V8 turbo ski new engine 

I love that this project started as a “Can it be done?” sort of a deal and thankfully didn’t stop there! It has been so fun to see the different iterations, failures and learning opportunities that have come from the build process. Keep it up please!

Thank goodness the junkyard always has at least 5 truck ls engines at all times for less than a jet ski engine.

This summer is going to be sick for the JetSki brothers!!!

Thanks for telling us about the pushrod mistake! So real. So funny, too.

This dude is doing some insane stuff. How is his channel not bigger

Looking good. Way to think ahead and not just toss the aluminum block in there. Well done with the build and well done with the video.

You’re a wizard!! In a trance watching you work away

I'm impressed more dad words weren't being used.

Finally!!! 5.3 all aluminum block yippy!

Nothing like the V8, merry Christmas and big thanks

Wow great job mate us Australia’s love it good luck 👍👍👍

2:45 That's a lot of bolts 👍 Lol... no pushrods ... I thought it sounded a little funny turning over. Hey, at least your pistons aren't in backwards ! 8:19 I'm probably wrong, that that sounds like the timing is off. 9:00 Hoooray !! I was Right ! Awesome video. That montage at the end was epic, also !

I like how the bellhousing goes on with like 45 bolts WW2 style. "That ain't going nowhere".

I feel your pain it's always the little things that make you want to pull your hair out And I don't have enough hair to lose anymore Thanks for the video it was really fun To watch And I don't mean watching you struggle Just the process of putting that motor together and into that ski awesome job👍🏼👍🏼

Dude. You're the only one that has done this. Please keep going. By the way I have a 500 hp 454 bb jet boat so I love this channel

I excited of how much this channel has grown and the level of the content

Tight real tight

MERRY CHRISTMAS JSB AND FAMILY!

Totally unexpected video !!! Let's GO !

I love this channel and your builds.

I found out that all aluminum 5.3l LS engines used are about $2,000 average in Central Pennsylvania this year. I was like woah??? Had no idea. Last one I had was in a 2005 GMC Yukon XL and it was an awesome engine!

8:30 seconds in and I'm feeling the pain😊

Be good to see it on the water again ..

Always pushing the boundaries!

Just want to say that OHV engines with no pushrods mounted actually usually got pretty good compression. The airflow numbers through the heads tend to be kind of bad though... 😮. But seriously, you did a great job as usual and I liked the compilation. Merry christmas to JSB!

Absolutely fantastic… V8 Jet ski. A dream come true.

Another awesome video! Keep up the good work Josh! Can’t wait for winter projects!

Happy holidays . I will be looking forward to seeing the V8 Jet Ski on the water once the weather gets warmer , . I love your videos .

Thats what I'm talking about !!

You should put a V8 in one of those little jet boats that people are putting jet ski engines into.

Awsome vid man

Smooth noise,,❤

You could hear that in the way it was cranking at first.

glad too see everything working again ,them ls engines make Good power for 5 minutes then break needs a 2jz

You want a Texas speed 427 in that thing LOL

I wanna see another beater video lol

Gday Josh, We use to have a Fastlane 40 down here in Oz with two 454’s, Merlin Heads and associated fruit. We pretty much went everywhere at full noise and went through our fair share of engines. Got pretty good at swapping them out. 😁 I know the feeling of spinning a bearing due to low oil pressure. We had the boat fully loaded with the fam and gear for a weekend over at the island. I had accidentally knocked the throttle to fairly wide open on one of the engines (out of gear). Sure enough, started with a lot of noise, (sounded great) then knock, knock, knock. “Sorry fam, we’re going home”, engine out, strip down etc. Aggggh! 😁 Your new engine sounds sweet. Looking forward to what next year brings. Wishing you and all the fam a great happy and safe Xmas and all the very very best for the new year, Cheers 🍻

GF has 8 skis in her back yard, been sitting 14 years... Might have me a rental company soon hah

Do the Catalina race next yr!

Pretty sweet other than having A V8 directly under your junk. Thankfully rod usually go out the bottom. Backfires Are a different Beast altogether though

fireing order

Can’t wait for the next update! How’s the 1100 superjet doing?? Anything new with that

Now drop that into a sxr1500 if you want to be real cool 😂 sea rat 3 here we come!!😂😂

I want a diesel jetski :)

Do u have any videos out with the gear mechanism what you did in the back

So I got an old Polaris 750SLT with a hole in the middle piston. Any good engine upgrades I can swap in place of the original 3 cylinder?

With max rpm of whqt, 7500 rpm, do you think to hit 100 miles per hour or more, need higher rpm ? Or bigger jet pump, prop ? Or different gear drive ratio ?

Are those exhaust manifolds just car ones or are they water cooled ?

Sounds like it has a mild cam in it

Are you guys planning on a fx1 build in the future?

What's the spec you on the gear you made

Hey Josh, Any update on why the bearing failed ? Did you make some mods on the new engine ?

For the desire to do something, grade -A. For knowledge of the basic laws of physics, dynamics, hydrodynamics -F. There are small turbo jet engines. Good from a tank) but big.

what spark plugs do you use??

How are your neighbours? lol

keep it up bro 👊🏻❤️

Update ?

It's not a rotary engine , it needs push rods😂✌️

jesus i was hoping you lit this thing on fire at this point and just kept honing your skills modding any other skis. i have begun to hate this thing on your behalf. i have a 2017 yamaha gp1800 that's blown up during every break in since I bought it. This is your version of the GP1800 lemon that I own. Have i given up on the ski yet? no. like you i am stupid.

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

god...i bet the neighbors cant stand them....lolol

setting yourself up for failure by not using a torque wrench....thats probably why it failed in the first place and you still havent learned your lesson....😮

Gotta love yourself, gotta hate yourself 🤷
