Exhaust Rubber SIERRA 18-2748

Compatible Engines

Properly matching exhaust system components is the foundation of safety and longevity for your vessel. The SIERRA 18-2748 exhaust rubber is a high-quality damping element designed specifically for MERCRUISER engines. With precise manufacturing, this seal effectively isolates vibrations and compensates for relative movement between the engine block and rigid exhaust components, preventing pipe cracks and exhaust leaks.

The product is fully compatible with popular power units, including MCM 120, 140 models, as well as GM V-6 and V-8 engines. We particularly recommend it for boats equipped with MERCRUISER D2.8L/165 D-TRONIC configurations and VM 169 I/L4 engines. Using the original SIERRA exhaust rubber (catalog number 18-2748) guarantees a perfect fit to mounting holes, ensuring easier installation and long-term system integrity. Do not risk damaging an expensive engine with cheap alternatives—choose the proven solution with EAN: 030999752963.

Installation and Maintenance

• Vibration Protection: The elastic rubber absorbs engine vibrations, protecting exhaust pipes from material fatigue.
• Easy Replacement: The simple design allows for quick removal of the old seal and installation of the new one without special tools.
• Durability: The material is resistant to high temperatures and oil action, ensuring a long lifespan in harsh marine conditions.

Remember that regular inspection of exhaust rubbers is key to maintaining your boat's performance. Contamination or cracks can lead to dangerous exhaust gas leakage into the hull. Replace parts with new ones according to manufacturer recommendations, using components like SIERRA 18-2748.
