Key Features & Benefits: Powering Your Journeys

Let’s explore the robust features and practical advantages that establish the F250XB as a premier choice.

Powerful 4.2L Big-Bore V6 for Reliable Output

At the very heart of the F250XB is a formidable 4.2L (4169cc) 60-degree V6 engine. This “big-bore” displacement is made possible through an advanced thermally applied plasma fusion process on the cylinder walls. This innovative process eliminates conventional steel cylinder sleeves. Instead, the cylinder walls are an impressive 60% harder than steel. Consequently, this allows for larger cylinder bores, meaning significantly more power and torque. Outer engine dimensions remain compact. This design also contributes to lighter weight, superior cooling, and reduced friction. All these factors enhance both performance and long-term reliability. Therefore, expect strong, consistent power whenever you need it.

Exceptional Fuel Efficiency for Extended Range

Despite its immense power, the F250XB boasts outstanding fuel efficiency. Its Precision Multi-Point Electronic Fuel Injection (EFI) system ensures precise fuel metering. It optimizes combustion for excellent economy. This intelligent system, combined with friction-reducing micro-textured cylinder walls, delivers superb fuel economy. It applies across the entire RPM range. Thus, you can extend your time on the water. Spend less time at the fuel pump.

High-Output Charging for All Onboard Systems

Modern boats rely heavily on electronic devices. The F250XB impressively produces up to 70 gross amps of charging power. This ample output reliably powers your growing array of onboard electronics. This includes multiple fish finders, navigation systems, and other accessories. Furthermore, this ensures all your critical systems remain fully operational throughout your longest trips.

Smooth, Quiet, and Comfortable Operation

Yamaha has meticulously engineered the F250XB for impressively smooth and quiet operation. Engine exhaust gases are strategically routed. They pass through a labyrinth of passages. Then, they exit via an idle exhaust relief outlet, reducing sound. The design minimizes vibration and noise. Therefore, you’ll experience less noise-related fatigue. Enjoy significantly more comfort on the water, even during extensive trips.

Built for Unwavering Durability and Convenient Maintenance

The F250XB is inherently built tough. It withstands the rigors of heavy use and harsh marine environments. Its advanced cowling drain system efficiently drains any water. This protects crucial internal components. Incoming air routes through a labyrinth of passages. These effectively trap and drain water, ensuring maximum reliability. Additionally, the outboard features Thrust Enhancing Reverse Exhaust (TERE). This keeps exhaust bubbles away from the propeller below 2500 RPM and in reverse. This means the prop bites clean water, resulting in outstanding reverse thrust and control, especially when backing down on fish or maneuvering in tight spaces.

For ultimate convenience, the F250XB includes Yamaha’s exclusive TotalTilt™ Feature. A swift double-tap of the trim button performs a full tilt up or down. This makes trailering and shallow water navigation incredibly quick. This feature is also handy for propeller changes or docking.
