Yamaha 425HP LXF425ESB XTO – DES V8 25in

Yamaha 425HP LXF425ESB XTO Offshore Counter 25in

The Yamaha 425HP LXF425ESB XTO Offshore is a specialized 5.6L V8 engine featuring counter-rotation and a 25-inch shaft, engineered for the port side of high-horsepower multi-engine arrays. This 32-valve DOHC powerhouse utilizes high-pressure direct injection to deliver unparalleled torque density and explosive thrust, specifically tuned to push the heaviest offshore hulls through demanding sea states. Its mechanical soul is defined by the integrated Digital Electric Steering (DES), which provides a clean, hose-free transom and a level of steering precision that was previously unattainable in this power class.

Focused on long-term operational durability, the LXF425ESB features Plasma Fusion cylinder walls for reduced friction and increased heat dissipation without the weight of traditional steel liners. The chassis is shielded by Yamaha’s multi-layered anti-corrosion system and massive sacrificial anodes to prevent galvanic wear in high-salinity environments. Ownership value is maximized by the industry-first ability to change gearcase lubricant while the vessel remains in the water. This unit includes a massive 90-amp alternator to power advanced navigational electronics, stabilizers, and high-demand onboard accessory loads.
