See the story of how two durable In-Line Four engines passed the test of time—for over 6,800 hours.
Meet the lightweight, compact and powerful F200—the newest member of our In-Line Four family.
Progressive design makes the F200 compact and lightweight, but powerful enough to deliver impressive acceleration and midrange punch. In fact, the F200 In-Line Four has the best power-to-weight ratio in its class. Not only that, but it's available in both digital and mechanical models, making the F200 a perfect choice for repower applications with 26-inch mounting centers.
The In-Line Four family has been Yamaha’s bestseller, several years running. Here are just a few of the features that make these versatile dynamos so popular:
Variable camshaft timing and four tuned intake tracks increase low-and mid-range torque, boosting acceleration on the F200 and F150.
A 16-valve Double Overhead Cam 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, 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.
Twin counter balancer shafts on the F200 and F150 minimize engine vibration for a smooth, pleasant boating experience.
