The brand behind every reliable engine
Reliable coverage beyond your warranty
There’s a good reason why the legendary Yamaha F150 is the best-selling 150-horsepower four stroke of all time. Powerful, light, nimble and compact, boaters know that its proven reliability is unmatched for everything from pontoons to flats boats to deep-V hulls. That record of performance spawned a remarkable family line that continues with the F175 and F200. Now, more boaters can enjoy Yamaha’s technologically advanced I-4 line than ever before. Whether your rigging is digital or mechanical, the entire lineup is compatible with your control preference. It’s just one of the ways the I-4 line keeps getting better and better, year after year.
Now, the F200, F175 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 the these model are the same as those on our HPDI® two strokes, making it easy for you to step up or down in horses without having to replace your rigging.
A proven 16-valve DOHC In-Line design, with four valves per cylinder maximizes efficiency and power. It also streamlines design, giving the F200 class-leading power-to-weight and making the F175 nearly 30 pounds lighter than its closest 1.7-liter competitor.
Precision Multi-Point Electronic Fuel Injection and long-track intake system combine to maximize power and fuel efficiency across the line of In-Line Fours (except F150 Mechanical).
Four valves per cylinder maximizes combustion efficiency in a way that no two stroke can, delivering the utmost in clean, quiet power and performance.
A 10mm Offset Crankshaft allows for larger intake volume design. Four tuned intake tubes boost torque in low and mid-speed ranges for quick acceleration.
The Composite Intake Manifold is a lightweight, compact design, making these engines very versatile. Long Tube Intake Tracks are tuned to increase airflow, boosting low-end and midrange torque. This means a more powerful hole shot and increased acceleration. Even with all this responsive power, an air silencer box and surge tank reduce air intake noise and air turbulence for smoother operation.
Combined with our proprietary alloy (YDC-30), our exclusive Phaze Five™ electro-deposited, anti-corrosive paint system provides a tough, five-layer barrier against corrosion. This protection is standard on all Yamaha In-Line Four-Stroke engines.
26-inch mounting centers and a bolt pattern that matches previous two strokes make In-Line Fours flexible for most repowers
With up to 50-amp alternators, our In-Line Fours provide plenty of power for a range of electronics, which comes handy, now that they're all compatible with digital controls
Extended Trim Range delivers better acceleration-to-plane and top-end speed. The tilt range is a full 70° for tilting the engine above the waterline.
A Freshwater Flush Device allows you to flush the engine without running it, for added convenience and extended engine life.
Yamaha's Shift Dampener System greatly reduces the noise commonly associated with shifting gears. Using a special design and components, much of the force of shifting is absorbed, resulting in far quieter and smoother operation.
Yamaha In-Line Four
The lightest DOHC outboard in its class, this I-4 is the perfect, lightweight 200-hp solution for small- to medium-size boats.
The F175 is 30 pounds lighter than its closest 1.7-liter competitor, but it still delivers breathtaking acceleration, midrange punch and impressively smooth performance. It’s compatible with either mechanical controls or digital controls.
The F150 is one that started it all and it’s more popular than ever. Powerful, light and compact, it’s now mechanical or digital compatible, making it available to more boaters than ever before.
† Weight refers to shortest shaft length, and is measured without motor oil, gearcase oil and propeller (except models 25 hp and under, which include a standard propeller). All Jet model weights include the jet pump assembly (weight estimated).
