Helpful Check Lists
Print and use these checklists, and do not operate your boat without doing the following:
Each Time You Go On A Boat Trip
Make sure you know where CO exhaust outlets are located on your vessel.
Educate all passengers about the symptoms of CO poisoning and where CO may
accumulate.
When docked or rafted with another boat, be aware of exhaust emissions from the other
boat.
Confirm that water flows from the exhaust outlets when the engines and generator (if
equipped) are started.
Listen for any change in exhaust sound that could indicate an exhaust component failure.
Test the operation of each CO alarm by pressing the test button.
Once A Month
Make sure all exhaust clamps are in place and secure.
Look for exhaust leaking from exhaust system components. Signs include rust and/or
black streaking, water leaks, or corroded or cracked fittings.
Inspect rubber exhaust hoses for burned, cracked or deteriorated sections. All rubber
hoses should be pliable and free of kinks.
Clean the bilge and all bilge components with a mixture of bleach and water. Then,
follow up by misting the bilge and components with WD-40. This includes but is not
limited to the hoses, seacocks, pumps, connections, clamps, air conditioner pumps,
generator (if equipped), etc.
Once A Year
Have a qualified marine technician:
Replace exhaust hoses if cracking, charring or deterioration is found.
Ensure that your engines and generator are properly tuned and well maintained (if
equipped).
Inspect each water pump impeller and the water pump housing. Replace if worn. Make
sure cooling systems are in working condition.
Inspect all metallic exhaust components for cracking, rusting, leaking or loosening. Be
sure to check the cylinder head, exhaust manifold, water injection elbow and the
threaded adapter nipple between the manifold and the elbow.
Clean, inspect and confirm proper operation of the generator cooling water anti-siphon
valve (if equipped).
Spray CRC on all of the connections behind the console.
