Buck Algonquin Shaft Coupling 50-MC4526

4-1/2" Buck Algonquin Solid Propeller Shaft Coupling for Paragon Marine Transmissions.

The Buck Algonquin 50-MC4526 Solid Shaft Coupling is engineered for Paragon marine transmissions, providing a rigid and precise connection between the transmission output flange and propeller shaft. With a 4-1/2" flange diameter, this coupling is ideal for inboard applications where strength, alignment, and reliability are critical.

Its solid one-piece construction ensures maximum holding power and minimal flex, making it well-suited for permanent installations and demanding marine environments. Precision machining helps reduce vibration and maintain smooth drivetrain performance under load.

Constructed from high-strength ductile iron and machined to strict marine tolerances, the 50-MC4526 ensures reliable power transfer, proper shaft alignment, and long service life in demanding inboard applications.
