Mufflers and Engine Shut-Off Lines

Mufflers

Pleasure craft operators may not hear sound signals or voices if the engine is not adequately muffled. According to the Small Vessel Regulations:

• The exhaust of every pleasure craft that is equipped with a motor must be muffled effectively while operating within five nautical miles (9.26 km) of shore.
• Your pleasure craft is exempt if:
• It has an unmodified stock outboard engine or…
• It was built before January 1, 1960, or…
• It is being used in an official competition, or in formal training or final preparation for an official competition.

Engine Shut-Off Lines

The purpose of an engine shut-off line is to shut off the PWC’s engine if the operator falls off the PWC or is thrown from the proper operating position.

When operating a PWC, you must attach the engine shut-off line securely to your wrist, lifejacket, or PFD. This ensures that your PWC stays close if you fall overboard.
