Exhaust Rubber Gasket SIERRA 18-2780-1

Compatibility

Ensure your outboard motor runs reliably by choosing the original SIERRA 18-2780-1 exhaust rubber gasket. This critical exhaust component plays a fundamental role in vibration isolation and noise reduction for your propulsion unit. Designed for a wide range of engines with displacements from 3.0L to 8.2L, including popular DPS-A and DPX configurations, this high-quality seal effectively prevents exhaust leaks and water intrusion, extending engine life and ensuring safety on the water.

Since part compatibility depends on various factors, we recommend verifying fitment using catalog number 18-2780-1 or the original OE number. If you have any doubts about compatibility with your specific engine model, please contact our customer support team to select the correct part.

Proper replacement of the exhaust gasket guarantees system integrity. Before removing the old seal, ensure the engine is cool and exhaust pipes are clean. Install the new rubber gasket carefully, ensuring proper alignment without folds that could damage the material. Regular inspection of this part prevents costly repairs.
