Cowl-Vents, Precision Cast Stainless Steel
(cast = free of welded seams = prevents corrosion)

Each cowl vent includes a thumb screw to adjust the direction of the cowl vent mouth (the vent can be rotated to reduce air intake during inclement / colder weather).

Optional deck plate kits include an "O" ring seal, cover, and a stainless steel key. The cowl vent can then be removed from the deck plate, and a deck plate cover can be installed to totally seal off the opening.  Deck plates are predrilled for installation with four #10 screws (screws not included).
