Flexible Shaft Coupling for 5" B/W, Hurth - 8HP/100RPM CapacityThe 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 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 = 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

Extra large paper bowls are sturdy, affordable, and make clean up a breeze.
Style: 34 Ounces, Size: 34 Count
I like the convenience of paper plates and these large 34 oz. bowls are perfect for microwave cooking. They are deep enough to handle soup, pasta, stuffing and vegetable sides with no problems and without any leaking, and are a good value for the price. They look stylish and make clean up less of a chore. You can't go wrong with Dixie paper products. They're sturdy, fun, and last through the meal.

Strong, Spacious, and Perfect for Every Meal
Style: 34 Ounces, Size: 34 Count
I’ve been using the Dixie Ultra Extra Large Paper Bowls for a while now, and they really stand out. With a 34 oz capacity, these bowls are big enough to hold hearty meals like soups, stews, and even large salads without worrying about spills. They’re perfect for heavy meals or when you just want a generous portion.
What I appreciate most is that they’re compostable, which makes me feel better about using disposable products without harming the environment. Plus, they’re microwave safe, so reheating leftovers is super easy and convenient. The bowls are sturdy and don’t get soggy or flimsy, even with hot or liquid foods, which is a huge plus.
Whether you’re having a casual lunch, a family gathering, or need something reliable for everyday use, these bowls deliver both quality and convenience. They handle big meals with ease and clean-up is a breeze. Definitely a smart choice for anyone who wants disposable bowls that actually hold up!
