Common Question of Yamaha F350XSA2 White
Is the white F350XSA2 DEC?
Yes. The white Yamaha F350XSA2 is identified with DEC Digital Electronic Control and a 25-inch shaft. The white finish identifies exterior color, while the exact fuel system and control components require confirmation. Verify harnesses, gauges, battery, steering, transom strength, and package contents before installing this high performance outboard motor.
What shaft length does it use?
The shaft length is 25 inches, intended for a matching tall transom. Measure the boat before purchase because incorrect shaft length can affect cooling-water pickup, gearcase clearance, propeller immersion, steering response, and trim. Correct measurement supports this ready to bolt marine installation.
Does the white finish change performance?
No. The white finish changes exterior appearance rather than the listed horsepower or shaft length. Confirm DEC controls, wiring, gauges, battery requirements, steering equipment, fuel system, engine weight, and package contents through Yamaha documentation before installation.
