Haha, I've known JP my whole life as him and my dad were old friends and would drag race at the river especially Lost Lake, Paradise Point, etc. He's always one to keep his numbers to himself. I think the yellow one with a good shot should be comparable to Rausher's (your boat) boat when he ran it. You too would be a pretty good race right now actually as you both have 505's. Those old guys had some tricks to river racing though with the jockeying at the start. We ran a blown alcohol flat to beat Joe because he was a good driver and a heavy flat has to play catch up.
I was trying to buy the yellow one myself, but I'm such a cheap ass his son in law got it before me.
I have no idea on what it would run, but its more of a family sedan than a race boat. It may get a big procharged motor this winter though. Turbos are too scary around a 4 year old and I like the drive-ability of no boost at cruising.
