asas 2009 TRACKER MARINE NITRO X-4 ssdsz in Norfolk, VA

We tested the Nitro Z21 with a 250-hp Mercury 250 L OptiMax Pro XS with a Torque Master gearcase and the boat hit a top speed at 6000 rpm of 71.1 mph (114.4 kph). Best cruise was found to be at 4000 rpm and 39.9 mph. That reduced the fuel burn to 9.0 gph and increased the range to 219 statute miles, while still keeping a 10% fuel reserve. The Rapid Planing System lived up to its billing with the boat leaping on plane in 3.1 seconds and running to 20 mph in 6 seconds and to 30 mph in 8.6 seconds.
