BEARING 93317-325U0

Function and technical context

This bearing is part of the set of support and rotation elements in Yamaha engines, allowing the free and controlled rotation of critical internal components of the propeller. Its function is to reduce friction between rotating surfaces, ensuring efficient power transmission and smooth engine operation. Wear or deterioration of this bearing compromises the alignment of internal components, generating vibrations, increased fuel consumption and progressive loss of power in marine propulsion.

When to replace this part?

Engine bearings show wear through metallic noises, abnormal vibration of the propeller and loss of general performance. It is recommended that the condition of this component be inspected during each seasonal maintenance check, especially after prolonged periods of intensive navigation. Preventive replacement prevents cascading damage that can disable the engine at sea and lead to significantly more costly repairs.
