Before each boating trip, you should:
- Make sure you know where the exhaust outlets are located on your boat.
- Educate all passengers about the symptoms of CO poisoning and where CO may accumulate.
- Confirm that water flows from the exhaust outlet when the engines and generator are started.
- Listen for any change in exhaust sound, which could indicate an exhaust component failure.
- Test the operation of each CO detector by pressing the test button.
At least monthly, you should:
- Make sure all exhaust clamps are in place and secure.
- Look for leaks from exhaust system components. Signs include rust and/or black streaking, water leaks, or corroded or cracked fittings.
- Inspect rubber exhaust hoses for burns, cracks, or deterioration.
At least annually, have a qualified marine technician check the engine and exhaust system.
