Overview
Built for the water you run
Yamaha F300USB—300hp V6 with digital electronic controls on a 30″ shaft. A workhorse single or twin primary for bay and offshore boats that want DEC responsiveness without jumping to 350+.
- Top Speed and Smooth Shifting — Yamaha’s new Saltwater Series II™ HP Propeller can boost top-end speed up by nearly 2 mph in lighter-weight applications. It’s also equipped with Yamaha’s patented Shift Dampener System (SDS ® ) for smoother, quieter shifting.
- Fast, Easy Tilting — A new, Yamaha exclusive, TotalTilt™ performs a quick, full trim up or down with the fast, double-tap of a button. This makes trailering quick and easy and is handy when a complete up or down tilt is needed.
- Powerful, Precise Maneuvering — Thrust Enhancing Reverse Exhaust keeps exhaust bubbles away from the propeller below 2500 RPM and when in reverse. This means the prop bites only clean water, which results in outstanding reverse thrust and control—especially when backing down on fish and when maneuvering around docks.
Full technical notes
Yamaha’s award-winning V6 4.2-liter outboards have been offshore favorites for more than a decade. Initially, boaters were attracted to their power, efficiency and intelligent design. After years of proven performance, our V6 4.2-liters have become known for something perhaps even more valuable offshore—reliability.
In fact, with legendary 96 percent reliability,** they’re one of the most trusted V6’s offshore. Well, now these trusty outboards are turning heads again, with a fresh new look and new, integrated digital electric steering—making them even more responsive. Our V6 Offshore outboards have proven once again that even a trusted favorite can take an exciting turn.
Yamaha’s F300 is a reliable, offshore favorite—and it’s only getting better. It now features a fresh, new cowling design and rerouted exhaust for enhanced reverse thrust and is available in Yamaha Gray or Pearlescent White. It’s destined to be a top choice offshore for years to come.
