Cylinder Sleeve

The BRODIX Cylinder Sleeve (MPN 8BSL43075) is a critical engine block component designed for serious marine and high-performance boating applications. Whether you're rebuilding a vintage inboard, upgrading to a stroker package, or restoring a classic ski boat motor, this cylinder sleeve serves as the foundation for reliable, long-lasting bore integrity. Built to OEM specifications, it's the component you trust when boring out a block to reclaim lost compression and extend engine life on the water.

BRODIX cylinder sleeves are precision-engineered to maintain exact bore diameter and wall thickness, ensuring proper ring sealing and piston clearance under sustained engine loads—critical factors for marine engines that operate at consistent RPM for hours at a time. The 4.8 x 4.8 x 7.6 inch form factor accommodates standard block configurations, while the 1.9 lb weight reflects quality ductile iron or cast construction that resists corrosion and thermal stress in saltwater and freshwater environments alike. Proper installation requires careful honing and correct piston-to-wall clearance to maximize ring life and minimize blow-by.

Marine engine builders and dedicated boat owners rely on BRODIX sleeves when conventional boring isn't an option—damaged bores, worn cylinders, or oversized piston builds all benefit from a quality sleeve. Compatibility depends on your specific block and piston package; always confirm bore size, wall thickness, and installation depth with your machinist or engine builder before ordering. Proper installation with correct torque specifications and honing ensures maximum seal, minimal wear, and the performance consistency you need for weekend cruising or tournament fishing.
