[@ooleelfive0894]

When we raced stock jet ski with all the add-on’s/ after market, we noticed without the rev limiter and then you hit the right wave and pop it up and out to pitch up the engine, you’ll get more out of it. We called it, feeding it, Scooby snacks past the limit, as we had removed the limiter, you still need to go beyond that limit you had to get it to jump out pitch up………. Last this was with 2 stroke engine but also help our4 stroke Honda turbo so both. Fun times!!!!!!

[@joswelcaruana3082]

link for the 14/19 impeller please?

[@flacjacket]

So 80 mph at 8,200, and this thing should be able to do 9,500 without even pulling the valve cover, that means 93 mph stage 1 or 2, just impeller, tune, and maybe fuelling. Insanity. Now we just need someone at BRP to leak the encryption.

[@GreenHulkGarage]

Well, I will be pulling the valve cover before spinning 9500 RPM. I do not want to be the test dummy for the new valve springs.

These new skis are awesome! You have more nerve than I do because I couldn't see myself modding a completely new ski with a warranty. I can't wait until 2-3 years from now when I can pick up one of these used and tinker with it myself without fear. Plus, by that point there will have been tuners who will have blown up their engines and taught us what not to do without the expense of figuring it out ourselves.

[@GreenHulkGarage]

I often joke that “I am the warranty!” If the ski breaks, I’ll have it fixed and back on the water long before the dealer could even get to it.

[@TheVonMatrices]

​@@GreenHulkGarageI can absolutely understand that argument and that's also why I do my own maintenance. I just wish that mechanics weren't so overloaded and slow so that I wasn't forced to do the work myself when I didn't want to.

[@alvaroperez7879]

This is in great conditions 65 degrees out. With a relatively lightweight rider. So on a warm day with a slightly heavier rider these will still do 76-77 all day which is good!

[@pixy6822]

We do love the supercharged 3 cylinder don’t we boys

[@dreknotz1996]

Great Video. Would you mind making a video to breakdown acceleration #s? Data from the various props would help. Once you go Fueltech ECU, that could also make another video. Just an idea for content. Keep up the great work.

[@seethingsclearlyawaken3424]

Very nice fine tuning. Yeah, 80mph is quite fast for a stock Sea-Doo.

[@Mike-Rxtx]

The community always appreciates these comparison videos with the details of each thing you change and tested results so thank you very much. It would have been great for you to have done the exact same format as you did for the 21rxpx vs gp video with the draggy and the time splits. The modded potential of the new machines is where the fun is at, but always curious to see how a stock 21 rxpx would compare to the 24 rxpx or even an 8500 tune 21 rxpx vs a gps limiter removal 24 rxpx. I would guess harder acceleration on the tuned 21 tho

[@GreenHulkGarage]

If I had a stock 21 PX or even a Stage 1 then I would absolutely do it. The GP is not even close to a fair comparison to this ski…mod for mod this one will be much faster. The 325 is an incredible machine.

[@dreknotz1996]

A stage 1+ FX SVHO is ~1.5 mph faster than a speedunlocked 325 RXTX. A GP would surely give a 325 Seadoo a solid run, a GP goes 80mph with a tune only!! Why are we freaking about a Seadoo accomplishing a similar feat after all these years with soo much modifications? Bare in mind, a 325 from factory already has (stage 2 like) modifications ; upgraded intake, retainers, springs, cam (NA cam with more lift), rideplate and prop. I only think it would be fair to allow a GP/FX the same aftermarket mods for true equal comparison. Otherwise it's all hearsay without evidence A future draggy/speed comparison video would feed the fans and PWC community a major talking piece. Just a thought, Give it a shot champ. Thanks for all yall do.

[@GreenHulkGarage]

A Stage 1+ FX is only 78 MPH. The 325 is over 80 with just the speed limiter removed. The 325 also has an upgraded supercharger making a lot more boost than the 300 supercharger. Just tuning this ski should be mid 80s (5 ish mph faster than a tune only GP). Not saying that it’s not worth doing a comparison, but no Yamaha will be even close to a 325 unless it is heavily modified.

[@dreknotz1996]

@GreenHulkGarage I too thought the same. However, reality and evidence prevailed, we are surprised as to the result up here in GA. Have a view for yourself if you have a second please. A bud and I have ran some ("24 325 Sea-Doo RXT-X w/SCOM Vs 23 Yamaha FX SVHO stage 1+" ) drag runs that are up on KZbin. All mods being equal for both a Yamaha ( less cams and reatiners) and Seadoo, running the same RPM. There is still a fight coming from the 14 year old engine. Don't give up on us Yamaha folks just yet lol. The evidence is out there.

[@stevenalbritton1044]

How do you add pitch to an impeller?

[@richardjackson1745]

Great video... what do you think of the RXT-X 325 vs the FX SVHO. Mostly flat water riding (lake) and more of a cruiser with multiple riders. I love the Yammy reliability but torn between the 2 ca.hoices. Currently have 18' RTX 300 and Yam GP1800R so deciding between another RTX or going all Yamaha.

[@chickenhawk212]

Heck yes man, thanks for sharing your work! Did you pitch the stock impeller to 14/20 as well? How did the hookup and midrange of the the stocker compare to the solas? Thanks, keep killing it!

[@GreenHulkGarage]

The pitch on the stock impeller vs a solas is not comparable because they have different numbers of blades and different blade designs. The acceleration is very close and I could not tell a difference.

[@dreknotz1996]

Data to show the various props would be great.

[@marinejunkies9625]

What did you pitch the stock impeller to?

[@hiennguyen-eg6yx]

Hi Greg love watching here down under in Australia 🇦🇺 My rxtx 325 has 15 hours now I still cannot get more than 124 kph or 77.05 mph at 8250 rpm.. even with the maptuner scom stuck at 8250 rpm and 77.05 mph.. I'm 100 kilograms or 230 pounds , is this the reason I can't get that extra 4mph. ?? My mate from the maptuner shop here in Sydney Australia says my ride plate is a slow ride plate, and even after trying 2 maptuner scoms no better result.. would your impeller help me gain this extra mph, would love to here your opinion Greg ??? My mates and myself love ya vids mate cheers 🍻

[@GreenHulkGarage]

If you’re turning 8250 RPM then you’re on the rev limiter and losing speed. You either need to add pitch to your factory impeller or buy a solas impeller.

[@PatrickQuain-no2ve]

Seems like the real key to the best performance is adding pitch to these impellers! How does the average joe accomplish this??

[@GreenHulkGarage]

It’s easily done yourself following these instructions on the GreenHulk Forum www.greenhulk.net/forum/personal-watercraft-performance-skis/sea-doo-pwc-performance/sea-doo-how-to-faqs/2743-impeller-pitching-updated

[@skierman64]

Isn't the dash speedometer a GPS speedometer? Why would it be inaccurate?

[@Briandswinford]

Cool stuff. I heard the PX impeller is different from the TX impeller. Calas already did the comparison between the 2 and suggested us TX riders get the PX impeller. So this might be an option for us TX owners to get the PX impeller and repitch it. This would be perfect for my needs, low 80's on an otherwise stock ski. What can you say.

[@GreenHulkGarage]

That’s correct. The PX impeller is very good.

[@jimny1111]

Thats true for 300s. 325s share the same props....

How does the RXP-X 325 compare to the GP1800R SVHO in regards to handling?

[@GreenHulkGarage]

If you’re capable of making your own harness then that will be a much cheaper option. The FuelTech PNP harness is top notch and worth every penny. It’ll save you a lot of time going with their PNP harness. I currently do not have it in stock but I will as soon as it comes off back order.

[@petermieszczanski8591]

Just wondering as I have come across this today, on a 2005 seadoo rxp, should a new jet pump bearing have some very slight side to side play? Bought a WSM jet pump rebuild kit and noticed this while installing. I have read the service manual and according to seadoo there should be no play in the shaft or bearing. On my 2017 rxt-x that I am rebuilding the jetpump on, I noticed that there was no play in any direction and is very tight compared to the 2005, is this normal?

[@GreenHulkGarage]

There should be zero play! The Chinese copy parts are crap! Only use OEM!

Thanks for all of your videos! Just ordered riva stage 1 with 14/19 for rxtx 325..kinda scared to swap impeller after seeing a lot of older videos of Solas exploding. Do you think they're safer or have worked out the issues? Thanks again, appreciate everything!!

[@petermieszczanski8591]

its quite suprising how many complaints there are on the solas impellers even from the 300-215, a lot of people say they either don't see any improvements or actually a diminish in performance from using a solas. most of the time they recommend just using the rxp-x impellers as they normally are quicker response. Almost looks like solas is a budget friendly alternative they are around 10% cheaper than OEM seadoo impellers.

[@GreenHulkGarage]

Most of the impellers you hear about coming apart are the fake Chinese copies. Be sure to use a genuine Solas impeller and you will be fine. Glad you enjoy our videos 😁

Nobody knows. This ECU has been on the market for many years and nobody has been able to crack it.

I am curious about the supposed "Horsepower War" that people have said is coming. As a Kawasaki fan, I hope they graduate from the 1.5L and maybe go to a 2L. The only thing keeping me from Yamaha is that annoying visibility spout. I realize it’s super easy to disable but the fact there’s this hole in your deck mat for the damn thing bothers me. Anyways good video as always

[@GreenHulkGarage]

I’d love to see a horsepower war but I don’t want to get my hopes up. I’m hoping that Yamaha has something for 2025. Only time will tell.

[@TheVonMatrices]

There's only so much displacement you can have while still being able to fit the engine in the hull. I suspect that the primary reason Sea Doo has stayed with 3 cylinders is because it keeps the engine short and allows them to have the narrow, "ergonomic" seat. Yamaha can never have a narrow seat that with the 1.8L engine being as big as it is.
