I'd recommend that a monsoon in a VLX or LSV would better preform w/ a OJ 468 prop even over the Acme 1235. The LSV is 102" beam vs the VLX is 98" some like the wider wake others don't. Properly loaded the LSV has the potential to produce a better surf wake. I know several that have have LSV's w/ the monsoon and they work just fine, if you plan on loading them up w/ a couple grand of extra ballast plus a full boat load of crew it might stuggle a bit even w/ the OJ 468. If you plan on cruising around to a ride location keep in mind these lower props are great to get out of the hole and hold speed superb, but on average the rpm's are ~800-1,000 more than the stock prop typically an Acme 537. The monsoon is the only engine across all Indmar lines that has been trouble free and rock solid, we all like more power but.... The dash on the '08 LSV is different than any other boat in that model year, most of us commented we didn't care for it and viola it didn't make it past one year. You can upgrade the '08 dash to take advantge of some of the '09 model year options, ushc as Malivue. The '08 will stiff have some of the warranty left provided it's got less than 300 hours, the '07 is most likely out of warranty. As the dealer if the hull warranty can be transfered, they'll need to do the inspection and costs ~ $275.
Regardless which boat you pick I'd recommend extra weight up front, these boats need it imho.
