Yamaha 300hp DEC Outboard Engine F300UCB

Yamaha 300hp DEC Outboard Engine F300UCB – Reliability Reimagined

The Yamaha F300UCB DEC Outboard Engine stands as a flagship of power, precision, and trust. Over the years, Yamaha’s V6 4.2-liter outboards have earned a reputation among offshore anglers and commercial operators alike for their solid build and near-legendary dependability. Now, the Yamaha 300HP DEC F300UCB brings a new evolution to this already iconic platform—equipped with cutting-edge technology, a redesigned cowling, and integrated Digital Electric Steering (DES).

For those navigating offshore environments where the sea is as unpredictable as the wind, your engine needs to respond to every throttle input with sharp control and unwavering strength. That’s exactly what the F300UCB delivers.

A Legacy of Offshore Excellence

For more than a decade, Yamaha’s V6 outboards have dominated the offshore scene. Their track record is not just about power—it’s about trust. With a 96% reliability rate, they are among the most dependable V6 engines ever built.

Now refreshed with a new look, enhanced features, and advanced integration, the Yamaha 300HP DEC is more than an upgrade. It’s a game-changer.

Digital Precision and Clean Handling

The new Digital Electric Steering (DES) system completely eliminates the clutter of hydraulic hoses and fluid, delivering smoother and more accurate steering. This built-in steering system reduces maintenance and improves helm response, especially during low-speed maneuvers.

Combined with Command Link Digital Controls, the F300UCB offers instant and refined control over shifting and throttle—ideal for docking, fishing, or high-speed cruising.

Enhanced Features for Every Adventure

This outboard engine is more than just a workhorse. It’s engineered for comfort, convenience, and control.

Yamaha Saltwater Series II™ HP Prop

The redesigned prop boosts top speed performance by up to 2 mph in light applications. It’s optimized for saltwater use and features Yamaha’s Shift Dampener System (SDS®) for silent, vibration-free shifting.

TotalTilt™ Trim System

With the double-tap of a button, you can now fully tilt the engine up or down quickly. This simplifies trailering, storage, and access to shallow water zones.

Thrust Enhancing Reverse Exhaust

Maneuver with confidence. Yamaha’s clever exhaust rerouting ensures the propeller stays in clean water under 2500 RPM and during reverse gear, resulting in better grip and control near docks or while reversing to land a catch.

Premium Design for Form and Function

The Yamaha F300UCB sports a sleek new cowling available in Yamaha Gray or Pearlescent White, matching modern boat aesthetics. This new exterior isn’t just about looks—it incorporates a rerouted exhaust for improved reverse thrust and quieter operation.
