5.1. Engines and engine compartments

All inboard mounted engines shall be placed within an enclosure separated from living quarters and installed so as to minimise the risk of fires or spread of fires as well as hazards from toxic fumes, heat, noise or vibrations in the living quarters. Engine parts and accessories that require frequent inspection and/or servicing shall be readily accessible. The insulating materials inside the engine compartment shall not sustain combustion. The engine compartment shall be ventilated. The ingress of water into the engine compartment through openings must be minimised. Unless the engine is protected by a cover or its own enclosure, exposed moving or hot parts of the engine that could cause personal injury shall be effectively shielded. Every outboard propulsion engine fitted on any watercraft shall have a device to prevent the engine being started in gear, except: when the engine produces less than 500 Newton’s (N) of static thrust; when the engine has a throttle limiting device to limit thrust to 500 N at the time of starting the engine. Personal watercraft shall be designed either with an automatic propulsion engine cut-off or with an automatic device to provide reduced speed, circular, forward movement when the driver dismounts deliberately or falls overboard. 5.1.6. Tiller-controlled outboard propulsion engines shall be equipped with an emergency stopping device which can be linked to the helmsman.
