I have a full cockpit enclosure on s/v Rainy Days. When motoring with the enclosure in place, the engine's intake air must come from within the enclosure, reducing the oxygen content in the enclosure. I have a new blower but the intake and exit are presently inside the enclosure. I have to modify my enclosure so that its not this way. So, if you ever plan on adding a full cockpit enclosure, you have to pay attention to where the engine's intake air is coming from...
