🔌 Function

Carries the engine's weight on rubber so vibration and small movements are absorbed instead of being passed straight into the hull.

⚠️ Common Signs of Failure

• More vibration through the boat than the engine used to give
• Rubber cracked, perished or split away from the metal
• Engine sitting low or leaning on one side
• Shaft alignment drifting out between checks
• Oil or fuel contamination softening and swelling the rubber

🛠️ Service Notes

• Renew mounts as a set, since one new cushion among worn ones throws the engine out of line
• Recheck and reset shaft alignment after fitting, and retorque once the rubber has settled
