Walter Split Shaft Coupling 4"AS

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

The 4"AS Walter Split “Short” Propeller Shaft Coupling is designed for Paragon marine transmissions where space constraints or limited shaft length require a more compact solution. This shortened version retains the full benefits of Walter’s split coupling design, allowing installation and removal without pulling the shaft—saving time during service and reducing labor costs.

Precision-machined for accurate fit and alignment, the coupling minimizes vibration and ensures efficient power transfer through the drivetrain. Its compact profile makes it ideal for tight engine compartments while still delivering the strength and durability required for marine applications.

Constructed from high-strength ductile iron and machined to strict marine tolerances, the Walter 4"AS ensures reliable power transfer, proper shaft alignment, and long service life in demanding inboard applications.
