Common Question of Yamaha LF300ESB
Is LF300ESB counter rotating?
Yes. The Yamaha LF300ESB is specified as a DEC counter-rotation 300-horsepower outboard with a 35-inch shaft. Its counter rotating lower unit supports compatible paired-engine applications. Confirm propeller specification, engine pairing, DEC controls, steering, battery, wiring, and boat compatibility before installation.
What shaft length does it use?
The shaft length is 35 inches, intended for a matching extra-tall transom. Measure the boat before purchase because incorrect shaft length can affect cooling-water pickup, gearcase clearance, propeller immersion, steering response, and twin-engine balance. Proper measurement supports this ready to bolt marine installation.
What should buyers verify?
Verify the exact fuel system, propeller, controls, harnesses, gauges, battery connections, steering hardware, engine weight, transom strength, and package contents. The supplied title does not specify EFI, so confirm technical details through Yamaha documentation before repowering or operating this high performance outboard motor.
