Common Question of Yamaha LF115XB2 White
Is the white LF115XB2 counter rotating?
Yes. The white Yamaha LF115XB2 is specified with counter rotation and a 25-inch shaft. Its counter rotating lower unit is intended for compatible paired-engine applications. The white finish identifies appearance only, so verify propeller specification, controls, steering, battery, wiring, fuel system, and boat compatibility before installation.
What shaft length does it use?
The shaft length is 25 inches, intended for a matching tall transom. Measure the hull before purchase because incorrect shaft length can affect cooling-water pickup, gearcase depth, propeller immersion, steering response, and twin-engine balance. Proper measurement supports this ready to bolt marine outboard package.
Does it use fuel injection?
Confirm the exact Yamaha fuel system before making an EFI claim. The supplied title identifies a white counter-rotation model but does not explicitly state fuel injection. Verify controls, wiring, battery, steering equipment, gauges, propeller requirements, engine weight, and package contents through Yamaha documentation.
