Engineered Marine Products 27-00942 Cylinder Base Gasket

The Engineered Marine Products (EMP) 27-00942 Cylinder Base Gasket is a precision-engineered replacement gasket designed to seal the junction between the cylinder block and the crankcase on outboard marine engines. This critical sealing component helps maintain proper compression, prevents oil and water intrusion into the powerhead, and ensures optimal engine performance.

EMP manufactures this gasket to meet or exceed OEM specifications, providing a reliable, drop-in replacement for worn or damaged original gaskets. Constructed from durable, marine-grade materials, the 27-00942 is built to withstand the demanding conditions of the marine environment — including exposure to fuel, oil, saltwater, and repeated thermal cycling.

Key Features:

• Precision die-cut to match OEM dimensions for a leak-free seal
• Marine-grade materials resistant to fuel, oil, and coolant
• Meets or exceeds original equipment manufacturer specifications
• Direct replacement — no modification required for installation
• Manufactured by Engineered Marine Products (EMP), a trusted name in marine engine sealing components

Replace this gasket any time the powerhead is removed for service, or when signs of compression loss, oil seepage, or coolant leaks are present at the base of the cylinder. Always verify fitment using your engine's model and serial number prior to installation.
