It's the Law: Required Equipment

Ventilation Systems

The purpose of ventilation systems is to avoid explosions by removing flammable gases. Properly installed ventilation systems greatly reduce the chance of a life-threatening explosion.

• All gasoline-powered vessels, constructed in a way that would entrap fumes, must have at least two ventilation ducts fitted with cowls to remove the fumes.
• If your vessel is equipped with a power ventilation system, turn it on for at least four minutes both after fueling and before starting your engine.
• If your vessel is not equipped with a power ventilation system (for example, a personal watercraft), open the engine compartment and sniff for gasoline fumes before starting the engine.

Backfire Flame Arrestors

• Because boat engines may backfire, all powerboats (except outboards) that are fueled with gasoline must have a U.S. Coast Guard—approved backfire flame arrestor on each carburetor.
• Periodically clean the flame arrestor(s) and check for damage.

Mufflers

• Vessel operators may not hear sound signals or voices if the engine is not adequately muffled.
• All vessel engines must be equipped with an effective muffling device.
• Many South Carolina lakes have specific laws prohibiting boats or PWCs from making excessive or disturbing levels of noise.
