Cant believe I didn't figure this out sooner.... v8 turbo jetski run in water

[@rfiskillingussoftly6568]

Dont be so hard on yourselve ..I changed the motor in my full sized 1981 Chevy van ...3 mechanics said it was the motor...so I put in a mint 355 sb...the thing still had the blown motor symptoms...IT WAS THE $15 IGNITION SWITCH!!! :))

[@izitwet]

Use a 30a relay from the start switch. the relay will take the higher current that is pitting you contact in the button.

[@JetSkiBrothers]

I think this is what I will do, it seems like the best solution to me 👍

Hope you enjoyed it!

@@JetSkiBrothers You know it. Great video !!

[@Talkitout0]

2:44 hope the kids weren’t napping during this rev up.

[@Scott-ni2gq]

Why do you have a 85mph V8 ski when others do that? Because it’s AWESOME! Seriously I would rather that then anything in the water. The best part when it’s together is when you first start it. It’s a beast! Love the vids!

[@JetSkiBrothers]

This guy gets it 👆💯

[@cpcassone]

That thing sounds like it is going to be quite a handful when it hits boost! Awesome work Josh! You always find a way to keep making things happen! Keep it up brother!

[@JetSkiBrothers]

Thanks 👍

[@unclewill]

I’m wondering if your going to have to upgrade the jet pump to keep up with the horsepower

[@MrSector9]

That is sounding spicy, cannot wait to hear it during some real top deck on tests. Great job on this.

[@JetSkiBrothers]

You and me both!

[@derrickanderson2783]

@7:39 That smile when you did something cool and you know everyone knows it!

[@izitwet]

That thing cracks me up. In his videos last year listening to it run from the camera distance, what it sounds like is something you’re not seeing. It sounds like a full-size lake boat sorta like a jet boat from the 80s. The last thing you think the sound is coming from is the damn sit down. I think you guys have come a long way with this project. One of a kind NO ONE else has attempted anything like that. That’s a good thing. Awesome job!

[@mjethier]

lmfao at that turbo whine. You effin guys are crazy! I love it.

[@JetSkiBrothers]

You know it! 🍻

[@MRR-qv3bw]

Hey buddy you need a relay off your starter switch! That's how they wired from the factory to control the current to the solenoid. If that doesn't fix it then you need to bust out the voltmeter to see whats going on and look for shorts or ground issues!

[@JetSkiBrothers]

Yeah I’m going to add a relay to it for sure

[@charleshorseman55]

It's cool that makeshift welded waterjacket quiets the v8 so much. Very cool! Can't wait to see it hit the water! Maybe tuck some kevlar under that seat for good measure ;)

[@JetSkiBrothers]

Good idea!

[@danw1955]

Man, this thing is going to be nutso when you get the lid back on it, and out on the water! I think 85mph.+ will be a piece of cake now.😮😄👍

[@waynep343]

Go to a truck alternator or starter shop they have the perfect relay to mount at the starter. Dont forget. Marine starters have an additional plate and seal between the armature and starter drive to keep any gasoline vapors in the bilge from exploding when you crank the engine. The bilge blower does not vent the starter housing.

[@youareright5431]

I would consider this a god send because it made you look at the gear box👍👍👍👍

[@thejourneyretold]

Holy shit I know where you guys are! I did some work for your neighbor last year!!! lol Small ass world! Keep up the great work fellas!!!!

[@JoelArseneaultYouTube]

I would have never in a million years guessed that it was the starter button... I mean... it just sends a very low amp 12V "signal" to the relay... Wow. Good to see some successful testing ! It's sounding really good. Looks really promising for a top on test. 🤟

[@JetSkiBrothers]

Yeah it was the last thing I thought it could be. Should have known though because we’ve had so many issues with those Yamaha lanyard switches. The way I finally found it was by checking the signal wire at the starter solenoid and it only had 5 volts. It’s one of the first things I would do if I was diagnosing a bad starter on a car, but for some reason I decided there was no need to check that 🤦‍♂️ it’s a good reminder for me to not overlook the little things

[@epoh8698]

Being a turbo guy was good to see you throw one on, Last vid i watched was you putting it on. So i never new about the starter, That sux anout switch always the simple things first as we learnt on cars and even dirt bikes in the middle of no where lol Good to see you got it tho mate. Its sounding really good. Build that grip strength up haha

[@JetSkiBrothers]

Yeah I am looking forward to riding it 👍

[@stevejohnson8703]

Had that problem with motorcycles before. Sure is quiet now or seems like it, but good to here it running either way. I'm so ready to see it back on the water, as I'm sure you are. Good job

[@JetSkiBrothers]

Yeah it’s quieter than before the turbo acts like a muffler cutting down on the engine exhaust noise. But it still sounds good

[@shawnholiday7386]

90 mph or bust!

[@JetSkiBrothers]

I want to get into triple digits but we got to start with 90+ first and build from there 🍻

[@timlong1462]

@@JetSkiBrotherstriple digits would be wild. Probably consider some purpose build suit or flex seal the crap out of the backside of a wetsuit. Anti enema suit lol

[@user-ej1bq4bq2w]

Dude this thing sounds so incredible! after all the time you've put into it its really good to see it starting up and idle smooth, taking the short throws without issue. That's gotta make ya feel good

[@camyota]

Man I want a jet ski so bad! This thing is awesome!

[@JetSkiBrothers]

👍

[@Kincentc]

I hope you guys are ready. Even a meager 5psi is going to be downright scary. 2x more HP than any production ski.

[@JetSkiBrothers]

I hope it’s pretty fast but we’ll put it to the test and find out. 👍

[@Sonny_McMacsson]

Won't work worth a damn unless the jet pump is matched properly to the power.

[@GoldenCroc]

Corroded switch, huh? Like the TPS? It didnt like salt water bath either or is this more age and bad materials/constrction related, seems like you are saying its a common waverunner fault? Also, Jacob being Jacob is a always a treat. Never change, Jacob.

[@JetSkiBrothers]

It’s not salt corrosion it’s more carbon fouling probably because it’s not designed to flow that much amperage

[@GoldenCroc]

@@JetSkiBrothers Ah, so bad construction then. Got it. Keep up the good work!

[@Pathfinderxr]

Strange. It looks like a roller bearing rather than a thrust bearing.

[@clintonbeasy6609]

This is insane i love it awesome brother

[@madnessmaker6162]

cool project! maybe a slip a a/w intercooler in there. at some point and turn it up. :)

[@JetSkiBrothers]

Possibly!

[@yelyab1]

There has to be some theoretical limit on how fast you can pump water through a vane type pump before it comes out the exhaust as live steam. Not sure if that gives the same, equal, or more thrust. I think the pump would blow up just before the pressure and temperature required for steam is reached. We won’t know until we have the data, so do it.

[@sneezinhatch]

There is a 400+ hp v8 ski that can go over 100 mpg with mild tuning

[@nickk5368]

A lot of that is in the pump he’s got plenty of power the pump is gonna limit him here

[@dirkdiggler4860]

Awesome!

[@kkbodyshop]

Heck yeah !!!

[@nicolashuffman4312]

I bet that thing is going to do 35mph at idle!

[@JetSkiBrothers]

It shouldn’t go any faster at idle then it did when it was naturally aspirated, and na it was faster then a normal jet ski at idle but not too much. But yeah I get what you’re saying

[@holdenbrougham1056]

Agree with others put a 30 amp relay on the starter or near it

[@garyhorton9280]

Awesome

[@race2race1]

That should be pretty quick but it would be real fast if you could get rid of the jet pump and convert it to a V-drive.

[@JetSkiBrothers]

True, jet drive soaks up a ton of horsepower

[@julioramirez3345]

Hi, I'm from Puerto Rico but I've lived in the USA for 23 years and I don't miss your posts. Ask what size Nozze do you have on?

I have a 2016 fzs. Should I look forward to the bad start stop switch? 182 hours on it. Stock but runs great!

Not necessarily, they might have the updated version on the 2016 and this one is a 2009 with around 400 hours on it.
