YAMAHA THICK 626-45577-00 PAF15-06080006-1

Function and technical context

The shim disc is a critical component of the transmission system in small displacement outboard engines, responsible for the transfer of power from the crankshaft to the propeller. This part works inside the gearbox, subject to constant friction and wear during acceleration, reverse and speed changes. Its deterioration causes slippage of the transmission, loss of grip in the water and difficulty in reaching engine revolutions, compromising maneuverability and navigation safety.

When to replace this part?

Typical symptoms include transmission slippage (engine revving but boat with no propulsive response), abnormal vibration in the shift lever, or inability to engage reverse gear firmly. Although there is no fixed maintenance interval for this component, it is recommended to inspect the condition of the disc during each seasonal service and replace it if cracks, deformation or insufficient friction are observed. A preventive replacement before the summer season avoids unexpected breakdowns in the middle of the water and guarantees the reliability of the boat.
