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

Yamaha LF350USA2 350HP White Counter

The Yamaha LF350USA2 350HP outboard motor represents a high-output luxury offshore propulsion, featuring an advanced high-displacement 4.3L V6 DOHC 24-valve engine architecture in Pearlescent White. This powerhead maintains a dry weight of 553 lbs to helps support an high-pressure power-to-weight ratio for premium multi-engine vessels requiring balanced thrust. Its 30-inch ultra-long shaft and counter-rotation gearcase are specifically designed for versatile marine outboard solutions requiring neutralized steering torque and a sophisticated aesthetic match during long-distance oceanic transits.

The recommended full-throttle operating range for the LF350USA2 350HP is a wide 5000-6000 full-throttle RPM range using Integrated Digital Electric Steering (DES) and Digital Electronic Control (DEC). The specialized 1.75:1 gear ratio effectively translates the V6 energy into torque for rapid hull planing without hesitation. US offshore boaters consistently depend on this Japanese-engineered platform for its reliable operation and the sleek aesthetic of a white offshore power plant.

White V6 Aesthetic Precision

The LF350USA2 features a stunning Pearlescent White finish to provide a high-end aesthetic match for luxury center consoles and high-performance hulls. Its robust 24-valve V6 configuration maximizes air intake to helps support rapid and responsive hole-shot acceleration under various loads. Luxury boat owners experience smooth power delivery and reduced vibration when cruising through technical coastal waterways with digital precision and balanced torque.

Integrated DES Steering

This 350HP outboard features Integrated Digital Electric Steering (DES) to provide a smooth and responsive boating experience without external hydraulic lines. This digital system provides a clean bilge while offering adjustable steering friction and precision for the captain. Professional anglers and luxury cruiser owners can enjoy vessel command during long offshore days without operator fatigue or mechanical lag during docking maneuvers.

Ultra-Long Shaft Performance

The LF350USA2 motor integrates an ultra-long 30-inch shaft length explicitly calibrated for specialized deep-V vessel transom dimensions. This specific lower unit immersion prevents propeller aeration in following seas while maintaining a secure grip on the water surface during maneuvers. US offshore This can provide improved steering authority and stable tracking during strong maneuvers in open sea conditions during oceanic transits.

Helm Master EX Integration

The 350HP outboard is fully compatible with Yamaha Helm Master EX for advanced vessel positioning and joystick control at the helm. This system allows for precise movement in tight quarters and automated fishing patterns for serious pelagic anglers. Captains can easily manage multiple outboards and integrate with digital displays for a complete and modern luxury offshore helm solution with minimal effort.

Precision EFI Induction

This 4-Stroke 350HP engine incorporates a Precision EFI system to optimize fuel atomization for maximum efficiency in varying maritime climates. Digital engine management helps support smooth throttle response and consistent starting power even in offshore temperatures. You achieve outstanding fuel economy while exploring remote offshore sections far from local marina fuel docks during high-speed transits.

Routine Maintenance Care

This Digital V6 engine is built with high-quality sacrificial anodes to prevent destructive galvanic corrosion daily in saltwater coastal environments. Regular maintenance of the power trim and tilt system and cooling passages helps support smooth engine operation in harsh conditions.Maintenance note: Follow the manufacturer’s service procedures and lubrication specifications for the engine and gearcase.
