Sea-Doo GTX 300, 230 & 170 Parts & Upgrades
Parts for the Sea-Doo GTX Limited 300 (2016–2025), GTX 230 / GTX Limited 230, GTX 170 and the earlier GTX 215 and 260 (2008–2015). Since 2018 the GTX rides on the ST3 hull shared with the RXT-X, and the GTX Limited 300 runs the same supercharged 1630 ACE 300 as the RXP-X and RXT-X. The 230 is the supercharged 1630 in lower tune; the 170 is the naturally aspirated 1630.
So most engine, supercharger, intercooler, exhaust and intake parts in our RXP-X & RXT-X collection fit the GTX 300 directly, and ST3 hull parts (intake grates, ride plates, seat covers, siphon break deletes) fit both the GTX and RXT-X. Check the engine (300 / 230 / 170) in each product title.

Tuned here, shipped from Florida
We calibrate the 1630 ACE daily. For a GTX Limited 300, start with a GTX ECU tune, then intake and intercooler. It responds like an RXT-X. Tell us your year and engine before you order and we'll confirm fitment.
