Yamaha 450HP LXF450XSA2 White XTO Offshore Counter Rotation – 25″ Shaft, Digital Controls

Yamaha LXF450XSA2 450HP Outboard Motor

The Yamaha 450HP LXF450XSA2 provides a counter-rotation solution for propeller ventilation and torque steer in multi-engine configurations while resisting UV-induced surface degradation. This left-hand rotation gearcase is engineered for maximum tracking stability and balanced handling across heavy fiberglass offshore hulls. Utilizing a high-torque 5.6L V8 powerhead, the system leverages a 1.79:1 gear ratio to eliminate performance lag during aggressive acceleration. Hydrodynamic optimization of the white lower unit housing ensures clean water flow to the blades, improving propeller bite and reducing cavitation during offshore transit.

Yamaha 450HP LXF450XSA2 engineering complies with EPA Tier 3 and CARB 3-Star standards for environmental duty in regulated coastal waters. Specialized internal cooling galleries on this unit utilize pressurized freshwater flushing to mitigate saltwater mineral deposits and galvanic corrosion within the block. High output 90-amp alternators maintain battery health and sustain complex digital flight-by-wire controls during intense marine propulsion cycles. This system utilizes a three-stage cooling process to regulate internal component temperature even when the engine operates at wide open throttle for extended periods.
