FOR THOSE WHO KNOW A GOOD TIME—WHEN THEY DRIVE IT.
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.
Variable camshaft timing and four tuned intake tracks increase low-and mid-range torque, boosting acceleration on the F200.
16-valve direct drive DOHC maximizes power by using four valves per cylinder, eliminating rocker arms and their adjustments and increasing air supply and volumetric efficiency for better performance on the F200, F175, F150 and F115.
Our In-Line Four family features electronic fuel injection controlled by the Engine Control Module. It continually adjusts the fuel/air mix to properly match engine load and speed.
Counterbalancing technology on the F200, F175, F150 and F115 minimize engine vibration for a smooth ride.
