Possibly the most aggravating water crafts on the water. However we finally got our hands on one, and what are we going to do with it? We'll try to resist the sudden urge to crash into every boat in sight. But honestly been looking forward to this for a long time! The Seadoo Spark.

Fastest lap time ski is back! Can it beat the previous lap record it set a few years ago. Nothing better than testing new parts on the fastest ski around the jetski brothers test track! The Interceptor (engine swapped gp1200r GPRSHO) returns. 1.8L supercharged Yamaha engine swapped gp1200r. Was the largest production pwc engine ever made (by displacement) in the Yamaha Waverunner gp1200r. Jetsk...

Watch Jason nail it while collecting test data on the red wave blaster. Top speed lap time and a terrible disappointment. Shout out to SBT for helping us with this build - www.shopsbt.com/ Jetskibrothers website - www.jsbrothers.net/

Rumor has it that in the early 1990's Yamaha/wavrunner developed and manufactured a personal water craft that stands the test of time and will forever be considered the best mass production pwc ever made. The WaveBlaster 700 commonly called waveblaster 1 or wb1. On todays adventure the brothers will reclaim one of the legendary waveblasters from the brambles, revive it, and return it to its nat...

Just an old fishing boat with a trolling motor. Bwahahaha! Taking the market place jet jon boat for its first runs. It is a 14ft aluminum fishing boat with a 1999 seadoo gsx engine conversion. The 951cc seadoo power plant is rated at 130 horsepower.

Jetski companies should make a turbo V8 ski from the factory. Like boss hoss motorcycles did with Corvette engines in motorcycles
A draggy is the app thing that shows 0-60, 1/4 mile, etc
Hey i have a 1994 kawasaki xi 750 ss and in the water it wont rew over 5.5k.rpms. on the trailer it rews just fine and all. As soon as it hits water it cant go.over 5.5k. do yoi know something about that?
Crazy to think you are literally sitting on an untamed beast with ridiculous power🙈🤣🫣
Dilectric grease!
Seems like the limitations will be in the drive line since that motor pushes so much power. As before you were shredding the impellor blades and housings. Keep up the good work, eager to see where this can lead.
Proves that EVERYTHING can be LS swapped.
anyone know what lake this is?
What are you doing? its totaly not as fast as a normal yamaha 4 cil engine with turbo. and the v8 is not reliabile?
Should do a r1 swap
I have a 1999 Yamaha GP760 pretty much stock any upgrade recommendations to make it faster?
A V8. Clearly.
Nice!! I built mine back in 2004!! 155mph is something everyone should experience on one of these.
You should l9ok into mercruiser engines or at least their manifolds which are water cooled you need to keep up the hard work but definitely look into them and see what boats use for cooling plus mercruiser uses alot of gm engines. Hope tjis helps you guys on this awesome journey.
Looks sweet, jet ski porn, keep up the videos JSB 👍
I’m sorry please don’t show machining like that. It’s unsafe and an embarrassment to the U.S.
How do you guys mate these engines with the driveshafts? Where do you get all the parts needed for these swaps?
Keep going, this is why I sub
SOMEBODY PLEASE DROP THESE GUYS A GOOD LS MOTOR! Come on, yes you the guy with like 10 in his garage. Help us out!
Keep it up, came here for the V8 Jetski, that thing is insane....
I am thinking that maybe the pistons are bound up because turbo charged and blower charged engines the rings need to have a larger gap 😊
You should get a Steve Morris engine SML or SMX twin turbo made for a jet ski because boat engines are different from car and truck engines because boat engines are under constant load and car and truck engines are not so some of the internal parts are way different, at least do some research on it it will help you in the long run 😊😊👍👍👍👍👍👍👍
thanks for the update.

Head gasket
I want one.
Aluminum truck blocks were L33 designation . Only made for a few years in trucks and suvs .
Hit that 👍 🍻
HydroDrag skis use the older version or the most recent Garmin GPS 73 for top speed runs. It's waterproof, has speed history, top speed, etc
Ring gap?
V8 Ski! Looks way cool and floats good too! NO marine exhaust, No Windage tray, No oil cooler, Cooling system not pressurized correctly, Too lean of tune, too high of RPM for V8 for extended time, Improper bearing clearances for High RPM, NOT sufficiently crank shaft torque loaded... Even if it doesn't work, it will sometime in the future, I'll buy one! Let me know when ya get the water outta the OIL and fix the blown head gasket...
Been following this from the beginning. I would have given up a very long time ago. I don't know how you have the will to continue.
You guys do good work. Love the videos
Does this have a dry sump? Its an oiling issue for sure.
Ur gonna need to dry sump it or make some crazy custom baffles. You will constantly starve the oil pump for oil. Happened to me a lot when circuit racing LS engines. I’ve had the same issue with a 5L build. Also cooling is a big thing just from the way the coolant flow is on these engines. I switched mine to reverse flow so Coolant enters the heads and flows towards the block. Much better for consistent power when heat soaking
Dry sump is the only way to be sure for extended service intervals or if its welling up in the head. You need that extra capacity, scavenging and lines from the head...
I would run a solid roller 4.8 turning 8,000rpm.
This guy LS's.
Haven't had your videos pop up in my feed for awhile, good to see you guys again.
Don’t give up. Very impressive
Have you said your prayers for the v8 jet ski today?
i assume you swapped the cam into the 5.3 and acting more snappy is probably because the cam acts bigger in a 5.3 than in a 6.0 is how that works. or like u said the 6.0 was messed up for a bit
The 4.8 is a stout one. I’ve seen some nasty built ones
Keep it going! We know you can accomplish it. This thing is awesome.
Ok so I have lots of info for you on your engines. Depending on which 6.0 you had it was likely 9 to 1 compression. The lm7 is an iron block 5.3 that is 9.5 to 1. The aluminum 5.3 is an l33 and is 10.5 to 1 compression and almost 200lbs lighter than the iron block ls variants. So if you went from a 6.0 lq4 to a 5.3 l33 it's possible that the added compression along with being lighter would be faster than the low comp 6.0 iron block. LS engines have to get pretty bad to lose much HP from wear. These are all gen 3 LS variants. The gen 4 stuff would take more time to explain
Also hit me up if you have any questions. I build these engines all the time for work, and would love to help. Also I'd love to help yall figure out your gearbox issues mostly because I want to build one of my own. Don't get discouraged. This thing is super cool, and the only reason I found your channel
Someone can use google! Congrats
@tookiefranks7746 someone has spent 15 years as a tech, and builds these engines as a hobby Jackass
It is called a Dragy.
please give up on it. I love your content...but this ski was never going to work. Trick a 1.8L out and call it a day. Tough love, but people don't subscribe for constant failures...they un-sub.
Counterpoint: don't listen to this guy. Builds aren't always meant to have a happy ending and nice conclusion. Builds are a journey!
dude unsubscribe !!! no one will miss you .... we are hear for the content win or loose we just love watching a v8 ski these guys have put their heart and soul into this ski...and if they did stop your the kind of guy that would say i knew it would never work !! keep going guys the rest of us will not unsubscribe and we appreciate the entire build ❤ 💪 we would only be let down if you stopped the build 😊
You know I'm right. "Insanity is doing the same thing over and over again and expecting different results."
@@mjethier go burry your head in the sand if you dont like the content.. go to another channel that you like and stop being a debbie downer man ... and no your not right why dont you post something you have worked hard on so we can tell you to just give up i will be the first one to post
"If it was easy, everyone would be doing it"
Thanks for the vid! Hang in there man, you’ll get it dialed in!
It sounds like my boat, lol
How does it feel at slow speeds? Does it feel tipsy or too heavy with the v8?
Does not break...
Such a good build. Persistance pays off, i know you can figure it out.
