9in Floater Bare Housing 60in Centered 2.5in GN

The 9in Floater Bare Housing 60in Centered 2.5in GN by PEM is a specialized marine shaft coupling component designed for serious boaters and commercial marine operators who demand reliability in demanding saltwater and freshwater environments. This floater housing assembly serves as a critical interface in drivetrain systems, absorbing misalignment and vibration while maintaining precise rotational transfer between engine and propulsion shafts. Built for vessels ranging from mid-size recreational boats to commercial fishing operations, this component protects downstream equipment from shock loads and extends the service life of your entire propulsion system.

This bare housing design features a 60-inch centered mounting configuration with a 2.5-inch gauge section, optimized for vessels with extended shaft runs or complex engine-to-prop alignments common in larger hulls. The 9-inch floater diameter provides excellent angular and parallel misalignment compensation while the centered bore geometry allows predictable load distribution across the coupling assembly. At 54.24 pounds, the housing weight is substantial enough to ensure structural integrity under continuous duty cycles while the rigid aluminum or ductile iron construction resists corrosion and fatigue—essential characteristics for boats operating in challenging marine conditions. The bare housing configuration allows you to specify elastomer inserts and fastening hardware matched to your exact operational requirements, giving experienced technicians full control over dampening characteristics and performance tuning.

This coupling housing benefits commercial fishing fleets, charter boat operators, and serious recreational boaters with high-horsepower installations who need aftermarket upgrade options or replacement components for aging systems. Installation requires proper shaft alignment and familiarity with coupling assembly procedures—consult your engine and transmission manufacturer's documentation to confirm compatibility with your specific shaft sizes, keyway dimensions, and mounting bolt patterns. The 14.5 x 9.5 x 60.5 inch envelope fits standard shaft tunnel configurations, though pre-installation measurement of your existing coupling or shaft run is strongly recommended to ensure correct sizing.
