The Sea Doo 180 Challenger 2008 vs Sea Doo FishPro Sport 170 2022 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 Sport 170 2022 measures 146,8 feet overall (2022), giving it roughly 129,1 additional feet of deck space compared to the Sea Doo 180 Challenger 2008 at 17,7 feet (2008). Weight tells a clearer story for trailering families: the Sea Doo 180 Challenger 2008 tips the scales at 1 913 lbs — 1 055 lbs more than the Sea Doo FishPro Sport 170 2022 at 858 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 255 hp, the Sea Doo 180 Challenger 2008 has a 85-hp advantage over the Sea Doo FishPro Sport 170 2022's 170-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Sea Doo 180 Challenger 2008 carries 28 gallons versus 19 gallons in the Sea Doo FishPro Sport 170 2022. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The Sea Doo FishPro Sport 170 2022 is rated for 44 passengers, while the Sea Doo 180 Challenger 2008 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Doo FishPro Sport 170 2022 could be the deciding factor.
Bottom line: Choose the Sea Doo FishPro Sport 170 2022 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 180 Challenger 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
