Genuine factory original equipment Duramax Marine Johnson Cutless metallic sleeve metric bearing assembly. This premium heavy-duty propeller shaft component safeguards your vessel's mechanical drivetrain layout by providing a high-efficiency, water-lubricated sleeve alignment structure that keeps vital running gear operating smoothly. Featuring precision-machined naval brass outer shells and an oil-resistant nitrile rubber internal lining, it installs cleanly right inside your boat's strut or stern tube mount to ensure maximum vibration absorption and prevent catastrophic shaft whip or premature hardware wear under grueling open-water throttle loads. (Note: In strict alignment with OEM industrial warehouse distribution standards for bulk stock batches, this genuine unit features a standard smooth outer shell finish and does not feature any physical manufacturer name or part number engravings stamped anywhere on the exterior brass shell).

• Key Features: Advanced water-lubricated hydrodynamic pocket structure, heavy-duty marine-grade naval brass outer shell with smooth machined finish, chemical and oil-resistant nitrile rubber inner polymer lining, and a grit-rejecting grooved design.
• Technical Specs: Brand: Duramax Marine / Johnson Cutless | Shaft Diameter (ID): 65 mm | Outside Diameter (OD): 85 mm | Overall Length: 260 mm | Shell Material: Smooth Machined Naval Brass.
• Condition Notes: This item is in new, unused original warehouse condition with no manufacturer name or part number engraved on the bearing shell. The exterior brass wall features a factory-smooth finish and exhibits minimal superficial storage smudges or light handling marks from bulk bin inventory placement, but the component is physically flawless with zero pitting, scoring, structural deformations, or internal rubber lining compromises.
• Installation Notes: Slide the sleeve bearing directly into your vessel's dedicated strut or stern tube housing using a light press-fitting technique. Secure the outer shell firmly in place utilizing standard cone-pointed set screws to prevent rotational walking during shaft movement. If shrink-fitting is required for tight clearances, achieve gradual cooling to no lower than -20°F (-28°C) using standard refrigeration or regular ice—do not use dry ice or subject the chilled shell to heavy pounding forces to eliminate the risk of internal rubber separation.
