2027 Sea-Doo RXT-X vs. RXP-X: Which One to Choose?

By the Groupe Contant Team · Published October 24, 2026

Quick Answer

RXT-X or RXP-X: what's the difference?

Both watercraft have the same 350 hp Rotax 1630 ACE engine, a 70 L fuel tank, a 125 cm width, a 10.25 in. touch display and iBR with audio. The difference is the hull and the purpose: the RXT-X has the ST3 hull, carries up to 3 people and is built for stability in rough water, with Ergolock ergonomics and a 3-position hydraulic steering damper. The RXP-X has the T3-R hull, race-focused ergonomics and one seat (up to 2 with the accessory seat); it's lighter (362 kg versus 382 kg dry) and shorter. Pick the RXT-X for performance on open water with company; the RXP-X for tight carving, mostly solo.

The RXT-X and the RXP-X are Sea-Doo's two performance watercraft, and BRP gives them the same engine: the 350 hp supercharged Rotax 1630 ACE, which it presents as the most powerful factory engine in the industry. What sets them apart is where they shine. BRP describes the RXT-X as purpose-built for offshore riding, stable and controllable even in rough conditions, and the RXP-X as built to dominate the buoys, with razor-sharp carving ability.

This comparison relies only on BRP's 2027 model-year data for dealers (RXT-X 350 and RXP-X 350).
