R&D 910-002 Flexible Coupling for 4" Yanmar

Flexible Coupling for Marine Applications

The R&D Flexible Coupling 910-002 is essential for any vessel equipped with 4" Yanmar gearboxes. It effectively bridges the gap between the propeller shaft coupling and the gearbox output, allowing for smooth operation even under temporary misalignments.

Constructed from a robust Polyester Elastomer, this coupling features a specially contoured flexible disc that absorbs shocks and compensates for movement induced by the boat's structure or engine positioning. This ensures continuous engagement while safeguarding against potential coupling disc failures, thanks to its fail-safe steel straps that maintain propulsion in all conditions.

Key Specifications:

• Maximum Diameter: 114.3mm (4.5”)
• Length: 32.5mm (1.28”)
• Bolt Diameter: M10
• Capacity: 2.24kW / 3HP per 100 RPM
• Designed for Yanmar Kanzaki Gearboxes
• Non-conductive electrical properties for safe operation
