I tried to send you a PM but it's not working, if I read your thread correctly you are interested in buying a GN style boat and asking about the RUSH boats. I have one its my second RUSH, the current one is set up for family ski/race. I have owned alot of boats from schaida 21 to hallett vectors all set up for race, I know this will piss off the schiada and vector boys but a RUSH in it's worst day will smoke both those boats in any water condition and not to mention they turn on a dime! The only boat that compares is a Rayson-Craft. Grier Rush, I think made less than 15 of them? it's a true custom on of a kind GN boat. Mine has a Blown/Intercooled 598'. My boat was rigged for GN racer Van Vanucci back in 1985, it had a blown injected 557 in back then, he was try to set a record at the Parker Kilos went bankrupt trying to do it!
