Can't tell from the picture, but does this installation have the aluminum
duct inserts that Sam James sells? They have a bell mouth that matches the
cowl hole but neck down to a smaller size duct. He has made them in a
number of sizes and the figures I mentioned are what he told me are the latest
& greatest that he has tried. As always, YMMV.

Tracy; The enclosed picture of the Sam
James cowl is where I got the idea of the five inch cowl openings. Sorry
It appears that it goes straight into the plenum and the ruler says 4
1/2"s. I took this picture in October, of Roy Pinners RV-6.
