## 🔌 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
