amaha F300UCB DEC: Elevating Offshore Excellence with Enhanced Features

Yamaha’s V6 4.2-liter outboards have stood the test of time as offshore favorites, initially drawing boaters in with their power, efficiency, and intelligent design. Over the years, these V6 4.2-liters have earned a reputation for something even more valuable offshore—reliability, boasting a legendary 96 percent reliability. Now, Yamaha’s trusty outboards are making waves with a fresh new look and integrated digital electric steering, adding to their responsiveness and reaffirming their status as trusted favorites in the marine world.

The Yamaha F300UCB DEC, already a reliable offshore favorite, has undergone enhancements, featuring a fresh new cowling design and rerouted exhaust for improved reverse thrust. It is available in Yamaha Gray or Pearlescent White, solidifying its position as a top choice offshore for years to come.

Key Features:

  1. Top Speed and Smooth Shifting:
    • Yamaha’s new Saltwater Series II™ HP Propeller can increase top-end speed by nearly 2 mph in lighter-weight applications.
    • Equipped with Yamaha’s patented Shift Dampener System (SDS®) for smoother, quieter shifting.
  2. Fast, Easy Tilting:
    • Introducing TotalTilt™, a new Yamaha exclusive that performs a quick, full trim up or down with a fast double-tap of a button, making trailering quick and easy.
  3. Powerful, Precise Maneuvering:
    • Thrust Enhancing Reverse Exhaust keeps exhaust bubbles away from the propeller below 2500 RPM and in reverse. This ensures the prop bites only clean water, resulting in outstanding reverse thrust and control—especially useful when backing down on fish and maneuvering around docks.
