Flexible Couplings

By fitting a flexible coupling between the gearbox and the propeller shaft, annoying vibrations in the boat are largely eliminated.
A flexible coupling ensures the diminishing of vibrations and noise to a great extent. The average noise reduction amounts to about 5 dBa, or up to 30%.

Misalignment of the propeller shaft can also be compensated, with the result that gearbox and shaft bearing are less subjected to wear and tear.
