This little brushless DC motor is 22.5 kW
That's equivalent to 30.5 horsepower
That's crazy!

You know, there's a lot of perks to being a YouTuber
sometimes I just get to build toys, for myself
The issue is:
Sometimes those toys don't really fit the whole categories of
comics, movies or videogames which, uh
Make It Real is based off of
But usually when if I think hard enough, there's always a way
that I can twist it or bend it to make it fit a Make It Real episode
So on this episode of Make It Real, I'm going to be making:
Silver Surfer's surfboard!
Well, It's not gonna fly but it's gonna be like-
Well yeah, but... Shut up I don't need you
Can you bring the camera over here?
So how exactly are we going to build Silver Surfer's surfboard?
Well the very first jet-propelled surboard
was made back in 1965 and was called the Jetboard
It was actually designed by an ex-Boeing engineer
and it was actually powered by a 6 horsepower gasoline engine inside the surfboard coupled to a jet pump
It was quite impressive at the time
but technology has come a long way since 1965
which means we have stuff like this
Now, a gasoline surfboard is pretty cool
but electric is cooler
And, thanks to today's technology we have way more power
In fact, this little brushless DC mottor is 22.5 kW
that's equivalent to 30.5 horsepower
Have you seen a 30 horsepower boat engine?
It's like- it's like this big:
In fact, this motorcycle, this 320cc motorcycle which can do 180km/h
only has a 35 horsepower engine!
That means this motor is almost equivalent to this motorcycle
That's crazy!
But how does it all work together?
Well, the batteries power a liquid-cooled speed controller which controls the motor
The motor is then coupled to this jet impeller
which produces around 500N of force
Then it's controlled using this waterproof remote
which communicates with this wireless receiver
It's pretty simple
We got all these parts from MHZWatercraft.com
a world leader in DIY electric surfboards
Let's test it out!
Alright, we're ready to go
Now when I pull this trigger...
The motor spins

So everything seems to work
let's test it out with some water!
So this isn't a very scientific test
but basically, we're gonna shoot some water into the inlet
and make sure it comes out the outlet when I spin up the motor
Dave?
Yeah! Totally works
This test proved nothing
But hey, that's how you make a video, back to this spot...
All the components seem to work which means all we need now is a surfboard
Which luckily-
I already have!
Fine!
So, y'think you can wrap this?
- Never done anything like that before but I can certainly try
Alright, awesome!
- I was expecting...
About 2 and a half-3 hours
The other side I don't have to do as much as this patching
I just gotta do the rear and then I can just put a sheet on
This is time-consuming right here, tucking it all in
But yeah it's going better than I expected
For all your vinyl wrapping need check out Twin City Graphics
big thanks for doing such an amazing job on our Silver Surfer Surfboard
There, you happy? It's silver now
Look at that...
Now we just have to put it all together
Okay, step one, I'm gonna install the power train into the board
Alright so we got the motor installed now
which means I just need to add something to hang on to
so we're gonna add an anchor to the front end
which is gonna be tricky cause I actually have to...
Reach my arm in-
we'll see how this is gonna go
Roughly here
- Is your arm gonna fit, do you need a skinnier arm?
Just don't drop it
Alright, well you're there
backup
Oh - Now we spin it
Oh? Yeah!
We need to fill that up with silicone
without accidentally pushing it back in
So I'm thinking put a safety net on while doing this
Since this surfboard is gonna have so much power
it would be a shame not to try pulling things
So we're actually gonna put two stainless steel U-bolts
on the back of the board
so we can tow some things behind me
Alright so the board is almost done, all we need are the batteries
Now, like I said this is a 22.5 kW motor
which means it draws a ton of power
Luckily we have these awesome tattoo batteries from Grepow
Grepow is a company that makes batteries for pretty much everything
from electric cars to consumer electronics
And these are some awesome li-pos
22000 mAh at 44.4 volts
They're actually the same batteries that we used in our half-scale Cybertruck build
Plus, they'll make the surfboard last for quite a while
So let's see how we're gonna install these
Battery number one...!
Battery number two...
Slide this guy over here...
Got our connection wire
Make sure everything is snug
Perfect!
Alright so we got everything plugged in
which means it's time to test it again
So first, we turn on the remote
Let's see if she works!
Sweet!
Everything seems to work, which means we just need to install this cover
and I'll be good to go surfing
You'll see when I'm on the water
- Darryl!
- This isn't gonna work James
I thought you said you didn't need me at the beginning of this video
- Shut up!
- Yeah baby!
Here we go!
That was awesome!
Oh the camera!
Aren't you supposed to be silver?
Alright that was freaking awesome
this has got to be some of the most fun I've had with a project in a long time
and that's saying something considering some of the projects that we've done in the past
This thing worked way better than I thought it would
but there's always room for upgrades
I think we're gonna add a second set of batteries
and a second set of wires to the motor too
cause they were getting a bit hot when I was going really far back and forth
