R & D Flexible Shaft Coupling f/4" B/W, Hurth - 5HP/100RPM Capacity

The R & D Flexible Shaft Coupling for 4" B/W, Hurth is a critical drivetrain component designed for marine propulsion systems rated up to 5 HP and 100 RPM. This coupling is ideal for anglers and boaters who require reliable engine-to-shaft power transfer, ensuring smooth operation while on the water.

Constructed with elastomeric dampening material between the input and output hubs, this flexible shaft coupling effectively isolates vibration and misalignment, which can lead to premature wear on seals and bearings. The design allows for micro-movements that rigid couplings cannot accommodate, enhancing durability and performance.

This coupling is particularly beneficial for inboard engines in various marine applications, providing torsional shock absorption during acceleration and deceleration. While it is compatible with Hurth transmissions, proper installation and alignment are crucial for optimal performance.
