I give the boat thumbs up. I think you'll enjoy it! It's comparable to the Hammer(same hull, set-up) which I owned in 2000. It's a fast platform and is fairly comfortable in most light chop conditions(1'-2'). It's got a 21* bottom which is a little more bumpy than most of the deeper(23*-25*) vee boats. Nonetheless, it's faster for it and planes pretty quickly.
The numbers you quoted seem to be in check. 35,000 is about right for the way the boat is set-up. A quick search on www.boattraderonline.com yielded very similar numbers.
The 6.2MX is rated for an rpm range of 4800-5200rpm. So, assuming the set-up falls within that range, the boat should see about 65mph average at 5000rpm.
Hope this helps. Good Luck!
