Yamaha LF250ESB2 250HP – DEC 35″ Shaft Counter Rotation in White

Yamaha LF250ESB2 250HP White Counter

The Yamaha LF250ESB2 pairs a 4.2L 24-valve DOHC V6 with counter-rotation gearing, finished in Pearlescent White at 580 lbs dry — a strong power-to-weight ratio for premium multi-engine vessels. The 35-inch ultra-long shaft is built into Mulmarine’s reliable marine propulsion systems lineup for boats that need neutralized steering torque and stable thrust at high speed.

Peak output holds through the 5000-6000 RPM band, using Digital Electronic Control (DEC) and a precision multi-point EFI system. 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 Offshore Finish

The LF250ESB2’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. 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 get to run long offshore days without operator fatigue or mechanical lag.

35-Inch Ultra-Long Shaft

The 35-inch shaft is calibrated for deep-V vessel transom dimensions, keeping the prop from aerating in following seas while holding a secure grip on the water during turns. US boaters get better steering authority and stable tracking on oceanic transits.

Helm Master EX Integration

This 250HP outboard is fully compatible with Yamaha Helm Master EX for advanced positioning and joystick control at the helm, allowing precise movement in tight quarters and automated fishing patterns. Captains can manage multiple outboards through a complete modern helm setup.

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 protect against internal salt accumulation.
