Yamaha 425hp XTO Offshore Outboard Engine XF425XSB

Yamaha 425hp XTO Offshore Outboard Engine XF425XSB – Extreme Power Meets Unrivaled Innovation

When it comes to offshore boating, power, reliability, and precision are paramount. Yamaha’s award-winning 425hp XTO Offshore Outboard Engine XF425XSB embodies these values, setting a new benchmark in marine propulsion. This engine is not just an outboard motor — it’s a fully integrated power system designed for serious boaters who demand the very best.

Cutting-Edge Technology for Offshore Excellence

The Yamaha XTO Offshore combines groundbreaking engineering with Yamaha’s decades-long expertise. At its heart is a massive 5.6-liter V8 four-stroke direct-injection powerhead. This advanced design delivers a robust 425 horsepower, making it one of the most powerful and fuel-efficient outboards in its class.

• Direct Injection: Up to 2900 PSI fuel pressure ensures efficient combustion, increased power, and improved fuel economy compared to traditional carbureted or port-injected engines.

• Compression Ratio: An impressive 12.2:1 compression ratio helps maximize output and efficiency, ideal for the high demands of offshore boating.

• Electric Power Steering: Integrated all-electric power steering delivers smooth, responsive control, reducing fatigue on long trips.

• Digital Electronic Controls: Precision throttle and shift control provide smoother acceleration and gear changes, enhancing overall driving experience.

Innovative Features Designed for Control and Durability

Yamaha designed the XF425XSB to withstand the harsh offshore environment while delivering superior control and comfort:

• Thrust-Enhancing Reverse Exhaust: Redirects exhaust away from the propeller at RPMs below 2,500, allowing for better maneuverability and precise low-speed control—critical when docking or navigating tight spaces.

• Pump Stop Power Tilt Limit: Prevents overrun by shutting off the tilt pump once the motor reaches its maximum tilt setting. This saves battery power and reduces noise during operation.

• Wide-Span Mounting System: Minimizes vibration through robust motor mounts spaced wide apart on the upper midsection. The long-span mounting system adds to engine stability and reduces stress on the boat transom.

• Phase Angle Control Charging System: Yamaha’s innovation award-winning charging system produces up to 96 amps of net charging power at idle from a single engine, supporting high electrical demands onboard. When used in multi-engine setups (up to quint configurations), it delivers up to 480 amps.
