Yamaha F350ESA Outboard: The Pinnacle of Offshore Power with a 35-inch Shaft
Experience the absolute pinnacle of offshore performance with the all-new Yamaha F350ESA outboard. This groundbreaking 350-horsepower V6 engine redefines big power in a remarkably lightweight package. Precisely engineered for exhilarating speed and immense torque, the F350ESA is the ideal choice for a wide range of large offshore vessels. Its standard (clockwise) rotation makes it a versatile primary power unit, seamlessly integrating with counter-rotating models in multi-engine applications.
The F350ESA is built around a newly upgraded 4.3-liter V6 engine block. This ensures not only incredible durability but also class-leading fuel efficiency. With an extra-extra-long 35-inch (E) shaft length, this model is perfectly suited for boats with exceptionally high transoms, typically found on specialized, large offshore super consoles or custom applications requiring the deepest possible propeller immersion. This provides superior performance for the most demanding offshore conditions. The “ESA” designation signifies its state-of-the-art integrated Digital Electric Steering (DES) and full Helm Master EX® compatibility. This integration represents Yamaha’s latest advancements in intelligent boat control, offering an unparalleled level of precision and convenience. This model thus establishes a truly dominant and sophisticated presence on your transom.
Unmatched Power, Efficiency, and Integrated Control for Ultimate Offshore Adventures
The Yamaha F350ESA represents a significant leap forward in outboard technology. Its new 4.3L V6 platform delivers a superior power-to-weight ratio. This makes it over 65 pounds lighter than its closest competitor while still producing formidable 350 horsepower. This lighter weight translates to improved boat performance and efficiency. It also broadens the range of boats it can power.
Beyond its impressive power, the F350ESA offers extraordinary integrated boat control. The integrated Digital Electric Steering (DES) eliminates external steering pumps and hydraulic lines. This results in a cleaner, uncluttered transom and exceptionally precise steering. When paired with Yamaha’s Helm Master EX® system, boaters gain access to intuitive joystick control, advanced autopilot features, and innovative SetPoint™ modes. These collectively redefine the offshore experience. For instance, maintaining position over a fishing spot becomes remarkably easy. The F350ESA also features modern aesthetic and functional refinements, ensuring your boat not only performs exceptionally but also commands attention.
Key Features of the F350ESA: Engineered for the Demands of the Open Water
Explore the advanced technologies, robust engineering, and meticulous design details. These factors establish the Yamaha F350ESA as a premier choice for high-performance offshore applications.
New 4.3L V6 Engine Block
The heart of the F350ESA is its entirely new 4.3-liter V6 engine block. This is a significant upgrade from previous 350hp models. It features larger intake and exhaust valves. It also boasts an 81mm electronic throttle valve. This boosts airflow and combustion. Consequently, it delivers robust torque across all RPMs.
Integrated Digital Electric Steering (DES)
Experience precise and effortless steering. Benefit from a clean, uncluttered transom. The F350ESA features Digital Electric Steering (DES) integrated directly into the outboard’s bracket. This innovative design eliminates external hydraulic components. Consequently, rigging complexity is reduced. It also provides smooth, immediate steering response. This enhances control and reliability.
Exceptional Power-to-Weight Ratio
Weighing in at approximately 653 pounds (296 kg), the F350ESA boasts the best power-to-weight ratio in its class. This lighter design significantly improves boat performance. It also enhances fuel economy. Furthermore, it expands the range of suitable boat applications.
High-Output Charging System
Power all your sophisticated onboard electronics with unwavering confidence. The F350ESA’s advanced charging system produces up to 70 gross amps. More importantly, it delivers over 30 net amps at idle. This is nearly double the output of comparable outboards. This robust power ensures your batteries remain charged, even with multiple demanding accessories.
35-inch (E) Shaft Length
The “E” in F350ESA indicates its specific 35-inch (894mm) shaft length. This “extra-extra-long” shaft is designed for boats with exceptionally high transoms. These are commonly found on very large offshore vessels or specialized applications. It ensures optimal propeller depth and performance.
Thrust Enhancing Reverse Exhaust (TERE)
Achieve exceptional control and precision in reverse. Yamaha’s TERE system cleverly diverts exhaust gases away from the propeller. This occurs at low RPMs (below 2,500). As a result, the propeller bites clean water. This significantly increases reverse thrust. It also greatly improves maneuverability for tasks like precise docking or backing down on fish.
TotalTilt™ for Effortless Operation
Simplify engine tilting with Yamaha’s exclusive TotalTilt™ feature. A quick double-tap of the trim/tilt button initiates a full tilt up or down. This makes trailering, mooring, and prop inspection quick and effortless. (Note: TotalTilt™ may be factory-defaulted to “OFF” for user preference, allowing activation as desired.)
Enhanced Durability and Serviceability
Built to withstand the harshest marine environments, the F350ESA features heavy-duty construction. It incorporates an upgraded gearcase with a redesigned clutch dog. This ensures stronger torque transfer. Plasma-fused sleeveless cylinder technology provides exceptional strength and reduces friction. An improved water sensor and increased oil cooler capacity further boost reliability.
Modern, Sleek Design
Inspired by the flagship XTO Offshore series, the F350ESA sports a fresh cowling design. It includes raised chrome graphics and a redesigned rear panel. A water-draining air duct and optimized cowling exhaust port keep components cool. This provides a clean, premium look while enhancing functionality.
