The Sea Doo FishPro Apex 300 2025 vs Sea Doo GTR X 300 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 FishPro Apex 300 2025 measures 146,8 feet overall (2025), giving it roughly 16,1 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 FishPro Apex 300 2025 tips the scales at 978 lbs — 184 lbs more than the Sea Doo GTR X 300 2025 at 794 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.
Both boats share a closely matched power ceiling — 300 hp for the Sea Doo FishPro Apex 300 2025 and 300 hp for the Sea Doo GTR X 300 2025. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. 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 FishPro Apex 300 2025 is rated for 44 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 FishPro Apex 300 2025 could be the deciding factor.
Bottom line: Choose the Sea Doo FishPro Apex 300 2025 if your priority is putting more people on the water — it handles 44 passengers and at 146,8 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.
