Common Question of Yamaha F300XSB2 White
Is the white F300XSB2 DEC?
Yes. The white Yamaha F300XSB2 is identified with DEC Digital Electronic Control and a 25-inch shaft. Confirm the exact fuel system, control components, harnesses, gauges, battery, steering equipment, and package contents before installing this high performance outboard motor.
What transom fits its shaft?
A 25-inch transom is the intended match for this white F300XSB2 model. Measure the hull according to Yamaha’s instructions before mounting because incorrect shaft length can affect cooling-water pickup, gearcase depth, 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.
