Suzuki's High-Thrust 9.9 horsepower 4-stroke was specially designed for slammin' salmon and whackin' walleye. The new Batteryless EFI powerhead with an integrated power tilt system makes raising and lowering Suzuki's DF9.9TH High Thrust a breeze. With 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. Built for the big job, with forged aluminum connecting rods, a one-piece forged crankshaft and a low oil pressure warning system. A large hub design even reduces cavitation in reverse. The DF9.9BTH High Thrust outboard is one "thrust-worthy" fishing comparison.
