Damage to the pipework and fittings of the engine, which could lead to fuel leaks, can be minimised by ensuring that the engine is securely installed and not able to move in any direction, other than the movement allowed by flexible mounts. This will also help ensure that the engine linkages don't become damaged which could lead to loss of control of the boat if the engine ceased. The engine mounting system must not show any obvious signs of damage such as corrosion, other deterioration, bolt or engine foot fractures. [2.20]
