Yamaha 300hp White DEC Outboard Engine F300UCB2 – Power, Control & Precision Offshore
The Yamaha F300UCB2 White DEC Outboard Engine redefines offshore boating performance. Featuring Yamaha’s legendary 4.2-liter V6 platform and integrated Digital Electric Steering (DES), it delivers powerful yet precise control whether you’re chasing big game fish or cruising blue waters. Known for 96% reliability, Yamaha’s offshore V6 outboards have earned the trust of serious boaters around the world.
Built for the Serious Offshore Boater
For over a decade, Yamaha’s V6 4.2L outboards have consistently set the standard for offshore reliability. The F300UCB2 takes that proven legacy further with new upgrades that matter on the water—like Thrust Enhancing Reverse Exhaust for better maneuverability and Yamaha’s TotalTilt™ for effortless trailering and positioning.
Whether you’re heading offshore or maneuvering around tight docks, the Yamaha 300HP White DEC outboard is engineered to deliver maximum performance, smooth control, and responsive feedback.
Performance Features That Lead the Industry
1. Saltwater Series II™ HP Prop with SDS®
This advanced propeller system boosts your top-end speed up to 2 mph in light-weight applications and integrates Yamaha’s Shift Dampener System (SDS®) for ultra-smooth gear shifts.
2. TotalTilt™ for Effortless Tilt Control
Yamaha’s exclusive TotalTilt™ allows you to perform a full tilt up or down with just a double-tap of a button, making trailering and on-water operation simpler than ever.
3. Thrust Enhancing Reverse Exhaust
The system routes exhaust bubbles away from the propeller below 2500 RPM in reverse, allowing the prop to bite clean water. This results in powerful, controlled reverse thrust when backing down fish or docking.
