Yamaha LF350ESA2 350HP – DEC 35″ Shaft Counter Rotation in White

Yamaha LF350ESA2 350HP White Counter

The Yamaha LF350ESA2 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 580 lbs to helps support a high-pressure power-to-weight ratio for premium multi-engine vessels. Its 35-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 LF350ESA2 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 in high-transom setups.

White V6 Performance Excellence

The LF350ESA2 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 Technology

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 Propulsion

The LF350ESA2 motor integrates an ultra-long 35-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.

Digital DEC Command Interface

The 350HP outboard utilizes Digital Electronic Control (DEC) to provide a smooth and cable-free throttle and shifting experience at the helm. This system is fully compatible with modern offshore rigging for advanced vessel positioning and synchronization in multi-engine setups. Captains gain control of multiple engine configurations for a complete and modern helm solution on luxury offshore vessels with digital accuracy.

Counter-Rotation Precision

The LF350ESA2 features a specialized counter-rotation gearcase that spins the propeller in a left-hand direction to neutralize torque pull. When paired with a standard rotation motor, this configuration helps support the vessel tracks straight and true with minimal steering effort from the captain. Boaters experience significantly improved stability and reduced operator fatigue during long oceanic crossings in following seas.

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.Pro Tip:Flush the internal cooling passages with fresh water after every launch to maintain cooling system integrity and prevent internal salt accumulation.
