Lycoming Engine Mount Support Bushing

The Lycoming Engine Mount Support Bushing is designed to provide secure engine support and vibration isolation for select Lycoming aircraft engines, including engines used in airboat applications.

Manufactured from durable rubber, this conical-style bushing helps absorb engine vibrations, reduce metal-to-metal contact, and maintain proper engine mounting support during operation.

Ideal for replacing worn, cracked, or deteriorated engine mount bushings during routine maintenance, engine rebuilds, or airboat engine installations.
