The 2026 Sea-Doo RXT-X 325 has come in for subtle but significant changes for the new model year.
While it carries over the same 325hp engine as before – the most powerful among its peers, and the same engine shared with the RXP-X 325 and GTX Limited 325 – the Sea-Doo RXT-X gains this awesome new Gulfstream Blue colour option for 2026.
Plus it comes with a new 10.25-inch touchscreen – the largest in the jet ski world to date– and new toggle switches on the handlebars to more easily access the controls.
With these updates, plus all of the other attributes that make the Sea-Doo RXT-X so great, we reckon this one of the best skis on the market today if you are after performance and practicality.
In this review we cover prices in Australian and US dollars, tell you what it’s like to ride, and go through the pros and cons.
Plus, as always, we completed acceleration and top speed tests using precision VBox timing equipment.
2026 Sea-Doo RXT-X 325 feature highlights
For 2026, the Sea-Doo RXT-X is available in Gulfstream Blue as the optional hero colour, while the standard colour scheme called Ice Metal (with Manta Green highlights) carries over for the third year in a row.
The new 10.25-inch display and new toggle switches that made their debut on the Sea-Doo GTX Limited in 2025 have since been applied to seven top-end models across the Sea-Doo range for 2026, including the RXT-X.
The new touchscreen means riders can access the various functions of the craft more quickly and easily, while still being able to use the redesigned handlebar toggle switches if you prefer.
Launch control and sports mode are now just a finger tip away.
And when you pair your smartphone via the BRP Go app, you can access a range of maps for easier navigation. Plus it’s now easier to stream music.
The touchscreen works best with bare finger tips, and works most of the time with gloves. But it can struggle sometimes responding to inputs with wet gloves.
Sea-Doo’s industry-first steering damper set-up made its debut a few years ago and carries over onto more models for 2026.
A turn of the dial makes the steering heavier or lighter, so you don’t turn the handlebars too aggressively at speed and eject yourself off the ski.
There is a lot of power under the seat. This is third year the upgraded 325hp engine has been available in the Sea-Doo RXT-X after receiving a power boost from 300hp in 2024.
The supercharged 1630cc three-cylinder Rotax engine with 325 horsepower is the most powerful engine from the three major Jet Ski brands.
Supercharged Kawasaki models top out at 310hp and supercharged Yamaha WaveRunners have about 280hp, although this is an estimate because Yamaha does not provide horsepower figures.
2026 Sea-Doo RXT-X 325 prices
In Australia the 2026 Sea-Doo RXT-X 325 starts from $34,899 (excluding trailer and registration). In the US the price starts from $US21,899.
These prices make the RXT-X one of the most expensive models in the Sea-Doo catalogue. Only the GTX Limited 325 is dearer.
Be sure to check for any additional costs with your local Sea-Doo dealer.
Note: the US only has a one-year warranty, but in Australia Sea-Doo offered two-year coverage as this review was published, with three years offered during special promotions, so be sure to check the Sea-Doo Australia website.
2026 Sea-Doo RXT-X 325 specifications
Not to be confused with the mid-size Sea-Doo RXP-X 325 – which is a slightly smaller, race-bred peformance ski, and which we cover in a separate review – the RXT-X 325 we are testing here is based on Sea-Doo’s full-size ST3 platform.
It’s the same hull and top-deck design that forms the basis of the Sea-Doo Fish Pro, Explorer Pro and GTX series.
That means the Sea-Doo RXT-X has a larger and more comfortable seating area, a larger rear deck, and – best of all – it comes with a genius bow storage compartment.
Sea-Doo ST3 models such as the RXT-X have easiest access to bow storage of any watercraft on the market today.
Simply release two tabs and lift the centre console lid and handlebars up as one, then lean in to grab whatever you need.
To access the bow storage on a Yamaha or Kawasaki, you need to reach over and precariously balance your body on the handlebars.
While the RXT-X does not have as much bow storage as its rivals, it is still big enough to suit most needs – and is much more user friendly than anything else on the market.
It’s worth noting the weight limit of the Sea-Doo bow storage area is 14kg or 30 pounds, so it’s better suited to towels and other beach gear rather than anything super heavy.
Helpfully there are mesh pockets at the top of the compartment, so you can grab and go. Ideal for carrying bottles of water or tubes of sunscreen.
Under the centre console lid are recesses with rubber straps to hold a fire extinguisher and an emergency beacon.
Within the bow storage console hood / lid is a small glovebox with a waterproof compartment for a phone, wallet or car keys.
There is a piece of foam to stop your smartphone from getting knocked around. And there is a USB charge port to keep your device powered up.
However you may need to shop around for a USB charge cord with a small plastic shroud, because the lid may not snap shut.
Smartphones already housed in waterproof cases can be a bit bulky to store, so you may need to make some adjustments or remove the foam.
For 2026, the USB charge port has a cap to help prevent corrosion, debris or water ingress when not in use.
The fuel filler neck is up high and located under the centre console lid. This makes it easier to refuel when you’re on the water or when refuelling on a dock.
The fuel filler on most Yamaha models is down on the nose of the craft, near the water line, which is fine if you’re refilling at a gas station while the vessel is on a trailer, but it’s not ideal when refuelling on the water.
There are tie-down points on either side of the bow, to tie off on a dock.
Plus you can use the rear seat hand rails as attachment points at the rear of the craft.
The Linq accessory cleats are intended to keep a Sea-Doo fuel caddy in place, or you can also use the rear deck to attach a Sea-Doo cooler box.
With the Linq accessory cleats retracted, you can use the rear deck as a swim platform.
Helpfully the RXT-X comes standard with a rear boarding rail, which makes it easier to get back onto the craft from the water.
To find the ideal riding position, the handlebars are tilt adjustable. Simply release the tab and then allow it to click back into place.
The handlebars and information display tilt as one unit, so the rider has clear visibility of the digital dash.
This tilt adjustment makes it easier to find a comfortable position whether you are standing or sitting.
It also helps riders of different heights find their most comfortable stance.
Unlike Yamaha WaveRunners and Kawasaki Jet Skis, the Sea-Doo RXT-X has a narrow seat design which reduces the risk of chafing on your legs.
The Sea-Doo RXT-X also has padded protection up high near the centre console, to cushion the knees of riders who prefer to sit down.
The footwells are wide, so there is plenty of room for your legs and feet, whereas the footwells in the equivalent Yamaha FX WaveRunner tends to be a little narrow.
To access the engine bay for routine maintenance between rides (such as giving the engine compartment a quick squirt with silicon spray or an anti-corrosion aerosol) first remove the rear seat section by releasing two tabs, and then remove the forward seat section after releasing one large tab.
The whole assembly clips back into place by reversing this process.
Finally, the audio speakers are epic. Optional in the US but standard in some markets, including Australia. We highly recommend these.
Sea-Doo’s premium audio system is the best in the Jet Ski market today. Better than the four-speaker set-up on the Kawasaki Ultra and better than the new Yamaha audio speakers on the latest Yamaha models.
2026 Sea-Doo RXT-X 325: What’s it like to ride?
Sea-Doo performance models launch hard because they come standard with a scoop grate, where large curved fins direct water straight into the impeller.
This reduces cavitation on take-off and delivers almost instant acceleration.
The downside is that, in our experience, Sea-Doos tend to suck up more debris than other brands.
For now, Sea-Doo’s reverse thrust debris removal system is not yet available on the RXT-X or RXP-X 325 performance skis.
Meanwhile, as we’ve noted with other Sea-Doo models based on the ST3 hull, the nose of the RXT-X tends to bounce around in rough conditions.
The bow of Sea-Doo ST3 models have a noticeable concave shape, which helps deflect water spray.
You get a much drier ride, but the downside of this design is that the bow hops around in cross chop – also known as bow hunt – especially as the fuel load gets lighter.
When there is more weight over the nose, the bow tends to dig into the water a little more. But as soon as the fuel load lightens, medium size waves or the wash from other vessels tend to play havoc with the front end.
In comparison, the bow of the Yamaha FX and Kawasaki Ultra models have a more forgiving, convex bow design which are better at carving through rough conditions.
That said, if you are going to ride primarily in calm waterways such as rivers and lakes, this is a non-issue. In these conditions, the Sea-Doo ST3 hull – including this RXT-X – is brilliant to ride.
These comments about bow hunt mainly apply to Australian buyers where ocean riding is more popular due to restrictions on certain inland waterways.
The RXT-X might be a large, full-size ski but it still handles sharply, due in part to the high performance sponsons which are designed to carve into the water for tighter turns.
While some thrill seekers might consider fitting even more aggressive sponsons, we would advise against it.
The factory fitted sponsons already make the RXT-X super-responsive.
Indeed, these sponsons are part of the reason Sea-Doo introduced a steering damper, because the RXT-X can turn sharper than most riders can handle.
Meantime, when you’re cruising in a go-slow zone, the cruise control function is now easier to operate thanks to the toggles on the handlebars – and the system will even remember your last preset speed until you key off.
To cancel cruise control, simply tap the reverse trigger on the left, or the accelerator trigger on the right … Or hit cancel.
Need to switch off the engine in a hurry? Just pull the lanyard which will unplug the ignition key from its fitting.
This is also how the engine switches off if the rider goes overboard, as long as the lanyard is attached to the rider’s safety vest or wristband.
2026 Sea-Doo RXT-X 325: Speed tests
As always, we performance tested the RXT-X using precision VBox timing equipment, which uses satellite technology to measure acceleration.
We set the VBox to start from 5kmh or 3mph, because the slightest movement on the water triggers the device.
Our rider weighed 100kg or 220lbs and the temperature on the day was a mild 20 degrees Celsius or 68 degrees Fahrenheit.
We started with a full tank of fuel in the 70-litre (or 18.5 US gallon) fuel tank.
These results are an average of four runs, two in each direction, to account for wind direction and water current.
Your results may vary but this is what we got on the day with a factory standard ski with about six hours on the clock.
We did a series of four runs with launch control activated – which trims the nose down on take off and then lifts the nose as the speed climbs – and another four runs with the trim set in neutral all the way, and the figures were essentially the same.
It’s important to note we tested the RS version of the RXT-X 325 – even though it no longer comes with RS labels – which is standard in Australia.
RS models have a higher top speed than the units sold off the shelf in the US, where the RXT-X is obliged to meet US coast guard top-speed requirements.
The US version of the RXT-X has a speed limiter set to about 112kmh or 70mph, whereas the RS version sold in Australia tops out just shy of 120kmh or 75mph.
In our test of the RXP-X in Australia we nudged 118.1kmh (or 73.4mph) in one run going with the wind and the water current – and recorded an average top speed of 117.3kmh (or 72.9mph) after splitting the difference across four runs, two in each direction.
Translation: this is one of the fastest skis on the water, straight out of the box.
As we noted in our test of the 2026 RXP-X with the new 10.25-inch display, the speed limiter on the 2026 RXT-X also kicks in quicker due to the faster processing speed of the new touchscreen, which monitors and displays the speed of the craft based on a GPS signal.
That said, no matter how you measure it, the RXT-X is phenomenally quick.
At its core is the race-bred supercharged 1630cc three-cylinder Rotax engine, which was boosted from 300hp to 325hp three years ago after Sea-Doo developed a new supercharger, new fuel pump, new electronic control module, new fuel injectors, new air intake, new exhaust manifold and an O2 sensor to more accurately measure the fuel mixture.
As we’ve reported previously, the 325hp engine feels a lot stronger in the middle of the rev range and doesn’t get an asthma attack at the top end either. It feels like the power is never ending.
The result is a much more responsive engine and one that feels tireless all the way to its top speed.
Here’s how some other supercharged Jet Skis compare based on our latest VBox testing:
- Sea-Doo RXT-X 325 RS
5 to 100kmh 4.61 seconds
3 to 62mph 4.61 seconds - Kawasaki Ultra 310X
5 to 100kmh 5.23 seconds
3 to 62mph 5.23 seconds - Yamaha FX SVHO
5 to 100kmh 5.33 seconds
3 to 62mph 5.33 seconds
The RXT-X 325 and the RXP-X 325 (4.57 seconds) are the only craft we have tested so far that make it into the 4 second bracket at 100kmh or 62mph.
The only downside to all this performance is fuel consumption.
While the RXT-X has similar fuel consumption compared to other supercharged Jet Skis, it is understandably thirstier than Sea-Doo’s super efficient non-supercharged models.
That said, if you cruise along at modest speeds and don’t exploit its full potential, you can certainly get more out of a tank.
The Sea-Doo RXT-X consumed fuel at a rate of 65L/100km (or about 3.6 miles per gallon) during our time with the craft.
This rate of consumption is comparable with the Yamaha FX SVHO powered by a 1.8-litre supercharged four-cylinder engine, and the Kawasaki Ultra 310 powered by a 1.5-litre supercharged four-cylinder engine. Based on our testing.
This is the trade-off if you want to accelerate this fast and unlock this much performance.
2026 Sea-Doo RXT-X 325: The verdict
To sum up, the 2026 Sea-Doo RXT-X 325 is one of the best skis we’ve tested as it combines supercharged performance with straightforward practicality.
The easy access bow storage compartment is a game changer, the large rear deck can accomodate a range of accessories – or you can use it as a swimming platform – and it has the best audio system on the market today.
Based on Sea-Doo’s full-size ST3 deck and hull, it can carry up to three occupants – however we prefer riding solo, especially at speed.
The new 10.25-inch touchscreen brings the latest technology to the RXT-X, giving it a class-leading edge. It’s easy to use and is a welcome update to this model.
And the new toggle switches on the handlebars are also more user friendly than the previous design.
In our opinion the RXT-X is a brilliant blend of performance, practicality and comfort.
But if this is your first ski, please take it easy and build up to its capabilities, because it is an extremely quick machine.
