So many of you have been screaming for a throwdown shootout, so we've brought you the two most exciting personal watercraft in the marketplace today, the 2018 Yamaha GP1800 WaveRunner and the new 2018 Sea-Doo RXT-X 300. Because handling tests can be subjective and drag races are almost never foolproof, we devised the ultimate test: an acceleration showdown using two bone-stock skis with nearly 30 hours on each clock (28.9 hrs. on the Yamaha and 33 hrs on the Sea-Doo), fully-topped off tanks (so that there's no question how much fuel was in each ski), and the same rider (Greenhulk.net's own Jerry Gaddis, weighing 235lbs.). We use the a Vbox Sport (one of the most reliable accelerometers available) to track true 5-to-20, 30, 40, 50, and 60mph, as well as sustained (not peak) top speed. You won't believe the results because neither did Jerry or we.

Question. I own a 2018 sea Doo GTR230. I am looking to buy either a GP1800r or a Sea Doo RXTX 300. I ride mostly on the river and lake. The river can get choppy from time to time. My wife wants the GTR and we have two kids. Which on should I get? Thank you for your help!
Watercraft Journal thank you for all your insight. I still am not sure which one I’ll enjoy the longest. If you were in my place, which one would you invest in for long term ownership since I already have the GTR230? Plus I tend to ride is rough water.also, I am 6’4 225.
6 one hundredths of a second(just over half a tenth of a second) difference for the 5-60mph run, that's basically a draw. More telling is the roughly 2 tenth or 20 one-hundredths of a second advantage for the Seadoo for the 5-20/5-30/5-40 and 5-50mph runs. For the Yamaha to be down by twenty-hundredths during 5-50mph acceleration runs, and then decrease that disadvantage down to only six hundredths when accelerating from 50 to 60mph, tells me that the 50-60mph acceleration is superior in the Yamaha. It would be a great test to take the limiters off of both machines and then test their acceleration runs AND their top speeds. I remember the days in the late 90's when I had a brand ndew Yamaha GP1200 2 stroke triple cylinder rated at 135hp-58.8mph on the Stalker RADAR gun-bone stock. My buddies 1994 650cc SeaDooXP was always on a towline, another friends SeaDooHX wasnt much better(his blew up and eventually he had to replace it with another HX) nor another friends 130hp GSX Limited. I had every single one of them on a tow strap behind my GP1200. The guy I shared a double trailer with had a 1998 Waveblaster 2 90hp 760 twin never had issues. I never had issues on my GP1200, and other friends of mine had a few single carb 63 hp and dual carb 73hp Waveblaster 1's had great reliability. Bambardier (Seadoo) just had really bad reliability back then. It was all my friends horror shows with machine reliability would never let myself buy a Seadoo machine, even today. The ONLY time my GP1200 gave me an issue is the one time that I forgot to install the drain plugs and I flooded the machine. I got the water out, pulled the sparkplugs, turned over the engine to blow the water out, reinstalled plugs, snapped the ignition wires back on, cranked her over and she started right up. I so wish that these newer machines like the GP1800 were a couple/few hundred pounds lighter. A machine weighing around 1000pounds fully fueled it too much for a two person musclecraft IMO.
I do, and it was for less than a year. Yamaha was on top of the issue big time. And except for heavily modified machines or dudes who kicked up $#%&storms online, Yamaha was very good about working with the owner and the dealer to try to warranty the engines. I am personally aware of nearly a dozen instances when Yamaha warrantied the engine.
Hours on the engine matter for a multitude of reasons, the two most prevalent being:
1. Both Yamaha and Sea-Doo restrict the engine's ability to reach wide-open-throttle (WOT) and maximum RPMs until 8-to-10 hours. It's commonly referred to as "unlocking".
2. Equal engine wear. Engines consist of many "wearable" items like bearings, piston rings, springs, etc. Although very unlikely that a 20hr. ski vs. a 30hr. ski will see much difference, it's another variable we wanted to keep out of the equation.
Is speed and acceleration the only thing you judge a PWC on? Not me. .2 seconds is a significant difference???
Next time, get a wind muff for the microphone so we can hear what you're saying.
Gasoline weighs 6 pounds per gallon.
Tbh I would take both but if I had to choose it be sea doo from looks and extra qualities and how your can carry over the weight without dipping in or not leveling out I’m in the market for a sea doo RXT-X or RXP-X but I would buy Yamaha to tbh idgaf what they are as long they hot that 70MPH all talk between people is stupid you take care of your ski the right way is gonna determine its resale and it’s quality life but in the end why are u worried bout he resale if your down hard with Yamaha/seadoo lmao like really
I'm am biased. I own Yama everything, two wheels, four wheels, and on the water. And it may sound crazy, but in the last 19 years, the only thing I have EVER had not start of perform was my grizzly 700. fouled plug. Screw in a new one, it's been going ever since. Like I said, I'm biased. Around these parts, I see mostly Yams and Kaws that are pushed hard. Most guys on the SDs are a little more "mature" (my age group actually now) and aren't racing and jumping. The big Kaws pull hard too no doubt. But still they seem to go to shop more often and sooner. Just looking at the new 2019 FX coming out, Sweeettt! Anybody want to contribute to my NEW SKI FUND? LOL. Be safe out there gentlemen.
Yamaha is solid. Seadoo has more innovation. With more innovation comes a learning curve for the engineers. There is something to be said about simplicity and durability. Seems seadoo is getting it dialed in finally. Owned SeaDoo, Yamaha, and Kawasaki. Had problems with all here and there. But they are all fun!
For fun, we reached out to RIVA Racing and got some hard numbers: the stock Ultra 150 hit a GPS-confirmed 62.5mph with McClugage on it. With some cheap mods, 70mph was capable very easily. 75mph took a bit more. What are all the mods on your '99?
We know the "legendary skis" better than most. And all had paddle wheel speedos that led every knucklehead to think he was Jeff Jacobs out of the box, when in reality blown reeds and calcium-filled carbs stuck 'em around 60mph. What's the old saying, "The older I get, the faster I was?" Yeah, that sounds about right. Produce a radar gun or GPS readout.
Hi all ... I need advice after reading these comments.
I was going to buy a Seadoo 300 RTX, but as someone who is not mechanically minded I am really worried about the number of comments on Seadoo being unreliable and with a questionable service ethic when it comes to replacing engines/parts under warranty.
The techs could tell me anything and I would be none the wiser so I would be an easy target for unethical dealers/manufacturers.
I will do some offshore riding and long distance safaris, but this will be about 35% of the time.
The rest of the time will be relatively flat water where most waves are generated by the surface winds on the water.
I am looking more for adventure, exploring waterways in comfort and style and have no interest in racing other than giving it a good race along every now and then.
+Watercraft Journal You won't believe what happened to me today. As background you need to know that I am jet ski brand agnostic.
I went to a boat show where both Seadoo and Yamaha were present. The Yamaha guys from corporate and sales were there and Seadoo only had sales guys.
I'm interested in purchasing the top of the range Limited models with superchargers.
One thing that really irked me with both brands is that they only allow one colour option for their top of the range jet ski.
I was blown away by this in a world where individual customisation in mass markets has been a 'norm' for the last decade.
You can't get more basic in customisation than colour choice.
It was in 1909 when Henry Ford infamously said "You can have any colour model you want so long as it's black". And that was the beginning of the decline of Ford ... no focus on the customer.
Any business that is not customer-centric is doomed to fail long term ... it is business marketing 101.
Fast forward over 100 years later and Yamaha and Seadoo are saying the same thing as Ford but in a market which EXPECTS some level of individual customisation, especially for the top of the range model.
I can go out and buy a brand new car for cheaper than a jet ski (AUD$25,000 - $30,000 in Australia) and choose whatever colour I want and get other personalised specs as well.
But not with a jet ski ... how retrograde and out of touch with your customers is that!!
And then to add insult to injury the Seadoo Limited GTX 300 colour combo was an insipid silver with putrid brown seats.
I'm a business consultant in this area and I am extremely confident that no marketing research would throw up silver and brown as a popular colour combo. There are some colours that can look good on one model, but terrible on another. The Seadoo 300 GTX falls into the terrible and shocking category.
How Seadoo's marketing department signed off on that colour combo is beyond belief.
At least the Yamaha equivalent has a great colour combo with shades of black, red highlights and some chrome silver detailing. Looks awesome.
The brown seats on the Seadoo looks better with black.
Both companies need to go and look at Lamborghini's Ad Personam Program and their configurator software for que's and clues on how to do this properly.
Very disappointing. Please give this feedback to Seadoo.
Watercraft Journal Thanks, but that still does not reflect the large number of people's personal experiences.
I have checked other sites as well and found more comments about Seadoo's lack of reliability.
We've found that Sea-Doo's corporate customer service have been immensely helpful and forthright with customers. Of course, we typically deal with larger, higher ranked dealerships through the magazine, so we don't have first-hand experience with a shady repair shop. In regards to purchasing a new Sea-Doo RXT-X 300 or other ST3-based PWC, you should be in fine shape as long as you follow the manufacturer's guidelines for use and maintenance and don't void your warranty. We've found the ST3 deck to be one of the most comfortable ergonomically and the sound system the absolute best in the industry!
Not to split molecules but a gallon of gas weighs 6.3 lbs. A gallon of water is 8.6 lb as confused with gas in this video. This honest error accounts for 43.55 lbs. Should mean GP 1800 = around 885 lb fully loaded. When my gp was bone stock I could beat a 2017 RXT-X 300. I have a vid uploaded but I do have to admit it’s close and the RXT is fast as hell. The GP is just a performance beast and it’s rock solid. I ride mine almost every day and have yet to be passed. Thanks for the content!
I'm looking to upgrade from an Aquatrax turbo's. Nothing wrong with my sk'si at 158 and 164hrs on the pair. Just want better handling in rough water. The top speed of 64mph on the stock ski's is no slouch, especially for an 07 model. I'm looking for a new set of ski's and I was torn between these ski's and deciding on which manufacturer to go with. I'm definitely going to order a new GP1800 and a FX Cruiser SVHO. Some friends setup a buoy course a few times a year so the GP1800 will shine and the cruiser will be a perfect blend of performance as well as cruising. My biggest concern was finding a ski that will handle Lake Of The Ozarks Chop, Beaver Lake - Arkansas Chop as well. Thank you for the video
I traded my 2016 RXT 300 X for a 2018 GP-1800 mainly because of the much lighter handling of the Yamaha. The RXT steered like a truck compared with the new Yamaha. ery disappointed in that. Actually my 2008 RXP 215 is still more fun and easier to ride than the 2016 RXT 300X. And, the Yamaha is about 100# lighter than the Seadoo. To be fair, I've never had problems with any of the Seadoos I've owned. Still have the '08 and love riding it. The only modification to the Yamaha is I plugged that STUPID piss hole off the back deck!
Was the big price difference between these two ever mentioned? Not a big deal, I suppose, but I bought a brand new leftover '17 GP1800 for $16,000 out the door with trailer and vest in Alabama last November. Gave 'em a check and that was it. No sales tax, either. I've never seen RXT's or RXP's discounted like that.
That's fine and how it should be for this comparo ... just wondering. It just seems that Yamaha can usually give deeper discounts. And I was wrong ... I should have typed $15,000! Regardless of value, price, etc. this was absolutely the best article of its kind I ever saw despite some of the usual comments section drivel.
I believe the shootouts. But you can't beat the Yamaha solid history, reliability and resale value. Most riders or racers will pick the Yamaha for that reason. The Yamaha will i know for a fact cut through the corners faster than the Seedoos. Seedoo have more features and add-ons . So depending on what you want for your personal use, you may pick either one. I believe Seedoo have improve on their reliability as well. That being said, i pick the GP1800. Adrenaline junky on the track . But if i can buy 2 jetskis, yes ! one GP1800 and one RXT-X
The numbers at 9:00 give the big edge to the Sea-Doo for a drag race. But in a typical race the advantage would be the shortest time to go from medium (say 30mph) to fast (say 50mpg). It looks like the Yamaha has a very small advantage (1.52 vs 1.55 seconds). My guess that there are other reasons why Yamaha has won all the races.
I learned a long time ago that bias is not worth it, smartest business decision I ever made, the best is the best and nothing beats the best except for the best, so remove the labels and bring the best. Sounds Like Sea-doo won until the next best comes around
I’ve owned a 2007 yamaha vx cruiser since brand new with zero hours... never once in the shop... no problems EVER with it...however I would need four even five hands and feet to count how many BRAND NEW Sea Doos I see come through my marina shop with the most rediculous problems from loose wires to no oil or coolant being put in the machines either from the factory or the dealers.... I will never ever ever buy a brp product
Jay Poe not really they have auditers at the end of every production line making sure vehicles leave with all the right fluids and connections done up all the dealers have to do is put the handle bars, seats etc.basically put the accesories on and connect the batteries ive worked at the dealers before..... I’m on my own now... yamaha is way more reliable I’ve seen anyways
Watercraft Journal wow wow, thanks for the reply. Sounds like they are decidedly pretty bad. You just saved me from making a mistake. I'll check out the website and drop a subscribe to your channel, thanks agaib
We've found that the Jettribe vests (the entire lineup) are singularly the most unattractive, poorly designed, uncomfortable and shortest-living "mainstream" brand available. Read our reviews at www.watercraftjournal.com. Contrarily, Slippery makes the single-most comfortable lifevests on the market. Their latest side-entry and front-entry offerings are unusually slim yet 100% meet USCG standards.
great vid, tenth of secs count in racing as racers no...i love yamaha ... have had R6 and R1 sold both now... i just think when it comes to water seadoo takes it and so much speed as in overall watercraft... they are even pushing design, features and innovation of their jet skis for both travel and speed ... love seadoo riding postion.... really depends what u want and r looking for... fam fun seadoo single guy looking for speed and fun GP... shit if u can do both
You say you didn’t want to be bias but you didn’t use the launch control in the seadoo if it came from the factory you should have used it , u are giving the advantage to Yamaha its their own fault for not having launch control on top of that if you wanna compare apples to apples the rxp300 vs the gp1800 cause they are the top race models from each company
I’ve pulled my friends new RXT in similar conditions with my GP1800, both on full tanks of gas, and he’s had days where he just slowly pulled me. Both Great machines, just depends on the day and each individual machine. He’s pulled other stock RXT’s on the lake too. It’s all on the individual machines. Too close to call
That’s close for on the water numbers...splitting hairs on that 5-60mph, not even a full 10th of a second....only 6 one hundredths of a second. The only other thing that would matter would be to try and test in racing conditions...both Impressive machines and fun to ride.
That’s about right for my GTX Limited 300. Full throttle, I’m about 24-25 gallons per hour. I punched it the other day with a completely full tank and the dash said I’d be empty in 31 minutes, lol. Pay to play.
After 26 years of owning a sea-doo, I bought an 18' yamaha this year. Yup switched brands because of reliability. No doubt sea-doo is fast, maybe more comfortable, but man, yamaha handles so well and is so much more reliable. Everyone I know that has a yamaha has so much better luck. We'll see if I eat these words in a few years. 😀
Again, because (and I'll type this really slowly) the RXP-X is HEAVIER and SLOWER than the 2018 RXT-X 300. And what class did Claude win? On his E85 turbo boat made out of carbon fiber? Yeah, SD didn't even celebrate it - except for like, what? A FB meme? Yeah, sorry Charlie. Not comparable.
I always read your articles, and again love your work but you have access to every jetski you can possibly ride, the gp1800 is yamaha's race horse along with the vxr and so i'm at a loss on why u compare it to the T and not the P which is sea-doo's race horse.
The 2018 RXT-X 300 is lighter and faster than the RXP-X 300. It's also outdated. And Sea-Doo is phasing it out shortly. So no, the comparison is sound. Equally, as noted (very proficiently) the GP and T-X are surprisingly close in length and weight, making them suitable comparisons. And we're not seeing a lot of Sea-Doos winning any races, so cest la vie.
My 2017 FX SVHO holds at 75mph. It has hit 77mph while I'm on it alone and ducking down close to the ski to avoid wind resistance. So i guess they forgot the limiter on my wave runner. I haven't had any PWC pass me yet on the waterway.
Alright so the seadoo has the better numbers but as skis the gp1800 is not hard to modify and with the modifications it out does a modified seadoo. The gp is also restricted from the factory to not go over 70.
Yea wish my pos vxr ran. 18 hours and has a new head, ecm, and pump. Not to mention the things the dealer won't file as warranty ive had to fix. I don't get where all these people claim yamaha water craft are superior. Mine sucks. Fun when it runs. Key word "when "
surprising that the Rxt-x 300 has a smaller motor 170cc smaller crazy I know BRP has really turned Evinrude around and build some quality boat motors now and love my 2012 90 E-Tec but hay i also love Yamaha products have owned many Yamaha bikes and they make excellent boat motors also can not go wrong with either one great shoot out guys
Torn between a VX limited, VX cruiser HO, or GTX 230 limited. My 1st waverunner purchase. Me, wife, 10 yr old, 4 yr old. Will be family ski. Tr-1 fuel economy and safety, 1800 n/a upgrade, or supercharged fun. What do we choose?
Sorta. The big plus of the VX Limited is the raft to tow behind it with the kid (well, that and the cover). Ride wise – either VX will ride the same. The GTX is a wholly different machine (larger, heavier, more stable), and might be a better choice given the rough ocean conditions.
Awesome, thank you for your quick response. Not questioning your choice but wonder if your recommendation would change if you knew the ski would be in salt water 75% of the time. Or is there a choice out there I might be leaving out? Thanks
The skis were ran literally minutes from each other with no difference in wind, ambient temperature or water temp. And maxed fuel was the only way to PROVE WITHOUT A DOUBT that we weren't sandbagging one or the other.
Mark G i have owned a 2010 gtx 255 limited si and holly moly that ibr... maaaaaan broke down like 4 times, in 2016 i bought a 2012 fx cruiser ho that has been bulletproof in all aspects. Don't know man... i not had a good xperience with sea doo. Pará Brazil
Seadoo has done much better on the motors they aren't normally the issue for me its the IBR I have seen several people have issues with it and if it goes out while your out on the water and stuck in neutral your screwed.
