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?

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

I would run a solid roller 4.8 turning 8,000rpm.

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

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.

"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.
