Beautiful, quiet and fast, friendly environment! No matter how many hp equivalent, the important thing is that it works well. Congrats

Those Manta 2 motors put out 10 horsepower each motor so he's got an equivalent of 20 horsepower there had he used the water cooled motors instead of the motors he's using which they do make a water cooled motor it has coil copper around the housing he could have used the lower units cooling water pump system that's in all outboard motors to pump water out of the lake around the motors and it would have kept them cool he probably would have doubled his time on the battery and remember the more batteries you got the longer time you get and if you can get some solar power panels on the roof of a boat just put four poles on the boat and throw some solar panels up there to recharge your batteries at some point you're going to run out of juice but you can have a fun day out on the lake before you ran out of juice and you don't have to worry about your motors overheating if you've got cool water from the lake pumping around your motors he's got the principal right he just needs to add a cooling system and a recharging system so he can get more time on the lake

WOW, very impressive speed. Great job, looks so neat, too.

SERIOUSLY cool project guys, brilliant stuff

This is awesome!! They need to push these into mass production.

That's great guys! Looks like it moves right along. The earth appreciates it.

awesome.....I love that you guys made a motor that can still haul ass, but doesn't put all the crap into the water. Every lake that i go to that allows gas operated outboards has an oil slick on the top of the water ( just from all the boats running their exhaust into the water )

I must say that's rather impressive.

Well done! Runs very Nice!

that is awesome great engineering guys. y'all nailed it

I agree that performance is on par with a 25hp motor on that boat. Very cool!

Dam very impressed .. I like your set up !!

2.29 , it is like a plane is approaching, nice vid and nice motor.

Absolutely brilliant.

Good one guys.................Great effort !!!

Finally. Somebody that reported real measurements. Keep at it guys. Use gel cells as they can handle direct sunlight. Build a permanent housing for them and use anderson connectors that can be handed pierside to an external charger.

great work

A++ for the motor

Wow thats some serious power !

Great bit of innovation

awesome motor what a power!

thats pretty awesome, have you improved on the design at all since this video?

Very nice guys... Excellent.

I've clocked our 14 foot aluminum boat at 30mph (50km/h - GPS actually). That has a 25 horsepower motor. The difference between 22mph and 30mph is huge. You probably have more like 18hp, maybe a little more.

I'm impressed!

Great Job!!

how about adding a top cooling air intake snorkel and discharge to aid in motor cooling?

great job!

Amazing great work

Nice job

that was sick bro... you should just put a vent chimney on the motor case make it 8 inches or so high so the heat can escape and you could put a fan in the chimney as well. use pvc for the chimney...

seems super quiet been wanting to get a electric motor for my jon boat this just makes me want to het one more ya'll keep on building boys!

Did one etec get hotter than the other? Did you test both of them to see if one was working harder than the other? awesome build!

This is so cool! :)

Nice, good job. I saw one where they took and outboard bottom end, and bolted on one of those big ones like from a car 150Kw motors. it was FAST.

thumbs up ~ very cool dc motor project ~ how many watts per motor ~ or total power is consumed @ full throttle? just curious...I think its fantastic ~ also, does it get better mileage just doing hull speed? vs plane?

super awesome! id buy one.

I love that you used plexiglass to be able to see what you're doing, and the video shows why temperature is such a key factor for electric boating. The battery choice was a good one - much better than most electric boat efforts. Great to see. Is this video taken in Sausalito? To see a fast electric boat, see my videos...

i wonder how long the motor will last not being vented . seems like you did what 4 trolling motors can do better but hell i dk what to think but its kinda cool

That's awesome! That would be great for trolling! I want one!

Nice! What do you use for speed control, resistive or PWM? For the naysayers, there are lakes were gas engines are not permitted. This would be ideal for those situations.

Run a flat copper bladder / Pipe beside the fields make one end in the water like a small funneled P/Up motion pipe for cool water let it run by the motors run way cooler . Good idea lotta force .

"can't see the temperature of the motor because of the fog built up inside..." "...taking a look at the motor casing, looks like it's staying dry, no moisture inside" lol

Say - ‘condensation’... now look it up... haha

That's pretty cool! How long do you get before the batteries are out? It would be neat to be able to swap my 15 HP 2-stroke for an electric outboard, but if they're anything like electric cars, run time must be a problem? My minivan can go from San Jose to San Diego without refuelling so long as I keep my speed down; no electric car comes anywhere near that range.

wow that's awesome ! wish I could buy one for myself! that's supposed to equal 25 hp? wow.

nice power

great built, how much kg does the whole engine have

It needs air flow

yep !!

great job. how much to build?

Shorter, heavier cables needed. Performance looks on par with a 10 hp. Very cool project. As with most of these types of things, battery life is the weak link.

Very Good!

thumbs up for ODI BMX grips!

A solar vent on top of the box might exhaust the warm fog and cool the motors. I had a vent for my enclosed battery/controller.

Good speed, and better performance then some others I've seen on youtube that are manufactured for money basically a 9.9 for top speed.

condensation is forming inside the case. You should have built splits to circulate air inside the Motor COVER

Great! I subscribed to your channel! I'm in shipbuilding!!!!

It's the Binford Model 7500 trolling motor !!

I am impressed. The motor must get the air cooled somehow. What motor and size do you use? Thanks!

soo pretty much like a big trolling motor! BUT BETTER!!

if the prop stops suddenly, will it strip the teeth on the drive belts, when you star big power tools if the tool is locked down or stuck and you turn on the motor,,,,,it eats the drive belt.

How are the motors getting any cooling? Where is the airflow or are the water cooled? Is that a sealed case? How is the motor controller getting any cooling at all? No wonder you are getting increased temp readings

how does the two motors work together to make it work

So how did you do this to where your three phase wires wouldn't get hot because I did this in my three phase wires smoked up at the motor

TIGHT WORK

At this writing this video is 7 years old ...Marine Engine Designers have been trying to crack the code of electric powered outboards almost as long as there has been electricity. Heat dissipation and battery technology have always been and remain the two barriers that cannot be over come. So it remains to this day...

I would totally buy this if it were similarly priced to a 25hp

How high is the torqe? If it is high enough you could use a larger prop with a greater pitch, ala the prop used by the Torqeedo motor.

@rowen211 4 stroke or 2 stoke ive got a 5hp 4 stroke as an auxiliry for my rib

You are aware that the Manta 11motors , they have one that has water jackets on it. basically it's coiled copper around the motor . and you've already got a water pump in the lower unit of your old motor ... so you can pump water around your motors to keep them cool right out of the lake....

Wow really loud. Why didn’t you use 24 volt DC motors. Great idea.

Nice Trolling motor. I'll still stick with my Yamaha 250 Saltwater Series though.

Amazing you should try an air scoop on top of the box no water will seep in an air scoop on top and for the batteries a thicker gage wire would work just fine that way the cable doesn't get hot love the idea i want one hahaha

Nice.. how many watts of a motor

Nice.

"I got stranded ran out of juice" "ok I'll bring you some gas" "eeehhhmmm........."

sealed in a box no ventilation what about salt water?? looks neat good job!!!

Nice, electric motor outboard... never used gasolines and oil...only batteries fuel... 1k to 100k RPM at 40 to how many kilometers per hour travel before to drain the battery...?

On a hot day the clear cover is going to act like a Glasshouse.

This is interesting, but will only work for short pleasure cruises. Where I live, it takes me 30-40 minutes of driving at 15 knots to get to the open sea, and if I'm going fishing I need another 20-60 minutes of driving to get to a good fishing ground. Then I need to get back home and I want to have at least one to two hours of driving in reserve. Once a battery powered engine can do that, I'd be interested in buying one.

Add a sail.

where do u get that boat i looked on all the websites ik

Very cool idea, but a 25 HP 2 stroke motor would push that aluminum a lot faster then 22 MPH. I have a 25 HP Johnson on a 15 Foot fiberglass runabout that's pretty heavy for its size. I get around 22-24 MPH out of her never mind the motor on a light aluminum boat. Awesome idea tho I would like to see the final product in a video!

if you could incorporate a alternator in there with motors and have it tied together so every time you run motor it would charge batterys back up...just a thought

+Vernon Yow A not very sound thought, I'm afraid - you'd use energy from the batteries to recharge the batteries themselves, with losses, that'd just eat up more energy.

I like internal combustion better as well, as long as they make it clean - the electric power comes from combustion anyway, if you think about it - the power plant. Europe has been running diesels for years as the primary source of combustion, and they beat gas hybrids for economy and efficiency. Plus, Canada has pollution from mining the nickel for hybrid batteries. they can make biodiesel from almost anything organic with only oxygen and water as a waste product(even from sewage).

god job

Esta bonito pero si le hubiesen puesto un dinamo - alternador internamente para recargar la batería le darían mas durabilidad a la misma... piénsenlo..

It needs ventilation and cooling!! Put a vent fan on it, there's no way for the heat to dissipate. but honestly that seems like an awesome idea!

Tyler Scott it would be better to liquid cool it. electric rc boats are liquid cooled pretty easily.

thats awesome

How is it cooled?

Great build by the way... Just a couple questions. Did you experiment with different size and pitch props? Second would be . Would shorter battery leads draw less resistance and thus get more out of your batteries. I know the weight distribution would be changed but the driver could sit forward a bit with a longer handle? Just a thought. Hey good luck on your cool build.

Exactly. Long cables are fine, just need to be larger diameter to feed that many volts/amps.

And the pitch of the prop, should been a no brainer, almost unlimited tourqe. Should = large diameter and maybe even a 24pitch.

How long will it run on a charge?

Very cool, if you had that motor on a smaller boat, 14' or even a 12' she would fly!

wow im impressed!!! as for the engine heating up why dont yall run water from the lower unit up to cool the engine, just like in a gas outboard. Just a thought...cause i know that eletric RC boats use water to cool their engines also.

what eTec motors are these? brush/brushless?

This is totally awesome! my buddy and I have a Mantra motor sitting in the garage and want to create the same electric outboard, however, I'm a contractor and he's a seamstress neither of us know much about engineering, we're stuck... We have an old 2 stroke outboard to use but we're not sure how everything goes together on the electrical side i.e. speed controller, voltage regulator, batteries, heat tolerances etc. If you have any drawing and would like to share we would love your help.

Whatever you do don't make the same mistake as this guy made rap some quarter inch copper tubing around your motor each Manta 2 motors have 10 horsepower so he's actually got 20 horsepower there but 10 horsepower is plenty if you're going to put it on a Jon boat and if you wrap quarter inch copper tubing around your motor and hook that one inch of the tubing to your water pump coming out of the lower unit when you pull your motor apart make sure you hook a rubber tubing onto your water pump so it can pump the water out of the lake and around your motor while you're traveling it will keep the motor cool rather than let it overheat like they're doing especially they've got it in an enclosed box with no air holes it needs to be cool or it will burn up those motors are very expensive running anywhere from 5 to 800 bucks a motor no sense in burning it up right off the bat if you put copper tubing around it and pump water around it it will keep cool and there you have it an all-day trip the motor will perform a lot better if it's not overheating and it will last longer and then get yourself some poles and put them on your boat on your jon boat and put a little roof on it and throw some solar panels up there the solar panels will help recharge your batteries while you're burning them down and you will get twice as long on the lake you can actually get enough solar panels so that you can run the motor basically all day long especially if you stop and do some fishing in the truck the batteries are charging up from the sun while you're fishing or while you're having a picnic somewhere or drinking a few beers yesterday LOL

what is the tork for the mortors

How long the battery lasts????

What motor is the foot off of ?

how did you make the speed controller?

GREAT GREAT GREAT GREAT. I coach rowing. My launch is a catamaran. I do not go any faster than 20KM/hour. The launch I have is a stillwater weighs about 250 pounds. I currently use a 15HP motor that is PLENTY of power. I can't wait until I don't have to drag gas down to the launch anymore. I coach three hour stints every second day or so. What are my current options? Thank you and great job. Keep innovating let's get rid of foreign oil!

Richardson bay??

How many amps was it drawing?
