Key Features of Twin Yamaha 300hp DEC Outboards

Yamaha’s V6 4.2-liter outboards have long been offshore favorites, and the F300UCB and LF300UCB models continue to impress with innovative design improvements:

• Top Speed & Smooth Shifting: Equipped with Yamaha’s Saltwater Series II™ HP Propeller, these engines can increase top-end speed by nearly 2 mph in lighter-weight applications. The patented Shift Dampener System (SDS®) ensures smooth, quiet shifting.

• Fast, Easy Tilting: Yamaha’s exclusive TotalTilt™ allows full trim adjustments with a simple double-tap of a button. Trailering or raising the engines completely out of the water has never been easier.

• Powerful, Precise Maneuvering: Thrust Enhancing Reverse Exhaust channels bubbles away from the propeller, improving reverse thrust and control—critical when docking or fishing.

• Stylish & Durable Design: Fresh cowling design with rerouted exhaust, available in Yamaha Gray or Pearlescent White, enhances both aesthetics and performance.

• Integrated Digital Steering: The engines feature command link controls with remote hydraulic steering, providing responsive, intuitive handling for challenging offshore conditions.
