Yamaha F350XSA 350HP – DEC 25″ Shaft Standard Rotationin Gray

Yamaha F350XSA 350HP Integrated Steering

The Yamaha F350XSA pairs a 4.3L 24-valve DOHC V6 with standard rotation, finished in Classic Gray at 529 lbs dry — a solid power-to-weight ratio for offshore vessels. The 25-inch shaft is built for platforms in Mulmarine’s outboard engine technology lineup that need the precision of integrated digital electric steering.

Technical Specifications of Yamaha F350XSA

• The V6 4.3L DOHC architecture delivers 350 horsepower with strong volumetric efficiency.
• The Gray 240 kg build runs a 25-inch shaft for offshore transom configurations.
• Multi-point EFI keeps combustion consistent across the 5000-6000 RPM throttle band.
• Integrated Digital Electric Steering (DES) delivers effortless handling and precise control at any speed.
• Digital Electronic Control (DEC) with Helm Master EX compatibility keeps shifting and helm management smooth.
• The 50-70 Amp alternator output keeps navigation displays and digital electronics powered.
• Coverage comes from a limited 3-year factory warranty and Japanese build standards.

V6 4.3L Integrated Command

The F350XSA uses a 24-valve V6 configuration to maximize air intake and torque, delivering hole-shot acceleration even when pushing a heavily loaded offshore hull through chop. Captains get smooth power and reduced vibration cruising through coastal chop with integrated digital command.

Integrated DES Steering

This 350HP outboard runs Integrated Digital Electric Steering (DES) for a smooth, responsive feel at the helm without external hydraulic lines. The digital electric steering system keeps the bilge clean while giving the operator adjustable steering friction. Anglers get to run long offshore tournament days without operator fatigue.

25-Inch Offshore Shaft

The 25-inch shaft is calibrated for modern offshore transom dimensions, keeping the prop from aerating in following seas while holding a secure grip on the water. US boaters get better steering authority and more stable tracking on aggressive maneuvers during transit.

Helm Master EX Integration

This 350HP outboard is fully compatible with Yamaha Helm Master EX for advanced positioning and joystick control at the helm, allowing precise movement in tight quarters and automated fishing patterns. Captains can manage multiple outboards through a single modern helm setup.

Routine Maintenance Protocol

This digital V6 runs high-quality sacrificial anodes to keep galvanic corrosion in check daily. Regular attention to the power trim and tilt system keeps engine adjustments smooth in saltwater environments. Pro Tip: flush the engine with fresh water after every launch to protect the cooling system and internal components from salt buildup.
