- Save 10% off your first order - bit.ly/3DcyC9D Our Ariat Favorites - bit.ly/3bQ2D2M Jet Stream Adventure Boats sent us a scaled down version of their aluminum boat kit and it is only 6' long! We got a good price on marketplace for two old jet skis. We got the JetSki running before tearing it apart to make sure all of the parts we need work just fine and the engine was clean. Next we will fully customize the boat with engine mounts and cut into the hull wherever we need to add more parts. This is our fully custom mini jet boat build. Eventually we will build a custom mini trailer and trailer the boat around with our other projects.

Thanks again to Ariat for sponsoring this video! Save 10% off your first order - bit.ly/3DcyC9D Our Ariat Favorites - bit.ly/3bQ2D2M . This build is going to be wild! What do you guys think?
The thing that changes the direction is called a jetavator
Put a winch on it please
Hey dude, I have a tl1000 motor+ ecu + harness and a Kawasaki jetski 550 2stroke + harness sitting around my shop. We do led lighting not motorcycle stuff so if you want it let me know. I'm sure God wants to bless me, but I have to let go of old stuff to get new stuff.
We also have a ton of 1/8" acrylic scraps if you need windows.
where is the triumph?
You guys are seriously in my top 3 favorite youtube channels list. The creativity and awesomeness is unreal. Keep up the awesome work. Cant wait for the new shop
Thanks man!! We appreciate that!
lowkey my favorite
What are your other 2 favs?
@@nathanyamaha465 whistlindiesel and cleetus mcfarland!
@@ethanwhite1974 LFG for the Florida giraffe lmao he’s local to me 🤙🏽
I'm honestly really looking forward to the firetruck. That thing will be such a beast. I'd guess it'll be easier to accomplish when the new shop is built.
Oh yeah! We are looking forward to working on that again now they the weather is getting better!
@@-G-a-b-r-i-e-l your brain doesn't work very well 🤣
Oh hell yeah GrindHard. Been watching y'all for years now. Modern diesel power plant in ye ole' Firetrarch? That can always come later. Keep making ordinary lives extraordinary via extension. Your content slaps.
@@ChanceBeard I was thinking that too. Anything they got would be better than the gas one that's in it. Way more power.
Fire truck smire truck bruh check this boat way better but yeah yeeee
Lots of potential crossovers here. I'd love to see you work with Jet Ski Brothers and their V8 Jet Ski. Also, Cleetus McFarland has done a lot with mini jet boats and I believe he even has the same 6' hull waiting to be finished. Granted Florida is a heck of a haul, but he has been talking about an Alaska trip.
Aw yeh jetski brothers
co-lab would be sweet!
Yup, I remember when Cleetus got that hill when they shipped Kyle’s down there. I haven’t seen anything more about the Cleetus baby boat.
I'm pretty sure this is cleetus old hual
@@fullloadofcummins I don't think it is. GHPC had theirs a year ago, according to this video. Also the hull was labeled for them. Last I saw Cleetus bought a seadoo spark for the drivetrain and the hull was down at JL performance.
I think it's the same model, but not the exact same one.
Boosted Boys K20 jetboat 👌🏻
hey!
just some pointers right off the rip,
the kawi 750 is a great motor to choose because there is a lot of internet info on both the small pin and large pin versions, just convert over to premix and discard the pump and oil system, one little plate and your converted (they are reliable if maintained but no one does lol ) your carburetors are tuned to the restriction of the spark arrestor (vacuum carbs) (restriction=vacuum= tuning) so if you get rid of it for some china cones or something, then your "pop off" on the carbs will need to be lowered! always buy mukuni brand carb rebuilds... do not skimp on china kits... you will always regret it! also the exhaust is tuned based on where the water enters and exits, i suggest not monkeying or changing it up to much. there is usually one exhaust mod you can do to gain some free hp.
Hope this helps!
Great info. Marine engines (especially 2 strokes) are a different beast.
well i hope they will be doing some mods, because that is not a 100hp engine stock
@@jasoncrawford6257 very true!
@@jasoncrawford6257 yea like maybe 30 at best 😂
Amazing engine!
You guys are living my dream. Thank you for being so awesome with your amazing builds. If you guys are ever in Florida, specifically the Tampa area, I'd love to meet you all and say what's up.
Thanks man!! We appreciate that! Will let you know if we’re ever down that way!
Yall better bring that down to Florida n go boating with cleeter now!
That would be fun!
Gotta do the collabs! Yall need all the views!
I am looking forward to absolutely every project you guys are working on! That little jet boat is going to be an absolute blast to ride! Love the idea for the mini-trailer for the mini-boat.
Just an idea from a guy who really has no clue: Have you thought about locating the engine in the front of the boat and running the shaft back to the impeller as a way to improve center of gravity and maybe rider comfort? (doesn't everyone love having a spinning drive shaft next to their sensitive bits? 😁)
thats a good point
The reason every single jetboat has the motor at the back is because the more weight at the rear the better. because then the intake is easier to keep in the water which = less cavitation like having more traction on the water. i wont thint the weight balence will be that bad once you include the driver weight as a rearward bias is preferred
just read up on it actually, and a possible issue of too much rear weight bias is porposing. which is when while the boat is on a plane the front of the boat bounces up and down. this can be fixed by adding weight to the front, having fixed trim plates at the rear of the hull, or having adjustable nozzle trim
@@Louis_m9 - It's a lot easier to adjust the seat forward and back to adjust for porpoising than it would be to move the engine. My thinking is that the engine, being a small 2-stroke, is probably lighter than the human who will be piloting the boat, which is why I suggested putting the engine up front instead of the human.
You guys are 100% the real deal. It makes me smile just watching the enthusiasm you have, and no one could question your commitment when it comes time to send the finished projects - and a lot of the time, sending the _unfinished_ projects. Keep on doing what you are doing lads. If other people feel as happy as I do when watching your channel, then you should know you are doing something to be proud of, AND having heaps of fun while doing so.
The problem your going to have is the donor jetski has a molded in fiberglass pump shoe. You really need a bolt in aluminum pump shoe to make this work right in the aluminum boat. Otherwise you'll have to cut the shoe out of the old hull and rivet/fiberglass it into the jetstream hull
Yeah I don't think it's going to handle very well at all. But that's not the point!
He does have a lathe, and has shown he will continue to refine something untill it suits his expectations... I believe we will see him discover and address this issue.
Early 90’s tigersharks are well suited for transplanting into boats, kawis not so much. That hull is crazy small, going to be difficult to cram it all in there.
@@leebatt7964 ya an early Daytonas pump shoe would be fairly easy to graft into that boat. Being that they bolt into the jetski and fit in a rectangle hole
You should use that hull and put a 4wheeler or something inside and make an amphibious/ATV deal that floats.
Nah, that would wreck any usefulness of the frame. There is no jack of all trades vehicle, it just becomes master of none and suck. Cant really run same engine on land since jet uses water as coolant and there is no air flow over the engine. If they want to do something like that, it should be remotely driven thing that is its own unit, but it does not much sense to do so. That boat is already tiny and with this much power it will be dangerous to drive in any even moderate waves, so adding this amphibious system does not make much sense. Much rather build their own setup later on that is built for this transitioning, not that there is much use for one in Idaho far as i know.
@@Hellsong89 I was talking about the jet ski hull.
hi guys I've been following you for a few years maybe since you started making cars with motorcycle engines and I like what you Keep it up ok thanks a lot and a hug from Italy 🇮🇹🙋🇺🇲
With that jet ski body you guys should make it into an amphibious quad
Definitely going to have to add some flotation foam or something to that boat so it doesn't sink it looks so sick like it would be terrifying to drive can't wait to see how it works you guys rock
Agreed!
I dunno man there is a video of 2 full grown men in one of them things and it did alright, I would imagine Jetstream designed them to be buoyant enough on its hull design alone...
@@TheDuckumz The point is that if it gets upside down it's going under. Very much unlike a Jetski which is like a bubble and is pretty hard to sink.
@@bradley3549 Ahh, i gotcha. Yeah i didnt even think about that aspect
I can’t wait to see the end result of this build.
I wonder if Ethan asked all the girls he see how much they weigh? And if they are interested in some weight reduction. 😂
I want a pile of snow like yours. not only can you pull out a snow mobile or dirtbike, but you got friggin jetskis in there. love these mini jet boats, you lads are gonna have a wild time in this
You guys are so cool man. Always building some of the coolest toys out there!
Remember to put some wearprotector on the bottom of the boat! I remember cleetus mcfarland putting some whole boat wide and long plastic thing under the boat.. it really has saved his boat mamy times.
I'd love to see you guys meet up with Cleetus and his jet boat crew. Looking forward to more of the 6x6 Ranger. Always great content here🍻
A race for sure! - ruclips.net/channel/UCh8f8vssLddD2PbnU3Ag_Bw
I belive the water jacket in the exhaust is actually a preheater for the engine so it can get up to temperature and not shock the engine with cold water.
Correct, it will also have the effect of slowing the gasses down, reducing power.
Find a copper/ceramic coating that can help insulate heat loss.
100% correct. Hitting the cyclinder sleeves with cold water leads to cracking.
That tiny boat need a wooden vinyl wrap!
You should watch Cleetus McFarland and watch his videos on his jet boats. I think you can get smaller jet controls on the rear end that does the same thing as the jet control you have. Great stuff.
I believe Cleetus has one of these really small hulls too but hasn't done anything with it yet.
@@momolovesyou9969 I don't know if Cleetus would ever build something that is this small tbh. He is like 6.5ft tall and him fitting in it would be a nightmare and extremely difficult knowing this. But nonetheless, I think they would get some useful tips and ideas for their build from what Cleet and Jackstand have already built.
@@brandonhaines1920 ruclips.net/video/fpJ6Rub_gm4/видео.html that's the link to the video, they show it towards the end. like I said they haven't done anything with it yet, there were jokes about it being for Garza. Cleetus is into RC so maybe a large scale rc boat would be cool. Either way the grind hard guys will do something sweet with it.
It's about time you guys got to that project. When your done you should go boating with Cleetus McFarland.
what if the seat and gas tank were above the shaft and the engine was between your legs? mid engine style, since thrust is so high mid weight balance could help.
I was thinking that. Engine way up front, sit on the shoe with the shaft between your legs. Foot throttle.
I think the balance and handling are going to be way out of whack. But I know as much about jet watercraft as what Mike Finnegan has taught me.
@@1one3_Racing dog boxing it like a van will also allow it to be heat insulated, quiet, and padded for some grip on your legs to keep the driver in place. fuel lines exhaust, and shaft could all run in a tunnel.
1.37 million subs is rookie numbers for this quality content.
Wed and friday two separate builds. Sweet. 👍👍
Build an amphibious land/water jet ski with light suspension and wheels!
Another thing to add .. Try to source a Polly bottom slider for the jet boat. It adds strength and allows it to slide over rocks and sandbars etc...you can see what I'm referring to on Cletus McFarland's YT channel.
The thong on the back that changes the direction is called a Jet or Jet propulsor. Good luck getting it to fit!
Would be cool to build another small boat out of the stripped jetski, it floats right
The old jetski hull would make a great amphibious build base.
So happy to see y'all build a mini jetboat. 3 channels have started one and y'all will actually get it done. Can't wait to see finished product! Keep up the great work
Can't wait for the Cleetus McFarland Collab!
honestly i really think yall should get into dinghy racing. It would be right up the alley of this channel
For some reason y'all haven't been showing up in my feed lately. However, I'm grateful to look you up and see all this awesome content!
You guys are killing it! Im excited to see the rotary trike and 2jz lawnmower finished. This boats and the dream camper are gonna be a killer combo. Keep it up
I’m so glad someone from Michigan won!
MAN !! I want to come play with you guys & your toys, being a fabricator, I love to see everything you are doing.
The thing in your hand that helps with the staring is called the bucket and it also will help you with reversing
Ah, makes sense!
You guys should definitely make a new power wheels mustang GT build soon!
the Barbie mustang is actually a 2005 mustang model.. ,
I seen a newer version of a mustang power wheels ,
would be awesome if that happened! and good luck on finishing the other unfinished builds.
Just put the engine in the front and extend the shaft instead. just build a small tunnel for the shaft with the seat right above it.
Agreed, the shaft has length for a purpose. I would imagine it has to do w/ fluid mechanics, preventing parasitic losses. The engineers sacrificed power loss in the longer shaft for a good reason, IMO.
Hey guys just wanted to say your part in the car and driver magazine for April is sick 👍🏽
This is gonna be sweet. If you guys need to source any random jet ski parts let me know. I used to work at a motorcycle salvage yard that had a bunch of them.
I love that Schecter Hellraiser FR on the wall in the outro!
Every engine made by Kawasaki is truly magnificent!
You guys build some of the coolest toys ever
Now gotta do some type of river/waterfeature course on ur property this summer to rip that thing
When he knocked on the boat with the rod it sounded like law and order was about to come on 😂😂😂 9:37
Imagine a cheeky shot of Nitrous tucked back there for emergencies!
Maybe that snorkel WILL come in handy. Considering how far into the water you will have to back in to launch the tiny boat off the tiny trailer. Lol
Ahhhhhhhh i absolutely cannot wait for the launching of this boat from the back of the power wheels
Sounds sick
Absolutely!!
Omg you guys rule .... how fun utube pop culture 👏
BEEN WAITING FOR YOU GUYS TO GET ON THIS JET BOAT GAME
Sounds like a lot of fun .. remember safety comes first ..
I think maybe that little boat will need a Wing to hold you down on the water. If not that put wings on it, because Its going to FLY...LOL..HAHA..I used to have jet ski and they flat ass fly with fiberglass. Let alone on thin Aluminum...LOL.Cant wait to see this Going..Great Video Guys..
If you can do this and do a video with Cletus McFarland when you compare each other’s boats. That would be epic
Y’all gotta go out to Florida and jet boat with Cleetus! Hell yeah brother lol
I love living so close. I get to see some of this stuff before it's released. Thank you guys for being awesome. And thanks again for being good neighbors (2 miles down the road) but its awesome to see y'all rip up and down the street every once in awhile. I have a second property near lumis/tonasket. Completely flat if you guys ever want to play. I have plenty of toys and custom go-karts too!
Yes!!! I'm so happy you guys are finally building this 😁
Take to Florida and go jet boating with Cleatus McFarland. You guys should totally race the 24 hours of lemullets
Your content are my "I love the internet" moments!
Congratulations William!
was having a bad day then you guys uploaded and it immediately got better
Can't wait to see this thing rip some creeks
You forgot to write, part 1😄😄. Greetings from Greece. Thumbs up!!
That thing is going to be one fast little boat!!!!!!
Will this super secret trip happen to be in MOAB?🤣
you should put that jet ski motor on a dirt bike frame! 😁
I have been waiting for this video for three years!
You guys are very one of my top favorite youtubers. Been watching you from very long time. Love from Nepal.
I'm not really a merch guy but I might rock a grind hard jersey!
This is perfect to pull behind the barbie camper!
Precisely!!
Hahaha! I have that exact ski with a punched out block and the whole thing is as clean as your engine! Want that hull so bad now!
Trailering this behind the van project is going to be crazy ! Mini bikes mini boats and mini atvs 🔥🔥
You should get 1 or 2 of those RC Turbine Jet e
Engines to put on that Jet Boat ... Come on DO IT !
You guys better be painting that boat pink like barbie camper! That boat will be sick when finished!
Of course!!
Guys don't kill the ski-do Hull, build something out of the base, 'New project' thinking 75hp outboard 😆🔥greetings from Trinidad 🇹🇹
Beating Cleetus on his mini jet boat build!
Feel a mini boat trailer build on the way too
I think you should mount the engine as far forward as possible so you could ride it sitting in the back and also standing up and have more control
OMG I love that jetski. When I was 9 we had the exact same one with that same color scheme.
I'm so happy to see this RUclips channel grow! You guys deserve it!
Please do a Barbie semi if you can find one somehow, with a trailer. FLatbed or fitted for the boat but drive around with a custom semi boat and trailer all minis make the trailer big enough to fit a few of the other toys as well and it actually be a mini, miniature toy hauler.
Legends! Can't wait to see how ridiculously dangerous/awesome this boat is at full send.
❤️❤️ ❤️❤️ That's awesome! I think they run tiny race boats in New Zealand. The track is literally a 3' deep trench filled with water. Guys will wreck out and just stand up waste deep in the water.
I would love to spend one full winter somewhere, I live in a hot dry state my whole life, I need a change.
If you ever have a child it will be the happiest child on the planet!
Haha! True that!
I want to see you at the Freedom Factory. Need to do a collab with Cleetus
Y’all need to make the shell from the old jet ski into a four wheeler. Then tow the jet boat behind the four wheel boat
PLEASE PLEASE SAVE THE JET SKI HULL AND PUT IT ON A ROAD LEGAL SCOOTER. Please please do this its been done so you might not do it but its perfect for you guys
Love it! Too bad we were not there to remove the wasp nests for you.
You guys have been uploading so much, I can't even keep up with all lour videos. 😄
Ariat is an amazing company
Y'all should do a mini rock bouncer
I can't wait to see this in the water, nice addition to the mini collection!
Liquid cooled exhaust is to keep the exhaust seal from melting and letting water into the hull.
That boat is mini, but my God that head is huge!
Total pain to work on jet skis engines in the hulls, but in a boat like that they would be a JOY
That’s what I was thinking!
Can't wait to see this on the water
love the tactical toolbox hat 👍
