Product Details

The Sierra 18-0333 is a marine powerhead-to-mounting plate gasket engineered as a direct aftermarket replacement for Mercury and Mariner outboard motors. This individual gasket seals the mating surface between the powerhead and the lower mounting plate, preventing exhaust and water leaks that can compromise engine performance and longevity.

Key Features:

  • Replaces OEM Mercury/Mariner part number 27-39401
  • Precision-cut to match OEM bolt hole and port patterns for a leak-free fit
  • Manufactured to meet or exceed original equipment specifications
  • Designed to withstand the demanding thermal and mechanical conditions of marine powerhead applications
  • Sold as a single gasket

Sierra International has been a trusted supplier of aftermarket marine parts for over 50 years, offering boaters reliable, high-quality replacement components. The 18-0333 is an ideal choice for engine rebuilds, powerhead R&R service, or anytime the powerhead-to-plate seal needs replacement.
