YAMAHA SPRING 67D-45560-00

Function and technical context

This spring is part of the suspension and damping system of Yamaha engines, working in coordination with the elements securing the engine to the boat. Its function is to absorb and distribute the vibrations generated during the operation of the propeller, protecting both the hull structure and the auxiliary systems mounted on the engine. A spring in poor condition causes excessive transmission of vibrations to the hull, acceleration of wear of adjacent components and loss of operational stability during navigation.

When to replace this part?

The springs show progressive wear after thousands of hours of operation, manifesting as increased vibrations in controls and structure, metallic noises during acceleration or change of speed, and excessive movement of the engine under load. It is recommended to inspect the condition of the dock at each seasonal inspection and replace it preventively if cracks, permanent deformations or loss of elasticity are observed, thus avoiding costly repairs derived from chronic vibrations at sea.
