Put a turbo 1630 in a spark!

Where's the V8,

Actually a pretty good ski if you don't want to learn to ride a jetski.

You guys make it look so easy

Great acceleration, smooth turning, doesn’t feel rocky or choppy yet smooth and fast?!? *IS THIS MY DREAM SKI?!?* 👼😇😊

Spark with a 951 lol and the spark engine in an xp would be fun

Yeah chuck an 1100 in it. Too big though maybe? Dunno how much room there is. Anyway chuck something 2 stroke in a spark. Would be fast! Or maybe that 1500 kawasaki motor, did you guys ever end up using that for anything? But again, might be too big. Suspect that spark motor is pretty tiny and the hull is made to suit. Ideal hull for a swap though, easy to split in half.

I had a go on a friend's trixx one time, the most enjoyable thing was just the lightness. Taking it out on waves it just flew out of the water, great jumps. And of course the "water wheelies".

Try $600 AUD to get a tune upgrade, both Seadoo and Worx here in Australia. That’s why we are stuck to the original firmware, just too expensive.

This wet bike is so stupid. i need to ride it, yesterday.

where's the carb book?

Put it in the water

god damn it, 1100 swap it! DO IT NOW!\

mph? hp? need answers

360 cam looks like a video game and it gave Jason a tiny head LOL

I'm looking to buy my first jet ski. I don't have much money but there's a 1974 sea jet for$2300 in my area. The guy said it's pretty nice. Is it a good ski for my first one?

Build a bananas turbo spark trixx would be sick!!!

That Jet Jon needs some trim tabs (down trim), lol!

Those old sea doos had so much better potential, but no reliability. I got sick of ripping my pumps out day after day. May I suggest finding a 1999 Yamaha waveblaster800. A few were imported but not many. It has very similar handling characteristics as the hx, but typical Yamaha reliability. You could easily put a 1200 in there and would be an hx eater. I found this video by googling seadoo xp 1209 swap to see what others have done because I really like the shock in the seat, but actually just answered my own question. Who’s got a Yamaha Waveblaster800 for sale?

Seadoo Sparks are awesome lake skis, fun to throw around for sure!

How does it compare to a waveblaster as far as speed and handling

The way the camera records almost looks like computer generated.

I'm in for more spark content. I'm guessing that one was a 60 as the 90 should do 50 mph. I've been toying with replacing my aging 787 gsx with a spark one of these days.

how are u guys recordin that? looks pretty nice!

Nice

What was done for the waterbox. Are you running the water injection? Just did the same swap. Hopefully you respond. Not finding any info on this subject

rocket

Sounds like it has a mild cam in it

A squeaking ls is never a good thing

I hated the power valve setup.

I have a 05. Just now having problems.. im trying to learn these lol

This is the first ski on the course that looked proper fast. Maybe it's just the Insta360 wide angle effect, but it does look proper quick.

Would you guys ever make the reduction gear to Yamaha coupler for sale as a kit ? I’m really curious what LS set up you’re running ? Cam specs ? At mid 5k rpm anything in the high 230s+ duration and/or wide Lope separation you are just barely touching the top of your power band. I used to work as a tech at a few major speed shops around here, I first hand saw the before and after in hundreds of setups to what works or changes. In that tight of a bay the best manifolds to run would be a C6Z they are intended for the 7.0 LS7 but are double walled and bolt up to every LS head platform.

its like the hayabusa of jetskis: too much power and big asl 😭 kinda looks like one too

Love that ski mate, wish I had time to build one.

Camera angle might be making it look more intense, but far out it does look ridiculously fast.

Awesome Video as always!!! Are you done with the V8 Ski?

Best thing: Take sea-doo (any 90's) put in a good motor -> enjoy

What's up with that new v8 turbo??

Bro stop the music we want jet engine sound qnd life sound not dumb music thank you

Hell ya more footage on this thing be nice to see it compete in the high 80’s with the brand new skis

Need work We Ran GP Yamaha with a seadoo on 13 psi charger 93MPH back in the days You should be at least over 90

That circle track course looks intense! The narrower your surroundings the faster it feels driving through them! It’s like doing 100mph down a narrow residential street! Everything just whizzes by! Awesome video and that thing rips as always!

That was one of the cleanest turn around pole maneuvers I have ever seen!

Love me some jsbrothers videos

Dope af!

Definitely on my short bucket list for an engine. Hard to find a decent FX SVHO in AK though that’s even remotely fair priced.

Thank you to sbt for the starter i bought for 150 and lasted 1 season and granaded metal on the inside. This time im going with blowsion. Atleast it had a 2 year warranty. That 1200 is bad ass boys!! I would love to ride it and i hate couches
