V6 4.2 LITER

Digital: 300 hp, 250 hp, 225 hp
NEW Mechanical: 300 hp, 250 hp, 225 hp

Meet Yamaha’s award-winning V6 4.2-liter outboards. Fusing power, efficiency, speed and light weight, their intelligent design absolutely sets the standard for offshore performance. And now, you can add versatility to that list. With all V6 4.2L models—F300, F250 and F225—available in both mechanical and digital control, you can step up your power, without rebooting your rigging. Seventeen percent more fuel efficient at cruise RPM*, up to 73 pounds lighter than some competitors and more than 10 years of proven Yamaha reliability. There’s a reason why so many anglers won’t trust anything else a hundred miles out. Find a Demo Tour

REPOWER MEETS FLEXIBILITY

Our entire line of Offshore V6 4.2L outboards is compatible with either mechanical or digital controls. That gives you the freedom to increase your horsepower and your displacement without replacing your rigging.

Power & Performance

 
4.2 Liter Big Bore Displacement
4.2 Liter Big Bore Displacement

4.2 Liter Big Bore Displacement


Yamaha’s 4.2-liter V6 Offshore outboards feature plasma-fused sleeveless cylinder walls, which are 60 percent harder than steel. That means larger cylinder bores for increased displacement, resulting in more power and torque, without increasing outer cylinder dimensions. It also results in dramatically lighter weight and better cooling, and “micro-textured” cylinder walls that help decrease friction loss, and further increase performance and enhance reliability. 

Best-in-Class Fuel Efficiency
Best-in-Class Fuel Efficiency

Best-in-Class Fuel Efficiency


Our 4.2-liter V6’s are up to 17 percent more fuel efficient at 3500 RPM than other four-stroke V6's.* For maximum power and efficiency, electronically controlled throttle valves work in concert with Precision Multi-Point Fuel Injection to ensure a precise mix of air and fuel. In addition, six individual sensors constantly provide vital atmospheric and engine conditions to the Engine Control Module (ECM), which makes adjustments for performance.

Lightest Weight in Class
Lightest Weight in Class

Lightest Weight in Class


From the top of the cowling to the tip of the propeller shaft, every ounce of weight-savings has been realized for maximum performance without sacrificing durability. There’s even a new advanced polymer composite lower engine pan that lowers weight and increases corrosion resistance. The 4.2-liter V6's are up to 73 pounds lighter than other four strokes in their class, at 562 pounds (digitaL and 551 pounds (mechanical).

Throttle Response & Acceleration
Throttle Response & Acceleration

Throttle Response & Acceleration


Yamaha’s Variable Camshaft Timing system advances and retards the angle of the intake camshaft to dramatically increase power and throttle response in the low- and mid-RPM ranges. This feature helps Yamaha’s new 4.2-liter big-bore V6 outboards deliver awesome hole shot and mid-range acceleration. 

Cruising Speed
Cruising Speed

Cruising Speed


The Yamaha F300 is up to 19% faster at cruise RPM than other 300-hp four-stroke outboards.* Cruise RPM is where most offshore outboards are typically operated, meaning you get there faster, using less fuel, than competitive models.  *Testing conducted by Yamaha at Yamaha’s test facility on a Grady-White® 257 Advance, with each boat rigged for maximum performance.

Reliability & Durability

Reliability & Durability

Protection from the Elements


All Yamaha V6 4.2-liter outboards feature a proven cowling drain system, to easily and efficiently drain away any water that enters the cowling during normal engine operation. Incoming air is routed through a labyrinth of passages that trap and drain water before it enters the engine’s intake, for maximum reliability. 

Convenience & Control

Best-in-Class Charging Power

With up to 70 amps of total alternator output, our V6 4.2-liter outboards have over 29 percent more charging power than other V6 four strokes, and ample charging for an array of on-board electronic devices.
 

Precise and Convenient Trolling

Our Variable Trolling RPM Switch (VTS®)  allows you to adjust trolling speed from 600 ~ 1000 RPM, in 50-RPM increments, for consistent trolling speeds in any conditions.
 

More Information / Security

Command Link Plus® features a 6-inch high-contrast, multi-engine, LCD or an-all new 7-inch touchscreen display; digital electronic controls; key switches and start/stop panels; and more flexibility and information than ever. Its optional Y-COP® theft-deterrent system disables the ignition and fuel systems while docked.
 

Smooth Shifting

Our patented Shift Dampener System (SDS™) absorbs the resulting force of shifting gears, greatly reducing the noise commonly associated with shifting.
