Yup. Even if not covered in manual, should be pretty simple. Usually a lower and upper screw of some sort in gearcase. Remove BOTH. Put oil (any major lower unit oil should be fine) in the LOWER hole 'til it runs out the top hole. Then put upper bolt in, which will keep most oil from coming out bottom/fill hole while you take fill tube out and insert that bolt. I'll be very interested to know how, or if the loud noise is lessened (before and after db meter readings?).
@@richardwernst I wouldn't expect much difference of noise whether the gearbox is oiled. The major noise comes from the motor, as it is up out of water (not like ePropulsion)
I have a 2 stroke gas Hangkai 3.6 hp motor. The leg on your electric motor looks exactly the same as the gas. I really believe the sound will be reduced if you added oil to the gearbox as they are not shopped with oil. Good video none the less.
@@JohnMcNeely The lower unit needs to be oiled. There's a saying that Hangkai doesn't add oil to the gearbox by default. Luckily for my case it was oiled.
to be fair you should have tilted the non running motor out of the water. the E-propulsion with a 2 blade prop and motor causing way more drag than the hangkai.
I agree, lower units are different, props are different, drag may be significantly different, maybe not......but if it is, then that would skew the results.
Hi Wayne. I'm a subscriber and a friend. I enjoy your videos very much. I think you like we all do have your own personal preferences and biases and I think it showed a little in this video. You gave the check mark to eprop in the support category and failed entirely to tell the story of how support worked for you with the hangkai. I happen to recall that story Wayne. I think it sucks that you don't give hangkai the check mark there or AT LEAST mention what the resolution was (They just sent him a whole nother motor. He wound up with two for the price of one)
I understand why you picked that motor. I believe you already had it and it's similar in specs to the e-Propulsion. But Hangkai also sells an 48v, 8 Hp direct-drive electric outboard. It uses a 2200W 3000 RPM (50a at Wide Open Throttle) motor. They cost about $300-$400 including shipping; still a fraction of the e-Propulsion. I think they would make a better showing against the ePropulsion Spirit, the Newport NT300, or Torqueedo 1103. Regarding tge kull switcg, I nlike trollibg motirs where the throttle stays where you set it, the Hangkai electric motors use a spring-loaded throttle. If you let go of the throttle, as if you all out of the boat, the throttle return to closed. You use cruise control, it wont. I also have a second Hangkai that is a 60v 10 HP. But it's the same motor. It draws only 37a at WOT. I don't detect a difference in power between the two. The 60v version has a 60v controller in the head. You can't just connect a 48v battery. It wont work. But the 60v version will probably last longer. But more and cheaper battery options exist at 48v including ones with Bluetooth BMS. The direct-drive hangkai motors are much quieter. Cooling with the direct-drive motor is not an issue.
@@JohnMcNeely I have the motor you're talking about. it works perfectly fine. a thing I don't understand is why Hangkai seems to refuse to put in the fairly minimal (for them) work to let these things accept a standard remote steering cable and remote throttle arrangement. the 2200W one makes plenty of sense for a little center-console runabout type boat. they have more powerful ones that would be even better for.
Wayne, first thing is to use an air compressor to blow as much dust out of the Hangkai lower unit as you can - I would also use a strong shop vac to suck out anything that is left in there - then fill it with I think 90LB weight lower unit lube before you run it again - I think you will find it will be a lot less noisy and faster - run it in the water at least 15 minutes or more to get whatever dust is left in there into the lube - when you get back change the lube again and you should be good to run that for a lot longer before it blows up - I never would have run it dry, everything like that needs some kind of lube or grease just like your drill and grinders do or BOOM - this was a great vid and test as usual -
Awesome video. The average person can not afford the high priced battery and many people do not want to pay $1,500.00 for an e motor, but more people are getting evironmentally conscious. Great motors for older women too.
The market for the ePropulsion is folks who can afford it. Think a tender going out to a sailboat on a moring. The hangkai is really for low buck fisherman and jon boats on ponds. I don't see them overlapping at all.
I know it would be iffy to use the Hangkai motor, but I think there is cheaper way to power it, if anyone is willing to take the chance, than the battery that you suggest. I found several batteries on Amazon that are 25.6 volts at 50 and 60 ah that come with dedicated battery chargers that fit a socket built into the case of the battery. They have BMS ratings that match their ah rating, so 50 ah has 50 amp BMS and 60 ah has 60 amp BMS. They range between $200 and $229. They could be wired in series (at least 4 allowed, in the ones I found) and you would have a 48 volt battery/charger setup for as little as $400. No name batteries so it's as risky as the motor, but I wanted to put it out there.
I would be interested to see a full test of the model with the motor in the lower unit. Even for the price i don't think i could stand the noise of the gear box.
Greetings from southern Ontario Canada merry Christmas I came across an outboard motor that is operated by propane ? I can't remember if it was on RUclips 😮
Excellent video, and review. THOUGHT: are either of these motors rated for salt water? Seems like immersing an electric motor (ePropulsion) in saltwater is a non-starter, which could give the Hangkai another check mark on the matrix?
The ePropulsion are saltwater rated and many have been on sailboats for years. I have read that the Hangkai motors are 'supposed to be' but many of them have corrosion issues pretty quickly.
I've only got one comment. I would fail the Hankai for speed only because it is supposed to be a 5hp equivalent motor but it performs exactly like a 3hp equivalent motor. I'll stick to a 1975 Johnson 2 stroke that can push my 14' Amesbury Dory over 23 mph when needed and it only cost me $1,000.00 with electric and manual starting. Keep up the good work. I look forward to your videos.
I have been thinking of picking up a 12-14 ft inflatable due to the crazy prices for used total junk boats these days - you just save me money by not buying an electric Hangkai - I have a 12volt trolling motor I picked up in a pawn shop in Texas in 98 that would work fine in the places in the Florida Keys where you cannot run a gas outboard and use a gas outboard to get there or for a backup - I do want to see another test run after you put the lube in the lower unit -
Thanks Wayne. Your comparison with the battery cost used a figure of $1100 for the Hangkai. You need to shop better. I paid $215 total with tax and shipping for the motor. I was able to get (4) 50AH 12V Lifepo4 batteries for $220 with tax and shipping. Total: $435 or $600 less than you paid. If you’re going to go cheap, then GO CHEAP! I bet a lot more of your viewers would be interested in the Hangkai at that price.
Fully agree with you. I just bought a 48v 100ah battery with charger from Aliexpress at only CA$150. My Hangkai motor costed me CA$500+. So total less than CA$700 (i.e. $500). That's a huge difference to the $2600 for ePropulsion.
Good stuff, I recognize those waters! I've always wondered about these hangkai engines. They also have some interesting gas powered options. Merry Christmas!
Hi Wayne, would you think the Hankai would push me Leisure SL 23 as an emergency backup? I have an inboard diesel, with 2 24 volt batteries, so could connect to those. Thank you
You can buy a metal prop for those as the lower, like you said is used on many motors. It helps slightly. Also there are two holes on the lower where oil would seep up and out, and water seeps in. Add a good marine oil to the lower gearbox, if they have anything in them it is probably a coating of Vaseline. Also plug up those holes that I mentioned to keep the oil in and the water out. I also found the tiller handle on those is way too small to be useful. It's a $200 unsupported outboard, have fun and don't trust your life to it.
4 pieces of 12 V 60Ah should cost a maximum of 400 USD. It will be cheaper and have more Ampere. You can often find 72 Ah batteries for a similar price. A regular 12 V charger will do if you charge individually. The cost of cables is additional, but is small. Am I wrong here?
I think the boat is not big enough. I think that maybe the top speeds are so similar because you are hitting "hull speed" but don't have enough power to plane off and get faster than hull speed. A good comparison would be how many minimum watts (or amps) are required to maintain top speed.
You goofed. You should be comparing the Hangkai 4 cycle against the epropulsion. You seemed to have forgotten gear oil. Repeating the same mistake over and over then getting too mechanical with the review kinda sucks. One more thing. Lighters that work every time or Zippo fixes them free. = Reviews could be a lot lot less wordy...and stop shouting at us. .
The Hangkai website says it needs to have gear oil added.
I just bought one from eBay and found that the gear oil is actually already added. But it's always good to double check if you buy one.
Yup. Even if not covered in manual, should be pretty simple. Usually a lower and upper screw of some sort in gearcase. Remove BOTH. Put oil (any major lower unit oil should be fine) in the LOWER hole 'til it runs out the top hole.

You mean the lower unit? The electric motor doesn't require oil.
@@JohnMcNeely did you see where the motor is? obviously the vertical shaft doesn't magically produce horizontal rotation

Seriously try a 12v Newport trolling motor with an APC prop, I bet you get similar speed for like $500 motor, prop and lipo battery

Did u check the gear oil on the hangkai gearbox ?
I'm assuming it comes with no oil
Maybe that recduces the gear whine
I will be posting a video about this soon!
Merry Christmas Wayne the boat guy
Thanks you too! Don't work too hard and try to stay warm!!
@WayneTheBoatGuy thank you very much, thinks I got most of this week off. Time to get back at some chores
Wondering about efficiency which has a huge effect on range and battery size/cost required. Would you be willing to test wattage at equivalent speeds?
I'd rather DYI upgrade the Hangkai than over pay for the Eprop.
I would be interested to see a full test of the model with the motor in the lower unit. Even for the price i don't think i could stand the noise of the gear box.
Are these things rated by some kind of horsepower that I'm not familiar with? Because usually 1 HP=749 watts. So you'd need 1500W to even have 2 HP.
It's also comparing apples and oranges. Electric motors develop full horsepower and torque at zero RPM. Gas motors do not.
Great video, i was wanting a comparison video on these 2 outboard motors. Thanks Wayne.
Thanks!
Have you looked into prop upgrades like the APC props?
There's no room to upgrade to APC prop. This Hangkai motor uses 7-1/4 prop while APC prop is normally 8~10 inches

Sounds like an elrectric version of Chinese Water Torture! Epitome of getting what you pay for!
wayne you got to do same test om aluminun boat ,that boat is too heavy for those small motor,see is you can do that,merry christmas and god bless you
This boat allowed me to have both on the transom at the same time - but I will be playing with it some more in the future!
I think the boat is not big enough. I think that maybe the top speeds are so similar because you are hitting "hull speed" but don't have enough power to plane off and get faster than hull speed. A good comparison would be how many minimum watts (or amps) are required to maintain top speed.
eprop wins on quality but also on support, for when the quality isnt there lol
Definitely!
