🚤Carbon monoxide (CO) is a safety risk with gas-powered boats. It can build up quickly and is impossible to see, smell, or taste. Keep fresh air flowing, stay away from exhaust areas, and test your CO alarms before every trip. Move to fresh air and call if you or a loved one has been exposed to CO: 1-800-222-1222📲
⛽Symptoms of CO poisoning include headache, dizziness, nausea, weakness, confusion, and loss of consciousness. These symptoms can become serious and lead to death if left untreated.
Recreational boaters may be exposed to CO while:
🚫Riding or sitting near the stern while the engine is running
🚫Riding on swim platforms
🚫Sleeping in enclosed cabins without proper ventilation
🚫Running a generator while anchored or docked
🚫Being near another boat’s exhaust in a marina or cove
Inboard engines, especially those on larger recreational boats, can create higher CO risks because exhaust may accumulate in enclosed cabins, under swim platforms, or in areas where people gather near the stern. Exhaust gases may be drawn back into the boat's cockpit or cabin while underway, exposing passengers to CO.
Prevent CO poisoning by:
✅Always swim or play at least 20 feet away from the engine exhaust.
✅Install and regularly test marine-rated CO alarms. Do not ignore an alarm.
✅Know where engine and generator exhaust outlets are located and keep passengers away from those areas.
✅Maintain fresh air circulation throughout the boat at all times.
✅Run exhaust blowers whenever the generator is operating.
✅Never sit, hang, or "teak surf" on the swim platform or stern while engines are running.
✅Never block exhaust outlets.
