Yamaha Outboards 250HP | LF250XB: Precision Counter-Rotation Power

Discover balanced performance and unwavering reliability with the Yamaha LF250XB outboard motor. This 250HP V6 4-stroke engine is the counter-rotation (left-hand rotation) counterpart to the F250XB. It’s engineered for multi-engine installations. It delivers a potent blend of synchronized power, remarkable fuel efficiency, and Yamaha’s legendary durability. Consequently, it’s an excellent choice for offshore fishing boats, larger center consoles, and family cruisers that require a 25-inch shaft and dual-engine setup for superior control and minimized torque steer.

Why the Yamaha LF250XB is Essential for Twin-Engine Setups

The Yamaha LF250XB is specifically designed to work in tandem with a standard rotation (F250XB) outboard. This counter-rotating configuration eliminates torque steer, improves steering control, and enhances overall boat stability. It’s a critical component for optimizing the performance and handling of twin-engine vessels. Indeed, its robust design ensures consistent, quiet operation, even under heavy loads.

Key Features & Benefits: Powering Your Twin-Engine Command

Let’s explore the robust features and practical advantages that establish the LF250XB as a premier choice for multi-outboard installations.

Powerful 4.2L Big-Bore V6 for Reliable Output

At the very heart of the LF250XB 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.

Precision Counter-Rotation for Enhanced Control

The primary advantage of the LF250XB is its left-hand (counter-rotation) propeller spin. When paired with a standard right-hand rotation F250XB, the opposing propeller forces cancel each other out. This significantly reduces steering effort and torque steer. It provides a more balanced and comfortable ride. Furthermore, it improves maneuverability, especially at low speeds and in reverse.

Exceptional Fuel Efficiency for Extended Range

Despite its immense power, the LF250XB 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 LF250XB 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 LF250XB 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 LF250XB 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 LF250XB 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.
