Two years later this motor is going strong ua-cam.com/users/postUgkxBZWgzfpS2Jj7JqIHyaSZjyVHNUgCKCBf Just uploaded a video of it after 2 years. We use it probably a dozen days each year on our small raft.-original review- We got this motor the other day and tested it out. I don't have anything to compare it to, but it seems good to me. It has all the features advertised - the motor housing is metal. We will see how it performs longer term and I will revise this review if needed. Some initial observations:- Good thrust, moves our boat around really well- It comes with a circuit breaker but no switch - so there's no way to kill the motor other than yanking the connection off the battery. I installed an inline switch.- The mount bracket is plastic and I worry it might break- There are a number of plastic parts that I worry about, but the most important ones are metal or some kind of composite
That motor will work pretty good I had a small 18cc motor with a trolling motor prop and it worked great till I blew the motor the flywheel was plastic and it got to hot and melted
Sometimes those small 2-stroke engines get a lot of oil coming out the exhaust and clogging it up, might want to check that and also maybe need to clean the carb
You might actually break your pistonrod, water is way too heavy for this engine. Even 3mm trimmer line could actually do that, more likely to happen with 2-stroke engines smaller than 30cc. Go for a cordless drill instead, fish happy, Greta happy😀
You know this is why I really watch your channel because you didn't think about the rotation of the weed eater versus the propeller and reality is you would like that thing to go back on the other way so it push like a traditional boat motor but it works so
Where there drive shaft connects to that sweet motor, it's probably gonna melt. I put a saw blade on my and it ran for about 30mins and was smoking like a greatfuldead concert. Still got them little saplings though.
I did this in the early 90s with an green weed eater and a 2 bladed replacement trolling motor prop. It made a lot of wind out of the water but in the water it had bad cavitation issues and then it just bog down and stop. I fixed it by trimming the blade length down little by little until it worked pretty well. The blade length was just under an inch when everything was said and done but it would push my canoe up the river with decent amount of speed
@@skipjames8437 I couldn't guess at a speed but I'd say it was about rowing speed.. if the prop went too far off the center line it made the canoe feel really tippy
You got the blades on backwards. But I like the fact that you didn't destroy the weed wacker to put a prop on it. You can take the top off and still use it as a weed wacker. Good Tinken
Fun! Keep up the good work! This may not apply here, but just in case it matters in the future, remember to be careful of the fumes. I met a guy who had heavy metal poisoning in his lungs from zinc (galvanized steel) welding. Stay safe. :) Can't wait for your next video!
Dude - if you mounted that at about a 45° angle inside a large leaf blower/vac extension tube/nozzle, you could evacuate all the accumulated stinky silt/crap/algae off the bottom of a water trough in about ten seconds.. Just make sure you aim the outlet AWAY from you LOL. For what its worth, I found a small plastic or resin boat propeller in the clearance aisle at Walmart for nine dollars.
Tried this with trolling motor propeller about 15 years ago. Didn't work. It would die every time you stuck it in the water. I trimmed the propeller off till I could get it to run in the water without going dead. After that it would barely move the boat.
A trolling motor prop has too much pitch. It's designed for more torque at a lower RPM, so it's quiet in the water. The angle drive on a weed eater is 1:1, and those small displacement 2 cycle engines don't have a lot of torque. He did the right thing, making a very shallow pitched blade, so it could turn fast enough to keep from slipping the centrifugal clutch. He just needed to pitch it to the right direction.
The pitch needs to remain shallow, since the angle drive is 1:1, and that small engine just doesn't have much torque. It was actually just about right, if he hadn't pitched it in reverse. Other than that, I think it would have worked reasonably well!
It needs reduction gears and small pitch. The 1:1 ratio prop ; engine Outboards have a reduction gearbox. Or use a tiny prop off a radio controlled boat that runs this HP engine.
He had the pitch shallow enough, that it actually would have worked reasonably well. The only trick would be to make sure the prop can spin fast enough, to avoid constant slipping of the centrifugal clutch.
Flip the prop around so it will be pushing rather than pulling, if you try and attach it to a boat as it is now, it will reverse. You could also try increasing the pitch of the prop in order to transfer more power into the water.
The prop pitch needs to remain shallow, because the angle drive is 1:1, so the prop needs to allow high RPM, to avoid slipping the centrifugal clutch. Those engines don't have much torque.
Dude EVERYONE else way over complicates this! Thank you for making this crazy simple. Only question I had is why you chose that size of prop. Just like, was there any math involved or did you wing just it?
That thing is like 6 or 7 feet long, your going to have to row out for a bit before you can use it, plus that thing will never start while in the water, but it will make a nice fan on hot days if you can stand the noise
It will start just fine: the centrifugal clutch won't load the engine, until the RPM is up. A stop ring can be used to adjust the transom depth of the propeller, it's just that the head will be up there a bit: he just needs to stand up, to pull the starting cord. He'll have to clamp a tiller handle on at a usable height.
U I tried it a few years ago with a home made two bladed prop, and a weed eater brand weed whacker. It was way under powered, and no torque. I was a failure. I think it was like a 18 cc engine.
from a weed choper, you made a water choper...propeller have much more pitch then that.. the basic small engine have 30 degree of pitch, and fast boat have 5 blade with 45 degree..that is why they are "moving"..
It needs a steeper blade angle. Froth is not the same as thrust and three blades spinning in the same direction at zero blade angles produces no thrust
I noticed that also.The question is, what's better for the angle drive as far as thrust goes?d(it's really easy to turn the whole thing around, and let it pull rather than push, depending on which way the foot is less susceptible to axial thrust from the propeller.
If he used on of the ones that has attachments he could make a mount using a bearing that fits the shaft and mount it to the back or front of a John boat
*DONT DO THIS* without any reduction the 2stroke engine will not be able to work even a small 3inch prop in the water because it cannot achieve the required high RPM. also those engine are AIR COOLED and will burn out if run a long time >1min at high torque low speed.
It looked like the prop had a shallow enough pitch, to allow enough RPM to avoid constant slippage of the centrifugal clutch.(it just looked like the prop was pitched the wrong way)You are right though, the angle drive is 1:1, which, with that tiny engine, doesn't give much torque.
Why go through all that trouble, just take a threaded rod attach a trolling motor prop with just a couple of lock nuts, run it through a 3/4 pvc pipe, attach to any cordless drill you want, way more powerful than that, will push a houseboat
I was thinking the same thing when seeing him start to weld, but on second thought the spin rate of that prop against a weaker motor probably makes it more efficient to have a less aggressive pitch. Could be wrong.
When the prop wears out you just tap it on the ground and new ones come out
oh..... I get it!
I feel bad for the people that don’t get this
BAHAHAHAHAHAHA
👍
That was clever.

you sir.............have made an excellent paint mixer and sprayer!
Dad:
Where is my 10mm socket??? Oh and have you seen the weed eater?
Sometimes those small 2-stroke engines get a lot of oil coming out the exhaust and clogging it up, might want to check that and also maybe need to clean the carb
Improper oil/petrol mix.

I made a floor polisher out of an electric weed whacker. It worked awesome
I thought about doing this a long time ago haha if i ever get a little boat i will have to try it
Awesome work!
Way back in the 60's, before the modern trolling motor, my Dad and his friend made them out of windshield wiper motors.

Under an inch and still moved water? Seriously crazy. Do you think you got it up to like 3-5 MPH? How fast is a rowing team?

Mate looking at you garden, you needed that weed whacker more
Take it out on the lake! Lets see how it works out!
Awesome vids dude keep them up
Yes indeed
Always thought about this. I would find a propeller .Too much work to make one.
My brother and his friend made one a while ago. Except my brother and his friend just took a prop from a boat and slapped it onto the a weed whaker
Very smart project, would you tell me how to make your boat too. Thanks.
lol great but did you put the pitch of the props in reverse........you had to turn it upside down? Great concept thanks for sharing.
Looks like good for stirring water
have you tried making cole slaw yet ? Great job.

love it!
YOU NEED TO PUT SOME PITCH ON THE PROP AND TRY IT ON A BOAT OR WATER CRAFT !! FUN IDEAR THOUGH !! GOOD LUCK!! 👍😉
The pitch needs to remain shallow, since the angle drive is 1:1, and that small engine just doesn't have much torque. It was actually just about right, if he hadn't pitched it in reverse. Other than that, I think it would have worked reasonably well!
It needs reduction gears and small pitch.
The 1:1 ratio prop ; engine
Outboards have a reduction gearbox.
Or use a tiny prop off a radio controlled boat that runs this HP engine.
So that's why when the engine cut off the spinning thing was loud

Really nice video!!
that's a pretty cool idea and everything but when do we get to see the GS 500 go kart actually move under its own power
Wanna see the next video I've tried this but didn't work out didn't have the perpellers bent correctly
Great videos
U
I tried it a few years ago with a home made two bladed prop, and a weed eater brand weed whacker. It was way under powered, and no torque. I was a failure. I think it was like a 18 cc engine.
You should make a go kart that floats on water with PVC pontoons and use this to power it
Shoulda kept it in weed wacker form and did some weed wacking around the crib
from a weed choper, you made a water choper...propeller have much more pitch then that.. the basic small engine have 30 degree of pitch, and fast boat have 5 blade with 45 degree..that is why they are "moving"..
Nice video, I want to make one of those so bad
Mason Canner nice👌
Mason Canner- it's been 7 month now did you make one yourself or not?
Your dad is gonna be pissed when he sees what you did to his weed whacker.
FireAndGasoline haha I have five weed whackers and I don't use a single one.
Well then he's probably already pissed.. lol. If you ever get ungrounded come up and ride with us.
hey FireAndGasoline
Hey planit MC!
glad to see you guys have done a bunch MOER uploads sence the rat rod go kart build
Makes for a good paint mixer
That is awesome
can you make a 2.0 green beest i relly liked it
Brilliant!
*also makes for a great weapon* !!! :D
And you can still use it as a bladed weed wacker. Do the lawn, then take it to the lake/river.
It's also a food processor, blender and drink mixer.
Amazing 🤩
that's pretty awesome, i might have to make one.
Use rubber raft. or inner tube.
excellent thumbs up. really helps a lot. thank you.
Best five minute life hack ever
It needs a steeper blade angle. Froth is not the same as thrust and three blades spinning in the same direction at zero blade angles produces no thrust
If you do ever take it out weld up a few different propellers at different diameters and pitches to see which one is best
Loop 9 MO on 00
This inspired me to turn my chainsaw into an espresso machine.
How do you keep it from bogging down ?
gah. wheres part two?! i wanna see it make the boat go go gooo
did you ever test it out in the lake?
There's no pitch to the blade , how well did it work?
This guy is a hella welder, 450+ vids on go-carts, dune-buggys, crazy dirt bikes etc...but no part 2 where we get to see the motor being tested. :(
Cool man
Ain't boat motor if it ain't on a boat. This is a weed whacker with a different cutting edge.
The bout motor is cool but would you relied on a truck company that went bankrupt twice? I would not.
About a 50 to 60 cc chainsaw motor an adapter it to electric outboard
Looks like the prop is backwards
Susposed to push not pull 😂😂 in reverse 24/7 what a moron ...good Try tho
I noticed that also.The question is, what's better for the angle drive as far as thrust goes?d(it's really easy to turn the whole thing around, and let it pull rather than push, depending on which way the foot is less susceptible to axial thrust from the propeller.
Just mount on front of boat
If he used on of the ones that has attachments he could make a mount using a bearing that fits the shaft and mount it to the back or front of a John boat
And change pitch. Or create multiple props to check speed and performance.
How much for the homemade propeller I have a mount and everything just need the prop to put on my boat.
*DONT DO THIS* without any reduction the 2stroke engine will not be able to work even a small 3inch prop in the water because it cannot achieve the required high RPM. also those engine are AIR COOLED and will burn out if run a long time >1min at high torque low speed.

So no video of it actually working on a boat I really wonted to see that
Me too dude ...
i wonted so many things
Ya me to
on the weekend you can always use it as a weed wacker
Why go through all that trouble, just take a threaded rod attach a trolling motor prop with just a couple of lock nuts, run it through a 3/4 pvc pipe, attach to any cordless drill you want, way more powerful than that, will push a houseboat
nice boat , but i think the motor goes on the outside
Needs more prop. That is pushing about 10 pds
Best vidios...😊😊😊
👍👍👍👍👍👍👍👍
2 blade prop 10 pitch is ideal ! Your 3 blade prop will burn up that tiny motor in NO time !
Some mixer you got there.
Looks like your prop is pulling instead of pushing if you mount this outboard apparatus on a boat!
My eyes hurt from looking at the welding
I missed the part where it was x-rayed and harmonicly balanced.
No pitch to the blades that I saw, no shear pin either.
higher angle on the props will make it go faster
Why are you grounding through the vise crank? Hope you didn't get arc burn on all that exposed skin.
The Indonesians do this but with ridiculously over powered motors, so fucking dangerous, yet so fun!
Did you put it on a boat for testing?
Just Had An Epiphany .... I'm gonna fill a tub with some cream and whip up some butter !! 😉
I'd like to see that. You should make a video. 🙂😁
@@jennyanimal9046 Good Idea , I'll Start Working On That !! 🤔
What socket did y'all use
Good concrete mixer?
After all this it still works as a weed wacker
Lol awesome
buen video
Sooo... ya never made it to the lake, or did it not work out ?
That was fun to watch 🤣🤣🤣
Nice
Amphibious go kart?
Cars and cameras fan?
What gearbox is used? What's the name?
Not bad idea. Prop needs more pitch. Take pix of different styles of props. The deeper the pitch the faster you can make it
I was thinking the same thing when seeing him start to weld, but on second thought the spin rate of that prop against a weaker motor probably makes it more efficient to have a less aggressive pitch. Could be wrong.
why don't you use that homemade propeller on the grass and make a video of it
So are you gunna test it?
Did u ever test it in a lake
Sweet
