review. Yes it goes forward well but how good is the braking compared to a traditional outboard?
I bought my tahotsu 8hp for that price at a local pawn only was I had to buy parts for it
the guy 4 comments below is right about the oil in the gear box you should check it out
90° days in Georgia that thing is going to be water cooled with the humidity
How easy is it to find a Prop replacement?
You should try a quad or quint setup.
Carroll county! We’re neighbors. Is that Fairfield? Probably not, looks too muddy, possibly lake buckhorn? Just curious where that is.
Did you check the gear lube behind the prop?
Time to order some Ebike battery for this.
