Nitro resides at the apex of professional tournament bass boats and Kevin Van Dam has kept it in the spotlight with his many tournament wins. The new Z21 XL enhances its looks, fishability and competitive edge. With our setup, we ran this Nitro a tick over 70 mph at 6,000 rpm with a 23-pitch Mercury Fury propeller. That’s pretty swift with 500 pounds of boat testers and nearly 34 of a tank of fuel. Anglers looking for a complete package that performs at a competitive price will be hard pressed to ignore Nitro’s Z21 XL.
