The R&D Marine Clamp Coupling is machined from solid steel and mates with the gearbox output coupling to connect the propeller shaft to the gearbox, usually via an R&D Flexible Coupling.

The clamp on split type propeller shaft coupling is machined to suit the propeller shaft diameter. It is simple to install and can be adjusted to the required position on the shaft. This clamp on shaft coupling is bored and is secured to the boat propeller shaft with the clamp bolts supplied.

Accurate shaft diameter and gearbox output flange measurements required  when ordering.

Recommended torque for the clamp bolts: 54Nm (40 lbsft).
