- This is not click bait, Ls v8 jetski is on the water for its second test ride! Racing a seadoo xp 800 and doing some gps top speed testing. Revealing the weight of the v8 jetski as well. V8 engine into Yamaha waverunner fzr jetski pwc.
big thanks to Holley helping out on this build

That gear box sounds awesome, glad you properly filled it with gravel
You are going to be limited by the max RPMs of the V8 compared to the 4 stroke Jetski's. You could make it a top end monster by changing the gearing and using the torque of the V8 for the hole shot.
The v-8 is a 4 stroke.
@@CaptainDayne yeah he was jsut saying even the new 4stroke skis make 11-12k rpm
obv he didnt call it a 2stroke lol
Now you need a LS7 427 in there.
Kawasaki already make a 350 HP monster. Why bother. Plus they are engineered to handle. THIS will not!
@@tvdinner325 very true lots of the new skis are able to make 700-800hp without serious modifications
Even though I knew what this video was it still tripped me out to hear a LS Crankin up on a jetski
Lol I love that it sounds like a Silverado when you crank it up.
I mean stock v8’s are never quick off the line but they are locomotives on the long run. Love the mod tho I mean I am really amazed. Can’t wait to see where this goes
That V8 sounds great.
Wow, impressive top speed results, that v8 ski turned out so sick. Your builds are epic
Know of a couple of Sea Doo's with Rotary 13B engines, would be great to Match them in a 1/2 mile "Drag Race" against the V8.
Back again with the proper crew at jet ski Brother's 😉😉😉🇨🇮🇺🇸🇨🇮🇺🇸🇨🇮👍👍👍
so i can fit my vr6 turbo in a jetski, nice. Great work.
Holy cr×% that is a jet ski! Nice job looks like a lot of fun!
Kudos to this guy, loves his ski’s and built something so special. If seadoo or Kawasaki made a V8 ski I’d definitely buy one 🤙🏼
Awesome job guys.....but what happens when you bail and the ski flips.....are we just crossing our fingers and saying our prayers, either way I love it and that thing is the ultimate jetski
I was on some supercharged jetski last summer, and it didn’t go that fast, somewhere around 60-65 depending which one of us where on it haha. Very cool project!
Pretty cool project but really, new jetski engines make more power and rev higher than that 4.8. Needs bigger pitch impeller to take advantage of the extra torque.
Can't wait to see it on the track!
Watching the wrong channel water //// track aaaaaaah Dow Dow🤔🤔🤔
Great job! You have awesome fabrication skills!
Different gearing and an aluminum-block LS (any of the car LSs including the LS4, or the LH8/LH9 all-aluminum 5.3L truck engines, which are my personal favorite and of which I own 3) would make this thing the baddest around for cheap. Awesome swap, sounds great and is super-interesting.
Try to get a 6.2 all aluminum ls3 🚤💨and take off the mufflers it’s too quiet 😁
Open upswept jet-boat style headers to sewer pipe tips.
All depends on how wild he wants to go, gmpp he the 454 in aluminum and iron so there's 7.4l/454inches vs his 4.8/283 (?) There's 7 liter ls7s but both of those engines are 15 18k dollar engines
@@MF11283 I'm sure some sponsors would help out. Channels getting more viewers.
Cheapest option is the 5.3 all aluminium block used in 2007 and up Avalanche and Tahoe's/ Burb's. Delete all that DOD/AFM crap though. Cut about 200lbs in that setup vs the iron block. The 6.2 is the ultimate if you can afford it and would solve that bogging issue with that 4.6!
I think the LS4 5.3 from a FWD Pontiac or Chevy is the hot ticket for this application. They don't have a starter mount on the block, so they don't get used much for swaps. Price is low for an all aluminum engine. Low profile intake is already reversed and they have a smaller diameter flexplate that may help dropping the engine lower in the hull.
Yea that'll get you there, great build
All that and a bph free water bottle as a catch can? I like it alot!
The sound is awesome wouldn’t not change for nothing else..
I love it!! Lsx the whole world
Sounds wicked!
I love hearing that little V8 roar
LC9 all aluminum 5.3
Love this with all humanity!
Love the v8 content you could do the v8 ski vs all of your other skis also a quick idea 💡 if you change the gear ratio. To 1:1 i could be a hell of a lot faster
I totally agree
Always wanted to see how a rotary engine worked in a waverunner. The high revs might get you a higher speed. Where the v8 more torque. Impellers will need to be played with either way.
There’s one with a hyabusa engine I believe and I think it might be supercharged… that bad boy is fast
I’ve wanted to do something similar, looks fun
The GMC Envoy Denali and LT/EXT Trailblazer had an aluminum block 5.3, and (at least for my 06) 243 heads, and is probably going to be the least expensive option...(results may vary). That one is about 300hp stock, and an LS2 cam adds about 40hp with no torque loss below 3500. If you're running the water pump still, ditch it and free up a good bit there. And if you wanna get nuts, a LSA blower will run off the truck accessory drive with a few adaptors.
Would love to see more of the R.O.B
So much respect for you for this build. So cool!!
Thats awesome dude, Kudos
Got excited when the alert went off 👍🏾 can’t wait to see the #’s
This lit I’m trying this I’m in New Orleans watching this 🔥
Is there an way to add a water cooling loop to the transfer case? maybe an external heat exchanger and small oil pump? Use a cooling line from the jet pump?
said that a while back. All they need is a aluminum tube that makes a couple passes through the gear case. It would def help. Couple rubber grommets to run the pipe through and I bet it would cool it.
Where there is a will, there is a way!!
Stop trying to make it a seadoo.open loop is better at cooling
Next thing you ask is to add a carbon seal
@@floridaman1776 😂🤘🔥
4.8 LS is the highest reving engine. It makes perfect sense!
Funnily enough the biggest LS has the highest redline (Ls7 at 7000). Valvetrain limitations.
A cam would help that big time. If you need any help on the tune let me know. I have tuned a few swaps with the Holley terminator. What Rpm's are you turning and what is the limiter set at? Make sure to watch oil pressure on long runs of high RPM's that oil pan is a bit small for that.
no doubt there's a reason 'every' ski manufacturer water jackets their exhausts - without the ability to force cool air (without any water) in there everything just gets hotter and hotter - amazing achievement so far though :)
Might have to use a soaker hose to keep a mist of steam trailing out of the engine compartment!
I would like to see one with the 80s vintage 3.8L Buick V6.
Sounds much better this time.👍
Nice setup!! I think you will get it all figured out!!
I almost triple power on my jet ski . the jet pump can olny put out so much . increase the pump diameter and pitch right along HP and torque increase
V8 jet ski brothers ..there's no going back now lol...
Yes, an Aluminum block!
Love the series! I would love to see you guys bring jetskis back to the mainstream for something other than fail videos.
You can definitely up the hp of the 4.great
pretty cool man
Such a cool build. It sounds so cool.
Impressive build. Quality work.
crazy!!!!!!!! BADASS!!!!!!
Boss-Hoss Jet Ski
Sick build fellas
It's beautiful, it's wonderful, it's a, V8. 👌
awesome job dude
sounds good looks good
what a fun projct
i've seen other v8 conversions
yours looks the best so far
If that's a 4.8 iron block then changing to an aluminum ls would definitely save some weight
you are brave to be trying to steer that beast going that fast!
May be sound on the water, but I don't think it sounded right. I don't know if it could take any timing, but I'd start with a plug inspection. I would have to consider a prop vs pump, if u wanna go really fast.
If you tune it right I don't see why you couldn't get 169.7 out if it lol it takes a while for it to get up and going with all that weight but once it's going it's going 😁
These skis do 67-68mph all stock with a 210hp engine.The problem with getting a V8 to perform better than the original 1.8 4 cylinder is both the extra weight and the low engine rpms.Your going to need either a huge prop or a much more aggressive drive ratio to get considerable speed out of this thing.At the rpms your turning the stock 155mm prop is not moving enough water for respectable speeds.To really get speed out of these we turn 160mm props to 10,000+ rpms and 30+ psi.Every 300rpm higher we rev them is worth 1mph and every pound of boost we push is worth another mph
Did you ever think about putting it in SUV hull? You could always put a prop on it instead of impeller like the original seadoo. would be unique
Fuck I love the sound of it! Well done guys, awesome build!
Sounds good
Still need the Holley GPS Speedo
I don't know what impeller you are running but the pitch of the impeller is important for hole shot and top speed. You can re-pitch the stock one or get an aftermarket one to help dial the ski in.
Yeah no shit. Like they don’t know this. 🙄
My 1200 does 63mph. I think most newer skies can do 70 or close to with a tune
I originally asked about how the weight differs with the v8 from stock or factory , but now I wonder about fuel consumption differences also!?!?
So exciting boys!
Ever thought about o Mazda rotary engine, no rev restrictions
You should see if you can get Texas Speed and Performance to sponsor you they can build the engine you need !!!
You guys definitely need to upgrade the prop better yet install the double prop.
Oh yes the clsssic sea doo rattle at idle lol
You guys should put twin turbo 2 better then one lols or a supercharger and make that 2
2 turbski's and Six or Nine NOS bottles will give this baby at least 12 more HP. But unfortunately it will be to heavy and sink to the bottom... So you will have buy 30 plus bottles of spray foam to fill the entire hull.
Well done guys.
Get Jacob to do another gearbox with a bigger gear from the crank to a smaller gear on the output shaft. More top end 😬
That sounds terrifying. I'll take 2
I wonder if the seat gets warm , I feel like it would
That thing sounds SO good!
I feel like there is vast room for improvement there.
@@foreverendeavors6210 fr just sounds like a normal jet ski this video sucked😂
@@jacob1423 Not at all really. Did you actually listen at the end when dude on the XP was parked and held the camera when homey rode away from him? Sounds totally different out the back than when hes riding and holding the camera.
@@jacob1423 it's a stock 4.8 though, imagine a all aluminum 6.2 with a monster cam, some 40 series flow masters, that would be one sick scenario 😳
im guessing the 4.8 is what is hurting your hole shot as those motors never were very powerful down low, a 6.2 or 5.7 aluminum would fix alot of that, especially if you get a good spec'd cam shaft in it. It is extremely impressive how well everything is working. Nice work!
IDK how much he wants to spend, but he could swap it for an aluminum 5.3 from a trailblazer trailblazer. It would be very cheap.
@@danr9584 your nutz if you think anything trailblazer is cheap , them trucks still go from 10k to 15k . You mean ls aluminum truck engine !
Thinking through the torque curve, seems you have less torque at the lower RPM band and as the RPM rise, torque builds and the engine gets into its performance range. If you know someone with a dyno, they might be able to help with some visuals. Just my gut and 2 cents for what its worth! Either way, keeping up with the XP on a V8 is bad ass! There's sooo much more potential in this thing. Great work!
Funny thought... Diesels produce a lot of low end torque... Next build idea? :-D
Do we need a oil cooler for the gearbox you think I don't know
Next test run should be 75 ///80 mph I reckon 👍👍👍🇨🇮🇺🇸🇨🇮🇺🇸🤔🤔
You guys inspire me!!!!!
Not a fan of sit downs but I am a huge fan of this build and have been following the build for a little while you are a mad scientist in my eyes. What type of pitch did you have to put on the jet or is it stock I missed that part?
I think you should cam and super charge
Get some braided line for the oil lines
I got a 5.3 all aluminum
I would think a 3.8 v6 out of a buick grand national would make a jet ski fly
Just get a 5.3 crank and ls6 cam and you will see some good gains no need to change the block.
Doesnt sound or look like she got 100% throttle to me, and possibly a miss? Pretty cool btw.
Sick God bless
A temp guage would be handy
Aluminum 6.0 or 6.2 it will drop weight and make way more power.
Does this have a marine cam. I think that would help. And some heads
GET IT TUNED
How many smiles per gallon are you getting there bud?
😂🤠👌SPG! Biden isn't giving it the green energy stamp of a approval till he owns part of it
It might be a water flow problem into the jet pump
I saw the first movie it was called Death Wish
Ls motors are like Frank's hotsauce you can put that shit on anything
pretty sure the gmc envoy came with a aluminum block 5.3
Awesome bro!! Standard FZR jet pump?
