CP50 w/Louverd Windage Tray

The CHAMP PANS CP50 with Louvered Windage Tray is a rear-sump engine oil pan engineered for small-block Chevy applications in marine, street, and road race service. This 7-quart steel pan delivers the sump capacity and cooling surface area required for sustained high-performance operation in saltwater and freshwater environments where engine heat management and reliable lubrication circulation are critical to durability.

Measuring 7.75 inches deep with a two-piece seal design, the CP50 accommodates the geometry and mounting specifications of small-block Chevy powerplants while maintaining consistent oil level across varying sea states and acceleration profiles. Zinc-plated construction provides corrosion resistance in the salt-spray environment common to coastal and offshore operation. The louvered windage tray reduces turbulence and aeration within the pan, stabilizing oil temperature and pressure delivery to the engine under extended throttle cycles—a significant advantage over open-sump designs when operating in demanding conditions.

Buyers restoring or upgrading small-block Chevy marine engines—whether for commercial fishing vessels, recreational center consoles, or high-performance ski boats—choose rear-sump pans to match existing transom and mounting architecture. The CP50 serves both restoration work requiring OEM-pattern fitment and performance builds where enhanced cooling and windage control justify the specification upgrade.

At 12.55 pounds, the pan is substantial enough to handle the thermal load and vibration exposure of marine service without flex or leakage. The louvered design is a proven refinement in motorsports where oil control directly impacts engine longevity; the same principle applies to marine applications where saltwater corrosion and thermal cycling demand margin for reliability.
