Trim X – First Gen Max Trim Kit
Unlock the full trim potential of early-model Sea-Doos with the First Gen Max Trim Kit. Designed specifically for older platforms, this bolt-in upgrade delivers a solid trim increase while keeping the ski’s reliability and long-term durability intact.
Although the trim gain isn’t as significant as our newer-model kits, it still maximises the available trim angle on these earlier Jet Skis, giving you better lift, cleaner spray, and a more responsive ride.
Built tough, made to last, and our cheapest Trim X kit yet, this is the perfect upgrade for riders wanting extra performance without overcomplicating the install.
Suitable Models:
As seen below:
GTR / GTI: 2016–2019
RXT-X / GTX: 2016–2017
RXP-X: 2016–2020

Great customer support! Must have for anyone running a Seadoo engine / pump in a mini jet boat. I got the 1st gen kit for my 2019 RXPX 300 inside my 12ft boat. Completely changed how the boat handles in the best way.

Put this in a 12 foot mini jet boat. Was pleasantly surprised how much roost it gave me. Cheap alternative to going other routes for getting more spray. Did notice loss of rpm with trimmed all the way up and no speed gain. Also lost some clicks for trimming down. Other than that happy with the product and simple installation.

Parcel arrived just in a few days. It was easy to replaced. Water splash was much higher than usual after tail flick trick. Too bad we can't get stage 2 nossle on our 2016 model. My son would love that rooster tail look.

Not much change in regards to jet spray, but noticeable improvement in acceleration and the ability to launch of even small waves.

Just installed love it really can’t see the roaster tail so I recorded it today it jumps out of the water now trimmed up it’s installed on a 2025 GTI SE 170 as of today with 16 hours. I noticed the more powerful full throttle bow jumping up sharper turns handling when I got on it in sport mode from the dock. Very noticeable difference from stock. I’m in the USA and seller says use the grease on the bolts to back the kit didn’t come with a small tube of it. I’m in Florida salt water… Packaged professionally in foam exact form fit I’d recommend it to add some playfulness and took me 15 minutes to install .

Fantastic device, Easy mount. Small minus is the reversing in Neutral. Working on it - and i think the solution is near. Good service and answer from Trim X.

Did the nozzle paired with the iBR grind down and recalibration and man my GTR-X 300 turned into my old TRIXX in seconds! I used to love the crazy bunny hopping from holeshots I used to get, major spinouts and how could I forget by doing wheelies especially solo on a 800+lb ski! Best purchase I have done to change the entire dynamic of the ski characteristics.
Kristian G. 5/5 Verified
Huge difference!!!! I just had to re set the neutral on the IBR. Now it’s perfect. A lot of fun on my 325 GTX.

"When the trim angle is raised to the maximum, the jet ski jumps better and the angle of the water being discharged is also improved."

Truly bolt in and go makes the ski an absolute blast makes it a total different experience

10/10 by far the best thing I’ve bought for my ski. The roost is so much bigger and person and so much fun on a flat calm day, I would absolutely recommend it to anyone that wants to buy it.
Harry G. 5/5 Verified
I honestly can’t recommend TrimX enough. The quality of the nozzle is outstanding, and you can tell a lot of engineering went into it. Installation was straightforward, and the difference on the water was immediately noticeable. The handling feels much sharper, the ski hooks up better in turns, and it makes tricks like spins, wheelies, and playing around on the water way more controlled and predictable. It completely changed the personality of my jet ski—it feels more responsive, more planted, and a lot more fun to ride. The build quality is top-tier, and everything fits perfectly. It’s one of those upgrades where you wonder why the ski didn’t come like this from the factory. If you’re thinking about upgrading your Ski, this is one of the best mods you can buy. It genuinely transforms the riding experience and is worth every penny. Huge thanks to the TrimX team for making such an incredible product!
Ahmed H. 5/5 Verified
Was a bit of a wait for it to ship but once it shipped it was here within 3 business days. Put it on my 2022 RXT-X and it changed the whole ski. The roster is crazy and the wheeliess are another level. Only this is it loves to jump out of the water off plane no matter where the trim is and I don’t really have a neutral anymore it likes to drift backwards. But I would definitely recommend it.
