Hi everyone,
Went on a fishing trip last night and the carbon monoxide at the helm was very strong.  I was cruising into the wind @20 MPH so not sure how it could be coming from the exhaust ports?  It was so strong that my Carbon Monoxide detector went off inside my cabin.  (I did have the companion way door open.)  All exhaust tubes were replaced over the winter so I don't think there is any kind exhaust leak.  I also noticed a strong smell when were trolling but that was just probably wind direction at trolling speed and exhaust coming up and over the side.  
Any experience or thoughts on this?  Don't want to risk anyone passing out on board.
Thanks as always,

Was your canvas up? Do you have a generator? I would definitely re-check all of your exhaust ports and connections.
