You’re here to wake up the water. Count on Yamaha’s reliable In-Line four strokes to power the fun. Our in-line four-cylinder designs and electronic fuel injection make these babies strong, nimble, compact and light weight. In other words, they’re up for anything, making them the perfect power for cruising, skiing and sport fishing on flats, decks and offshore boats, and pontoons or deep-V hulls. We’ve even freshened up the best-selling 150-horsepower four-stroke outboard by refining the cowling drainage and adding a tough 8-tooth “dog clutch” to make this dependable workhouse even more reliable.
