Matching a modified vee Malibu Wakesetter 21 XTi 2005 against a v25 Malibu Wakesetter 247 LSV 2008 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
On paper these two are close siblings in the size department — Malibu Wakesetter 21 XTi 2005 at 21,0 ft versus Malibu Wakesetter 247 LSV 2008 at 24,0 ft. At 34 lbs and 4 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The power gap is worth calling out. Rated to 450 hp, the Malibu Wakesetter 247 LSV 2008 has a 50-hp advantage over the Malibu Wakesetter 21 XTi 2005'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 Wakesetter 247 LSV 2008 carries 87 gallons versus 46 gallons in the Malibu Wakesetter 21 XTi 2005. 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 Wakesetter 247 LSV 2008 is rated for 16 passengers, while the Malibu Wakesetter 21 XTi 2005 caps at 12. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Malibu Wakesetter 247 LSV 2008 could be the deciding factor.
Bottom line: Choose the Malibu Wakesetter 247 LSV 2008 if your priority is putting more people on the water — it handles 16 passengers and at 24,0 ft it has the deck room to back that rating up comfortably. The Malibu Wakesetter 21 XTi 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 12 that costs less to run day-to-day.
