I-4 Four Strokes

There’s a good reason why the legendary Yamaha F150 has enjoyed over a decade of unrivaled popularity. Powerful, light, nimble and compact, boaters know that its proven reliability is unmatched for everything from pontoons to flats boats to deep-V hulls. In fact, its versatile technology inspired the F200 and has served as the reliable foundation for remarkable advancements for both models. Whether your rigging is digital or mechanical, the entire lineup is compatible with your control preference. Plus, new integrated steering lets boaters hit the water with responsive performance, a cleaner bilge and more space on the boat for storage and comfort. Add in the sleek, modern cowling design and digital models now available in pearlescent white, and the I-4s just keep getting better and better, year after year.

COMPATIBLE CONTROLS FOR EVERY PLATFORM

The F200 and F150 are available with either digital or mechanical controls and even our next generation boat control system Helm Master® EX. In addition, the 26-inch mounting centers and bolt pattern on these models are the same as those on previous two-stroke models, making it easy for you to step up or down in horses without having to replace your rigging.
