R&D Flexible Shaft Coupling

Reduce engine noise and transmission vibration

Staggered bolts enable the polyester elastomer to isolate vibrations and compensate for some misalignment.


Reduce costly transmission repairs

Absorbs shock loads due to propeller impact or hard gear changes.


Fail safe design

Two steel straps prevent drive train from separating in the event of severe impact. The aft steel strap is bolted to the transmission coupling and the forword steel strap is bolted to the shaft coupling. The aft strap will engage the foreword strap and keep the drive train together if the elastomer is damaged.


Fits most major transmission makes and models

For engines 5 to 1500 HP.


Under compression load in both foreword and reverse

The aft steel strap bolted to transmission acts as a backing plate to prevent reverse thrust from pulling the element apart.


Quick and easy installation

The R&D Coupling requires no machining and comes supplied with bolts to connect between the two existing shaft flanges.


Periodically check alignment easily

Checking alignment on installation and during service checks is quick and easy using the red bolt as a reference and checking the gap while manually rotating the shaft.


Impervious to salt water, diesel and lubrication oils

The couplings are made from a polyester elastomer which is not affected by salt water, diesel and lubrication fluids.
