Yamaha 450HP LXF450XSA XTO Offshore Counter Rotation Outboard, 25″ Shaft, Digital Control

Yamaha LXF450XSA 450HP Outboard Motor

The Yamaha 450HP LXF450XSA provides the necessary counter-rotation solution to eliminate propeller ventilation and torque steer in multi-engine offshore center console configurations. This left-hand rotation gearcase is engineered for maximum tracking stability and balanced handling across heavy fiberglass hulls. Utilizing a high-torque 5.6L V8 displacement, the system removes the performance lag typically associated with large-scale maritime vessels. Hydrodynamic optimization of the lower unit housing ensures clean water flow to the blades, improving propeller bite and reducing cavitation during aggressive mid-range throttle adjustments.

Yamaha 450HP LXF450XSA maintains EPA Tier 3 compliance to allow operation in restricted waters while providing the massive 450HP necessary for offshore reliability. Engineering focus on longevity includes pressurized freshwater flushing ports that effectively clear salt deposits from the internal engine block and cylinder heads. The electrical system features high-output charging capabilities to sustain complex digital flight-by-wire controls and offshore GPS systems. This robust thermal architecture prevents component fatigue during wide-open throttle operation in high-ambient temperature marine environments across the globe.
