Flexible Shaft Coupling for 5" B/W, Hurth, & Volvo - 25HP/100RPM Capacity
The R & D Marine Flexible Coupling consists of a flexible disc molded with a polyester elastomer. The disc gives clearance for bolt heads and is able to flex freely to take up any temporary misalignment of the engine and shaft due to flexing of the boat structure or the engine moving on its mount. Forward thrust is taken in compression on the disc between the two half couplings, and reverse thrust is retaken in compression on the disc between the two fail-safe straps. In the unlikely event of a severe impact, the steel straps make the coupling fail-safe and ensure the drive is maintained both forward and reverse.
Reduce Engine Noise & Transmission Vibration
Staggered bolts enable the element to isolate vibrations and compensate for some misalignment.
Reduces Costly Transmission Repairs
Absorbs shock loads due to hard gear changes.
Fits Most Major Transmissions
For engines, 5 to 1,500 horsepower It fits brands such as Borg Warner, ZF-Hurth, Twin Disc, Volvo, Yanmar, Technodrive, and more.
Under Compression Load In Both Forward & Reverse
The aft steel strap bolted to the transmission acts as a backing plate to prevent reverse thrust from pulling the element apart.
Quick & Easy Installation
The R & D Marine Flexible Coupling requires no machining and comes supplied with bolts to connect between the two existing shaft flanges.
Extremely Durable
Impervious to saltwater, diesel, and lubrication oils. The Flexible Couplings are made from a polyester elastomer not affected by saltwater, diesel, or lubrication fluids.
Fail-Safe Design
A fail-safe design is incorporated in the R & D Flexible Shaft Coupling that prevents the two couplings from pulling apart in the event of an impact or element failure, whereas other couplings do not. This fail-safe design is accomplished by using two steel straps and thru-bolts going into both the shaft coupling and transmission output flange. The aft steel strap is bolted to the transmission output flange, and the front strap is bolted to the shaft coupling. In the event of an impact, the aft steel strap (bolted to the transmission) will catch the front steel strap (bolted to the shaft coupling) and prevent the drivetrain from pulling apart.
The R & D element will absorb the shock load (reducing or eliminating damage to the transmission) and will maintain contact between the two couplings. The steel straps also keep the R & D Flex-Coupling under a compression load in both forward and reverse operation (the aft strap bolted to the transmission acts as a backing plate).
Machined Not Molded
The Drivesaver is molded, while the R & D Flexible Shaft Coupling is machined. Both designs suggested that you first set your alignment by drawing the two couplings up to each other and then adding the flex-coupling. The machined part will have MUCH tighter tolerance than a molded part.
Checking Alignment
The R & D Flexible Shaft Coupling allows for alignment inspection after the element is bolted in place. There is one bolt head that is machined and painted red. After the R & D Flexible Shaft Coupling is bolted into place, a feeler gauge can be slipped between the red bolt head and the coupling. This process is repeated with the same bolt four times at 90-degree intervals by rotating the shaft. If the gap is within .010" (0.25mm), the engine is accurately aligned.
To calculate the power of the coupling required:
Horse Power of Engine x Reduction Ratio x 100 = HP/100RPM
Engine Speed
Example:
Ford 150 HP at 2500 RPM with Borg Warner Velvet Drive 72C 2:1 Reduction Ratio
Engine Horse Power is 150 HP, Max Rated RPM is 2500, Reduction Ratio is 2:1
150/2500 x 2 x 100 = 12 HP per 100RPM

Flexible Shaft Coupling for 4" Yanmar - 3HP/100RPM Capacity
The R&D Flexible Couplings are fabricated from a contoured flexible disc molded in tough yet resilient new type polyurethane. The contoured disc gives clearance for the bolt heads, and is able to flex freely to take up any temporary misalignment of the engine and shaft, due to flexing of the boat structure or the engine moving on its rubber vibration isolation mountings. Forward thrust is taken in compression on the disc between the two half couplings and reverse thrust is taken again in compression on the disc between the two fail straps. In the unlikely event of a disc failure the steel straps make the coupling fail safe and ensure drive is maintained in both forward and reverse.
To calculate power of coupling required:
Horse Power of Engine x Reduction Ratio x 100 = HP/100RPM
Engine Speed
Example:
Ford 150HP at 2500RPM with Borg Warner Velvet Drive 72C 2:1 Reduction Ratio
Engine Horse Power is 150HP, Max Rated RPM is 2500, Reduction Ratio is 2:1
150/2500 X 2 x 100 = 12HP per 100RPM
Coupling required is 910-009
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.
The flexible disc is machined from a resilient and durable polyurethane. It allows the unit to flex, absorbing vibrations and temporary misalignment of the shaft and engine due to movement of the engine or flexing in the vessel's structure.
The polyurethane disc is backed up by two metal compression straps, one on either side of the flexible coupling. These metal straps hold the system in constant compression whether the drivetrain is in forward or reverse. This feature extends the life of the system dramatically.
The R & D Marine Flexible Coupling will also absorb shockloads resulting from gear changes, or the propeller striking a submerged object. The polyurethane disk will distort with light shock loads and is designed to be sacrificial in the event of severe shock load, saving on expensive drivetrain repairs. If the disc is destroyed from massive shockload the metal compression straps keep the coupling intact ensuring that the drive system is functional in both forward and reverse.
Why R&D Marine Flexible Shaft Couplings?
Polyurethane flange creates a flexible barrier to reduce drivetrain noise and vibration to quiet your drivetrain
Absorbs transmission shock load caused by the propeller and high speed gear changes. This helps to reduce and avoid costly transmission damage
Fail safe design, both forward and reverse thrust is taken in compression from the steel straps, giving a durable design even in extreme conditions
