Spacer Mis-Alignment 5/8 -1/2in 1.00in OAL Each

The Spacer Mis-Alignment 5/8 - 1/2in 1.00in OAL Each from WEHRS MACHINE is a precision marine hardware spacer engineered to correct alignment issues in drivetrain and shaft coupling applications. If you've spent years on the water, you know that even minor misalignment between engine shafts and propeller drives compounds vibration, bearing wear, and fuel inefficiency over time. This spacer addresses that problem directly, allowing boaters and marine technicians to fine-tune coupling geometry without complete disassembly of critical systems.

Built to WEHRS MACHINE's exacting standards, this spacer features a stepped design that bridges the 5/8-inch and 1/2-inch bore diameters commonly found in marine gearbox and shaft installations. The 1.00-inch overall length (OAL) provides the offset necessary to correct moderate misalignment while maintaining load-bearing integrity under the shock and vibration loads typical of propulsion systems. The compact 0.09-pound weight ensures minimal impact on balance, and the precision-machined aluminum or steel construction resists corrosion in saltwater and freshwater environments alike. This is the kind of component that prevents catastrophic coupling failure mid-trip.

Marine mechanics and DIY boaters rely on mis-alignment spacers when retrofitting engines, upgrading to higher-horsepower units, or restoring vintage vessels where shaft wear has accumulated. Installation requires basic hand tools and familiarity with coupling geometry; consult your engine manufacturer's manual or a qualified marine technician to verify bore sizes and spacing before ordering. This single spacer suits inboard and outboard drive systems where shaft concentricity must be restored without replacing the entire coupling assembly. Stock one aboard for emergency repairs or keep several in your shop for seasonal maintenance projects.
