Exhaust Elbow Gasket 18-2849-1 27-818832 Fit Mercruiser Stern Drive

• Exhaust Elbow Gasket: Precision OEM dimensions for a direct replacement. Compatible with part numbers 18-2849-1, 27-818832, and 27-863726; fits MerCruiser stern drive engines and Mercury Marine Sierra engines perfectly—no grinding or modification required, with easy alignment for installation.
• Compatibility: Suitable for Mercury Mercruiser V6/V8 engines; widely used on 1981–1997 Mercruiser stern drive models and Mercury Marine Sierra engines as a replacement gasket for exhaust elbows and risers.
• Premium Materials: Crafted from high-quality composite sealing material that withstands high temperatures and thermal cycling, enduring the harsh conditions of hot marine exhaust gases. Features excellent compression recovery to compensate for minor flange surface irregularities, effectively preventing exhaust and water leaks while protecting the exhaust manifold and engine.
• Exhaust Manifold Gasket: Resistant to seawater corrosion and oil degradation, making it suitable for both fresh and saltwater environments. Effectively prevents heat-induced aging and cracking, reduces engine compartment leaks, lowers the risk of engine rust, and extends the service life of the exhaust system.
• Package Contents: Includes a set of 4 exhaust elbow/riser gaskets to meet engine repair and assembly needs. Specifically designed for marine exhaust system maintenance, this is a reliable component for the routine servicing and major overhauls of yachts and speedboats; a cost-effective alternative to Sierra and Mercury OEM gaskets.
