Follow the link above for all of the hardware needed for the RC Outboard!
Its impressive what people actually build with 3d printers and how people that are good can make pieces stand out
Just wanted to say that I see your questions about assembly instructions and I am working on a video, assembly instructions and a hardware kit so you all can start running the outboards!
In addition I am working on some boat hull models specifically designed for this outboard, stay tuned!
cant wait for the hardware so i can but put on a boat as all ready printed it
Looking forward to it!
Take my money!! that is the best looking and working motor yet!!! please keep me posted when you release the STL's You are truly doing awesome things here!!!!
Did he realise the stl files yet
I have no doubt in my mind that it could power a small boat with a person in it
now i need to see this
fishingboats actually sometimes use similar powered motors, +-700w electric motors are used to move the boat yet stay silent to not scare away the fish.
It definitely could! It should have more torque than a 3.5cc nitro outboard and I can say for certain that my thunder tiger.21 has enough to push me in my boat! I got caught in a strong wind in the middle of the lake and paddling with a single paddle was near impossible so I held on to the sides of the vs1 tunnel set the throttle to about 1/3 and leaned over the bow using it like a bow mount trolling motor it dragged me back with no trouble!
@@ted_van_loon 🔴 What Is Islam?
🔴 Islam is not just another religion.
🔵 It is the same message preached by Moses, Jesus and Abraham.
🔴 Islam literally means ‘submission to God’ and it teaches us to have a direct relationship with God.
🔵 It reminds us that since God created us, no one should be worshipped except God alone.
🔴 It also teaches that God is nothing like a human being or like anything that we can imagine.
🌍 The concept of God is summarized in the Quran as:
📖 { “Say, He is God, the One. God, the Absolute. He does not give birth, nor was He born, and there is nothing like Him.”} (Quran 112:1-4) 📚

🔵 Rather it’s going back to the original teachings of Jesus and obeying him.

@@needmoreboost6369 and if hogher torque is desired for higher efficiency(there is a ideal screw size for the speed and motor power, as well as the boat size/resistance.
one thing almost nobody thinks about is that with good gears you can make a highly efficient gear reduction box to translate part of the speed in torque, or torque in speed in the case of a very high torque motor(for example I had a electric motor with enough torque for a truck,(it actually was a electric truck motor a real one), but most often since people will use the cheaper smaller motors for rc, making a reduction gear box to turn speed into torque a good option).
then there is also the solex clutch(easily available for super cheap, widely produced) and also some even better(but have to typically make yourself) speciffic parts meant speciffically to increase motor efficiency, last years(last 30 years or so) those have hardly be seen or used anymore in mew products since right now often the solution is just throwing a more powerfull or bigger motor into something, but back in the past making small motors was really hard and motors also had very little power, back then such parts where used since using something like that allows you to do something that without such parts needs either a very finely high tech computer tuned clutch or a motor which is around 10 times bigger and stronger. for example the solex itself was super heavy, had lots of fliction at many parts, had quite little torque and still could go pretty fast and be rather efficient.
this is because it allows the motor to always spin around maximum efficiency for the givven load and speed.
in electric motors this gives even more benefits since electric motors are really sensitive to low speeds while super powerfull insanely high speed motors can be made super small and cheap these days, the main problem with small electric motors in heavy loads is often that they lack torque and instead of just not working properly under high torque their energy usage actually skyrockets while their poweroutput greatly drops, it is a effect quite similar to a short cirquit.
allowing a electric motor to run around it's peak efficiency point not only greatly increases power and torque but also greatly reduces powerusage
Add a bubble right over the prop like the f1 boats. Beautiful work man. Kudos
Can you elaborate on this? I’ve never seen this before! Got any links?
okay I've never seen an R/C outboard like that before, that's cool!
That is awesome! Very impressive performance
I see your comments about heat and how it might melt the outboard. Here's a video of extensive testing on my 3D printed monohull without any mechanical issues or overheating! I appreciate the feedback! ruclips.net/video/xqDSOy2boq0/видео.html

Coming late-to-the-party, but with a cool suggestion, put your camera gear in the aquarium, fix the outboard motor stand to the bottom of aquarium off to one side InFocus range of the camera, place the assembly in a round kiddie pool, this way the water flow will be consistent and you might even be able to demonstrate a rooster tail.
That's got some power😮 Sweet looking motor setup too
What a feeling when you printed it yourself.
Professor Vinster
Dang if I only had a 3d printed tunnel hull boat to attach this to. :)
I saw a design where the skeg had the hydro foil on it. so it overall protected the prop. helped plane at slower speeds too
That’s amazing to me wish I had that like 15 years ago😊
I will be starting this print very soon, thank you for providing the .stl
Where did you access the stl?
Print files here: www.ethoefler.com/outboard-build-page
Sweet! you can recreate the 70s merc tower of power! You should put one on a sidewinder! Retro style 2 stroke memories of growing up on the water in the 80s!
love that little 2 gallon tank lol. cool motor
maybe its a 5
Thing got some torque damn
my left ear loved this video!
Hahaha video editing is not my specialty🤣
Man that little thing moves some
Water. Sick
Extended use at high throttle level will most likely need additional cooling off the motor!
I'm running one with a max of 1,5kW. But I only use it to around 900W. It is not enclosed and It does need the water-cooling!
I think so too. I think that motor would be strong enough to power a canoe but you might want to increase the diameter of that prop if you can, and make it a three blade instead of a two blade try not to get to pitch to excessive.
This was in recommended. I subscribed! Great work!
Thank you!!
Awesome work!
Can’t wait to see that list of stl’s you’ve been holding on to.
Go check them out! www.ethoefler.com/3d-print-file-downloads
@@ethoefler thanks a lot for the files, great designs, but im more in gliders a the moment. I keep them for future
@@jeromedupont8994 I can’t access the files anymore. Do you have a copy of them?
Hey do you know were I could find gears for this? Thank you! This design is awsome!
Wow that's fast..., awesome work 👏
Mesmerizing!
That's pretty sweet, I hope it has the strength to hold together! That said, are you going to add liquid cooling of some sort for the motor? I imagine it's going to get melt-down hot under that cowling during real use on a boat. Maybe wrapping it with copper coils, or a heat sink clamp soldered to copper coils, attached to a pickup tube right behind the prop, or something similar?
Thanks
That is pretty bitchin! But one problem I do see with that is that it may get really hot. That may cause problems with the Filament depending on what kind it is. So you may have to try fitting a brushless cooling fan system. A while ago I had an idea to make something like that and I made a rendering of a hood that had that integrated into it.
Pretty cool. Me and my son are going to make a model of our charter fishing boat and use your engine design to power it. Great Job!
Awesome! Good luck with the build!
@@ethoefler Any chance you can model a cowel that looks like the suzuki df300? If not ok. But I am having trouble with printing of the cowl in the lower section about a 1\4" up from the base.
That’s awesome! I’ve been wanting to build a bass boat so bad.
Great Project. When you have the audio only on one channel apply on the audio track the effect called "fill left with right" or vice versa*this is for adobe/davinci.
you are the best man, thank you
Drill 2 holes in the small sides of the tank and attach a tube to make water flow relevant for the propeller
WOOOOOOOOOOOOOOOOOW !!!!
Test this in a donut shape container, so water flows better. But man, thats nice. I want one
amazing work
Waiting to see your F1 project finnished :)
Files out now on my patreon! patreon.com/EthanHoefler
Dude this is amazing!!! You deserve so many more subscribers
Thank you so much! I’m trying to put out high quality content for you guys!
That’s real nice thank you for sharing👍👍👍
I'd buy one, maybe two!
This is so cool
Wow that really is powerful, I would like to see some boat testing to see what it can really do.
That's awesome.
Wauuu very powerful, try those new sharrow propeller
Looks great! Excited to get working on it soon.
That thing is bad ass
Nice job! but it's going to need room in the cowl for a cooling jacket for the motor or it's toast!
STL files here: www.ethoefler.com/3d-print-file-downloads
i love you
Cool!
To sweet. Subbed
looks awesome! I'd buy one
will that motor survive under that cover with no cooling?
Need to put the color in a skinny tube down the wall n behind the prop so can add when giving throttle
How does the motor go heat wise? Have you thought about adding a cooling jacket and a prop wash pickup?
Please can you add subtitles for the little French ones, thank you
That is so cool
Only thing I would change is having the prop shaft extend into the bullet with another bearing. That said.....I'll take 2 please. Thanks! Contact me with information!
See how much thrust it puts out
you should divide your test volume with a return canal, as in wind tunel, so it would be like in real with water coming upfront.
Great stuff! Looking forward to the build list or parts kit would be great Also
You should build a custom fishing boat for it to go on
information if might be practical to use 'self-lubricating' gears in the differential; idk if heat build-up would be an issue. i am referring to the use of gears made of materials that differ in their hardness. the softer material yields, without deforming. this principle is the key to how a stirling engine can run just fine, with no lubrication. in this case, one gear could be SS.
What exact motor did you use? I didnt see it listed in the parts on the website. Sorry if I missed it.
Out now! :) ruclips.net/video/3wdQQVUUiJg/видео.html
I notice you didn't bother printing out a toroidal prop...
Is the prop 3D printed? I have delved exactly zero into the technology personally. If it is I wonder if simply scaling down one that goes with this motor from Mercury would work?
You said from the start that this was just what you had for a test prop. I do not know anything about 3D printing but I do know outboard powered boats. I noticed once you hit it you had way more power than prop.
If you think it could work Mercury made the SST series starting late 70s. Stainless steel five bladed. We would have put our girlfriends on the street for one. It had a really fast up on plane hole shot and didn't sacrifice top speed but it was expensive af. Might give you an edge if you plan to race it. Discontinued in the 80s but it worked just outrageously expensive.
This is nice work if you decide to make another different one I would love to see a Tower of Power the 1150. That's what we wanted the prop for. 👍👍
Nice 👍
Awesome.. How is the motor cooled though ? Isnt it fully enclosed in essentially an air sealed casing..
Check out this video to see how it’s doing! 3D Printed High Speed RC Outboard Boat Build
ruclips.net/video/xqDSOy2boq0/видео.html
Shit man that's better then my vita mix.
How does the motor not burn out with no air or water lines ?
Great job Ethan. Now take me for a ride on that thing
That's pretty neat!
I think so too!
That is excellent. Instead, using food coloring, use green laser or use strobe light .
Nice Work
How can i get hold of you as i am wanting to build a few boats with a outboard motor and uour the only motor i think looks real.
there should be a thrust bearing, of some sort, at the forward end of the thrust shaft.
I really want this mother not to be fast but be like real boat
3d print lower end with a port on the front the size of the smallest plastic treaded screw to cap the hole. Or just drill n tap so you can ad grease on the fly… is there a way to connect a scale to see how much force is generated
The best hpower
Awesome.........
I'd be interested in seeing this with a sharrow propeller
Wonder if the heat from the motor and the water that gets in the lower housing will cause issues.
You think this would be shrinkable to work at 1/24th?
Try the new design for the blade !!! Thay say way more efficient in water and air ...
since you have a 3d printer, i'd suggest checking out the LATEST designs for propellors. they seem to be a big improvement on the open-blade prop you're using...............
Very cool! Is heat not an issue for the motor? Could you design in a water cooling system, or possibly just incorporate an existing water cooling jacket?
Will it be sold? Send it abroad
Maybe I missed it on your site but do you have a hardware list?
Out now! :) ruclips.net/video/3wdQQVUUiJg/видео.html
What was the material used to print this motor? I have the prop just not sure on the lower gears and shafts thanks
PETG, I just shot all the footage for the assembly/build video. Parts list is coming in the next week or so. just editing it now/
Does it need the huge whale tail?
That thing is gonna overheat so fast
cool thing, i would applicate much more in the gear box. so the water cant go on the metal parts. One questiion.. can you put a golden ratio turbine on it? good luck dude
Hi i printed everything what bevel gears size did you use pls ?
maybe use helical cut gears instead of straight gears to reduce noise?
Good idea, the noise is part of the fun though!
Without cooling I'm pretty sure that will melt with real use. Have you measured temperature ?
I need the BOM! I have a old Nitro outboard id love to put this on!
Here it is! :) ruclips.net/video/3wdQQVUUiJg/видео.html
You should 3D print the newest boat propeller and test it I don’t know what is the name but you can look it up
Did the stl get taken down? I get a page error when I follow the link in the description. Would love to print it!
Thanks!
Sorry about that! I just updated the link! www.ethoefler.com/outboard-build-page
