Detailed Evaluation & Buyer Recommendation
Sea Doo GTX 170 2025 vs Sea-Doo Challenger 1800 (240hp) 2003 — Same Brand, Different Boat
The Sea Doo GTX 170 2025 vs Sea-Doo Challenger 1800 (240hp) 2003 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 GTX 170 2025 measures 135,9 feet overall (2025), giving it roughly 118,9 additional feet of deck space compared to the Sea-Doo Challenger 1800 (240hp) 2003 at 17,0 feet (2003). Weight tells a clearer story for trailering families: the Sea-Doo Challenger 1800 (240hp) 2003 tips the scales at 1 865 lbs — 1 069 lbs less than the Sea Doo GTX 170 2025 at 796 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 240 hp, the Sea-Doo Challenger 1800 (240hp) 2003 has a 70-hp advantage over the Sea Doo GTX 170 2025's 170-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 7 gal and 4 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Sea Doo GTX 170 2025 is rated for 41 passengers, while the Sea-Doo Challenger 1800 (240hp) 2003 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Doo GTX 170 2025 could be the deciding factor.
Bottom line: Choose the Sea Doo GTX 170 2025 if your priority is putting more people on the water — it handles 41 passengers and at 135,9 ft it has the deck room to back that rating up comfortably. The Sea-Doo Challenger 1800 (240hp) 2003 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
