SILENT LOCK 670-44514-00 REC670-44514-00

Function and technical context

The silemblock 670-44514-00 is an elastomeric damping and vibration isolation element that is part of the suspension and fixing structure of the outboard motor. This component absorbs and dissipates the vibrations generated during the operation of the propeller, protecting it from excessive movements and guaranteeing a stable fixation on the aft console. Its correct operation is essential to maintain the alignment of the drive shaft, reduce the transfer of vibrations to the hull and prolong the useful life of the engine and its annexed systems.

When to replace this part?

Silemblocks degrade due to aging of the elastomeric material, exposure to UV rays, marine salinity and chronic vibrations. The most obvious symptoms of wear include excessive engine movement, abnormal vibrations transmitted to the rudder or structure, metallic noise in the mounting and visible misalignment of the propeller. It is recommended to inspect these elements during each seasonal maintenance and replace them preventively every 3 to 5 years or when loss of elasticity is observed. A preventive change in time avoids breakages of more expensive components and emergency repairs while sailing.
