Suzuki's new-for-2008 High-Thrust 9.9 horsepower 4-stroke was specially designed for slammin' salmon and whackin' walleye. New power tilt system makes raising and lowering Suzuki's DF9.9 High Thrust a breeze. If the fish aren't biting, pick up and run to the next hot spot. When you get there, plenty of torque, a high-thrust propeller and a 2.08:1 gear ratio deliver efficient and reliable low-speed trolling for a range of heavy fishing boats.
