Electric outboards! Confused? We take you through the options. 

Thanks, likewise; always inspiring being on your stand. Looking forward to seeing what the future holds!

Yup, no contest there! You need a big old Gas tank mate!

Thanks, we hope it was useful too! 👍

Cheers, hope to see some more in a couple of weeks!

Thanks! We have an innovations video coming out soon, there’s a really cool motor in that you may be interested in too 😉

Yeah, the KW HP debate… I think the industry is just trying to create a number that makes sense to average Joe. As far as I’m aware it’s based on performance not power. Electric provides more torque and we often find a more powerful prop on the electric motors, this provides performance similar to a 3hp. My experiences to day would suggest it’s not far off, for example the 1kw Torqeedo out performs a 2.5hp 4t suszuki.

agreed, but they are comparing to a gas motor which except for at one rpm are way over rated. simple machines like an air compressor you need twice the HP for gas verses electric for the same output.

Very true! But where to start with a new measuring system?

​@@lawrencekucharek3775Yes, but electric compressors also have a surge amperage rating quite often 2-4 times the rating of the motor. Just like a petrol engine, electric is not designed to run at very low rpm, they still have an efficiency range.

Engineering should have taught you that 1hp is 735 watts. 745 watts is not the standard that is taught. This is why the standard rating for all engines and power is KW.

Hey Richard, I can see your thoughts there. Our friends over at distant shores are building something similar. As for us, stay tuned to see what we build 👍

Thanks Peter! We’re working on it👍

Great work, I can easily see how this works for you. For us the Temo was the winner, battery size is smaller but on a small boat storage is everything. Most sailors only go short distances so a large battery isn't paramount, storage is always an issue and the Temo 1000 is the clear winner in that department.

Dear Dot Connector, there was a little mistake in the figures. The TEMO·1000 will have a 950Wh battery and not 740Wh. Indeed it will be smaller compared to the other, but as you mention, we corrected some other points, and the weight and the space requirement was an other point. At full power (around 4kts) TEMO·1000 will have 1 hour autonomy ! Don't hesitate if you have any question.

Why would you want battery? Hybrid would be a smarter option, and if we don't buy other limited Things just to spend extra money. We could force company's to make a smarter, better solution, battery alone isn't it. Were not ready yet.....

I have a 43 ft. holiday sailor, with a Chrysler 8 cyl. and a 21 ft. boat for ocean fishing twin 300 hp. and I feel underpowered at times. I go 150 to 200 miles out some times. a hybrid I could live with, a battery would leave me wet and DIW. @@SailHub

@@richardkrueger9097 -I have tinnitus in my ear, so I can't handle loud noise. I tend to always buy electric for reduced noise. I still use ear protection, but it's then bearable for me. I know gas is probably better. I've come to appreciate not having to maintain electric machines.

The shaft lengths offering is a winner!

Hi, thanks for your comment! Both myself (Chris) and Jenni are have spent our time in the marine industry as a boatbuilder/fabricator and sports engineer. The amount of boats, engines and rigs we have worked is pretty high and we are dedicated to supporting the industry as it moves forward with new designs. The heart of Sail Hub is Marine R&D, let’s just say there’s a huge push for sustainability with us too - the next year we have something epic starting, too soon to let the cat out of the bag just yet though.. I hope you join us for the journey! ✌️

💯👍

Hi, basically any electric motor span in reverse will create power… due to that they all suggest hydro generation is possible. The problem is that they are terribly inefficient and they don’t give any numbers to go from. Stay tuned though as things are changing! We have been informed of a press release in 2 weeks that could be interesting! On a side note, check out Sea Drive’s Azimuth pod drive. If sound 180° to get better water flow and generate more power. Maybe replicating this 180° shift would be worth while, although to get the most out of it you would need to reverse the pitch of the prop - like the Gori that sea drive uses.

Tell us more about the “scout”!

I believe they are out there, but the range is poor unless you have a lot of batteries and then the weight issue comes back… stay tuned, if we get a chance to review some we will be!

Sadly they are not really for your intended use, it looks like you made the right decision to me!

Good lord! We had a Suzuki 2.5 and used over a litre in a month! I guess it depends on where you are and the conditions!

There’s quite a lot of Marina charging happening in Scandinavia right now but like you say….. When it becomes more mainstream what’s the mark up on a kWh and is it really a viable alternative for the sea anyway? Only time will tell. For us, it’s about the people pushing the limits and trying, that’s not a place for industry to be involved, there’s people livelihood at risk there, but in the leisure sector, there’s plenty of ideas and people trying it out, this is always interesting even if it doesn’t work out!

To be fair electric motors are doing quite well for range, the Aquamot has the largest range that we are aware of. (For an integrated battery style that is) The problem is that when you use more throttle the range diminishes super quickly. Which is no good with minimal charging systems and wind over tide etc - still you can plug them into your alternator charging easily and the charge curve is very linear and super quick so really it’s not a problem for those who move around a lot. If you hang at anchor a lot though…. You may need a solar farm on a dinghy 😂

🤣low battery syndrome.. We ensured that for the first time here ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-txFtoN81vnw.html

Hey Kelly, I think you have a common belief there. Things are getting better and there are some good motors out there for you - we need to do a video aimed at your style of boat. We’ve been invited to a new product release from a well known brand which sounds promising and I really hope the price drops soon. I know that they have some really interesting data and how long it takes to “break even” it’s actually very surprising. Still, they won’t tell me what they have until November! Thanks for sharing your thoughts too - really important for manufacturers to see what they need to do next, we will pass it on! 👍⛵️

Sadly… your right.

Hi! We did actually, there was one of their smaller outboards on the EcoFlow stand. Unfortunately they had no-one to tell us about it and we were not able to film it. Maybe this year will be different!

Hi Alex, will take that on board for our next videos - stay tuned for a bunch of outboard reviews later this year, I will put the run times in for you . - Chris 👍

Always an option! Currently our is a 15hp mariner…

Mechanical and electrical Kw are the same, it’s a measuring of power. The confusion is that electric has greater torque per Kw this means it can drive a larger prop and create more thrust from the same power. Hope this helps 👍

Hi Sven, I forgot to answer the range question, basically range is not something I thought about, mainly because there’s mo standard for testing that I’m aware of. I’m not sure I can be sure the figures are comparable, one manufacturer’s testing is different to the next. Then there the sea state and boat size/weight, it all plays a part.

A piece of equipment

Milked out for decades! 👊🏼

what are you talking about? modern 4 strokes hell even 2 strokes from 30 years ago are quite and smooth. the benefits of low weight, high power, ease of refueling and low cost (especially used) are why they are still so popular. these little toys are fine for tiny dingies that cannot plane off, but when you want range and speed plus reliability go with a gas motor.

For sure, gas is awesome for speed. We have a 2t 15hp for just that. 4 t is not for me, too much weight and I’ve fixed so many over the years that have gone for a swim that I really don’t want one myself. If I had a choice though I would use a 6hp equivalent electric to get me by most of the time. Saving my back for when I need to lift the 15 on for those days when you NEED that extra umph.. which really doesn’t seem to be that often anymore. All being said, the only outboard I actually own is the 2t 15hp I currently can’t justify the cost of a lithium motor.

Hi Pierre, Thanks for your comment, this video was all about the average sized motors. Believe me, there are plenty with a 10-15hp equivalent out there. Hopefully we will get some on the channel soon for you! 👍

@@SailHub 9.9- 15hp IS an anveraged sized motor. Electric OB's all seem to be equivalent to 3-6hp If you have access to ones that have 9.9-15hp equivalent, that would be fantasc to see! With my experience being able to get yourself unstuck is REALLY important.

Sure, I can appreciate your need for that power. Fingers crossed we can get some on test.. Check out new motors from rad, propel, Edyn and of course the new ePropulsion navy models. Of course there a bunch more but all bigger motors need more battery power so they are external- like a petrol tank really.

I think he needs to learn how to read charts.

?

What in earth does that mean? A fascination with canoes? 🤔😜

@@SailHubI'm guessing it is just a French pronunciation , it is very cute

@sidon1979 Ok, I’m lost here! Im going to have to watch it through now! Canooowie!

Keen eye for detail 😉

Oh man, what a horror story. There appears to be some well made ones out there these days, we’re looking forward to testing some next season.

@@SailHub It was a real shame as the concept is great and it was nice not to have petrol on board.

@ClivehWright yeah, They we’re the first and things have moved on.

@@ClivehWright nice not to have petrol... until you are stranded and would give free handjobs for a few litres and a proper gas motor with some real l power:)

Nice, stoked you found a pace that suits you!

Now we’re talking! I think that’s a good question, I’m not sure of the torque qualities of a toriodal prop, I guess we will find out, something we will be watching closely!another thing on props though - Propel have a monster in their new outboards, still traditional in shape but a different shape due to their motors huge torque output.

😂

FCOL what part of the world?!

Interesting thoughts there, I can see the frustration’s and agree with you! Aside from the 1l part, when trying to achieve good lph with an engine your not at full throttle and electric motors are exceptionally economical at low rpm so the range is usually very good when used efficiently. The charging is interesting, with a hydro generator things begin to work and make sense (at a massive cost). Although with many motors becoming their own Hydrogenerator the tech is catching up to our requirements. The problem is that we need to support the right companies in order to progress in the right directions… and this much needed support is not cheap.

@@SailHub ah, yes… full throttle… Part of having a dinghy is the fun… A 2 stroke 15hp is most fun at full throttle! 😁 A more important aspect is that most good anchorages (particularly free ones) are often 1km or more from where you can land a dinghy (beach landings Need a lot of power, so we won’t go there!) whilst I have seen people using electric outboards in those situations, I am usually already in the bar ordering my second drink by the time they get ashore! On the aspect of hydro generation, I love the concept, but it is like having solar panels as sails… 99.9% of your time on a boat you are not actually moving, and when you are you don’t need the power (and you can’t store enough to make up the difference!) We need better storage technology. There is a problem there though as well… anything with really good energy density is otherwise known as a bomb ☹️ I’m sounding very negative, I love sailing and cruising. I come from an engineering and computer science background, so I’ll think of something eventually… maybe alcohol fuel cells and super capacitors would do it (make your own fuel!) What we really need is proper nuclear fusion and superconducting batteries, but that is science fiction at he moment (and not in the interests of oil companies or corrupt governments!)

@droneonamission again, som super relevant points, of course it depends on where you are etc etc… but like you say, progress is hindered by corruption, the answered will evolve as we must evolve for the good of our planet. The corruption still remains and we need to use our own heads to figure out what the truths are along the way!

Now that’s a thought!

I sort of agree with you to an extent. However, I don’t see Torqeedo or ePropulsion going anywhere anytime soon. I also would love a great little 3hp electric motor to use with a 12v battery, but most of the traditional offerings on the market don’t offer the same performance, weight, and ease of use that some these little Torqeedo and ePropulsion products. I think the 12v aspect is a big limiting factor, but I’m not an electrical engineer. Also, the lure of proprietary batteries is probably a huge temptation for these companies but I think eventually someone like Minnkota or even one of these other companies will give us what we want.

@@jordantatum4339 Not sure what the voltage of these are but they are likely 12 24 or 36. In that case all you have to do is hook up the 2 or 3 12 v battery's in series to get your higher voltages. Just like the trolling motors u see on fishing boats. But they really need an alternate power source available before I'd by one.

​​​@@curtisp5696 no you can't use any other power source as they build in part of the speed control into the battery, and they are 30v, its been tried.

That's why I'm staying with the trolling motor for now. Proprietary battery formats are a blight in too many places.

Yup, that’s a pigs ear…. Not sure what happens there. Range is tricky to put a number on too… it’s all down to manufacturers which generally need to be taken with more salt than the average Mediterranean diet! At some point we will do the rounds again and put our mistakes right- thanks for pointing them out! 👍

I’d rather not! That’s frightening! 😂 Your right though -it’s a serious concern!

ICE cars catch on fire far more often than EV's.

It’s going to be interesting times, that’s for sure.

Gooood shout👍⛵️🌎

✨Easy To See Also 💚🪂⚡️

I think the Earth does not even know WE are here; the climate HYSTERIA is killing our lives already,not our OIL ENGINES, wild fires raging on for months on end, in HUGE areas as we see on TV, that may create some permanent change on the air, not sure, but no one talks about that, there is no money to be made there, the climate HYSTERIA,that yes,that is a huge money maker with all kinds of TAXES and legal impositions on engine building that makes them SO complicated that the cost is often MORE than the cost of the motor itself and gets them scrapped to the junkyards in numbers never seen before!!! of course the HYSTERIA has passed the point of non-return now,but THAT is the way society works, until most are disgraced; the rich keep raging on sacrificing the others,the desire to DIE RICH is,after the divine CANCERS, the greatest evil there is.

No one will disagree if you give them your money so that they too can make these environment first choices. However, money is a very real consideration for most people do costs need to come down.

@@craybro not making a great deal of sense there. - maybe a typo?

Wow, just got this translated - strong thoughts, why do you think this? Is it not a case of where you are and what your doing - such likes as it’s a bit of a waste to have a 15hp outboard on your dinghy in somewhere like Greece?

Cheers Richard, we will do our best!

Fair point, check out a company called propel - not sure what happens with them though, seem to have gone awal. They have an extremely high torque radial flux motor on a reduction gear box leg drive. -no water ingress and you can actually use all of the torque the electric motor creates due to its reduction gearbox.

Yeah, it’s a funny thing, it’s just horses for courses I guess. I know that ePropulsion have fishermen raving about electric in South Africa! But hey must not be going go far and must be coming home every day, I also think the price of fuel is very high there, possibly a bit of a tainted perspective.

This is very true…. But what If your not able to make your own and you want reliability, portability, a warranty and a plug and play system? At the end of the day electric motors are nothing new but it’s only just becoming mainstream and we must think about what matters in this area. Batteries are of course all was a challenge too… That is another topic but it is closely related to storage, which many outboard manufacturers are trying to incorporate into their designs.

I can certainly see your point, although I do believe there is a place for these motors. For me, I would suggest thy it is for Med cruisers or weekend warriors at present.

😂 stay tuned and we will see 😉

Hi Brian, thanks for your comment. We could not agree more! Sustainability is at the heart of our channel and we will be covering it a lot in the future. Based on belief from the researchers that we have spoken with, at present we would not recommend replacing an existing motor for an electric one. However, it is also hard to recommend buying a petrol motor to someone who is buying a new motor. We are currently questioning scientists on this exact point and we hope we can help others make the right decisions for our planet. Thanks again for a raising a really valid point. 👍

It is good for the environment

@@ianrobertson1952 Hi Ian, these days we find it’s hard to tell what is good for the environment, we are informed from all sorts of directions which often seem biased. Sail hub are trying to source some research to find out what is actually best - mining lithium, or burning fossil? What are your thoughts?

@@SailHub The Lithium that is being used in the battery's will all be re used as the battery's wear out. At the moment they are lasting longer than they thought they would. Just the noise pollution from petrol and the oil in the water is enough reason to change. The whole battery thing is evolving so quickly Tesla has dropped the use of cobalt and and is moving to iron phosphate battery's in most of it's new cars

@@ianrobertson1952 it’s a really interesting topic at the moment, we are looking forward to this summer where we are spending time with some of the marine key players. There’s a few ways things are moving and we intend to find out who’s doing what and why!

Cheers, I’m completely aware of that. Still said the wrong thing mind 😂👍
