White V6 Offshore Finish
The F350ESA2 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 ensure 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 at high speed with digital precision.
Integrated DES Technology
This 350HP outboard features Integrated Digital Electric Steering (DES) for a smooth and responsive boating experience without external hydraulic lines. This digital steering system provides a clean bilge while offering adjustable steering friction and precision for the captain. Professional anglers can enjoy effortless vessel command during long offshore tournament days without operator fatigue or mechanical lag.
35-Inch Ultra-Long Shaft
The F350ESA2 motor integrates an ultra-long 35-inch shaft length explicitly calibrated for deep-V offshore vessel transom dimensions. This specific lower unit immersion prevents propeller aeration in following seas while maintaining a secure grip on the water surface during turns. US offshore boaters gain improved steering authority and stable tracking during aggressive maneuvers in open sea conditions.
Digital Control DEC Interface
The F350ESA2 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 Helm Master EX for advanced vessel positioning and joystick control during technical maneuvers. Captains gain effortless control of multiple engine setups for a complete and modern helm solution on luxury offshore vessels.
Pro Maintenance Care
This Digital V6 engine is built with high-quality sacrificial anodes to prevent destructive galvanic corrosion daily in saltwater. Regular maintenance of the power trim and tilt system ensures smooth engine adjustments in harsh coastal environments. Pro Tip: Flush the internal cooling passages with fresh water after every launch to maintain cooling system integrity and prevent salt buildup.

Yamaha F350ESA2 350HP DEC Offshore Technical Guide
Field tests indicate the white Yamaha F350ESA2 consumes approximately 31.5 gallons per hour at full throttle for its 4.3L V6 configuration. This 35-inch ultra-long shaft DEC model utilizes precise electronic fuel injection to maintain EPA compliance and high-torque output. Observe the gallons per hour rate at 4500 RPM to find the most efficient cruising speed.
The white F350ESA2 incorporates oversized internal water passages and Yamaha’s ACP-221 paint system to protect the 35-inch shaft from salt crystallization. This protection adheres to ABYC guidelines for recreational marine use in demanding conditions. Regularly cleaning the sacrificial aluminum anode locations is essential for preserving the integrity of the standard rotation lower unit.
The 4.3L Yamaha F350ESA2 has an oil capacity of 6.7 US quarts when the filter is replaced during routine maintenance. Maintaining the FC-W engine oil capacity with high-quality lubricants is crucial for protecting the internal VCT (Variable Camshaft Timing) system. Ensure the engine is trimmed fully down before reading the dipstick.
Yamaha’s F350ESA2 provides 70 amps of alternator output to handle the requirements of DEC arrays and digital helm systems. You must utilize a battery with a minimum marine cranking amps rating of 800 MCA for reliable starting performance. All electrical installations must follow ABYC E-11 standards to ensure long-term system reliability.
The F350ESA2 performs best with a Saltwater Series II stainless steel propeller pitch chosen to match the hull\'s specific displacement and drag. Achieving a 5000-6000 RPM range at wide open throttle is necessary for engine longevity and speed. Test multiple pitch sizes if your boat fails to reach factory benchmarks.
