The Shark Z71 is the most powerful ice auger in the world. It features a 71cc Viper Two-Cycle engine specially designed for ice augers. With high torque and 9000 engine RPM, you'll have a Viper engine that overpowers the competition, but remains easy to start and operate. The Shark Z71 has the industry-first Hypercoil recoil with technology that reduces required pulling force by up to 62%, resulting in easier starts. It also features industry-first aluminum handlebars designed with 45 degree rubber-coated grips that allow ideal wrist motion when drilling a hole. It is quick and easy to control so you'll spend less time drilling and more time fishing. Includes primer button for quick response starting, see-through gas tank for easy gas level detection, and a Muffler guard to protect you from hot areas. From top to bottom, the Shark Z71 has the strength you need on the ice.
