Buck Algonquin Shaft Coupling 50-725BZF

7-1/4" Buck Algonquin Split Propeller Shaft Coupling for ZF Marine Transmissions.

The Buck Algonquin 50-725BZF Split Shaft Coupling is a heavy-duty 7-1/4" flange coupling specifically designed for ZF marine transmissions. Engineered for precise shaft alignment and secure connection, it ensures efficient power transfer between the transmission and propeller shaft.

The split design allows for easier installation and removal without full shaft disassembly, reducing service time and simplifying maintenance. Built from durable marine-grade materials, this coupling offers excellent strength, corrosion resistance, and long-term reliability in demanding marine environments.

Constructed from high-strength ductile iron and machined to strict marine tolerances, the 50-725BZF ensures reliable power transfer, proper shaft alignment, and long service life in demanding inboard applications.
