I suspect that C&C decided to just put blowers everywhere and then not have to worry about what kind of engine got installed. Also diesel engines can be smelly and maybe they thought it was nice to have a way to pull the fumes out. I have never ever heard of a diesel leak causing an explosion, but many a boat has burned when a fuel leak encountered a red-hot turbo, Prior to turbochargers being water cooled this was a cause of numerous fires. BTW – there is no way a diesel engine can reduce the oxygen in your boat without reducing the air pressure in general. If your enclosure is tight enough to hold vacuum it is way better than most!

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...

I just today removed the rusted out ignition-protected blower in the stern of my boat, which looked original. It had been disabled a while ago by a prior owner (had no hoses attached, and the electrical wires aren't live) but never completely removed. https://drive.google.com/file/d/0BxfHpwssU_6NdlFtMXJRRTdIZzg/view?usp=sharing West Marine has a page saying blowers are a must for gasoline, less so for diesel but sometimes still advisable for air supply to the engine. But our engine compartments are so huge and leaky (compared to many more modern boat designs - like a Jeanneau with an insulated below-companionway-stairs engine installation) that it seems quite unnecessary. Maybe that was the thinking of the times in the 80's? -Patrick 1984 C&C LF38 Seattle, WA On Thu, Dec 24, 2015 at 8:27 AM, <cnc-list-requ...@cnc-list.com<mailto:cnc-list-requ...@cnc-list.com>> wrote: ---------- Forwarded message ---------- From: Nate Flesness <nateflesn...@gmail.com<mailto:nateflesn...@gmail.com>> To: "cnc-list@cnc-list.com<mailto:cnc-list@cnc-list.com>" <cnc-list@cnc-list.com<mailto:cnc-list@cnc-list.com>> Cc: Date: Wed, 23 Dec 2015 16:59:18 -0600 Subject: Re: Stus-List Proper Blower Installation - 30 mki My 1980 30-1 has two hoses connected to the stern vents. One hose is blower exhaust, the other runs forward to just aft of the engine and sits there - air intake. I turn the tops accordingly. Very likely this is original. The hose diameter fits tightly on the vent base, so 3" I.D.?
