Just purchased the 2017 Nitro Z18 with the 150hp Four Stroke. Just finished the 10 hour break in and opened the throttle a little. Easily brought her to 60mph with a little throttle and a lot of trim left. It's the Silver/Red/Black color scheme. I traded in a 2006 Skeeter SX180 115hp. Huge difference. The ride is smooth. As with any boat if you cut across big wakes at high speed your gonna feel it. If you angle them, with the hydraulic steering you'll breeze right through them with ease.
