I have a 97, 215, and currently have a 150 hp etec. My cruising speed is 30 mph at around 4000 rpm. I can get her over 40 mph at 5500 rpm if I'm running her lite. (less than 1/2 tank of fuel, no gear, no passengers etc etc)
Keep in mind the weight on board plays a big part in speed. Full fuel tank vs half, amount of people on board, and gear. Prop pitch will also dictate speed. A lower pitch will pop the boat on plane quickly but you lose top end. This is good for pulling skiers. A higher pitch will give you more top end but she be slower climbing out of the water to get on plane.
