VERTICAL SHAFT 6E7-45501-00 REC6E7-45501-00

Function and technical context

The 6E7-45501-00 vertical shaft is a fundamental structural component in the power transmission of the marine engine, responsible for transferring the rotation of the crankshaft to the propeller through the propulsion system. This axis works within the vertical transmission system, supporting extreme torsion efforts and constant vibrations during navigation. Its correct operation is critical to guarantee efficient propulsion and avoid loss of power or erratic movements of the boat that compromise maneuverability and safety in the water.

When to replace this part?

Replacing the vertical shaft becomes necessary when excessive vibrations are observed during acceleration, metallic noises in the transmission area or gradual loss of engine response to changes in revolutions. Although there is no set maintenance interval, it is advisable to visually inspect the condition of the shaft during each seasonal inspection and check its alignment, especially if the boat has been impacted or grounded. Carrying out the replacement preventively avoids sudden breakdowns at sea and significantly prolongs the useful life of the rest of the transmission components.
