Yamaha LF350USA2 350HP – DEC 30″ Shaft Counter Rotation in White

Yamaha LF350USA2 350HP White Counter

The Yamaha LF350USA2 350HP runs a high-displacement 4.3L V6 DOHC 24-valve engine, finished in Pearlescent White at a 553 lbs dry weight — a strong power-to-weight ratio for premium multi-engine vessels needing balanced thrust. The 30-inch ultra-long shaft and counter-rotation gearcase are built into Mulmarine’s versatile marine outboard solutions lineup for boats needing neutralized steering torque with a matching white finish.

Peak output holds through a 5000-6000 RPM full-throttle band, using Integrated Digital Electric Steering (DES) and Digital Electronic Control (DEC) together. The 1.75:1 gear ratio takes that V6’s energy and turns it into torque that gets a loaded hull planing without hesitation. US offshore boaters lean on this Japan-engineered platform for its reliability record and clean white finish.

• Integrated Digital Electric Steering (DES) delivers effortless handling and precise control at any speed.
• Digital Electronic Control (DEC) with Helm Master EX compatibility keeps helm management smooth.
• The 50-70 Amp alternator output keeps navigation radar and digital sonar powered.
• Coverage comes from a limited 3-year factory warranty and Japanese build standards.

White V6 Aesthetic Precision

The LF350USA2’s Pearlescent White finish matches the aesthetic on luxury center consoles and high-performance hulls. 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 technical coastal waterways with balanced torque.

Integrated DES Steering

This 350HP 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 and precision. Anglers and luxury cruiser owners get to run long offshore days without the fatigue or mechanical lag that comes with docking maneuvers.

Ultra-Long Shaft Performance

The LF350USA2’s ultra-long 30-inch shaft is calibrated for deep-V vessel transom dimensions found on large center consoles specifically. That immersion depth keeps the propeller from aerating in following seas while holding a secure grip on the water during maneuvers. US boaters get better steering authority and more stable tracking on long oceanic transits.

Helm Master EX Integration

This 350HP outboard is fully compatible with Yamaha Helm Master EX for advanced positioning and joystick control at the helm. That system allows precise movement in tight quarters plus automated fishing patterns for serious pelagic anglers. Captains can manage multiple outboards and tie into digital displays for a complete modern luxury offshore helm setup.

Precision EFI Induction

This 350HP four-stroke runs a Precision EFI system that optimizes fuel atomization for efficiency across varying maritime climates. Digital engine management keeps throttle response smooth and starting power consistent even in extreme temperatures. You get strong fuel economy exploring remote offshore sections far from the nearest marina during high-speed transits.

Routine Maintenance Care

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