Yamaha 350HP LF350ESA2 White DEC Counter Rotation – 35″ Shaft, Digital Electronic Controls

Yamaha LF350ESA2 350HP Outboard Motor

To address the specific requirements of deep-transom mounting and counter-rotation torque the Yamaha 350HP LF350ESA2 White DEC utilizes an ultra-long 35-inch shaft paired with a V6 powerhead architecture. This model optimizes a 4.3L displacement engine to provide the balanced thrust necessary for large multi-engine offshore vessels. The integrated gear ratio is engineered to handle massive propeller loads ensuring hydrodynamic efficiency across heavy hull configurations. Precise Digital Electronic Controls manage the power curve to eliminate performance lag and provide smooth throttle response during aggressive offshore navigation.

Maintaining the structural integrity of this marine propulsion system while complying with EPA Tier 3 standards ensures mariners experience peak reliability during long-range transit. The cooling system features pressurized freshwater flushing and YDC-30 alloy construction to mitigate the effects of saltwater corrosion and mineral deposits. High output alternators deliver the necessary current to sustain modern digital flight-by-wire controls and complex navigational electronics without battery depletion. This thermal management logic regulates internal component temperatures even when the engine is pushed to its absolute mechanical limits in tropical environments.
