Now we need this same shoutout but between the two 3 seaters most popular the Sea Doo RXT-X platform vs the Yamaha FX SVHO 3 seater. This shoutout should be epic I can’t wait. Come on let’s make it happen, 👍💪😊
Back in Dec. 2016 I got a great deal in AL (no sales tax!) on my white/green 2016 FZS SVHO. I removed all of the factory "Yamaha" and "scare" decals. . I didn't want a "new" 2017 GP. The FZS is so much more "sedate" looking. It is now a forgotten "sleeper" at somewhere over 80 mph thanks to "Jim". It has all of the entry level mods. And the sleeper look is what I wanted .Much more fun that way! With no rear "spout". most guys think that it's a Kawie. I keep it in pristine condition and have no plans to get rid of it. Instead I prefer to upgrade. Anything new on those with no SC upgrades (yet)? Probably not.
I thought the GP would walk the PX mod'd.. I have a SCOM'd RXTX and my buddies with heavy mod GPs tell me that all the time.. turns out its alot closer than I (or most people) thought. Cool!
Ur comparing a seadoo that is already tuned from factory making 300hp to a restricted gp making 250hp. You wanna see true results is to have both units at same hp
My dealer sells Yamaha and Seadoo, I was a seadoo owner but when I asked what I should buy for a 2021 they said GP1800R SVHO. Reason, they said look in the shop. I’ll take a little cavitation if the trade off is early engine replacement so now I’m a happy SVHO owner
Great to see a shootout with the same mods , you have a vid and specs coming with some more rpm on the px ? Any one done a shoot out between the tx and px - same running gear , but a great way to compare the impact of hull design
I believe both 13/18 impellers are 3 blades - looks like a 4 blade is shown in the video...mind sharing what adjustments you made on the 13/18 on the seadoo? And what top speed rpm you were running with the adjustments on a 8500 tune?
@@GreenHulkGarage I am running the same tune riva stage 2 8500. Last summer I was in target range of 8300. Currently I am spinning 8500 rpm. I live in Canada so there is a significant difference in temperatures 30•C to my current 10°C. But over winter I did upgrade to a better aftermarket intake with a velocity stack and upgraded ic pipes. So right now I can't tell if the rpm is from my parts or from the weather or maybe both. I am unsure if I need to repitch (again) my stock impeller to bring down my rpms or just wait for hot weather to come back and see where I am at. My understanding is 8500 rpm is safe on stock engine internals however I must be hitting the rev limiter currently. Another thing that's odd is my top speed has stayed the same even with the extra rpms? I would appreciate your thoughts on this
@@Mike-Rxtx in your cooler climate, you are no doubt on the rev limiter. Instead of depitching your impeller, I highly recommend installing the Lucky 13 adjustable pump cone. This will get you off the limiter and add some performance. The reason your top speed stayed the same is because your engine is running on the limiter. This is the Lucky 13 adjustable cone that you need www.4-tecperformance.com/index.php?main_page=product_info&cPath=350_207_210&products_id=2355
@5:13 I'm a Yamahaw fanboy. I made my purchase choice on quality and longevity. Performance wasn't a concern as they are so closely matched. SeaPoo fans can still say they have the horsepower and better 0-40 times. However, from the times in this video it can been seen that Yamahaw has the better 0-60 times because it produces its boost and max power above 7500rpm and takes time to get up to that rev range. I wonder why Yamahaw does this?. Has anyone changed to a supercharger impeller that produces boost at lower rpms?
The reason seadoo has a better 0-40 time is because the seadoo has a better holeshot. The Yamaha cavitates badly on holeshot which is slowing down the acceleration across the board. If we look at the 20-60 time of both the Yamaha and seadoo to eliminate cavitation, the Yamaha is much quicker

I'm so far away from this result. And everybody says it's the Heat. And I'm running with less than a half a tank of gas probably the best we've seen so far is about 75 mph GPS
I love what your doing man ! It also really helps me to chose my next ski ;) I was just wondering, someone told me that with the MaptunerX, we had to change the yamaha's compressor freewheel every 20 hours, do you know something about it ? That's the only reason I still haven't done it on my 2019 SVHO ... It has now 135 hours and i'll certainly sell it for a 2022 RXT-X or a 2022 GP1800R SVHO but the european model doesn't exist with factory installed audio Kit so I don't know ... Are the stage 1 kits in the description only for US or can you ship it to France ? I'm french by the way, sorry if my comment contains mistakes :)
The problem with a drag race is it doesn’t truly show which one is faster. Yeah it’ll look cool, but it isn’t an accurate. Differences in rider weights, difference in rider skill, and it is impossible for both to leave at the exact same time.
answer is at 1:25...Both have Riva Racing powerfilter kits, the SeaDoo has a catch can and the Yamaha has the Riva Racing engine breather equivalent, both have SOLAS 13/18 impellers. The SeaDoo has the MaptunerX Stage 2 8500 tune and the Yamaha has the MaptunerX Stage 1+ 8500 AGR tune. The SeaDoo also has a stainless steel wear ring.
I hate cavitation, like it drives me nuts. Id rather take off smooth with a seadoo then be bouncing up and down out if the hole on a yamie. Why cant they get it right? Ill stick with my 21 PX thank you Like how many GP owners are going to do a stage 2 or 3 and also what ever they need to spend to get the cavitation issues fixed.... waste of money
The Yamaha will only increase its top speed difference over the Seadoo as the stage goes up, especially after the new ride plate is out on and hole shot improved.
I bought 2021 rxpx 300 2 months ago. Already put 65 hours on it. I compared it to gp1800r and in my opinion rxpx is a better built watercraft. Sound system, turning is better. For some reason Yamaha all plastic seems cheap and shakes everything on fast speeds. Yes Yamaha is more reliable as far as engine but they are very cheaply built. Same with Kawasaki

I was out on a new Yamaha 255 supercharged boat, and it cavitates stock! Its like adding power on a car but not upgrading the tires!
You need to install a Lucky 13 adjustable cone. It solves the cavitation issue on the Yamaha boats.
Great video, excited to see that hole shot upgrade for the Yamaha and that one is going to fly!!
Me too!
@@GreenHulkGarage question have u still fixed the hole shot?
Great video. Good to see these two at the same RPM for testing. The GP is more user friendly in the chop too
Awesome videos! I’m in South MS! We will be on Pontchartrain this summer on my RXP! I’m “Cagedup” on GH. About to start the mods!
Good stuff I guess my 2019 doing 80 / 81 is now acceptable 👍🏻👍🏻

I’m getting ready to do a video on the PX with RPM right at 9000. No one I know of has done a video on the PX vs TX
Rather than repitching the 13/18, will you start using the new 13/15 4 blade in the RXP kit?
Yes. My impeller is already on the way and comparisons will be done back to back with the stock impeller, out the box 13/18, and the new 4 blade
