BBC Marine Oil Pan - Deep Rear Sump

The CANTON BBC Marine Oil Pan with Deep Rear Sump (Part No. 18-380) is a purpose-built marine engine oil pan engineered for big block Chevy marine applications. This 10-quart capacity pan features a rear sump design that optimizes oil flow and engine cooling in marine installations where proper crankcase ventilation and oil management directly impact reliability and longevity. The 10-inch deep construction provides adequate reservoir volume for sustained offshore and freshwater operation.

Constructed from steel with black powder-coat finish, this pan resists corrosion in the harsh salt-air and moisture-heavy marine environment. The two-piece seal design ensures a secure, leak-free fit when properly installed on your big block Chevy marine engine. At 23.5 pounds, the pan's weight reflects its heavy-gauge construction—critical for withstanding the vibration and thermal cycling typical of marine powerplants. The compact footprint (13.7 x 11.5 x 26.9 inches) allows integration into tight engine compartments found on recreational and commercial fishing vessels.

This oil pan is essential for weekend anglers rebuilding or maintaining classic big block Chevy marine engines, and for serious offshore fishing operations requiring OEM-grade or OEM-equivalent components. Whether you're running a freshwater bass boat or a salt-water charter vessel, the rear sump design maintains consistent oil delivery to the engine under various sea states and acceleration profiles. CANTON's reputation for precision marine engine parts makes this pan a factory-grade replacement or upgrade option for engine builders and marine technicians.
