Yamaha LF250XSB2 250HP in White DEC 25″ Shaft Counter Rotation

Yamaha LF250XSB2 250HP White Integrated

The Yamaha LF250XSB2 pairs a 4.2L 24-valve DOHC V6 with counter-rotation gearing, finished in Pearlescent White at 529 lbs dry — a strong power-to-weight ratio for premium multi-engine offshore vessels. The 25-inch shaft is built into Mulmarine’s reliable marine propulsion systems lineup for boats that need neutralized steering torque and stable hydrodynamic tracking at high speed.

Peak output holds through the 5000-6000 RPM band, using Integrated Digital Electric Steering (DES) and Helm Master EX compatibility. The 1.75:1 gear ratio converts that engine’s energy into torque that gets a hull planing without hesitation. US offshore boaters lean on this Japan-engineered platform for its reliability and smooth digital shifting in twin-engine setups.

White V6 Integrated Precision

The LF250XSB2’s Pearlescent White finish matches the aesthetic on luxury center consoles and offshore cruisers. The 24-valve V6 configuration maximizes air intake for rapid, responsive hole-shot acceleration under load. Owners get smooth power delivery and reduced vibration cruising through coastal chop with balanced torque and digital precision.

Integrated DES Technology

This 250HP outboard runs Integrated Digital Electric Steering (DES) for a smooth, responsive feel at the helm without external hydraulic lines. The digital system keeps the bilge clean while giving the operator adjustable steering friction. Anglers and luxury cruiser owners get to run long offshore days without operator fatigue or mechanical lag during docking maneuvers.

Routine Maintenance Care

This digital V6 runs high-quality sacrificial anodes to keep galvanic corrosion in check in saltwater coastal environments. Regular attention to the power trim and tilt system, along with the cooling passages, keeps the engine running smoothly. Pro Tip: flush the internal cooling passages with fresh water after every launch to maintain cooling system integrity and prevent internal salt accumulation.
