Made from flexible marine-grade rubber and supplied with two SS316 stainless‑steel clamps, the GHmarine bellow restores a secure, corrosion-resistant connection between exhaust elbow and riser or tailpipe. Check your engine’s bellows shape — some early 5.7L GM-based units have a raised \"lump\" in the bellow profile while later models do not — to ensure you order the correct variant.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this bellow fit my Voolvo Penta or OMC Cobra engine?\u003c\/h3\u003e\n\u003cp\u003eThe GHmarine 3863450 is manufactured to match original mounting dimensions for many 4‑, 6‑ and 8‑cylinder marine engines. It replaces multiple OEM part numbers and fits common displacements used in marine applications. Before installing, compare the flange spacing and overall profile with your old bellow.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eCompatible replacements: Voolvo 3863450, OMC 3852741, GLM 89222, Mallory 9-72800, Sierra 18-2780-1\u003c\/li\u003e\n  \u003cli\u003eFits engines: 2.3L, 2.5L, 3.0L, 4.3L, 5.0L, 5.7L, 5.8L, 7.4L, 8.1L (1994 and newer)\u003c\/li\u003e\n  \u003cli\u003eIncludes: 2 x SS316 stainless-steel clamps sized for secure clamp-down\u003c\/li\u003e\n  \u003cli\u003eProfile note: check for early 5.7L \"lump\" configuration before ordering\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat materials and durability features should I expect?\u003c\/h3\u003e\n\u003cp\u003eThis bellow is molded from marine-grade rubber formulated to resist heat cycling, exhaust condensates and saltwater exposure.
