Buck Algonquin Shaft Coupling 50-500YS

4-3/4" Buck Algonquin Split Propeller Shaft Coupling for Yanmar Marine Transmissions.

The Buck Algonquin 50-500YS Split Shaft Coupling is a heavy-duty 4-3/4" flange coupling engineered for use with Yanmar marine transmissions. Designed for inboard propulsion systems, this precision-machined coupling provides a secure and accurate connection between the transmission output flange and propeller shaft, ensuring efficient power transfer and reduced drivetrain stress.

Constructed from high-strength ductile iron, the 50-500YS is built to handle demanding marine environments while maintaining proper shaft alignment and efficient power transfer. The split coupling design allows for easier installation and removal without requiring shaft withdrawal, significantly reducing maintenance time and simplifying service procedures.
