It was nice to see the 3 of you in this video. Much respect to Joel for really putting in the hours to complete the exhaust. This build is getting close and I'm sure you'll on the water soon.
Guys guys guys!! Coming from someone that builds aluminum boats pretty much every single day. Use a jigsaw to cut the aluminum plate. It works so much better then a grinder. And it’s much more accurate. Bandsaw works the best. But not everyone has a bandsaw. Looking really good!!
You guys are like the Wayne and Garth of the v8 jetski world. Great work guys. You remind me of me back in the 70s and 80s when I was jetskiing. I wish I were back in my 20s to do the stuff you're doing. I started out on a 1976 JS400 I bought brand new in 1976.
Are you guys not putting rubber in the mix for the motor mounts? I would think doing solid aluminum like that with no rubber isolators would vibrate that thing to pieces
they did , only shown for a moment but they're using the stock jet ski mounts into their original location, but additional mounts are in the works. I assume more jet ski mounts.
Of course I was playing off that joke about daily validation 🤣 you guys have some amazing content and some even more amazing fabrication/machining skills. Keep it going!
when you turbo it and making sweet turbo noises and sounding like a freaking jet engine you could call it the jetski but with the emphasis on the JET so that the haters can hate
Joel I have a question. Well actually 2. If the primaries are not water cooled what will keep them from melting under a load? Aluminum melts at 1221 degrees F. Exhaust gas can easily reach that temperature under a hard load. Also if the primaries are exposed and not cooled in a pretty much enclosed area, won't that cause it to heat up the inside of the ski like a oven? Not trying to bash. I just want to make sure it will work awesome and maybe bring up a possible problem that might be overlooked.
@@chrisglassey8585 Thanks for the comment, Chris ! That is observant and a real concern. I have plans to help deal with overheating, both to keep the hull from burning and to keep the primaries from melting. To ease your mind a little, I will write a little more detail. You may already know this, but one of the reasons that they use aluminum as pistons is that it is able to dissipate heat very quickly. They used to be made of iron and people thought aluminum would melt, turns out that it transfers heat to the cylinder walls so well that it works better than iron, despite the combustion chamber temp being around 4500F One reason I made the flange out of 1/2" bar stock is so that it is able to absorb a lot of heat from the runners, I will also be suggesting that the JSB run this without a gasket, just some glue, so that the exhaust flange is able to transfer heat to the head. Also, the primary runners are attached to the log that will be kept under 100C 230F by water cooling. The runners should be able to transfer heat very quickly because of this. I don't have all the details worked out, but I am going to be cooling the runners, they just won't be fully jacketed as there simply isn't room. Cheers.
@@JoelArseneaultRUclips Yes the pistons are also cooled by engine oil under them and the fuel and air coming in the cylinder. Well hopefully it will work man. Good luck to ya man.
@@chrisglassey8585 That is true, however, pistons have the huge disadvantage of not being in direct contact with anything except for the wrist pin bearing. Most piston cooling is done through the rings and sides of the piston to the cylinder wall. Oil, fuel and air are very much secondary. (in most engines) The runners are going to be part of the flange and part of the log. Heat transfer in this way is much more efficient and the temperature differential will be massive, making the transfer work even more efficiently. Bottom line is that there simply isn't room for jacketed runners, they may touch the hull as is. It's all a giant experiment. I have a LOT more questions or curiosities than I have answers :)
Jason is the Martin Scorsese of the jet ski world🤣🤣 I've learned so so much over the years. Also don't worry about your toes using that cut off tool in your sandals🏨🏨😆. Who needs pinky toes anyways. Seriously though Joe is doing a great job on the intake manifolds can't wait to see them completed. Carry on men.
and if you go above 68 MPH with this hull it will pump stuff on you. had mine do it a couple times. just about snapped my wrist the last time it did it. the fix is an intake grate with a top loader wing into it. i got a worx one i think from greenhulk
Much needed update and progress report guys .. We needed hit of content for a while now , been jonesing ... Current feedback with your chanel patrons is great community activism. Shout out style in video replies are well received and fun. Are you keeping track of the build cost tally? Any ideas on a completion date or top speed ? please oh please let there be a Thursday video. once a week keeps me hungry for more. Hope to see you soon.
Small tip for you guys: Stop using a grinder with a steel wheel to cut aluminum. You should invest in an aluminum blade like the Oshlun SBNF-065060 6-1/2-Inch 60 Tooth TCG . It works really good.
21:30 I couldn't help but stare at the sticker on the bodywork that proclaims that it is a jetski while you are reading the comment by someone saying that it is not a jetski.
love the build boys!! awesome work! use a candle... cut into a candle/ swipe candle on edges of disc while its spinning... with cutting discs before cutting aluminium works a treat! 👌 ya discs last longer too!
@@jasonskibrothers2192 definitely not joking boys.... my grandfather builds planes, gyrocopters and anything else made of steel, alloy, chrome molly... anything... I started tig welding alloy and steel 2years ago and his taught me everything so far.. even the candle on the cutting disc for alloy trick haha so thought I'd share with you guys considering lots of alloy cut lol

Saran wrap, Scotch tape, Sharpie markers, Kleenex tissues... For people like that I have this to say. The purpose of language / speech, is to convey ideas... You are the one pointing out that it is a Yamaha Waverunner that is being described.... so by using the words "Jet Ski" you got an accurate representation of the idea intended to be conveyed... By pointing out that this is "wrong" the only thing you are really pointing out is that you clearly understood what was meant and that you like making a fuss about nothing. See... language is complex, poetic and colorful... like if I said you were a dick head, in a literal sense that's of course wrong, but also surprisingly accurate.
I have mastered cutting and machining aluminum and I am trying to figure out how to make some money from my years of figuring out easy ways to deal with aluminum.
Jason , I appreciate the literary injection , but they must be sprinkled in slowly, over a medium heat. I always knew that you had a bit of Jame May to you . Refined and calculated, yet whimsical contributions never get old. Glad to see that your broken foot has healed and is presenting itself , exposed for more potentially perilous predicaments . Please put protection on you pedestrian peddle pushing p p pheet .

I'm excited and enjoyed the first 6 min 20 seconds. The rest. Not so much. Enjoy footage of the design, build and some chatter. let's see how it works and holds up, before naming it.
call it the ls ss 2024. because at this rate it will be lucky to get done by then. for F’s sake, pull some night shifts, we need to see this thing run!!!
Exhaust : Y pipe to single exit exhaust and don’t do ugly long tube headers do single cylinder collectors fingering in to the exhaust manifold outlet tuck it tight with water box
Guys I like the build but if I wanted to read your comments I would go to the comment section my self and read them. Stick to the build I don't care what other peoples opinions on it are.
i just want to sit and talk shit about this stuff with people. Anyone got an extra hull?? I've got a limited run '68 Camaro motor that would be sweet if nothing else lol. Apparently everything else has been done now
You need to start working on a system of bolts to hold the top half of the hull down it needs to be removable you will never be able to bond the two half’s together again... maybe wing nuts and epoxy nuts into the back half... just my opinion
Man, really? This is gonna fuck up your corn field guys.... But worst case I guess, you can sell it to Chevy for a few more years. Look at the 2000's. It was like their engineers had a "put a Vette engine in it" rubber stamp.
It was nice to see the 3 of you in this video. Much respect to Joel for really putting in the hours to complete the exhaust. This build is getting close and I'm sure you'll on the water soon.

@@rickems8863, I thought it just looked like they just used those as a template for getting the aluminum brackets traced and cut
@@philmadden8027 I watched again, it appears that you're correct, solid mount. ...
Your bolt idea is correct I've reused head bolts, flywheel bolts all them . Just have to torque them differently
Get a cheap plasma cutter, it will cut aluminum easily. I got mine on Amazon and it’s great
Of course I was playing off that joke about daily validation 🤣 you guys have some amazing content and some even more amazing fabrication/machining skills. Keep it going!
Oh thank goodness. If you were joking about the validation than I would not get the validation and be paralyzed by the invalidation.
when you turbo it and making sweet turbo noises and sounding like a freaking jet engine you could call it the jetski but with the emphasis on the JET so that the haters can hate

Love to guy cutting the aluminum in flip flops. Finally someone that works dressed like me

Hey guys from Queensland Australia..love your channel guys keep up the good work .
Looks like you guys on top of all the issues and problems that show up during a build of this sort. You should name it Rumble Ski
Are you rubber mounting the engine ? Bolted solid it will vibrate itself to pieces !
it has the stock ski motor mounts
That dude is going to be STUFFED with so many wires, lines, and tanks.
Yes, "War Pig" should be the name.

I use my wood carbide tooth miter saw or chop saw to cut aluminum as much as possible. Angle grinder, gotta use a lot of wax.
Cordless Circular saw and aluminum blade make easy work of that 😉 I do it all day every day 48t or better finish blade will do too
