Product Details

The Sierra 18-0476-1 is a blocked-style riser block-off gasket engineered for marine exhaust applications on Ford Small Block V8 engines (302-351 cubic inch displacement). This gasket is designed for use with Volvo Penta, Indmar, and Marine Power sterndrive engines.

Key Features:

  • Steel construction for durability in harsh marine environments
  • Blocked-style design maintains proper separation of exhaust and cooling channels
  • Precision-engineered to perfectly match exhaust and cooling ports
  • Compatible with Sierra risers 18-1939, 18-1999, and 18-1907

Cross-Reference Part Numbers:

  • Barr 01-0105
  • GLM 36820
  • Mallory 9-65500
  • Osco 992-G-FW

Exhaust manifolds and risers require regular inspection and maintenance to prevent catastrophic engine failure. When performing service or replacement work, it's critical to replace riser gaskets to ensure proper sealing and prevent mixing of exhaust gases and cooling water. Sierra gaskets meet or exceed OEM specifications and provide reliable performance for marine mechanics and boat owners.

Easy process. Delivered on projected date.
