3853805 Rubber Cushion Volvo Penta | Genuine Used Part

🔧 Product Description

Genuine Volvo Penta / OMC Cobra Front Engine-Mount Rubber Cushion - Part Number: 3853805

A genuine rubber isolation cushion used in the forward engine-mount assemblies of numerous Volvo Penta petrol sterndrive packages. The same mount architecture was used on OMC Cobra installations, making OMC 0983903 / 983903 the principal cross-brand reference. The cushion supports the engine while isolating hull vibration and allowing final engine-alignment adjustment through the surrounding bracket and fastener assembly.

⚠️ Common Signs of Failure

• Rubber separates from the metal centre
• Engine settles and coupler alignment changes
• Excessive vibration reaches the hull
• Mounting stud sits off-centre or bottoms out
• Rubber is oil-soaked, cracked or hardened
• Repeated coupler or gimbal-bearing wear occurs
