Yamaha 425HP XF425XSB2 XTO Offshore White 25in

The Yamaha 425HP XF425XSB2 XTO Offshore is a technologically advanced 5.6L V8 featuring a 25-inch shaft in a premium Pearlescent White finish. As a second-generation “B” model, it features refined internals and enhanced reliability for the most demanding offshore applications. The 32-valve DOHC architecture focuses on structural integrity and power-to-weight optimization, utilizing Plasma Fusion cylinder liners to reduce internal friction. The integration of Digital Electric Steering (DES) ensures a clutter-free transom, making it an ideal choice for high-end center console fishing machines.

Focused on superior operational efficiency, the XF425XSB2 utilizes direct fuel injection and a 12.2:1 compression ratio to maximize energy output and fuel economy across the power band. The motor is protected by specialized anodic coatings and Yamaha’s multi-layered anti-corrosion system to combat the rigors of high-salinity marine environments. Ownership is simplified by the on-water gearcase oil change system and a front-mounted freshwater flush port. This model provides an industry-leading 90-amp alternator, ensuring a stable energy supply for multiple navigational displays and modern shipboard accessory loads.
