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. That impressive resume now includes the option of a 35-inch shaft and the choice of colors for the F300 DEC model – available in new pearlescent white, as well as signature Yamaha gray.F300 testing conducted by Yamaha at Yamaha’s test facility on a Grady-White® 257 Advance, with each boat rigged for maximum performance. 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.Testing conducted by Yamaha at Yamaha’s test facility on a Grady-White® 257 Advance, with each boat rigged for maximum performance. 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.
