An Engine Mount Loose occurs when engine mountings—metal and rubber components securing the engine to the chassis—detach, wear out, or suffer from broken mounts. In boats, this might affect the port side engine or entire engine setup, causing engine movement and a loss of engine mounting effectiveness. For cars, it’s often tied to the engine block or subframe bolts loosening due to aggressive driving or fluid leaks like engine oil degrading the rubber aspect.
Common Causes

Aging Over Time: Natural rubber in motor mounts deteriorates, leading to a loose lag bolt or lag screws failing.
Poor Installation: Incorrectly fitted angle mounts or a piece of angle iron can cause an Engine Mount Loose.
