Walter Split Shaft Coupling 4"A

4" Walter Split Propeller Shaft Coupling for Paragon Marine Transmissions.

The 4"A Walter Split Propeller Shaft Coupling is designed for accurate shaft alignment and dependable performance with Paragon marine transmissions. The split design allows for straightforward installation and removal without the need to pull the shaft, significantly reducing service time and labor.

Precision-machined for a secure and concentric fit, this coupling helps minimize vibration, improve drivetrain efficiency, and protect transmission components under load. Built for durability in harsh marine environments, it is well-suited for both recreational and commercial inboard applications.

Constructed from high-strength ductile iron, the 4"A 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.
