R&D Flexible Shaft Couplings

Engine Mounts

The R&D Marine Engine Mounts are designed specifically for the rigors of marine applications. The mounts are stiff enough to absorb forward and reverse propeller thrust, yet soft enough to isolate drivetrain vibrations from the hull.

SPLIT COUPLINGS

R&D Marine has developed a comprehensive range of competitively priced Steel Clamp Half Couplings with flange sizes from 4" to 7-1/4" diameter.

FLEXIBLE SHAFT COUPLINGS

The R&D Marine Flexible Coupling fits between the transmission output flange and shaft coupling. It is designed to protect a boat's drivetrain. The unit will reduce vibration, compensate for some misalignment, isolate the shaft and absorb shock loads.

Damper Drive Plates

R&D Marine Damper Drive Plates are designed to prevent gearbox rattle at low engine speeds, which allows an engine to operate through its entire RPM range.
