Suzuki offers four-stroke power with the DF15. This compact, clean-running outboard is perfect for a wide variety of uses. And it's easy on fuel, going up to 50% farther on a tank of gas than comparable two-stroke models. Suzuki engineers designed this compact four-stroke engine to respond smoothly throughout the power curve, without the uneven throttle response you might find with other outboards. This is the engine of choice for boating and fishing magazine writers nationwide.
