Is there still a Sea-Doo RXT without the X?

Not in BRP's 2027 lineup: the RXT line comes in a single version, the RXT-X 350.

Is there a 350 hp GTX?

Yes, the GTX Limited 350, which BRP lists as a separate model line. It has the same power as the RXT-X 350 and lists iBR, iDF and audio.

What licence do I need to ride a watercraft in Quebec?

The rules are the same for both models. See our guide to the licence needed to ride a Sea-Doo in Quebec.

BRP lists a one-year limited warranty on the watercraft, for both the 2027 RXT-X and GTX.

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

By the Groupe Contant Team · Published October 24, 2026

Quick Answer

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

Both watercraft share the fiberglass ST3 hull, the Rotax 1630 ACE engine, 3 seats, a 70 L fuel tank, 98.9 L of storage and the 10.25 in. touch display. The RXT-X is the performance watercraft: 350 hp, the Ergolock system and a 3-position hydraulic steering damper, built for rough water. The GTX is the touring watercraft: 170, 230 or 300 hp, comfort-focused seating, a large swim platform with LinQ attachment points and the iDF debris-free pump. Pick the RXT-X for power in rough water, the GTX for comfort on long rides.

When people search "RXT vs GTX", in 2027 they're comparing the Sea-Doo RXT-X and the Sea-Doo GTX: BRP no longer offers an RXT without the X, and the RXT-X comes in a single version, the RXT-X 350. Both watercraft use the same ST3 hull and the same Rotax 1630 ACE engine, but BRP presents them very differently: the RXT-X is "purpose-built for offshore riding", while the GTX is a touring watercraft focused on comfort.

This comparison relies only on BRP's 2027 model-year data for dealers. The GTX comes in three versions (GTX 170, 230 and 300): we name the version whenever a figure changes.
