I am curently looking at buying a 2009 z21 dual console with a 250hp yamaha vmax hpdi siting on a 10in jack plate and i was wondering what kind of top speed you guys are geting with a similar set up with all your gear, live wells full and a decent amout of gas in the tank. The one i am looking at, the owner says it goes 67-68 at 5700 rms. thanks for any input on answering my quiestion.
