The Sea Doo GTR X 300 2025 vs Sea Doo RXT-X 325 2025 comparison sits squarely in the category of decisions where specs alone won't tell the whole story: intended use, storage, and long-term ownership costs all factor in.
Size is the most obvious dividing line here. The Sea Doo RXT-X 325 2025 measures 135,8 feet overall (2025), giving it roughly 5,1 additional feet of deck space compared to the Sea Doo GTR X 300 2025 at 130,7 feet (2025). Weight tells a clearer story for trailering families: the Sea Doo GTR X 300 2025 tips the scales at 794 lbs - 152 lbs more than the Sea Doo RXT-X 325 2025 at 642 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.
The power gap is worth calling out. Rated to 325 hp, the Sea Doo RXT-X 325 2025 has a 25-hp advantage over the Sea Doo GTR X 300 2025's 300-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads - 19 gal and 19 gal - so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Sea Doo RXT-X 325 2025 is rated for 41 passengers, while the Sea Doo GTR X 300 2025 caps at 39. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Doo RXT-X 325 2025 could be the deciding factor.
Bottom line: Choose the Sea Doo RXT-X 325 2025 if your priority is putting more people on the water - it handles 41 passengers and at 135,8 ft it has the deck room to back that rating up comfortably. The Sea Doo GTR X 300 2025 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 39 that costs less to run day-to-day.
