PIN 90250-06023 REC90250-06023

Function and technical context

This pin plays a critical holding and alignment role in the transmission and drive mechanisms of Yamaha and Mercury marine engines. It is a fixing element that ensures the correct position of rotating or articulated components, avoiding misalignments that would compromise the mechanical efficiency of the propeller. Its correct condition is essential to guarantee that power transmission is precise and that no abnormal vibrations or parasitic movements occur that could lead to secondary damage to adjacent systems.

When to replace this part?

The pins may show wear due to marine corrosion, mechanical fatigue from repeated operating cycles, or deformation due to impacts on the propeller. It is recommended to inspect its condition during each seasonal inspection, especially on saltwater boats where rust progresses more quickly. Preventative replacement of damaged or deformed pins prevents costly offshore gearbox or driveshaft repairs.
