Balanced Power and Unrivaled Control for Demanding Offshore Adventures

The Yamaha LXF450XSA is engineered to complement a standard rotation (XF) outboard perfectly. Its left-hand (counter) rotation is vital for neutralizing steering torque. This provides a balanced and intuitive driving experience. Consequently, this configuration improves straight-line tracking. It also significantly reduces steering effort. Furthermore, it enhances precision during docking and tight turns, which is crucial for large boats.

Beyond its raw 450HP V8 might, the LXF450XSA offers an extraordinary level of integrated boat control. The integrated Digital Electric Steering (DES) provides smooth, ultra-responsive steering without external hydraulic lines. This simplifies rigging and enhances reliability. When combined with Yamaha’s Helm Master EX® system, boaters gain access to intuitive joystick control. They also get advanced autopilot features and innovative SetPoint™ modes. These collectively redefine the offshore experience. For instance, holding position over a fishing spot becomes effortless. The LXF450XSA’s design also incorporates subtle yet impactful aesthetic and performance enhancements, reflecting its premium status.

Key Features of the LXF450XSA: Engineered for Excellence

Explore the advanced technologies, robust engineering, and meticulous design details. These factors establish the Yamaha LXF450XSA as a leading choice for high-performance offshore applications.

Counter-Rotating (Left-Hand) Design

The “L” in LXF450XSA specifically denotes its counter-rotation. This is fundamental for multi-engine installations. It works in perfect harmony with a standard rotation outboard. This balances thrust and provides superior handling.

Direct Injection 5.6L V8 Engine

At the heart of the LXF450XSA is its powerful 5.6-liter, 32-valve V8 engine. It features Direct Fuel Injection. This sophisticated system atomizes fuel. It then delivers it directly into the combustion chamber under very high pressure. This maximizes power output. It also greatly improves fuel economy. Moreover, it ensures cleaner emissions across the entire RPM range.

Integrated Digital Electric Steering (DES)

Experience precise and effortless steering with a clean, uncluttered transom. The LXF450XSA features Digital Electric Steering (DES) integrated directly into the outboard’s bracket. This innovative design eliminates external hydraulic components. Consequently, rigging complexity is reduced. It also provides smooth, immediate steering response. This enhances control and reliability.

High-Output Phase Angle Control (PAC) Charging System

Power all your sophisticated onboard electronics with confidence. The LXF450XSA incorporates an advanced Phase Angle Control charging system. It delivers an outstanding 96 net amps at idle (102 gross amps). This robust output ensures that even with numerous demanding accessories, your batteries remain charged. For instance, gyro stabilizers, air conditioning, and premium sound systems run flawlessly, even at low RPMs.

Standard 25-inch Shaft Length

The “X” in LXF450XSA indicates its versatile 25-inch (635mm) shaft length. This “X-long” shaft is ideal for many offshore boats. It ensures optimal propeller depth. This contributes to efficiency and performance in various conditions.

Thrust Enhancing Reverse Exhaust (TERE)

Achieve exceptional control and precision in reverse. Yamaha’s TERE system cleverly diverts exhaust gases away from the propeller. This occurs at low RPMs (below 2,500). As a result, the propeller bites clean water. This significantly increases reverse thrust. It also greatly improves maneuverability for tasks like precise docking or backing down on fish.

TotalTilt™ for Effortless Operation

Simplify engine tilting with Yamaha’s exclusive TotalTilt™ feature. A quick double-tap of the trim/tilt button initiates a full tilt up or down. This makes trailering, mooring, and prop inspection quick and effortless. (Note: TotalTilt™ may be factory-defaulted to “OFF” for user preference, allowing activation as desired.)

Robust Durability and Service-Friendly Design

Built to withstand the harshest marine environments, the LXF450XSA features heavy-duty construction. It has a multi-part cowling for easy access during maintenance. Innovative features, such as the in-water gear lube change system, further simplify routine service. This ensures maximum uptime and peace of mind.
