The spec sheets list the Malibu Wakesetter 23 LSV 2007 as modified vee and the Malibu Wakesetter 247 LSV 2008 as v25, so check how each hull rides in the conditions you use before you decide.
On paper these two are close siblings in the size department - Malibu Wakesetter 23 LSV 2007 at 23,0 ft versus Malibu Wakesetter 247 LSV 2008 at 24,0 ft. At 3 900 lbs and 4 000 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.
Both boats share a closely matched power ceiling - 450 hp for the Malibu Wakesetter 23 LSV 2007 and 450 hp for the Malibu Wakesetter 247 LSV 2008. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Malibu Wakesetter 247 LSV 2008 carries 87 gallons versus 55 gallons in the Malibu Wakesetter 23 LSV 2007. 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 23 LSV 2007 caps at 14. 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 23 LSV 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 14 that costs less to run day-to-day.
