Common Question of Yamaha LXF450ESA
Is LXF450ESA counter rotating?
Yes. The Yamaha LXF450ESA XTO Offshore is specified as a counter-rotation 450-horsepower outboard with a 35-inch shaft. Its counter rotating lower unit is intended for compatible paired-engine applications. Confirm propeller specification, engine pairing, XTO controls, steering, battery, wiring, and boat compatibility before installation.
What transom fits its shaft?
A 35-inch transom is the intended match for this LXF450ESA configuration. Measure the hull according to Yamaha’s instructions before mounting because incorrect shaft length can affect cooling-water pickup, gearcase clearance, propeller immersion, steering response, and paired-engine balance. Correct measurement supports this ready to bolt marine installation.
Does it use fuel injection?
Confirm the exact Yamaha fuel system before making an EFI claim. The supplied title identifies XTO Offshore and counter rotation but does not explicitly state fuel injection. Verify controls, wiring, battery, steering equipment, fuel supply, gauges, propeller, engine weight, and package contents before installing this high performance outboard motor.
