R & D Flexible Shaft Coupling f/5" Yanmar - 10HP/100RPM Capacity

The R & D Flexible Shaft Coupling for 5" Yanmar is a critical drivetrain component designed to connect your engine to the propeller shaft with precision and reliability. This coupling is specifically engineered for small to mid-range marine applications, particularly for Yanmar engines with a 10 HP / 100 RPM capacity, commonly found in commercial fishing boats and pleasure vessels.

The flexible design of this coupling absorbs minor misalignment and vibration between the engine and propeller shaft, protecting both components from shock loads and extending their service life. It accommodates slight angular and radial misalignment that occurs naturally in boat installations, ensuring smooth operation and reducing stress on transmission seals, bearings, and shaft journals.

This coupling is particularly beneficial for marine mechanics and hands-on boat owners looking to replace a worn coupling on a Yanmar engine. Its lightweight design at 3.6 lbs and compact dimensions make installation straightforward, providing peace of mind for those who rely on their vessels for work or recreation.
