Walter Split Shaft Coupling 4"C

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

The 4"C Walter Split Propeller Shaft Coupling is engineered for Paragon marine transmissions, delivering precise shaft alignment and simplified serviceability. Its split design allows the coupling to be installed or removed without pulling the shaft, making it an efficient solution for maintenance, repowers, and drivetrain upgrades.

Machined to tight tolerances, this coupling ensures a secure, concentric fit that helps reduce vibration and maintain smooth power transfer. Built for marine durability, it withstands high loads and harsh operating conditions typical of inboard propulsion systems.

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