I dont doubt your numbers. I personally drove an Allison with a bone-stock 150XR6 with a 28″ chopper Allison modified and sold back in the early 90s, and it broke 80 mph on radar, with me driving and holding the radar gun. I found it hard to believe, but I saw it. And no, it wasnt a 200 in 150 clothing, it was _my_ XR6 that we were playing with. Just not my boat.I was just pointing out that your numbers are very good. Lots of explanations, from a motor with tight tolerances, which happens, to a prop that is dead on with pitch, rake and cup, etc…70 isnt impossible. Just rare.congrats… 2008 Pantera Classic2014 Mercury Pro XS 200
