Buck Algonquin Shaft Coupling 50-400C

4" Buck Algonquin Split Propeller Shaft Coupling for Paragon Marine Transmissions.

The Buck Algonquin 50-400C Split Propeller Shaft Coupling is a precision-machined marine coupling designed for reliable power transfer between Paragon marine transmissions and the propeller shaft. Built for strength and accuracy, it ensures proper shaft alignment and secure retention in inboard propulsion systems.

Constructed from high-strength ductile iron, the 50-400C 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.
