Yamaha LF250XB 250HP V6 Counter 25″ Shaft Outboard Motor

Yamaha 250HP LF250XB V6 Counter 25in Shaft

Designed for traditional twin-engine repowers, the Yamaha 250HP LF250XB is a specialized 4.2L V6 outboard featuring counter-rotation and a 25-inch shaft. This model acts as the port-side counterbalance in a mechanical control array, neutralizing propeller torque to provide stable tracking and high-speed stability for large coastal fishing boats. The 4166cc DOHC architecture focuses on torque density and hydrodynamic efficiency, utilizing Plasma Fusion cylinder walls to reduce weight and internal friction while delivering the massive displacement necessary for heavy offshore loads.

Refined for high-performance efficiency, the LF250XB utilizes Multi-Point Precision EFI and Variable Camshaft Timing (VCT) to optimize fuel consumption and torque output. The motor is treated with specialized anti-corrosion coatings and marine-grade alloys to defend against oxidation in high-salinity zones. Maintenance effort is reduced by the 100-hour service schedule and conveniently located freshwater flush ports. This unit features a high-output 50-amp alternator, providing a stable charging system for multiple battery banks, navigational safety equipment, and high-demand onboard accessory loads during offshore transits.
