#Model-F350XSA Yamaha F350XSA Outboard Motor 25-Inch Shaft | 4.3-Liter V6 | Digital Electronic Control | EFI | Electric Start | Power Trim & Tilt | Gray The Yamaha F350XSA is Yamaha’s strongest V6, built for offshore boats that need serious power without moving up to a V8. This 4.3-liter platform pushes hard through the midrange and feels lighter and more balanced than the older big-block designs. It’s the kind of engine that works well on heavy center consoles and offshore fishing boats that spend most of their time in rough water. DEC controls help smooth out throttle response and shifting, so driving the boat feels cleaner and more controlled. ⚠️ Important: DEC engines must be installed and programmed by an authorized Yamaha dealer using Yamaha diagnostic tools. Key Features Engine Type: 4.3L V6 Horsepower: 350 HP Controls: Digital Electronic Control (DEC) Fuel System: Electronic Fuel Injection (EFI) Start Type: Electric Start Trim & Tilt: Power Trim & Tilt Shaft Length: 25" Max RPM Range: 5000–6000 RPM Displacement: 4.3L (4332cc) Alternator Output: 70 amps Corrosion Protection: Yamaha alloys + coatings Noise/Vibration Control: Tuned exhaust & intake Weight: Approx. 804 lbs Why Choose the F350XSA? Strongest V6 Yamaha has ever produced Standard rotation for multi-engine setups Smooth DEC shifting and throttle input Lighter and more balanced than older V8s Designed for offshore hulls with standard transoms Frequently Asked Questions Q: What boats suit the F350XSA? Heavy center consoles, offshore fishing boats

and large recreational hulls. Q

Does the F350XSA need professional installation? Yes — DEC motors must be programmed at the dealership. Q: How is it different from older F350 V8s? This V6 is lighter, more efficient, and better balanced while delivering similar offshore power. #Model-F350USA Yamaha F350USA Outboard Motor 30-Inch Shaft | 4.3-Liter V6 | Digital Electronic Control | Electronic Fuel Injection | Electric Start | Power Trim & Tilt | Gray The Yamaha F350USA is the 30-inch shaft version of Yamaha’s most powerful V6, built for bigger offshore boats that sit higher on the transom. It uses the same 4.3-liter platform as the rest of the F350 series, and the motor has a strong, confident feel all the way from the hole shot through the midrange. Because it’s lighter and better balanced than the older V8 models, the boat responds quicker and feels more stable when you’re running in rougher water. The DEC system makes the throttle and shifting extremely smooth — no cable lag or hesitation — which helps a lot when docking a heavy center console or maneuvering offshore. The extra shaft length keeps the prop deeper in the water on tall transoms, so it maintains bite even when the boat pitches or rolls. ⚠️ Important: This DEC model requires dealer installation and programming. Yamaha diagnostic tools are needed to set it up properly. Key Features Engine Type: 4.3L V6 Horsepower: 350 HP Shaft Length: 30" Fuel System: Electronic Fuel Injection (EFI) Controls: Digital Electronic Control (DEC) Start Type: Electric Start Trim & Tilt: Power Trim & Tilt Max RPM Range: 5000–6000 RPM Displacement: 4.3L (4332cc) Alternator Output: 70 amps Corrosion Protection: Yamaha alloys & protective coatings Noise/Vibration Control: Tuned intake/exhaust Approx. Weight: 804 lbs Why Choose the F350USA? Designed for offshore boats with higher transoms Very strong acceleration and torque for large center consoles Smooth DEC throttle and shifting for refined control Lighter and more efficient than older Yamaha V8 designs Reliable power for long offshore runs Frequently Asked Questions Q: How is the F350USA different from the F350XSA? Same motor, but the USA uses a 30-inch shaft; the XSA version uses a 25-inch shaft. Q: Does this engine need a dealer to install it? Yes — all DEC motors require professional programming. Q: What boats pair best with the F350USA? Deep-V center consoles, large offshore fishing boats, and any hull with a high transom needing a 30-inch mount. #Model-F350ESA Yamaha F350ESA Outboard Motor 35-Inch Shaft | 4.3-Liter V6 | Digital Electronic Control | Electronic Fuel Injection | Electric Start | Power Trim & Tilt | Gray The Yamaha F350ESA is the extra-long-shaft version of Yamaha’s strongest V6 offshore motor. It’s built for large boats that sit high off the water and need the prop deeper than a standard or long-shaft engine can reach. The 4.3-liter V6 delivers a ton of torque and feels steady even on heavier offshore hulls. It accelerates hard, holds power through the midrange, and still manages to stay lighter and more balanced than the older Yamaha V8s it effectively replaces. Because it uses DEC controls, throttle and shifting feel smooth, clean, and very predictable. That’s especially helpful on big center consoles or offshore fishing boats where precise maneuvering matters. The Gray finish keeps the traditional Yamaha look while offering strong corrosion resistance for saltwater use. ⚠️ Important: This DEC engine must be installed and programmed by an authorized Yamaha dealer using Yamaha diagnostic equipment. Key Features Engine Type: 4.3L V6 Horsepower: 350 HP Shaft Length: 35" Fuel System: Electronic Fuel Injection (EFI) Controls: Digital Electronic Control (DEC) Start Type: Electric Start Trim & Tilt: Power Trim & Tilt Max RPM Range: 5000–6000 RPM Displacement: 4.3L (4332cc) Alternator Output: 70 amps Corrosion Protection: Yamaha alloys & multilayer coatings Noise/Vibration Reduction: Tuned intake/exhaust Approx. Weight: 804 lbs Why Choose the F350ESA? Extra-long 35" shaft sits the prop deep for big offshore hulls Smooth DEC control makes handling easier in tight situations Strong power and torque for heavy center consoles and offshore rigs More balanced and efficient than Yamaha’s older V8 designs Built for long-distance offshore reliability Frequently Asked Questions Q: How is the F350ESA different from the F350USA? Same motor and finish — the ESA has a 35-inch shaft
