YAMAHA AXLE 20 6E5-45501-01

Function and technical context

The Yamaha 6E5-45501-01 20-inch shaft is the power transmitting component of the Yamaha outboard motor propulsion system, responsible for transferring the rotation of the crankshaft to the propeller through the gearbox. This axis works integrated into the stern column and supports continuous torsional forces, hydraulic vibrations and the dynamic load generated during navigation. Its correct operation is critical to guarantee efficient, stable and safe propulsion; Wear or damage to this axle can cause loss of traction, abnormal noises in the transmission, and even the total inability of the boat to move.

When to replace this part?

Symptoms of wear on drive shafts include excessive play in the propeller, metallic noises during acceleration, abnormal vibrations in the stern column, and difficulty engaging reverse gear. It is recommended to check the condition of the shaft during each seasonal maintenance and, especially, after navigation in waters with sediment or after impacts against submerged objects. Preventive replacement of the shaft avoids unexpected breakdowns during navigation and the risk of being left without propulsion in adverse conditions.
