The electro motors are NOT inefficient. Electro-Motors are most efficient of all motor types. The reason why spending 2x more power is not resulting in 2x more speed is just physics! The faster the more resistance you get from the water. And the problem why you think it is inefficient, is because you are used to use fuel motors and there never care how much fuel is used at high speed, because the tank is so big. But a electro motor as such is much more efficient than a fuel motor.
You may want to rethink your argument. Power is power, and when they tellyou it's a 9.9 HP equivalent, It is not. The energy used is, but not the end result.
@@JG-mf1yk we have a 20hp honda and use it for long commutes, the eProp just can't do it. But we still use the eprop for shorter distances. Each tool for it's mission. I don't care what power they say it is. The end result is what counts. Imo the rating should be in kw and the eProp should be a 1kw electric motor... This equivalences shit is bullshit.
@@reversingentropy agree. I am trying to decide between a 9.9 HP Honda and a watt and sea hydro generator or the epropulsion Navy 6.0 which is supposed to do both. But, the battery weight is crazy. Any feedback on the Honda ?
@@JG-mf1yk we bought the 20hp because the 8, 9.9, 10, 15 and 20hp are all the same engine and same weight they just change carburators and ecu. It's about 48kg so far its been great starts first pull. We have a 3.10 zodiac rib and max speed so far was 22kts going very slow not plaining its 5/6 kts in both cases you can talk over it, so not very loud, its a 4stroke . Bad things, it's heavy we use the missen mast to pick it off the boat, we now need gasoline aboard, more difficult to explore shallows. But it opens up a huge range of places we just cold not get with the eProp mainly because of currents and wind. We almost didn't make it back to the boat with the eProp from dinner once because freak unforcasted 25kts wind picked up Plus the current from the river at 1kts we wore barely moving and mover backwards everytime a wave hit stronger. Not cool with kids on board. That day we decided to get a "real" outboard. Hope this is helpful.
Great video. More people need to see it. These are great motors depending on how you use your dinghy. We talked before replacing our dead Honda 2hp with Spirit OnePlus and realized that our only use is to push our tiny dinghy to and from shore at anchorages. Dinghy is too small to row comfortably with two or more and no room for a bigger one. This motor is perfect , eliminating gasoline onboard, starting issues, maintenance bad gas issues, etc. However, our friends with the same sailboat use their dinghy to venture miles beyond the anchorage and at high speed. This motor would not work for them. Also we liked the way you broke the review up into segments and introduced each one. Thanks again. Good info here for many more than have seen it so far.
Great video! I'm looking into an electric motor for my small inflatable catamaran (12ft) and I'm looking at this and the Torqeedo. I'm curious, is your motor the short shaft version?
You are very welcome. Bear in mind though we now have two outboards on board, the eProp and a 20hp Honda for when speed and range is the only way we could make the trip. Cheers
Nobody drives their gasoline outboard at full power, usually only at 60 to 75%. So the Newton meters on the shaft are far from what you imagines. However, an electric motor delivers the full newton meters from first RPM, while the fuel engine can deliver them the newton meters that you can read off at its highest speed. See datasheet. Okay at the highest speed with noise you not like. So is the realität. If you let two identical inflatable boats compete against each other, one with an 1kw electric motor and one with a 1kw fuelmotor, you will realize that the electric motor has already pulled the other inflatable boat away long before it has even made a few revolutions and it will never be able to compete against the electric motor. greetings
I've had my Spirit 1.0 for 18 months now and it's NOT been a good investment. Those blue plastic handles that are attached to the clamps (to fasten the Spirit to your tender) are incredibly weak. Mine have both snapped off despite the Spirit only having been removed a few times. The lead connectors, ARE a weak point just as the video shows. I've lost count of the number of times I have got an error code. There is not any way of adjusting the angle of the leg when in shallow water. But, for me, it's the throttle 'direction' that has caused the most stress. It's the opposite direction to a normal outboard and, after 40 years of petrol outboard use, in emergencies or when I'm in a rush, my muscle memory sees me twisting the throttle into reverse by mistake-which has led to some paint damage to my mother ship, a bit of skin lost from having to fend off a jetty and much embarrassment. The Spirit 1.0 is okay but nowhere near what it could have been.
One would forgive all that If only it could planne... But since its software there should be an option to reverse the throttle, i had only a few years of muscle memory and in the beginning it was very hard to get used to it.
Bought one of these. You mentioned you charge it up to 80%. But how do you know when it's at 80%? You have to connect it up to the tiller and shaft to see what it's charged too. Really annoying
Useful information for me, as I'm in the market for one of these. I'm not too concerned with speed, as the plan is to use it to get around the marina, and not worry about hitting thegas filling station. I have a low draft sailboat (Bahamas friendly), so for exploring, I could get a bit closer with the mothership so minimize the distance.
me gusto su video, tengo un epropulsion 1.0 hace unos 3 años y por el tiempo que tiene ya tiene corrosión y el otro día se a estropeado la batería, por tener carga 100% sin usar por 2 meses se degradado, desmonté la batería y vi que tenia dos celdas mal, una de ellas hinchada y 0 voltios, he pedido el recambio en aliexpres por 38 euros las 2
Thanks so much for taking the time to make your video. Some watchers will wish that you got your pros and cons discussed more efficiently, but I liked the slow pace of your discussion with the digressions, beach scenes and fish sandwiches. And I found most of your cons to apply to most all electric outboards and not to the ePropulsion specifically, which helps me keep it on my short list of motors as I do my research.
Nice video, worthy watch. We only use our dinghy to get to shore from anchorage we decided to get one of these as they are much easier to handle single handedly to transfer from our yacht to the dinghy. Much easier to handle two parts each about 10kg. No fuel spillage and smell, instant start, delightfully quiet, and much easier to control fwd and rev. I tend to run it at 400W max which is the sweet spot for our dinghy. It's each to their own on how they use their dinghy but for simple back and forth to shore I wouldn't go back to petrol.
If your boat's waterline length is 10 feet your expected hull speed is 4.24 knots, So, to go beyond that speed requires a lot more power to go just a little faster because of the bow wave.
Thank you for your detailed and informative video. I will point out, however, that your comments between 8:00 and 11:30 min. regarding the diminishing returns of increasing throttle applies to other power sources, not just electric. If you had a petrol-powered outboard, as you increased speed, you would burn a disproportionate amount of fuel. P.S. I saw in the news today that the ENTIRE COUNTRY of Portugal was able to operate for 6 days in late October / early November relying solely on renewables: hydro, solar and wind. That's quite an accomplishment and worthy of praise. Parabéns!
Hi. The difference is that with more power eventually you get into plane and then you use much less energy. In a few year i hope we will have batteries capable of supply the required power for plaining at an affordable price. About Portugal beeing 100% renewable for a while. It's very good but it still kinda sucks the reason was that there was weekend and holidays so industry was closed. At the same time lots and lots of rain to replenish the hidro and lots of wind. So yes very good but a loool more needs to be done. Cheers
@@reversingentropy The good news is that there are companies like eprop that are selling electric a fair market price and open to whatever battery deal you can get from third parties. The battery market is improving but slowly. I was also going to point out that your speed gripe is the hull not the motor. That hull design is extremely inefficient BECAUSE it didn't matter with a 15hp motor and high energy density fuel. That hull is simply wrong for 3hp. An appropriate canoe hull could double your speed and range.
@@reversingentropy Torqeedo now offers 5HP equivalent engines. I'm considering buying my dad the Spirit 1.0 EVO, since he only has a small 2.4m Dinghy that can get on plane with a 2HP Yamaha. For your boat, I guess you'd need the Navy 3.0 from ePropulsion or the Torqeedo XP S to get it on plane and move efficiently beyond 3 kn. ;) Nice to see an actual operation-review btw. and not only these videos where someone throws it on their boat for a few hours and only does a test drive.
@@SaabFAN86 the issue is never the motor power it's easy to make a 20kw 35hp equivalent that weighs about 10kg, the problem is batteries. To run a 5kw motor at half throttle for one hour takes 2.5kw + losses and that is heavy and expensive. Batteries are getting better all the time so let's hope for a revolution soon 😅
@@reversingentropy That's why I mentioned the Torqeedo XP S. 1.6 kW from a 1.425 kWh Battery is quite the achievement. But once the boat is up on plane, the required power is probably close to 500 - 600 W, but at speeds in the range of 12 - 14 kn, which yields quite impressive ranges again. At least in theory. Anyone out to prove this? :D
Great video! thank you;) After watching it, now I guess a good test would be to check if you can get 3.6 nautical miles on a epropulsion elite throttling at 200W too.. if this is true, than profit :D
you are comparing this electric outboard to a fuel powered outboard. you bark epropulsion even though the same "defects" are in all electric outboard motors. many people only have the option of using an electric outboard motor, because in many lakes, for example in Finland, it is not allowed to drive with fuel-powered outboard motors. I understand that it's good to compare an electric outboard motor and a gasoline-powered outboard motor, but you can't talk about epropulsion, you have to talk about electric outboard motors in general. if you compare epropulsion, you have to compare it with other electric outboard motors. people who need an electric outboard want to see videos on what would be the best electric outboard for their budget.
I understand what you are saying. But I only have an e-prop and nobody gives me anything for free. So I compare what i bought, intelligent people like you will understand that the short comings apply to all electric outboards. Cheers
This video is jibberish..... I have owned and used the Spirit 1.0 for over 3 years on a highfield classic 3.1. It is a game changer, get the fast charger, I also have a solar charger.
Well - nice video! You pointed out the downside of the whole elctric drives ....with a brushless motor without gear, you´re already on the better side 🙂 You can just calculate the hull speed (displacement speed) for your boat...and thats pretty where you´re heading with your effective speed. Trying to get faster will just burn a lot of power for nearly no extra outcome. I got a fishing boat (4m fibreglass reinforced plastic) got a small brushless motor (Zebco Rhino BLX 70) which is on a 12V AGM battery (kind of like car battery) - THIS is a heavy battery...weighs about 20kg ..for maybe 2-3 hours of driving at 3,3kts. The Spirit got the "light weight"-Version of a battery, trust me 😅 Its a pretty decent concept for short ranges on a sail boat, short trips on a lake...for landing on shore with a dinghy you got the problem with the expensive battery. Maybe they develope some locks for motor and battery...this would be a useful extension
3.5 hrs to recharge the 2 bars (6 miles) you did in your test? Or is the 3.5 hrs for a full charge from a "dead" battery? If I misunderstood, how long did it take to recharge from your 6 mile trip? Thank you!
Hi. It was two and a half hours to charge the 2 bars that we used on the trip. However it seems the charging speed drops as it gets full. Like in electric cars, its 0 to 90 in two hours and then another two from 90 to 100... Seams like ita similar
The way charging works is that the fuller the battery is the slower it needs to go in order to charge safely without damaging the battery. That's why going from 10 to 80% on a phone or outboard or anything is super quick but 80 to 100% takes longer than 10 to 80 did.
The effect you are seeing with speed (velocity) versus power is about right. Drag follows "cubed law." If you need 200 watts, for example, to go 2 knots, you will need 2 X 2 X 2 (8 times) as much power to go 4 knots (assuming hull speed doesn't become a factor). The difference is: a gasoline outboard doesn't have a power meter, so you can't see that effect, but it's there also. It looks like you are doing a little better than the formula says you should, probably because the prop becomes more efficient at higher RPMs.
@@reversingentropy No generational shift will make it plane, you simply need a more powerful engine to do so and also a propeller made for higher speeds. The EProp Navy probably could but planing is better with gas engines as they work with higher rpm.
@@Black-March I wouldn't be so sure about that. I envision a higher density battery that will allow for a 5 to 8kw sustained for a few minutes without taking a huge hit. You only need high power to get from displacement to plaining. There are a few manufacturers that managed to do it but it's not in outboard form. Remember a few years ago your phone had physical keyboards. Tech moves fast.
@@reversingentropy You're talking about a significant overclock to the engine which would risk damaging it. And also it's not simply a matter of having a little more power for a moment or two, it's that electric engines are designed to work with low RPM high Torque, while regular outboards work with smaller props and higher RPM.
That's what we do. Simple, quick and easy. Probably not necessary as most boaters are well off enough that they don't need to steal. But the temptation to acquire an extra $1500 battery could be tempting... whether for backup or an emergency.
I have a guess here...that RIB is not going up on plane. So can it be considered a full displacement hull when using the electric motor? Optimal hull speed for a 9 foot boat in that case would be 4.02 Knots. That would explain why the sweet spot is 200/250 watts. Trying to push it past hull speed just sucks up more power with very little increase in speed. Again...just a guess.
Your video was helpful as I consider electric for our dingy. Sure want to get gas off the boat (and love the quiet) and am willing to go slower if that's what it takes. Thanks
Thanks for taking the time to make this video. I appreciate all your thoughts on the motor. I just started using my new motor and I’d like to know about cleaning and storage. When I take the motor off my dingy I notice that water drains out of a couple holes on the side of the motor, just in front of the propeller. After a few hours or a day of running around, do you rinse off the shaft/propeller unit, or do you go a few days or weeks before cleaning it? Have you done anything else to keep the saltwater from deteriorating the lower unit? Do you feel like the lower unit could just live on a storage bracket and be constantly exposed to salt spray? Thanks again.
Im not sure what is the correct procedure, but I'm sure its not what i do, because i have never cleaned or rinsed the motor 😂 when we are cruising it stays on the dinghy full time, and i raise the dinghy out of the water on the davits every time to prevent growth on the dinghy bottom and motor. When we a not cruising i keep the motor in a locker. I have never cleaned it, but now that you mentioned it i think i will start to do it before storing it. Cheers
Thanks for this contribution. I learned things, enjoyed it. I'm thinking about getting one of these, so it was good to hear your thoughts after using it. Really like the way you put cool visuals in. Get one of them hairy microphone covers for the wind!
Am I understanding this correctly? When on shore there is no means to lock the battery to the rest of the engine so one is forced to either lug 8kg around or risk it being stolen??
Yes, there is no built-in lock. However, you might be able to lock it using a chain and a padlock. Nevertheless, I would not feel comfortable leaving the battery on site even with a training padlock so I just take my battery with me.
@@reversingentropy - I find it staggering that no one in the design stage had the foresight to ask why the user would want to lug 8kg around when they reached their destination and provide no means of locking the battery in. It makes me wonder what other practical considerations they were too shortsighted to see, UV damage maybe from months sitting on a pushpit? Seems more like a product for recreational fishermen maybe rather than use on a tender. If so they’ve colossally misjudged their potential market.
1kw is 1.34 hp Google it there NOT 3hp there poorly made try going against the current and you will turn around you won't make it .. I have one and they are good for ponds
You are incorrect. Just today i had to carry 60 meters of 10mm chain plus a 1.5kw windlass plus me 100kg against 4kts current. It was slow but steady. I will exchange ease of use no pull chord to start no gasoline no noise no smell no maintenance etc for slower performance any day. That being said I'm hopeful for more powerful versions to be the norm in the future.
@@andrewstone1868 the 3hp claim from all the electric outboard manufacturers have two components to it. 1: electric motors have all it's torque at very low revs, so they feel much more powerful when in fact they are not. 2: based on that fact they all use a very large dose of marketing bullshit. I am lucky to have a diesel car and a gasoline motorcycle i also have an electric bike, electric scooter, electric motorcycle, electric car, electric hair cutter electric toothbrush, about a gazillion battery power tools, none of them have issues and none of them are known for having issues regularly. So could you explain why you have the filling electric outboards will be different?
@reversingentropy Let's deal with facts. You can't say it feels like 3hp. THE FACTS are the calculation from 1kw to HP is 1.34 hp the drive motor is just a normal brushless electric motor.
@@andrewstone1868 Yes i can. I had both the electric has much more torque it gains speed faster and does not hesitate while gaining speed, but when you are at high rpm it lacks the power to go faster. An electric car does exactly the same thing it has huge power off the line is feels like the car has much more power then it actually has. And at speed the power just ends. I have no horse in the race, i don't care who buys these outboards... But I'm wondering, why do you hate them so much?
The electro motors are NOT inefficient. Electro-Motors are most efficient of all motor types. The reason why spending 2x more power is not resulting in 2x more speed is just physics!

I got a fishing boat (4m fibreglass reinforced plastic) got a small brushless motor (Zebco Rhino BLX 70) which is on a 12V AGM battery (kind of like car battery) - THIS is a heavy battery...weighs about 20kg ..for maybe 2-3 hours of driving at 3,3kts.
The Spirit got the "light weight"-Version of a battery, trust me 😅
Its a pretty decent concept for short ranges on a sail boat, short trips on a lake...for landing on shore with a dinghy you got the problem with the expensive battery.
Maybe they develope some locks for motor and battery...this would be a useful extension
Very well put... Lately we have been locking it all up with a chain. Cheers
3.5 hrs to recharge the 2 bars (6 miles) you did in your test? Or is the 3.5 hrs for a full charge from a "dead" battery? If I misunderstood, how long did it take to recharge from your 6 mile trip? Thank you!
Hi. It was two and a half hours to charge the 2 bars that we used on the trip.
However it seems the charging speed drops as it gets full. Like in electric cars, its 0 to 90 in two hours and then another two from 90 to 100... Seams like ita similar
The way charging works is that the fuller the battery is the slower it needs to go in order to charge safely without damaging the battery. That's why going from 10 to 80% on a phone or outboard or anything is super quick but 80 to 100% takes longer than 10 to 80 did.
The effect you are seeing with speed (velocity) versus power is about right. Drag follows "cubed law." If you need 200 watts, for example, to go 2 knots, you will need 2 X 2 X 2 (8 times) as much power to go 4 knots (assuming hull speed doesn't become a factor). The difference is: a gasoline outboard doesn't have a power meter, so you can't see that effect, but it's there also. It looks like you are doing a little better than the formula says you should, probably because the prop becomes more efficient at higher RPMs.
Sounds about right. Until you get into plaining then its much more efficient. I wish it would plain... Maybe next generation... Cheers
@@reversingentropy No generational shift will make it plane, you simply need a more powerful engine to do so and also a propeller made for higher speeds. The EProp Navy probably could but planing is better with gas engines as they work with higher rpm.
@@Black-March I wouldn't be so sure about that. I envision a higher density battery that will allow for a 5 to 8kw sustained for a few minutes without taking a huge hit. You only need high power to get from displacement to plaining. There are a few manufacturers that managed to do it but it's not in outboard form. Remember a few years ago your phone had physical keyboards. Tech moves fast.
@@reversingentropy You're talking about a significant overclock to the engine which would risk damaging it. And also it's not simply a matter of having a little more power for a moment or two, it's that electric engines are designed to work with low RPM high Torque, while regular outboards work with smaller props and higher RPM.
@@Black-March every thing can be redesigned. Drone Bldcs for example run at insane rpm and torque. The only limitation right now is battery density.
I just use a bike lock to secure my battery to the motor and dingy. It takes 30 seconds, not a problem.
Don't know if i would trust a bike lock. But yeah its better than carrying the battery around 😁
That's what we do. Simple, quick and easy. Probably not necessary as most boaters are well off enough that they don't need to steal. But the temptation to acquire an extra $1500 battery could be tempting... whether for backup or an emergency.
@@soundservices950 it's not the boaters you need to worrie about. Its mostly the locals... Every place has it's bad Apple's 🤷♂️
Just an upate after a 9 months waiting for my court date I have won got all my money back and goodbye E propulsion.
Care to elaborate? I don't know your story.
Why even try to compare it to a gas motor, shesh! You're not teach us anything we don't know
Never the less, Thanks for watching 😉
I have a guess here...that RIB is not going up on plane. So can it be considered a full displacement hull when using the electric motor? Optimal hull speed for a 9 foot boat in that case would be 4.02 Knots. That would explain why the sweet spot is 200/250 watts. Trying to push it past hull speed just sucks up more power with very little increase in speed. Again...just a guess.
Yep. That checks out.
Your video was helpful as I consider electric for our dingy. Sure want to get gas off the boat (and love the quiet) and am willing to go slower if that's what it takes. Thanks
Im very happy i could help. 😁 Cheers and good winds 💪
How much cost this
@@chandrahassuvarna2720 it costs around 2.4k cheers
@@reversingentropy is it's available in India
@@chandrahassuvarna2720 i have no association with e-propulsion, i do not know. Cheers.
Thanks for taking the time to make this video. I appreciate all your thoughts on the motor. I just started using my new motor and I’d like to know about cleaning and storage. When I take the motor off my dingy I notice that water drains out of a couple holes on the side of the motor, just in front of the propeller. After a few hours or a day of running around, do you rinse off the shaft/propeller unit, or do you go a few days or weeks before cleaning it? Have you done anything else to keep the saltwater from deteriorating the lower unit? Do you feel like the lower unit could just live on a storage bracket and be constantly exposed to salt spray? Thanks again.
Im not sure what is the correct procedure, but I'm sure its not what i do, because i have never cleaned or rinsed the motor 😂 when we are cruising it stays on the dinghy full time, and i raise the dinghy out of the water on the davits every time to prevent growth on the dinghy bottom and motor.
When we a not cruising i keep the motor in a locker. I have never cleaned it, but now that you mentioned it i think i will start to do it before storing it. Cheers
Thanks great video 🤙
No problem, cheers 😁
I found this very useful. Muchas Gracias!
You are very welcome. Cheers 👍
Thanks for this contribution. I learned things, enjoyed it. I'm thinking about getting one of these, so it was good to hear your thoughts after using it. Really like the way you put cool visuals in. Get one of them hairy microphone covers for the wind!
Thanks mate. Yeah sound sucks, so sorry. Cheers.
I have 3 need say no more
Am I understanding this correctly?
When on shore there is no means to lock the battery to the rest of the engine so one is forced to either lug 8kg around or risk it being stolen??
Yes, there is no built-in lock. However, you might be able to lock it using a chain and a padlock. Nevertheless, I would not feel comfortable leaving the battery on site even with a training padlock so I just take my battery with me.
@@reversingentropy - I find it staggering that no one in the design stage had the foresight to ask why the user would want to lug 8kg around when they reached their destination and provide no means of locking the battery in.
It makes me wonder what other practical considerations they were too shortsighted to see, UV damage maybe from months sitting on a pushpit?
Seems more like a product for recreational fishermen maybe rather than use on a tender. If so they’ve colossally misjudged their potential market.
I just use a bike lock on mine and it works quite well.
How much cost this
About 2.5k, cheers
Thank you. One suggestion: watch your videos and learn to be more concise. This video could have lasted 6-9 mins with the most relevant information.
Thanks for the suggestion, 😃 but why would i do that? What would in your opinion be gained by that approach? Sincere question. Cheers
Thx for this honest review.
You are very welcome. Cheers
Nice video
Thank you so much 😊
cool
Thanks. Cheers 😁
"Paied"??? WTF?
Looool i was tired. Fixed now, thanks so much. 🙏
@@reversingentropy All good. I just couldn't resist. 🙂
1kw is 1.34 hp Google it there NOT 3hp there poorly made try going against the current and you will turn around you won't make it .. I have one and they are good for ponds
You are incorrect. Just today i had to carry 60 meters of 10mm chain plus a 1.5kw windlass plus me 100kg against 4kts current. It was slow but steady. I will exchange ease of use no pull chord to start no gasoline no noise no smell no maintenance etc for slower performance any day. That being said I'm hopeful for more powerful versions to be the norm in the future.
@reversingentropy I'm NOT incorrect, explain the 3hp e propulsion claim .
You wait yours will break or go on fire
@@andrewstone1868 the 3hp claim from all the electric outboard manufacturers have two components to it.
1: electric motors have all it's torque at very low revs, so they feel much more powerful when in fact they are not.
2: based on that fact they all use a very large dose of marketing bullshit.
I am lucky to have a diesel car and a gasoline motorcycle i also have an electric bike, electric scooter, electric motorcycle, electric car, electric hair cutter electric toothbrush, about a gazillion battery power tools, none of them have issues and none of them are known for having issues regularly.
So could you explain why you have the filling electric outboards will be different?
@reversingentropy Let's deal with facts. You can't say it feels like 3hp.
THE FACTS are the calculation from 1kw to HP is 1.34 hp the drive motor is just a normal brushless electric motor.
@@andrewstone1868 Yes i can. I had both the electric has much more torque it gains speed faster and does not hesitate while gaining speed, but when you are at high rpm it lacks the power to go faster.
An electric car does exactly the same thing it has huge power off the line is feels like the car has much more power then it actually has. And at speed the power just ends.
I have no horse in the race, i don't care who buys these outboards... But I'm wondering, why do you hate them so much?
Very Nice Video...I just bought one haven't tried it yet...your info. will help alot Thank You !
Thank you so much. Hope you enjoy it. Cheers. 😁
