FLEXIBLE OUTPUT COUPLINGS
A flexible coupling mounted on the gearbox output flange is strongly recommended. Flexible couplings do not resolve
poor alignment as they are designed to absorb torsional vibrations from the propeller which are transmitted along the
propeller shaft. Beta Marine can offer:
R&D Coupling`s with a flexible nylon disc and optional Clamp Coupling.

R&D Flexible Couplings
The CentaFlex coupling design is able to absorb high torsional shocks and loads. These couplings are
complete and replace the need for both a R&D flexible coupling and clamp coupling above.

NB: If a constant velocity drive shaft is being considered
for fitting then it maybe necessary to have the standard
engine drive plate that is supplied replaced to avoid
torsional noise problems. Please contact Beta Marine for
technical guidance.
