We Run 90MPH on 93 Octane PUMP GAS on a 2021 Yamaha GP1800R SVHO: The Watercraft Journal, Ep. 135

Wanna go fast - and we mean REALLY fast - without re-engineering an entire jet ski? We test ride Greg Gaddis of Greenhulk Garage's insane 92mph 2021 Yamaha GP1800R SVHO. While conditions weren't optimal, we clicked off an incredible 90mph at 9,150rpm (making 20lbs. of boost) all while burning pump gas 93 octane. You gotta see it to believe it.

Great content. Love to see Hulk Jr getting out in the world. Nothing like backing up his amazing mechanical skills & letting others ride the beast! Great job Greg, we all appreciate you guys taking the time out to make this all come together. And wow an added bonus to have Josh from Watercraft Zone in the house! PS: So freaking jealous Kevin Thanks again, Billy D

[@jasonmekush5280]

I am def a happy repeat customer of 4tecperformance/ greenhulk and watercraft journal for merch. top notch companies. i bought my blue 21 about the same time as Greg, went as far as stopping b4 intercooler and retainers. hitting 85 on dash w 2 ppl and a full tank of gas fl heat 94 degrees.

Stuck like glue... well done!!

Amazing just hit 80mph on my 23 gp1800svho 💪

[@markadler8968]

I can only imagine the numbers you will be able to get with the new 1900 engine coming out.

[@F1FIDY]

There is no 1900 update for the SVHO , it stays for now the supercharger 1.8

[@terpsquirter7107]

@@F1FIDYthat’s incorrect the 1.9l doesn’t come on any of the new svhos but to add a supercharger it’s literally the removal of a metal plate and gasket bolts on in exact same place as the 1.8 as well

[@F1FIDY]

@@terpsquirter7107 i’m not incorrect at all the supercharger will not mount up the 1.9 does not have anywhere for the supercharger clutch don’t debate about something you have no information on.

[@terpsquirter7107]

@@F1FIDY yeah that’s literally where your wrong the 1.9s mounting point for a supercharger is in the exact same place as the 1.8l only covered with a plate u actually think they redesigned the entire 1.8l engine it’s the same fuckin motor bored over u mong

[@terpsquirter7107]

@@F1FIDY you want to know the overall differences it’s literally like 4 things larger bore, optimized intake and exhaust paths, a 10% larger throttle body and a redesigned intake manifold the only thing new on this engine so maybe know your shit for you go tellin people to not speak on shit they don’t know 😂 lmfao

[@mahall75]

Very Dope!

[@chasefalgout9467]

Wow, Yamahas are pretty impressive for tuning

[@edwardbowles8613]

Amazing and scary fast. Sorry if I missed it but I assume acceleration suffers a good bit? Built for top end only?

[@prodajaveshey731]

Kevin what are you thoughts on the Riva Pro Steering? How did it compare to a stock GP Steering for you?

[@mannylopez3959]

It’s so easy to make power and work on this ski. I got mine because of him 😅 Sponsons definitely a must as it settle’s it down

Did anyone happen to see what the GPM of Fuel Consumption was on the Trip/Fuel Info Screen of the Factory Dashboard??

[@sq07rf]

What cart does he have the ski resting on? Looking for something similar so I can work on some clear coat scratches from the trailer bunks underneath. I have the 2023 gp.

[@watercraftjournal]

It's a custom aluminum cart that I snagged from America's Motor Sports in Madison, TN

[@ericsmith6677]

does anyone know if anyone makes after-market super chargers for Jet skis? ive been a car guy my whole life so im still learning marine engine applications.

[@cts-vme3353]

No need ,they sell different SC wheels

[@paullinkins8121]

9350 RPM! I can't imagine how often the engine needs a rebuild if pushed that hard very often. And with 1.3 G of acceleration it'll probably outdo the 1500SXR in 0-30 MPH -- which is arm-ripping stuff.

[@terpsquirter7107]

He’s yet to rebuild it did you not listen to the video he has 150 hrs on the motor

[@d4nnyq1976]

Can you tell me if the ski has mirrors delete?

[@watercraftjournal]

Do you see mirrors on it?

Why does nobody run e85?

I have the same ski, great ski & not babied also, have video same ski going 90mph in choppy water with full tank gas.

Dang Kevin you’re only 10lbs heavier and 2 years older then Greg so 92 could of been possible. Looked like good fun.

I’m 23 years older and 90lbs heavier than Greg.

[@tiredofthetyranny9874]

How much did it actually cost to get there? IF someone did it their self. Not paid a shop for everything!

[@tiredofthetyranny9874]

Nevermind seen the text on screen at 14:00

[@alhit007]

Great that you can tune it on the go but I find some “gauze pads and 3 in 1 oil” are your only man, specially if you decrease the main tank to allow for more weight and then increase the pressure to blow more with a return valve connected to the rotor spinning up and out so to bring the power curve to a more steady flow henceforth the main reactor will produce more power,,simple , never fails…

[@watercraftjournal]

Nobody knows what the heck you're trying to say.

[@alhit007]

@@watercraftjournal it’s simple really, as Chevy Chase said “Gauze pad and three in one oil” sorts most problems out, but really great interview as usual Kevin and only yanking your chain, it’s an Irish thing, Loved your coverage of the new launch’s from Seadoo’s range!

Invest in a better camera. Your content and editing are good but the 1080p is over 10 years old now. A 55" 4K TV is less than $250 now and everyone has them so that level of video quality is expected. People only have so much time to watch YT vids and with so many content creators trying to find subs, vid and audio quality matters, IMO.
