# - For the Hurth HBW 150 V Gearbox an adapter 202-351 is required (0.875" long).
For the IRM 220A Gearbox, we can supply adapter plate 202-384 (2.125" long) and for the Twin Disc 502 Gearbox, adapter plate 202-148 (2.125" long) that bolts onto flexible couplings 910-003, 910-025 or 910-032 and with half coupling 202-037 or 202-054, alternatively clamp type 202-176 or 202-178.
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 taken again 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. 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 that is 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 add 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 inspection of alignment 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.
We keep all the common R&D Marine Flexible Couplings in stock; however, for a few of the less common sizes will have to be special ordered. Special Order Items will take approximately 2 to 3 weeks to ship out.
The coupling rating needed is 12hp. By looking at the chart below, we can determine the coupling required is a 910-009 Borg Warner.

HI ERIC, Yvette was my ex.
I am Pierre and yes it's perfect. Very good service.
Thanks again!
I was extremely pleased with this purchase and support. I believe it was Miles that helped me well done!
Ordered a part and gave them the wrong shipping address. UPSP returned the part to PYI. They resent the item for me (once I gave the them the correct address!). Very accommodating and responsive. Highly recommend PYI for top-notch customer service (not something you can say about everyone these days).
All good! Thanks.
