Sea-Doo RXP-X 325 TOP SPEED with Speed Limiter Removed 

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.

I understand completely why you dont want to be the test dummy, but the community desperately needs one 😂​@@GreenHulkGarage

Will any of these mods void the warranty?

@@spacklerat3214yes all of them😂

I don’t wanna go this month, the waters too cold

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.

Good suggestion. I’ll keep that in mind for future videos.

@@GreenHulkGarage

I love doing it. Can’t wait for you to finally be able to ride it!

@@GreenHulkGarage Me neither Greg

We are at sea level

They are very different. I prefer the GP for all around riding and rough water but the RXP-X carves a turn like a dream. The GP can keep up with it around buoys, but you really have to work for it!

@@GreenHulkGarage You keep selling me on the Sea Doo, and I just bought some sponsons for my GP from you guys, lol 😂

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.

Data to show the various props would be great.

What did you pitch the stock impeller to?

No.

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

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.

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.

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.

@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 RU-vid. 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.

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.

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

They are speed limited to 68 mph

@@GreenHulkGarage Damn, that's low for a bad-ass ski.

I can promise you, it will be faster than that. I have a few tricks up my sleeve. 👍

The impeller was 1 mph faster.

Nobody knows. This ECU has been on the market for many years and nobody has been able to crack it. Right now the only alternatives are to remove the speed limiter with the Riva service, linked here, or to go with a stand alone ignition such as FuelTech www.4-tecperformance.com/index.php?main_page=product_info&cPath=544&products_id=16017

The ride plate is perfect. Definitely not a slow plate.

​@GreenHulkGarage so it has the long taper per riva data?

So you’re going to cross over to the dark side and get rid of that Yamaha? Lol!

@@GreenHulkGarage lol no ill keep both and add a seadoi. i used to race for tgem in 97. gp is edge of good reliability -84 mph. fzs 81 w 2 gas cans on back.

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.

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.

@@TheVonMatrices fair

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

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

@@jimny1111 Thanks for the info. I never thought they would have done that, but I guess that makes sense .

Yeah it probably acts a parachute! 😂 They perform extremely well from a dead stop. Zero cavitation!

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.

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 😁

@@petermieszczanski8591check and set slip at 200 hours and fully rebuild it at 300-350 hours depending on how hard the ski was ridden.

@@GreenHulkGarage Awesome, thank you!!

@@petermieszczanski8591 yeah that's what scares me although all the main guys or reputable companies are using them which makes me feel better.

Speed limited to 65mph

It does not.

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.

​@@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.
