Detailed Evaluation & Buyer Recommendation
Sea-Doo 180 Challenger SE (255 hp) 2009 vs Sea-Doo RXP-X Senna 350 2027: Same Brand, Different Boat
The spec sheets list the Sea-Doo 180 Challenger SE (255 hp) 2009 as modified vee and the Sea-Doo RXP-X Senna 350 2027 as t3-r hull, so check how each hull rides in the conditions you use before you decide.
The power gap is worth calling out. Rated to 350 hp, the Sea-Doo RXP-X Senna 350 2027 has a 95-hp advantage over the Sea-Doo 180 Challenger SE (255 hp) 2009's 255-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 SE (255 hp) 2009 carries 32 gallons versus 19 gallons in the Sea-Doo RXP-X Senna 350 2027. 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 180 Challenger SE (255 hp) 2009 is rated for 8 passengers, while the Sea-Doo RXP-X Senna 350 2027 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea-Doo 180 Challenger SE (255 hp) 2009 could be the deciding factor.
Bottom line: Choose the Sea-Doo 180 Challenger SE (255 hp) 2009 if your priority is putting more people on the water - it handles 8 passengers and at 17,0 ft it has the deck room to back that rating up comfortably. The Sea-Doo RXP-X Senna 350 2027 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 1 that costs less to run day-to-day.
