AXLE 6G5-45501-21

Function and technical context

The 6G5-45501-21 shaft is a critical component of the Yamaha engine transmission system, responsible for transmitting power from the engine to the propeller. This shaft supports continuous torsional stresses and must maintain precise alignment to ensure efficient operation of the vessel. Its deterioration or failure causes abnormal vibrations, loss of propulsion power and possible secondary damage to adjacent bearings and couplings.

When to replace this part?

Symptoms of wear include excessive vibrations during navigation, metallic noises in the transmission area and abnormal play in the shaft when performing manual tests. It is recommended to inspect the condition of the axle during each seasonal maintenance and before long sailings; Any curvature, crack or advanced corrosion requires immediate replacement to avoid breakdowns at sea that compromise the safety of the boat.
