The Malibu Boats Wakesetter 21 LX 2023 vs Malibu LXi 2009 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.
The power gap is worth calling out. Rated to 430 hp, the Malibu Boats Wakesetter 21 LX 2023 has a 30-hp advantage over the Malibu LXi 2009's 400-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Malibu LXi 2009 carries 41 gallons versus 5 gallons in the Malibu Boats Wakesetter 21 LX 2023. 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 Malibu LXi 2009 is rated for 9 passengers, while the Malibu Boats Wakesetter 21 LX 2023 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Malibu LXi 2009 could be the deciding factor.
Bottom line: Choose the Malibu LXi 2009 if your priority is putting more people on the water — it handles 9 passengers and at 2,0 ft it has the deck room to back that rating up comfortably. The Malibu Boats Wakesetter 21 LX 2023 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
